When you make the payment, you will see the result of the operation on the screen:

  • Correctly authorized: your card has been charged and the Lumisa account has been credited.
  • Denied: a problem has been detected during the process, for which the payment has not been made.

Yes. At Lumisa we use a Virtual POS system so that your data is protected.

A Virtual POS is a payment gateway with the ability to charge online. It is a very secure digital payment that guarantees the encryption of the information, for example, through the use of SSL security certificates.

Yes. If you provide us with your email, we will confirm that we have received the credit in the Lumisa account.

Changing energy suppliers is a fast and totally free procedure. This is carried out when someone wants to go to another company because they offer better prices or better services. Also, you will not be without electricity during the switching procedure.

If you have decided to contract with Lumisa, we will briefly explain the steps to follow.

If you contract through or through our Customer Service you must follow the following procedure:

1. To make the change to Lumisa, you must provide the following documentation via email or fax at or by calling 900 811 473 or Whatsapp 688 100 100.

  • In the case of a company, CIF of the company.
  • ID of the owner or administrator.
  • Last electricity bill.
  • Bank account number.
  • Contact information. Telephone number and email.

2. Once we receive the documentation, we will send the contract to the shipping address or email address provided. You must keep a copy and return it by email address, or simply make an online signature through our digital signature platform.

3. Once we receive the contract, we will proceed to make the switch. The switch may take between 5 to 7 days depending on the Distributor.

4. You will receive one last liquidation bill from the previous marketer. The first Lumisa invoice will close the billing cycle, the second invoice will begin the natural billing cycle.

So you do not have to worry about anything since we will handle the procedures quickly and efficiently.

If you decide to contract with us, as well as carry out any modification of the contract, you must fill out the online form at and once done, confirm with an online signature.

You should have available:

  • Email, which you will receive to access the online signature.
  • Mobile phone, where a confirmation PIN will be sent.

The steps to follow can also be found in the article "How to sign a contract online in three simple steps." 

The change of supplier has no cost. Although there is the possibility that your former supplier may apply penalties for the breach of the agreed contract period, so it is advisable to consult the supplier if there is a penalty.

It is important that you do not confuse registering a supply with a change of supplier. When we talk about registering, we refer to supplying a point where previously there was no electricity and it has a cost.

No. Under no circumstances will you be without supply during the switch.

Of course, you are free to leave at any time since there is no permanency commitment.

If, once the switch is made, you are not satisfied with our services, we will provide you with everything possible to complete the return process.

You do not need to make any changes to your meter or your installation. The change is administrative, so technically everything remains the same.

The move to the liberalized market means a change of company, but you can contract with a trading company of the same group as your current distributor.

No. As of the date that the supply is with us, your previous company should not charge you for any later date. Although, it is true that you are responsible for paying for the billing cycle prior to the date of change. 

Of course, you can have as many supply contracts with us as you wish. For example, if you have a home address, rental location and company and you want to hire them with us, we will look for the rate that best suits each case, according to the need.

Yes. As a tenant you have the right to choose the electric company that you prefer, in the same way that we choose the telephone company, cable television, internet, etc.

When we talk about installation, we refer to supplying a point where previously there was no electricity. In this case, you have to process the connection file directly with the distributor of your area to obtain the CUPS.

On the other hand, when we talk about changing suppliers, that is when there is already electricity and a contract with a company, but the customer wants to switch companies because the latter offers better services or more competent prices, or because of preference for another supplier. 

In "Difference between signing up and trading" we explain it in more detail.

To register a new supplier, it is necessary to provide technical documentation.

If it is a home:

  • If it is the first occupation, a Low Voltage Electrical Installation Certificate (CIEBT) stamped by an EIC or by the Department of Industry.
  • If it is a second occupation, if there is no prior technical documentation for the installation: a Recognition Bulletin of Low Voltage Electrical Installations, if the previous reduction is over 3 years. This document reflects the main characteristics of your installation, such as the installed power and the maximum admissible power, in addition to guaranteeing the quality of the installation. In the event that the power requested exceeds that allowed, you must provide us with a new Bulletin that you can request from your electrician installer.

On the contrary, if it is a local or common area. According to current legislation, to contract a supply of electric power, the presentation of the following documents is required: Certificate of Electrical Installation in low tension, according to the type of supply, in triplicate copy, issued by the electrician installer who made it and sealed by the Competent Body of the Administration.


Houses in buildings, townhouses or single-family houses 

Commercial premises or offices  CIE CIE/BRIE


Common Services in residential, commercial or office buildings.  CIE CIE

Temporary facilities:



Pumps for lifting or extracting water.  CIE CIE
Other facilities.  CIE CIE

CIE = Certificate of Low Voltage Electrical Installation sealed by an EIC or by the Dpt. Of Industruia.
BRIE = Bulletin for the Recognition of Low Voltage Electric Insations.

An installation company or an authorized installer can issue you the technical documentation that certifies that the installation is correct for the registration of the supply.

The Distributor Company is responsible for supplying electricity to a point of supply without service. It is responsible for reviewing all the technical documentation issued by the installation company, ensuring the safety of the supply point and placing the ICP and / or the relevant meter. They are also the ones that receive the cost that you have to pay for accessing the network. This cost is regulated by the State.

Installing an electricity supply or reactivating one that has not been used for more than 3 years has a cost regulated in Royal Decree 1995/2000 of December 1 that the distributor will charge you through Lumisa:

  • Guaranteed deposit: according to what is established in article 79 of Royal Decree 1955/2000, it is the amount to be delivered, at the time of contracting, for an amount equal to the monthly theoretical turnover corresponding to fifty hours of use of the contracted power. 
  • Access rights: it is paid when contracting a new supply or by increasing the power of an existing supply with an amount of 19,703137 €/kW + VAT.
  • Extension rights: it is paid when using the infrastructure of the distribution company in the case of new supplies, when the power contracted increases or if the supply point has not been used for more than 3 years with an amount of 17.374714 €/kW + VAT.
  • Engagement rights: it is paid when using the infrastructure of the distribution company in the case of new supplies, when the contracted power goes up or if the supply point has not been used for more than 3 years with an amount of ?9.04€ + VAT.
  • Verification rights: paid when carrying out the installation revision with an amount of 8.01€ + VAT. 

As soon as we have all the required documentation, the Distributor takes a maximum of 5 working days to activate a low voltage supply point.

To know how the electric sector works, let's start from the beginning.

The producers are responsible for producing energy. In our country there are different production plants such as:

  • Conventional thermal power plants
  • Nuclear power plants
  • Or alternative energies such as wind farms, photovoltaic power plants.

The carriers are responsible for the transport of energy in high voltage, in our country it is the Electrical Network of Spain (REE).

The distributors remain regulated by the State, and are responsible for maintenance and different areas of the country

And finally we enter: suppliers like Lumisa, who are in charge of buying the energy and billing it to their consumers using the distribution networks.

The grounding, also known as grounding (PAT) is an essential installation in an electrical installation as it guarantees safety and avoids serious consequences to people and electrical equipment.

The grounding installation is the responsibility of the customer, and must ensure that its electrical installation is adequate and at the same time, an authorized technician must certify it through the Electrical Bulletin.

