Electricity bills will decrease by 4.7% for households in 2026, according to calculations by the Spanish government.
The decrease in the bill for companies will range from 4.5% to 10%.
BarcelonaThe Spanish government estimates that the electricity bill for an average Spanish household will fall by 4.7% in 2026 due to the reduction in energy prices thanks to the boost from renewables, even though the costs of the electricity system will increase by 15% and tolls by 4% during the next year. According to funds from the Ministry for Ecological Transition and the Demographic Challenge, the decrease in electricity bills will reach 8.55 percent for industry, 9.91 percent for energy-intensive industries, and 4.95 percent for SMEs, meaning the overall decrease will range between 4.5 and 1 percent. The Ministry has opened for public comment the draft order establishing the electricity system charges for 2026. This consultation reveals that electricity system costs will amount to €4,057.4 million, 15% higher than in 2025 (€8,510.4 million), while revenues to offset these charges will amount to €4,453 million, derived from taxes on carbon dioxide (CO2) emission allowance auctions.2and specific taxes.
The calculations for the Ministry of Ecological Transition are based on a forecast of higher contracted power and energy consumption compared to the current year, in line with the electrification of the economy, as shown in the project's explanatory memorandum. These charges, along with the tolls set by the National Commission on Markets and Competition (CNMC), make up the regulated portion of the electricity bill.
They finance items such as the remuneration of historical renewable energy sources and the amortization of the debt generated between 2000 and 2013 due to the tariff deficit. They also cover the cost of the extra-peninsular systems of the islands and those of Ceuta and Melilla. Now, the economic impact of the emergency measures to be adopted in the Canary Islands to guarantee the security of electricity supply on the islands of Gran Canaria, Tenerife, and Fuerteventura, approved after the mainland blackout of April 28, has also been incorporated.
Thus, the amount of net charges to be financed by consumers in 2026 is €4,057.4 million, around 15% higher than the €3,526.54 million shown in the order's explanatory memorandum for 2025. The majority of the costs correspond to remuneration (Recore), at €5,760 million, and to the annual deficit payments for regulated activities (€1,883.4 million). The charges are financed with specific taxes and part of the revenue from CO2 auctions.2 and with direct payments from consumers through the regulated portion of the monthly bill
