          Prices with taxes include the Special Electricity Tax (IEE) of 5.11% and Value Added Tax (VAT), which will be 21% starting January 1, 2025, according to Royal Decree-Law 8/2023, of December 27. New regulated costs that will apply from January 1, 2025, are specified in Order TED/1487/2024, of December 26, which sets the prices for the electricity system charges and various regulated costs for the electricity system for 2025, approved by the Ministry for Ecological Transition and the Demographic Challenge, and in Resolution RAP/DE/009/24, which establishes the access tolls for the transport and distribution networks for 2025 issued by the National Commission for Markets and Competition (CNMC).

          The monthly rental price of the electricity meter will be set by the Ministry of Industry, Energy, and Tourism for the corresponding access rate and charged by the Distribution Company, including VAT and indicated on the invoices issued by LUMISA.

          These prices include the regulated cost associated with the financing mechanism of the Social Bonus, according to Order TED/1487/2024, December 26, for financing the Social Bonus: Fixed cost per customer (commercialization) of 0.0127424301 euros/day.

          The energy price term is calculated following Circular 3/2020 of the National Commission for Markets and Competition and Royal Decree 148/2021, which sets the calculation methodology for the electricity system charges. The indexed price is calculated with the following formula:

          Indexed Price = [(OMIE + ADJUSTMENTS + RO + CO) x (1 + PR(%)) + FNEE + BS] x (1 + CD(%)) + ATR, which includes the following components:

          • OMIE: Average price of the Spanish daily electricity market
          • RO: Payments to system operators (REE) and market operators (OMIE)
          • PR(%): Losses in transmission and distribution networks
          • BS: Contribution to the Social Bonus
          • ATR: Access tolls
          • ADJUSTMENTS: Includes adjustment costs, interruptibility, capacity payments, and other concepts of the supplied energy
          • CO: Operational cost of Commercialization
          • FNEE: National Energy Efficiency Fund
          • CD(%): Deviation cost

          Additionally, Lumisa will charge a monthly amount of €3.90 (€4.72 including VAT) per supply point for management costs.

          Variations in taxes and regulated concepts (upward or downward) will be passed on to the customer as appropriate. Likewise, any new regulated concept, rate, or tax created during the term of the contract may be passed on to the price.

          Offer for new electricity contracts with 2.0TD access tariff, intended for supplies with contracted power equal to or less than 15 kW and without Social Bonus. The conditions will remain active for 12 months from the start date of the contract. No permanence commitment.

          The energy price under this tariff is updated daily based on the electricity market, and calculated using the official formula established by Circular 3/2020 of the CNMC and Royal Decree 148/2021 (Indexed Price = [(OMIE + ADJUSTMENTS + RO + CO) × (1 + PR(%)) + FNEE + BS] × (1 + CD(%)) + ATR). In addition, a management fee of €3.90/month (€4.72 VAT included) per supply point is applied.

          Frequently asked questions

          The indexed rate adjusts the price of electricity based on the wholesale energy market. The energy prices are calculated according to Lumisa's pricing formula and are updated monthly based on wholesale market fluctuations. This means that electricity prices vary each hour, depending on supply and demand.

          If you are flexible with your consumption, you can take advantage of the most economical hours and save on your electricity bill.

          The main advantages of signing up for Lumisa's indexed rate are:

          • Access to lower prices during off-peak hours
          • Transparency in costs
          • Potential savings if you adjust your consumption to the most economical hours

          The main risk is uncertainty, as prices can rise during peak hours or due to market fluctuations. However, the impact depends on your consumption.

          You can check today's electricity prices and find the most profitable hours to consume electricity directly on our electricity prices today page or on ESIOS. This way, you can save by taking advantage of the most economical time slots.

          The fixed rate keeps the price per kWh constant throughout the contract, while the indexed rate varies according to electricity market prices. The choice depends on your preference for stability or potential savings.

          Yes, you can change rates once a year, either from a fixed rate to an indexed rate or vice versa. If you're thinking of making the change, contact us via email at [email protected], and we'll help you choose the rate that best suits your needs.