The provisional facilities are those that have a limited duration due to their circumstances. They are provided for in Royal Decree 842/2002, of August 2, which approves the low voltage electrotechnical regulation. They may be:

  • Repair. Those necessary to alleviate an exploitation incident.
  • Work. Those made to allow changes or transformations of the facilities, without interrupting the operation.
  • Semi-permanent. Those destined to modifications of limited duration, within the framework of habitual activities of the premises in which they are repeated periodically (Fairs).
  • Of works. They are intended for the execution of construction work for buildings and the like.

If you want to make a construction from scratch, or some major reform and want to hire electricity only to carry out the construction, it is not necessary that you hire a common Light Rate but that the Distributor Companies have a special type of new installation for these cases.

Once we have issued your first bill with Lumisa, register in the Customer Area to be able to enjoy all its advantages. You will have at your disposal all the exclusive services of My Customer Area:

  • Check your invoices and download them in PDF format whenever you want from your home.
  • Make holder changes or power changes in a simple and fast way.

It is completely free, you just have to register in this link or click on this image.

You can change the password whenever you want in the Personal Data section.

Yes. We advise you to do the procedures online because it is the fastest way and you can attach the online documentation directly.

But if you prefer you can also do it through our telephone number 900 811 473 or our e- mail

In order to make a change of holder, keep in mind that:

  • The change is always requested by the new holder.
  • The new holder becomes responsible for the invoices.
  • The amount of the first invoice is calculated pro rata.
  • We do not charge to change the holder, but in some cases you may have to pay your Distribution company.

The request to change the holder can be processed online in a very fast and simple way through this link. You only need to have on hand a recent invoice, the bank account and the DNI of the new holder.

If you want to discuss it in more detail, we have an article in our blog "Make a change of holder of the light" with the step by step to follow.

Yes, it is possible. If you never exceed limits you probably have room to lower the power. If, on the other hand, they power jumps often, you are already at your limit. In the event that you add new appliances or increase the use, you will probably have to contact your electricity company to consider an increase in power.

Following Royal Decree-Law 15/2018 on urgent measures for the energy transition and consumer protection, it will be possible to contract the power in 0.1 kW sections, with the elimination of the normalized tranches that limited the contracting to these values.

The power you need will be determined by several factors. A very intuitive way to know if our power is inadequate is the following:

  • Turn on all the appliances in your house at once. If the power does not jump, it means that surely you have a power over what you need and you have some margin to decrease it.
  • If the daily use of your electrical appliances frequently leads to losing power, the power you are using is too little and you will have to increase it to enjoy more comfort.

See our article "How to calculate the electrical power you need in your home" to solve your doubts on this topic.

To make a change of power you must fill out the power change form on this link.

The following will be necessary:

  • Holder's electricity supply address.
  • Personal data of the administrator.
  • Current and new contracted power.
  • CUPS, which appears on your invoice.

In the same way, you can contact us via email at requesting a power change request form. Once it is filled out and signed, it will be resent to the same email.

If it is a reduction of the power, you will have to pay a small cost of € 9.04 plus VAT due to the entitlement rights.

On the other hand, if it is an increase in contracted power, the expense will be higher since they must be paid:

  • Right of access with an amount of € 19,703137/kW requested plus VAT.
  • Extension fee with an amount of € 17,374714/kW requested plus VAT.
  • Engaging right with an amount of € 9.04 plus VAT.

The change of power holds a cost for the user of the point of supply since they will have to pay a series of rights and managements carried out by the Distributor, which will be passed on in a single invoice.

If you want to know more about this, here is the article "How much does it cost to change the contracted power?".

According to Royal Decree 1164/2001, it is only allowed to process one modification of the power and/or per year per holder.

Therefore, if in less than a year a second modification is requested again under the same ownership, it will be denied and they will have to wait the indicated time to make a new modification.

If you need to update your payment details, you must fill in the following SEPA Debt form.

If the owner of the new bank account is the contract holder, you only need to send us the IBAN number (20 digits). If you are not the holder, in addition to the IBAN number, you need to send us the identification document (DNI, NIF, CIF, passport) of the owner of the new bank account. 

Remember that you can only modify the direct debit with a minimum of 21 calendar days before the date of issuance of the invoice to allow time for the modification of data with the bank and the charge in the new account.

Or if you prefer, you can provide us with the new information by sending an email to indicating the CUPS number and the data you want to modify. 

You cannot make an ownership change if there is a debt. When the debt is paid, then you can make the change of ownership. For these cases there are two possibilities:

  • Change of owner without subrogation: the new owner is separated from any responsibility incurred by the previous owner.
  • Change of owner with subrogation: the new holder assumes all the conditions agreed in the contract by previous holder.

Keep in mind that if there are outstanding debts, until they are satisfied, the change of ownership cannot be made.

In accordance with the article 52.4.i) og the law 24/2013, from 26 December, of the Electric Sector, essential supplies are considered "those domestic supplies in which there is documentary evidence formalized by medical staff that the supply of electrical energy is essential for the feeding of a medical equipment that is essential to keep a person alive. In any case, these supplies will be limited to persons in their habitual residence."

To guarantee the compliance of these requirements you must provide the following documentation to our email

  • Current medical certificate confirming the existence at the point of supply of an indispensable electrical device to keep a person alive.
  • Certificate of registration that accredits that the person to whom the medical equipment is destined resides at said point of supply.

If you need to prove that you are up to date with all the payments on your invoices with Lumisa, fill out our form and we will send you a document through your email that will certify that there are no defaults on the date the certificate is issued.

Through our client area you can request the quarterly amounts of form 347 according to Order HAC/1148/2018, of October 18. The application period for this procedure is from January 1 to the last day of February.

Remember that form 347 is mandatory and is submitted in February of the following year and ends on February 28.

Lumisa offers rates adapted to Circular 3/2020 of January 15 2020, Order TED/371/2021 of April 19 and the Resolution of March 18 2021 of the National Markets and Competition Commission, which can be adjusted to your consumption needs.

The main changes to Circular 3/2020 are:

  • The 2.0A / DHA and 2.1A / DHA rates with contracted power equal to or less than 15 kW will be renamed 2.0TD.
  • The 3.0A tariff with contracted power greater than 15 kW will be renamed 3.0TD.

The most suitable rate for you will depend on the type of supply, if it is a home, the type of home, the people who live in it, and what they spend, a small premises, a large company, among others.

If you are not yet a client of ours and you have any questions about what type of rate should be contracted, do not hesitate to contact us and we will assist you through the free phone number 900 811 473, as well as by email

As established in Circular 3/2020 of January 15, 2020, Order TED / 371/2021 of April 19 and the Resolution of March 18, 2021 of the National Markets and Competition Commission, the new Access fees that will be applied from June 1, 2021.

Rate 2.0TD

All consumers will have differentiated prices by time slots, both for power and consumption.

Consumption will be differentiated into three periods:

  • The peak period: with the highest price, from 10 in the morning to 2 in the afternoon and from 6 in the afternoon to 10 at night from Monday to Friday, excluding holidays.
  • The flat period: a less expensive price from 8 to 10 hours, from 2 to 6 in the afternoon and from 10 to 12 at night.
  • The valle period: with a reduced price, it includes night hours (from 0 am to 8 am) and all hours on Saturday and Sunday and national holidays.

The power differs in two periods:

  • Peak power from 8 in the morning to 24 at night.
  • The valle power from 24 at night to 8 in the morning, and all hours on Saturday, Sunday and national holidays.

