The Ministry of Ecological Transition is confident that the electricity bill will fall in 2026 by between 4% and 10%, as a result of lower energy prices expected for next year “thanks to competitive renewable energy generation,” and despite increases in the regulated segment proposed by the Sarah Agesen administration and the National Commission for Markets and Competition (CNMC).
The Green Transition forecasts that for ordinary domestic consumers covered by the regulated tariff (PVPC) this reduction will be 4.66%, while for SMEs (tariff 3.0 TD) it will be 4.95%, for industry (tariff 6.xTD), 8.55%, and for condensed electricity, 9.91%.
These calculations are based on charges (the cost of networks) and charges (the fixed part of the bill that rewards, for example, the oldest renewable energy sources), proposed, respectively, by the CNMC and the Ministry, and on the future energy price for next year reflecting the OMIP, which stands at 56.7 euros per MWh as of November 28, while the average for 2025 has so far been 64.96. EUR/MWh.
On the one hand, the ministry proposes to increase net charges for the electricity system by a little more than 10%, while in the case of fees, the CNMC’s proposal expects them to rise next year by about 4%.
Publicizing the Environmental Transition for Public Hearing and Media The draft order establishes electric system fee rates, sets out various regulated costs for the electric system for the year 2026, and approves the distribution of amounts to be financed related to the social bond.
According to the draft order report, the total amount of the costs of the electrical system amounts to 8,510,447 million euros, while the revenues allocated to compensate for these fees amount to about 4,453,023 million euros, coming mainly from the tax figures of Law 15/2012 of December 27, and from auctions of carbon dioxide emission rights, which will leave an amount of net fees to be financed by consumers in 2026 of 4,057,424 million.
In absolute terms, the increase in fees for next year will be 15%, but as demand increases, the percentage decreases to just over 10%, according to sector sources. CNMC expects only a 2.3% increase in demand in its proposal.
Within the fixed part of the electricity bill, charges are a type of electricity system cost that corresponds, essentially, to compensations for historical renewables and surcharges on the islands, Ceuta and Melilla, among others.
In 2026, Recore, that bonus for historic renewables, will be worth $5,760.2 million, and the bonus for non-Peninsula systems will be about $840.95 million.
The fees are funded through specific taxes, with a portion collected from CO2 auctions and through direct payments from consumers through other means. This year, the government will contribute $1,100 million to carbon dioxide auctions, plus another $1,995 million for a 7% tax on electricity generation, as well as $709.34 million from the 2024-2026 surplus, among other items.