Rate 3.0TD

The hourly discrimination of 3 periods will go to 6 periods (in power and energy), and instead of dividing the year into two seasons (winter and summer), the different months of a year will be divided into 4 seasons:

High season: January, February, July, December.

  • Punta (P1): 9am - 2pm, 6pm - 10pm
  • Llano (P2): 8am - 9am, 2pm - 6pm, 10pm - midnight
  • Valle (P6): 24h - 8h

Mid-high season: March, November.

  • Punta (P2): 9am - 2pm, 6pm - 10pm
  • Llano (P3): 8am - 9am, 2pm - 6pm, 10pm - midnight
  • Valle (P6): 24h - 8h

Mid-low season: June, August, September.

  • Punta (P3): 9am - 2pm, 6pm - 10pm
  • Llano (P4): 8am - 9am, 2pm - 6pm, 10pm - midnight
  • Valle (P6): 24h - 8h

Low season: April, May, October.

  • Punta (P4): 9am - 2pm, 6pm - 10pm
  • Llano (P5): 8am - 9am, 2pm - 6pm, 10pm - midnight
  • Valle (P6): 24h - 8h

The allocation of the new rates is automatic, depending on the voltage level to which the consumer is connected and, for low voltage consumers, according to the contracted power.

Consumers who switch to the 2.0TD toll will be applied the same power for the peak and trough period that will correspond to the power they currently have contracted.

To consumers passing the 3.0TD toll:

  • The power of the period P1 will correspond to the power that they have contracted in the peak period.
  • The power of the period P2, P3, P4 and P5 will correspond to the power that they have contracted in the valle period.
  • You must have the VPSC electricity rate (with or without time restriction) and a contracted power equivalent to or below 10 kW in your usual residence, which is contracted through reference marketers. The Social Bonus cannot be benefitted through Lumisa.
  • You will need to fulfil certain requirements in order to be classified as a vulnerable customer (25% discount), severely vulnerable (40% discount), severely vulnerable customer at risk of social exclusion or vulnerable customer because of COVID-19 (25% discount) established in

Information obtained from the web portal of

The PVPC rate is the Voluntary Price rate for the Small Consumer. This is the electricity rate that belongs to the regulated market, that is, the one that has electricity prices set by the Government. The PVPC replaces the previous Last Resort Rate (TUR) and is regulated by the Ministry of Industry, Commerce and Tourism. It is applied to the bills of those consumers with a contracted power not exceeding 10 kW.

With the new PVPC system, the way of calculating the payment only for consumption during a billing period is modified.

Lumisa offers two options regarding the type of rate according to your needs.

  • Indexed rate: With the indexed rate, you will pay the energy consumed at the price set by the electricity market, plus a small fee of € 3.9 / month to cover our management expenses.
  • Fixed rate: With the fixed rate you will always pay at a fixed annual price for the energy you consume and the contracted power without worrying about increases or decreases in the price of electricity.

The indexed electricity rate is the one that offers the same price of the electricity supply as purchased by the marketer in the Market, plus a small fee of € 3.9 / month to cover our management expenses. That means that the price of electricity will vary every hour and the customer will have 24 different prices per day.

The price of energy is stipulated by Red Eléctrica Española and the price of power is always the same and is indicated in the Official State Gazette (BOE).

At Lumisa we offer you energy at cost price, therefore, this is the margin we have to cover management costs and, no more, no less.

The indexed rate has certain advantages that we explain below:

  • You will pay at all times for the electricity you consume at the wholesale market cost price.
  • You will be able to adapt your consumption to the different tariff periods by shifting the activities of great electricity consumption at these times.
  • The risk premiums of the marketers are eliminated.
  • You will be able to see at all times the price of energy stipulated by Red Eléctrica Española.

To better understand the difference between the fixed price and the indexed price, we must take into account a concept, Risk.

With the indexed rate, the price of energy is the one set by the electricity market. In this type of rate, the risk is assumed by the user since the fluctuation of the electricity market will be reflected in his bill.

On the other hand, in the fixed rates, the marketer marks a fixed price with the client that applies for a certain time (normally one year). The trading companies are the ones that assume the market risk and apply premiums to their rates. In this type of contract, the fixed price will largely depend on when the fixed price of electricity is negotiated.

The fixed rate is the one for which you will pay a fixed price for each kWh that has been consumed, previously established in the contract with Lumisa.

For more information see the Pricing Policy.

The telemanagement counter is an intelligent reader of electricity consumption that can be replaced by traditional electric meters. Its advantages, among others, are that it can read consumption remotely, make real readings, and function at a faster pace.

The Royal Decree 1110/20017, Order ITC 3860/2007 and IET 290/2012 obliges the distribution companies to replace the current meters, with power less than or equal to 15 kW for meters with telemanagement capacity before 2018.

The cost of renting equipment is set by the Ministry of Energy, Tourism and Digital Agenda, which is regulated by Order IET / 1491/2013, of August 1, which reviews the electric power access toll.

Therefore, the supplier will charge the rental of equipment, although it really is a payment that is paid to the distributor because it is responsible for the operation and maintenance of the same equipment.

These prices will depend not only on the price of the equipment but also on the costs associated with its installation and maintenance. Therefore, the average cost for renting domestic electricity meters is € 0.81 for single-phase meters with time discrimination and with the possibility of telemanagement. And € 1.36 for three-phase meters with time discrimination and with the possibility of telemanagement.

According to Royal Decree1718 / 2012 of December 28, it is established that the reading of the electricity meter will be performed by the Distribution Company responsible for their corresponding area. The reading will take place with a bimonthly periodicity, which will be brought to the supplier company's knowledge.

In the case of having an intelligent meter or telemetry, the reading will be done on a monthly basis.

If the Distributor Company in charge of reading your electricity consumption cannot access the measurement equipment to carry out the reading, you must give a notice of impossible reading in which you indicate a telephone number and a web address where you can facilitate the reading of your meter and a deadline.

Therefore, if you do not facilitate the reading of your meter within the indicated period, the Distributor can estimate the electricity consumption. The estimated reading is a calculation made by the distributor of the period consumption, which has not been possible, from the actual reading of your meter.

The Distributor makes the estimate as close as possible to the real monthly consumption of the client. However, if it has been estimated more or if it has been estimated less, it will be regularized with the actual readings in the next bill and with the price corresponding to each period.

If you wish to have a real monthly reading it will be necessary that you send us the reading filling in the reading form or through the email to provide us with the reading.

We will need to identify your supply point, so it is also necessary that you indicate the CUPS number (Universal code of the supply point).

ICP stands for Power Control Switch. The ICP controls the power consumed. Therefore, if the power consumed is higher than the contracted one, it starts operating by cutting off the power supply.

The maximeter is a device that measures the maximum power of all the powers between periods of 15 minutes of an electrical supply for contracted powers greater than 15 kW. It records the parameters of:

  • Active Energy (kW)
  • Reactive Energy (KVArh)
  • Maximum power used (kW)

Unlike the IPC, it avoids cutting the power supply in the case of exceeding the contracted power.

At Lumisa, we manage the registration of the customer's electricity meter, providing the technical documentation of the electricity meter.

The technical documentation of the Electricity Meter will be provided by the brand. However, if you have lost it or do not currently have it, it can be requested again at a cost of € 60 and by sending a photograph of the Electricity Meter placed by an authorized installer.

Once registered, in Lumisa the change is requested from the Distributor and it will be reflected in your electricity bill through the Electricity Meter number.

To distinguish whether you have a single-phase or three-phase installation, just look at the ICP, which is in the first position within the electricity box.

If the switch is double, it means that your installation is single-phase. If the switch is triple or higher, it means that your installation is three-phase.

If you are one of those who continue to receive bills with an estimated reading, you must communicate your meter reading yourself and thus avoid avoid being billed for an estimated reading. To send us an your real reading it will be necessary that:

  • Access your counter and take a photo of the consumption made, where you will also detail the date.
  • You will need to send us your reading within 10 working days before the new billing period starts.
  • Attach the photo along with your CUPS number through our reading form or by email or via WhatsApp 688 100 100. 

However,  keep in mind that:

  • The reading made by a Technician will always have priority.
  • If the Technician can not access the meter, the readings that you have contributed will be taken into account.
  • In the case that you do not send us readings, an estimate will be made.

An estimated bill is just as valid as one with a real reading, however, keep in mind that it is provisional and will be regularized semiannually once the actual consumption is available. 

You can choose the shipping method between post mail shipment to your point of supply or fiscal address. Or to the email address you provide us.

Also, if you join Lumisa and you register in the Customer Zone you will be able to see all your already issued bills and download them whenever you want.

If you have questions about your bills you have several options:

At Lumisa we have some payment methods:

  • Bank Domiciliation. If you opt for direct debit, you must provide us with a valid bank account number.
  • Pay online. You can pay your bills conveniently and securely with a credit or debit card through our online payment form for free.
  • Transfer. By making a transfer to the account numbers we provide, with a maximum period of 5 working days prior to the payment due date. 
  • Barcode. Locate the barcode on your invoice, scan it, enter the amount to pay and make the payment.

In most cases the payment of electricity is usually made by direct debit. In this case, if the payment is made late, LUMISA will proceed to notify payment of the same by mail and burofax. 

In case of non-payment by the Client, LUMISA may process in accordance with current regulations, the suspension of the supply if twenty (20) calendar days have elapsed since the payment had been required, through presentation to the collection to the financial institution where the Client has domiciled the payment of the invoice or through the deposit into account of the bank accounts provided to the Client, and this would not have been paid in full.

The power term in the electric bill is the price that the user pays for this contracted power, which is multiplied by the number of kilowatts (kW). It is a fixed concept that has to be paid even if no consumption is made.

The term of energy is the variable cost according to the consumption made. It is the result of multiplying the energy consumed during the billing period corresponding to the price of the term of the contracted energy.

The Special Tax on Electricity falls on the consumption of electricity and taxes the supply of electric energy for electric consumption, as well as the consumption by the producers of that electricity generated by them. The percentage of this tax is 5,113%, applied to the power term and the consumption term.

The proceeds from the Electricity Tax are allocated to public funds, in charge of sectors such as health or education.

It is the amount owed to the Distributor when using its electrical networks and transfer energy to your point of supply.

This is the amount relative to the actions carried out by the Marketer on the basis of unpaid bills within the period established in the General Conditions.

The electronic billing service allows you to access the contents of your bill online in electronic format, at no additional cost. The electronic bill has the same information as the bill you receive on paper and it can be displayed with the same appearance.

You will receive your bill by email in PDF format and you can view it and download it to your computer at any time.

The registration in the Electronic Billing service will be done through the Contracting form by accepting the receival of bills through the email provided by the client.

If you wish to receive the paper invoice again, you can request it through the Customer Area or by sending an email to

The SEPA (Single Euro Payments Area) Mandate is the direct debit order that the customer authorizes and agrees to Lumisa to charge in a certain bank account.

It has some characteristics: 

  • Private agreement between the issuer and debtor (must contain the identification details of the customer, the debtor, the service and the consent of the debtor to make the payment).
  • Signed by the holder of the debit account.
  • In force on the date of presentation of the payment.
  • A standard model does not exist.

You can direct your payments with Lumisa by filling out our form of modification of payment method.

In this case, we recommend that you verify that you are not the only point of supply without service. If there are more neighbors without service, you have to call the distributor to communicate the incident, since in this case the fault lies with the external network.

If you are the only one affected, it means that the fault is inside your facilities. In this case, you have to call an electrician for repair since the distributor is not in charge of the incident.

If once activated the power control by your Distributor "leapt" the leads, it is because the power demanded exceeds the power currently contracted. And therefore the new device would interrupt temporarily the power supply.

In order to restore it immediately you must follow a series of steps:

  • Disconnect any of the appliances, since the contracted power limits the amount of appliances that we can connect at the same time.
  • Open the electrical panel and check that all switches are raised, including the general.
  • If one is down, it is possible that you have some problem in your installation. In this case, we recommend that you consult with an authorized installer.
  • Turn down the main switch and wait for 3 seconds. After this time, upload it again.
  • In case the power supply is not restored, wait a few minutes and repeat the previous steps. The normal thing is that you have electricity again. If this is not the case, it may be a programmed cut or a fault.

If once you have made these simple steps, you continue to lose power often, you most likely have to increase the power contracted by contacting your dealer. Or it may also be due to a fault in your installation, so you should contact an authorized installer.

As the General Conditions specify, in case of non-payment by the Client, LUMISA may process, in accordance with current regulations, the suspension of the supply if twenty (20) calendar days have elapsed since the payment had been required, through presentation to the collection to the financial institution where the Client has domiciled the payment of the invoice or through the deposit into account of the bank accounts provided to the Client, and this would not have been paid in full.

If, in spite of our legally foreseen initiatives, the payment of the pending invoices is not made within the legally foreseen term and with a legally foreseen notice of 5 calendar days, the power supply in question will be cut off.

Once the cut has been sent to the Distributor in your area, in order to re-discharge the light, the invoices pending payment previously required must be paid. That is why once we receive the payment of the same the electricity supply will be resumed in 24 hours, having to pay the reconnection rights to the network, billed by the Distributor of your area in the next invoice.

As indicated in Royal Decree 1955/2000, the customer must pay the cost of reconnection of an amount equivalent to double the engagement rights (9,04€ without VAT).

If after more than two months and the amount of the pending invoices has not been paid, you will be definitively discharged.

It is due to an anomaly detected in the meter, that is, it stops recording the kW consumption or part of it. In order to clarify what happens the company opens the file to go to check the measurement equipment and see if it is due to technical failure or possible fraud.

When there is an irregularity in your consumption and you see a lot of disparity between the kW consumed and those invoiced, a file is opened to investigate what may have happened and if the possible fraud is real.

In the case of receiving a letter of this type you will have to contact the distributor, their number and different ways of contact will appear in the same letter. They will inform you of what you have to do to manage your case.

The marketers here can not do anything and you will have to process everything on your own

Once the file has been processed, if fraud has been found, the corresponding fine will have to be paid and then the supply will be standardized in accordance with current legal regulations.

Normally, the meter is paid as rental of measure month by month, if it is that way, the distribution company must proceed to normalization to update it.

Otherwise, if you have an own accountant, the work necessary for this will be carried out by the user, and the distributor must be notified once it has been finalized so that the latter can verify it.

You have to go to your marketer who will inform you how to pay the amount that corresponds to the amount of kW you received in the first letter.

When paying, will proceed to restore the electricity supply normally.

According to the following law Compliance with individual supply quality (artículo 104 Real Decreto 1955/2000):

The distributor shall be obliged that the time and number of unforeseen interruptions greater than three minutes of each calendar year does not exceed the following values, depending on the area where the supply is located:


  Number of hours Number of interruptions
Urban zone 3,5 7
Semi-urban area 7 11
Concentrated rural area 11 14
Scattered rural area 15 19

For consumers connected to networks with a voltage greater than 36 kW, they shall be assimilated to the thresholds defined in urban areas.

LOW VOLTAGE (less than or equal to1kW)

  Number of hours Number of interruptions
Urban zone 5 110
Semi-urban area 9 13
Concentrated rural area 14 16
Scattered rural area 19 22

Modified by the R.D. 1634/2006 of December 29, which establishes the electricity tariff as of January 1, 2007 Consequences of non-compliance with individual quality of service (artículo 105 Real Decreto 1995/2000):

The distributor is responsible for compliance with the individual quality levels with each of the consumers connected to their networks.

Failure to comply with these values will determine the obligation for distributors to apply to the billing of consumers connected to their networks the discounts regulated in the same legislation, within the first quarter of the year following the breach. Therefore, where the distributor fails to comply with the values for the continuity of individual supply, they shall apply the following discounts:

Consumers at a rate:

  • If the breach is due to the number of interruption hours, an annual discount will be applied to the consumer billing in an amount equivalent to the consumption of their average annual invoiced power, for the difference between the number of interruption hours prescribed by regulation, valued at five times the price of the kWh corresponding to its contracted rate, with a maximum of 10% of its annual turnover.
  • If the breach is due to the number of interruptions, the discount in the annual invoicing will be equivalent to the consumption of its average annual invoiced power, for the number of interruption hours valued at the price of the kWh corresponding to its contracted rate for the difference between the actual number of interruptions, except set by regulation, divided by eight, with a maximum limit of 10% of its annual turnover.
  • If both indices are breached, the most favorable for the consumer will be taken.

If you have had a power outage caused by a breakdown in the network you can claim the damage suffered on your devices, damaged food, among others. Therefore, In Lumisa we give you the key to make a claim with all the documents that will be requested.

1. Contact the Distributor.

Inform the Distributor of the supply cut, registering an incident / file number. In the same way, we must request a certificate / report of quality in which the events occurred, the failure in the network and the date and time it was restored are exposed.

In Lumisa we help you to request the quality certificate, as well as to contact the Distributor.

2. Make an accounting report of losses if it is a business.

Have an accounting report comparing the sales and profits obtained by the business during a period similar to the time in which the breakdown or electrical interruption occurred, in order to prove the loss of profits.

Law 50/1980, of October 8, on the Insurance Contract, specifies that for the loss of profit insurance the insurer undertakes to indemnify the insured for the loss of the economic performance that could have been achieved in an act or activity of not having occurred the incident described in the contract.

3. Make an inventory attaching invoices or purchase tickets.

You must make an inventory of all those household appliances and food products that have been damaged, as well as the expert report of them, certificate of expert in food handling, purchase or repair invoices, documents or photographs that accredit it.

It is recommended that you save all tickets, purchase invoices and delivery notes of your appliances, as well as documents that can prove the damage or loss.

4. Contact your Insurer and claim damages.

Contact your insurance company if you have an insurance policy with the guarantee of Electrical Damage. The quality certificate must be attached (failing that you can provide the file number or incident if you did not have said certificate).

It is convenient that you review your home or business insurance policy, as it sometimes covers the loss of food if you suffer a power outage.

From Lumisa we do not recommend the discharge of water, electricity and gas supplies, since they are considered basic elements in a dwelling and would make the dwelling as not habitable and, therefore, the complaint filed for occupation of a dwelling would be dismissed. Such a decision may result in a complaint to the owner for lack of coercion under article 620.2 of the Criminal Code, which carries a fine of 10 to 20 days. The reason for this, according to jurisprudence, is that it would be the cause of the shortage of a primary resource to people in a vulnerable situation.

The most advisable solution is to make a complaint with legal title of the occupation of your dwelling or premises through two ways:

  • Civil proceedings (Article 430 of the Civil Code): is the recommended way by the lawyers, in this case and through the latest legal reform that has entered into force on 2 July 2018, it will not be necessary to identify the squatters. These squatters may oppose the eviction only if they can present a legal title entitling them to remain in the dwelling, with a maximum period of 10 days to present it.
  • Criminal proceedings  (Article 245 of the Criminal Code): This type of complaint must be directed against specific individuals, which will lead to an investigation into the identity of the squatters. In addition, criminal proceedings have different stages involving different courts, which lengthens and complicates the process.

Only in cases where the lessor can prove that he is not acting coercively is when the lessor does not pay to the supply company because he is unable to pay the bills, only in those cases will the court be able to appreciate the absence of coercion.

It is a company which is responsible for marketing a finished product. They are responsible for purchasing energy and billing its consumers using distribution networks.

Light distributors remain regulated by the State, and are responsible for the maintenance and monitoring of the different areas of the country.

Red Eléctrica de España (REE) is in charge of transporting energy in High Voltage and managing, maintaining and repairing the necessary infrastructures for this.

Are those companies designated by the Government with which you can apply for the Social Bond of light. They have the obligation to offer this rate by obligation.

These marketers must meet a series of requirements established by the Ministry of Industry, Energy and Tourism to contract in the form of Voluntary Price for Small Consumers (PVPC), the Fixed Price and the Social Bonus.

The Regulated Markets are the reference Marketers which are controlled and managed by the Government in order to protect the most vulnerable consumers.

Unlike the Free Market, where each Marketer is free to set different rates, offers and extra services with prices established by them, always within established scales, being supervised by the CNMC.

Lumisa Energias is located in the Free Market.

It is a discount on the electricity bill, regulated by Royal Decree 897/2017, which specifies the requirements to be entitled to it. Its purpose is to protect homes considered vulnerable. It is a discount applied to the PVPC.

The Voluntary Price for Small Consumers is the price whose price is controlled by the Ministry of Industry within the Regulated Market. It comes to replace the previous Last Resort Rate (TUR). It is applied in the invoices of those consumers with a contracted power not exceeding 10 kW.

It is the Universal Code of the Supply Point. It is a unique code for each energy supply (electric / gas) that identifies it. Start with the sequence ES followed by 20 digits.

The Electrical Installation Certificate (CIE) or Electrical Bulletin is the official document issued by an authorized installer that guarantees that all the requirements to receive the supply are met.

It is Third Party Access to the Network.

It is the cost stipulated by the State that must be paid when contracting a new supply or by increasing the power of an existing supply with an amount of 19,703137 € for each kW hired + VAT.

It is the cost stipulated by the State that must be paid when using the infrastructure of the distribution company in the case of new supplies, when the power contracted increases or if the supply point has not been used for more than 3 years with an amount of 17,374714 € per kW hired + VAT.

It is the cost stipulated by the State that must be paid when using the infrastructure of the distribution company in the case of new supplies, when the power contracted increases or if the supply point has not been used for more than 3 years with an amount of 9.044760 € + VAT.

It is the cost stipulated by the State that must be paid when carrying out the revision of the installation with an amount of 8.011716 € + VAT.

According to what is established in article 79 of Royal Decree 1955/2000, it is the amount to be delivered, at the time of contracting, for an amount equal to the monthly theoretical turnover corresponding to fifty hours of use of the contracted power.

The cadastral reference is the official and mandatory identifier of real estate. It consists of an alphanumeric code that is assigned by the Cadastre so that every property must have a unique cadastral reference that allows it to be placed unequivocally in the cadastral cartography.

It is the physical place where the connection is connected to the distributor's electrical network. That is, the place where the supply is, in your home, office, etc.

Considerations on the concurrency public premises: (According to section 1 of the ITC BT-28 of the REBT-2002) Premises for entertainment and recreational activities: Cinemas, theaters, auditoriums, stadiums, sports halls, bull rings,
hypodromes, amusement parks and fixed fairs, party halls, nightclubs, gambling halls. Meeting rooms, work and health uses.

  • Whatever your occupation: Temples, museums, conference and congress halls, casinos, hotels, bars, cafes, restaurants or similar, common areas in groups of commercial establishments, airports, passenger stations, closed parking lots and covered by more than 5 vehicles, hospitals, clinics, sanatoriums, asylums and nurseries.

Legislation regarding the modalities of electricity supply with self-consumption and production with self-consumption:

  • Real Decreto 900/2015, de 9 de octubre, por el que se regulan las condiciones administrativas, técnicas y económicas de las modalidades de suministro de energía eléctrica con autoconsumo y de producción con autoconsumo.
  • Real Decreto 244/2019, de 5 de abril, por el que se regulan las condiciones administrativas, técnicas y económicas del autoconsumo de energía eléctrica.

Photovoltaic solar energy is a renewable energy source, obtained through solar panels that capture solar radiation and transform it into electrical energy. Therefore, the personal consumption of photovoltaic solar energy "refers to the individual production of electricity for own consumption through photovoltaic solar panels."

Advantages of photovoltaic solar energy self-consumption:

  • Free energy
  • Economic savings, tax free
  • Clean and renewable energy, prevents the emission of tons of CO2 and other pollutants
  • Tax benefit (subsidies, IBI reductions, possibility of deduction of personal income tax ...)
  • Any self-consumption installation makes the house or building have a greater market value

As established in article 9 of Law 24/2013, of December 26, on the Electricity Sector, and again contained in article 4 of Royal Decree 244/2019, of April 5, two types of self-consumption are distinguished:

Without surpluses

When it is a consumer who had a generation facility, destined for their own consumption, connected inside the network of their supply point and that was not registered in the corresponding register as a production facility. In this case there will be a single subject, which will be the consumer subject. In these modalities, an anti-aging mechanism that prevents the injection of excess energy into the transport or distribution network must be installed.

With surpluses

In the case of a consumer associated with a production facility duly registered in the administrative register of electrical energy production facilities connected within its network. In this case there will be two subjects, the consumer subject and the producer. In these modalities, the next and associated production facilities for consumption may, in addition to supplying energy for self-consumption, inject excess energy into the transport and distribution networks. In turn, it is divided into two modalities:

  • With surpluses under compensation. Those supplies with self-consumption with surpluses in which the consumer and the producer voluntarily choose to benefit from a surplus compensation mechanism. To belong to this modality it will be necessary that they meet a series of requirements:
    • The primary energy source is of renewable origin.
    • The total power of the associated production facilities does not exceed 100 kW.
    • That the consumer has signed a single supply contract for the associated consumption, and for auxiliary production consumptions with a marketing company, if necessary.
    • The consumer and producer have signed a self-consumption surplus compensation contract.
    • The production facility does not have an additional or specific remuneration regime granted
  • With surpluses not receiving compensation. Those cases of self-consumption with surpluses that do not meet any of the requirements to belong to the modality with surpluses under compensation or who voluntarily choose not to qualify for said modality. In addition, in this modality, the energy that is not self-consumed instantly is injected into the grid and sold by obtaining the price of the electricity market.

Additionally, the law establishes another classification of self-consumption: 

Individual self-consumption is that by which a single consumer feeds on an electric energy from generation facilities.

Collective self-consumption is that by means of which a group of several consumers who feed themselves, in an agreed way, of electrical energy that comes from community production facilities. In this case, all participating consumers who are associated with the same generation facility must belong to the same type of self-consumption and communicate individually the same agreement signed by all participants that includes the distribution criteria.

Yes, the surplus energy can be sold, according to the provisions of Royal Decree 244/2019, of April 5. The requirement for its sale is that it must be under the mode of supply with self-consumption with surpluses not under compensation and the same standards as any electric power production plant will apply.

In the mode of supply with self-consumption with surpluses, the producer may sell the surplus energy or benefit from the simplified compensation mechanism.

The simplified compensation mechanism is designed for small renewable consumers of up to 100 kW and can compensate in their bill the energy consumed through the network with the excess energy they have not consumed. It will consist of a balance in economic terms of the energy consumed in the billing period, which:

1. If you have a contract with a free marketer the hourly energy consumed from the network and the surplus will be valued at the agreed hourly price between the parties.

2. If you have a voluntary supply contract for the small consumer with a reference marketer:

  • The hourly energy consumed from the network will be valued at the hourly energy cost of the voluntary price for the small consumer in each hour.
  • The excess hourly energy will be valued at the average hourly price.

Example. Allocation criteria and surplus compensation mechanisms:

(1): Completely free and tax-free.

(2): Same price and taxes as the energy used in a normal rate.

*The energy compensation mechanism reduces the electricity bill by deducting from the monthly consumption the economic amount corresponding to the energy surpluses injected into the grid.

*Electricity Tax and VAT: VAT will be applied on the sum of the different prices discounting the compensation.

Those who:

  • Are associated to production facilities whose power does not exceed 100 kW.
  • The generation is of renewable origin.
  • Production plants do not have an additional or specific remuneration regime.

This mechanism is not limited to individual self-consumption, but is also applicable to collective self-consumption.

Self-consumption has been significantly cheaper during these years, although the initial investment still seems important, but it must be taken into account that the useful life of the installation is about 25 years and it takes an average of 4 to 10 years to amortize the investment , so investing in a photovoltaic solar installation will generate a very significant accumulated savings in energy.

We recommend contact with an expert installer, for security reasons and installation warranty.

On the other hand, many municipalities offer subsidies and grants for solar panel installations, so that you can reduce the investment between 40% and 50%; IBI reductions of up to 50%; possibility of deduction of personal income tax (IRPF). These are mainly intended for installations in single-family or community homes related to energy efficiency.

The main components of a photovoltaic installation are:

  • Photovoltaic solar panels. They generate direct current power.
  • Solar inverter. Converts DC to AC for use by household appliances.
  • Safety and security features.
  • Solar and photovoltaic battery. A reservoir that stores excess energy from photovoltaic panels for use in hours when the sun is not available. The battery is not essential for photovoltaic installation.
  • Regulator. Device that adjusts the charging voltage of the batteries, avoiding overloads and overheating. If there is no battery in the installation, no regulator is needed.

The solar panels are compost of modules and the modules of photovoltaic cells that are made of semiconductor materials that transform the solar energy into direct current energy, through the photovoltaic effect. The more energy we need, the greater the surface area of panels we will install.

The energy obtained from the panels will pass through a solar inverter, where it will be transformed into alternating current so that it can be used by household appliances.

All or part of the energy will be used for self-consumption, however, the surplus energy can be used in various ways: storing this energy in batteries, discharge it into the electricity grid to obtain compensation or not using it by disposing of it through an anti-discharge system.

No. On October 5, 2018, this tax was repealed.

Yes, they do. However, energy production is reduced by around 10-25% of a sunny day, but it may vary depending on the thickness of the clouds and the installation itself.

No, they don't. Photovoltaic solar panels need light (preferably sunlight) to generate energy.

However, the excess energy produced during the day can be stored in a solar battery and used when the sun is not available.

Subsidies on state taxes

Many municipalities offer subsidies and grants, so it is advisable to consult the website of each municipality. These subsidies are generally applied to state taxes through discounts on the IBI (Property Tax; between 30% to 50% for 3 or 5 years) or the ICIO (Construction, Facilities and Works Tax; between 30% to 90%).

Subsidies on installation price

Some autonomous communities are aware of the importance of a responsible and sustainable energy model, so there are also subsidies for solar panels to encourage the use of renewable energy and various aspects of self-consumption. These subsidies are on the price of the installation, which are applied as a percentage of the total price of the installation and they are issued from time to time depending on the management of the budgets of each community and they have a specific duration.

Income tax deduction

The taxpayers in the investment in self-consumption installations of electric energy may deduct 20% of the amount of the quantity invested in installations carried out in the habitual residence and in collective facilities of the building destined to any of the following purposes:

  • Installations for self-consumption of electricity, as established in article 9.1.a of Law 24/2013, of December 16, on the Electricity Sector, and its development regulations (modality of supply of electric energy with self-consumption).
  • Installations for the production of thermal energy from solar, biomass or geothermal energy for the generation of hot water, heating and/or air-conditioning.
  • Installations for the production of electrical energy from photovoltaic and/or wind energy, for the electrification of dwellings isolated from the distribution electricity grid and whose connection to it is technically, environmentally and/or economically unviable.

Those facilities that are mandatory are not entitled to the application of this deduction.

Royal Decree 244/2019 of 5 April, which regulates self-consumption, provides for the existence of coefficients to distribute energy in collective self-consumption. The value of these partition coefficients depends on the agreement between the participants, with the only requirement that they must be constant values. These criteria and coefficients should be laid down in the agreement between the parties and each consumer should pass them on to the distributor either directly or through his supply company.

Royal Decree 244/2019 of 5 April, establishes that "The value of these coefficients may be determined on the basis of the billing power of each participating associate consumer, the economic contribution of each consumer to the generation installation, or any other criteria provided that there is an agreement signed by all participants and provided that the sum of these coefficients βi of all consumers participating in collective consumption is the unit. In any case, the value of these coefficients must be constant."

As a last resort solution, and if the participants do not submit different values, the standard provides for partition coefficients calculated on the basis of the maximum powers contracted by the participating consumers. RD 244/2019 of 5 April in Annex I describes a possible energy distribution criterion which can serve as a basis for the implementation of the allocation agreement.

βi : It is the coefficient of distribution of the energy generated among the consumers who participate in the collective self-consumption. This coefficient shall be based on the value shown in an agreement signed by all consumers participating in the collective self-consumption, in addition to being included in the acta of the Meeting of Proprietors, it must be send individually by each associated consumer to the distribution company as responsible of consumption reading. However, the coefficient shall take the value of 1 where there is only one consumer associated with a nearby installation through the network. In any case, these coefficients must have fixed values for all hours of a billing period. In the absence of notification of the distribution coefficients to the person in charge of reading the consumptions, these coefficients will be calculated in accordance with the following formulation:

βi = Pci / ∑Pcj


Pci : Maximum power contracted to the associated consumer i.

∑Pcj : Sum of the maximum powers contracted by all consumers participating in the collective consumption.

Keep in mind that:

  • All associated consumers must belong to the same type of self-consumption.
  • A distribution agreement must be drawn up setting out the criteria for allocating the energy generated.

Consumers under any type of self-consumption can change from any other modality, adapting their facilities and complying with the regulations.

However, it should be noted that:

  • In the case of collective self-consumption, this change must be carried out simultaneously by ALL consumers associated with the same generation facility.
  • Under no circumstances may a consumer be associated simultaneously with more than one mode of self-consumption.
  • The period of stay in the chosen mode of self-consumption shall be at least one year from the date of registration or modification of the contract.
  • Holder: Facility owner (natural or legal person).
  • Representative company ERIDE: Legal person to which the holder delegates, where appropriate, to carry out the procedures relating to the registration of specific remuneration system on his behalf. It is not mandatory for facilities to have an ERIDE's representative company. Additionally, this representative company may also be different from the representative who takes the steps before the CNMC for the purpose of liquidating the specific remuneration system.
  • User representative: Natural person who has been granted sufficient permits to carry out the procedures relating to the rregistration of specific remuneration system on behalf of the holder (either directly or through a representative company). They can be authenticated through an electronic certificate of a natural person or legal person. It is mandatory that the facilities have a representative user, who will be the only natural person who will be able to access the notifications by electronic certificate. The holder can, in turn, be a representative user, as explained below. The holders have, by default, reading access to the specific remuneration system register. The holder, if he so wishes, can become a representative user and thus carry out the procedures related to such registration. To do this, it would be enough for the holder to submit any application. When the owner submits an application, the owner becomes a user representative of the installation, being from this moment the only one that can access all the notifications related to the installation (both those related to the request submitted, and those that could be processed).

The CAU or Self-Consumption Code uniquely identifies self-consumption. It is requested by the authorized installation company to the distribution company and relates to all consumers and all the near generation facilities associated with self-consumption.

For installations in self-consumption supply mode exempt from obtaining access and connection permits, prior to submitting the data in the registry of the different Autonomous Communities, the installer or the holder shall request CAU code from the Distributor. For the rest of the facilities, CAU code will be provided in the application process for the access and connection permit.

The CIL identifier code is the Production Installation Code for settlement purposes (Spanish: Código de Instalación de producción a efectos de Liquidación). It is the code determined by the person responsible for reading that will uniquely identify a retributive unit of an installation. It shall consist of the Universal Supply Point Code (CUPS) followed by a 3-digit numerical field corresponding to each retributive unit of the installation, starting with the value '001' for the first and so on. For these purposes, CUPS will be common to all the retributive units that an installation may contain. In order to correctly apply the specific remuneration system to an installation, each of its remuneration units must have its own CIL code assigned, wich is different from the other remuneration units in the same installation.

The person in charge of assigning the CIL is the person in charge of reading (distribution company or Red Eléctrica de España as appropriate), so you can go to this person to request it.

The common requirements for applications for subsidies for self-consumption are:

  • Have the detailed budget of the installation.
  • Generally subsidies are not cumulative, so you only have to choose one.
  • The applicant must be the owner of the installation or the installation company with the prior authorization of the owner.
  • Only one photovoltaic installation may be subsidized per dwelling.

The requirements for deduction of personal income tax are:

  • The concept of usual dwelling, for the purposes of applying this deduction, is the content in the state regulations governing personal income tax.
  • The installations must be carried out in the usual dwelling of which the taxpayers own, or in the building in which it is located.
  • In the case of housing units in a horizontal property regime in which these facilities are carried out in a shared manner, provided that they have legal coverage, this deduction may be applied by each of the owners individually according to the participation coefficient that corresponds to him, as long as they meet the rest of the established requirements.
  • The deduction will require prior recognition by the Autonomous Administration.
  • The actions to be deducted must be carried out by installation companies which meet the requirements laid down in the regulations.
  • The basis for this deduction is the amounts actually paid in the financial year by the taxpayer.

Yes, the location of the dwelling and the orientation of the solar panels are essential to maximize the performance of the solar self-consumption installation.

It must be taken into account that photovoltaic solar panels are more productive the more solar radiation they can capture. In general, it is recommended to place them facing south, since the panels generate more electricity if the sun’s rays hit the panel perpendicularly. If we want to obtain energy from the panels throughout the year we will place them with a similar inclination to the latitude, however, we must consider that the sun varies its height throughout the year.

Yes, we recommend staying connected to the electricity grid, since the customer can be left without power for any inconvenience or, if no battery is installed, in the hours without sun. Another advantage of remaining connected to the grid is the option of injecting surplus energy into the grid and being compensated for it in the electricity invoice, with the modality of simplified compensation of surplus energy.

Many times with rainwater is enough to clean the solar panels. However, at least once a year, a physical inspection of the panels should be carried out looking for dirt, debris or bird droppings or to see if the electricity production falls. If so, the panels must be cleaned.

You can do the cleaning by hiring a professional or by doing it yourself.

When you remove dirt during the cleaning of solar panels, be careful not to scratch or break the glass, either using tools or stepping on them. It is also important not to use abrasive soaps or abrasive liquids because they could damage the surface of the panel. However, before starting, we recommend you to consult the solar panel instructions and / or consulting your supplier.

The Rush is the part of the installation that links the distribution network and the general protection box for low voltage supplies.

As for its construction they can be underground or aerial, depending on the type of distribution.

When a new supply requires a connection to the distribution network, or an existing supply wants to expand the available power in a supply, it is necessary to make a supply request to the corresponding Distributor.

Through Lumisa, we can help you process this process with the Distributor. You just have to authorize us as your representative to be able to manage everything on your behalf.

The Rush management procedure is:

1. Application phase. This is the opening phase of the file. You must provide us with a series of data and documentation such as:

  • Applicant (Name, ID or CIF, correspondence address, email and telephone)
  • Address for which the supply is requested.
  • Useful surface.
  • Location map and location map of the general protection box.
  • Requested power (kW), which can be determined once the situation map is sent.

The file will be paralyzed until the plans requested by the Distributor are received.

2. Report preparation phase. Once the Lumisa service record has been opened, the Distributor's Technical Department will carry out the study of the affected area, assessing the activities necessary to carry out the requested facilities.

In the same way, they will execute a report with the technical-economic conditions, thus informing the applicant.

3. Project development phase. Once the applicant has accepted the budget prepared by the Distributor, as well as reviewed the required documentation, they are prepared to prepare the necessary actions for the start of the works. In this phase, the CUPS (Universal Supply Point Code) number is assigned, which should be noted.

In the event that official permits and licenses are necessary, such as the works license, the requested file must be kept pending the granting of the same.

4. Work execution phase. Once the necessary permits and licenses have been granted, the work begins and ends, prepared for the hiring of the registration of the supply point.

5. Final hiring phase. Finally, the Certificate of Electrical Installation (CIE) made by a qualified technician must be provided and it is already possible to register the Supply Point with us.

For the preparation of the budgets corresponding to new supplies, and according to article 103 of Royal Decree 1955/2000, of December 1, which regulates the activities of transport, distribution, marketing, supply and procedures for authorization of facilities for Electricity, the deadlines to receive the Distribudiora response of the technical and economic conditions to meet the requested supply are as follows:

1. Low voltage supplies.

  • When a supply of up to 15 kW is requested in which it is not necessary to carry out extension installations, the distribution company will give the technical-economic conditions in writing within five days.
  • For any service when the transformation center installation is not necessary: ??ten days.
  • When the installation of transformation centers is necessary:
  1. 1st auxiliary works service: ten days.
  2. 2. Definitive service with medium to low voltage transformation center: twenty days.
  3. 3rd definitive service with high and medium voltage transformer substation: thirty days.

2. High voltage supplies.

  • For a consumer with a nominal supply voltage equal to or less than 66 kV: forty days.
  • Other high voltage supplies: sixty days.

The technical-economic budgets have a validity period of three months, from the date of communication of said budget.

For new network supplies necessary to meet new supplies or expansion of existing ones of up to 100 kW at low voltage and 250 kW at high voltage that already has the endowments and services required by urban planning legislation, its construction corresponds to the company distributor, the customer must pay the extension scale (€ 17.37 / kW) established by regulation.

For the rest of the cases, the applicant must assume the total cost of the necessary work, such as network extension and those reinforcements and adjustments are met with the criteria of the Ministerial Order IET 26660/015.

As for the cost, when a customer requests the installation of the connection, the Distributor will propose a budget that will depend on the particular case.

That is why, the price may vary depending on the location of the new supply, the condition of the land and other factors that may hinder the electrical installation. If the client or end user hires a higher power or expands the power already contracted, it will also pay the excess for the extension and access rights corresponding to the power increase

Once the installation of the connection has been completed, the client will also have to pay the rights caused by the registration of the supply point.

For the execution of the necessary facilities for new supplies, and according to article 103 of Royal Decree 1955/2000, of December 1, which regulates the activities of transport, distribution, marketing, supply and procedures for authorization of facilities For electric power, the execution deadlines for the commissioning of the installation from the moment the connection rights are met will be the following, counted in working days:

1. Low voltage supplies:

  • When it is not necessary to carry out any extension of the low voltage network: five days.
  • When you only need to expand the low voltage network: thirty days.
  • When a transformation center needs to be built: sixty days.
  • When several transformation centers need to be built: eighty days.

2. High voltage supplies:

  • Connected to a single consumer with a nominal supply voltage equal to or less than 66 kV: eighty days.
  • Other high voltage supplies: the term will be determined in each case depending on the importance of the work to be performed.

Charging points are the instruments that allow us to recharge electric vehicles, and can be installed in private garages, community garages or a community of neighbors, or even in a company car park.

If you have a garage in a single-family home or a flat you own, you can install the charging point for your electric car in it. The installer can take the wiring from the meter to the location of the charging point.

The first thing you should do is request your charging point through our web form. Once requested, our advisers will contact you and we will send you a personalized quote.

No problem, the charging point uses the electricity from the individual meter and we will bill all the energy, both for the home and the electric vehicle, to the owner of the electricity supply.

Yes, the solution would be to register a new electricity supply point only for that charging point. Another option would be to agree with the community of neighbors by connecting the charging point to a common electrical supply and reaching an agreement with the community of neighbors.

According to the regulations, the communication of said installation is necessary, however, its approval by the same is not necessary.

Ideally, depending on the electrical appliances you have, it would be a power of 4.6 KW, and with a power control device installed in the charging point it would be sufficient.

The charging time of an electric vehicle depends on several factors related to the vehicle and the type of charger. Next, we show you an indicative table with the charging times of a charging point.
