The Ministry for Ecological Transition and the Demographic Challenge (MITECO) has launched a public consultation on the proposed order that will update the remuneration parameters for renewable energy, cogeneration, and waste-to-energy facilities for the period 2026–2031. This text will determine how much and how electricity production will be remunerated under the specific remuneration scheme for the next six years.

The proposal, open for comments until November 24, redefines profitability values, standard costs, and revenue estimates for more than 60 types of facilities. It does not modify the initial investment or the regulatory useful life, but it does modify the calculations that determine the return on investment and operation.

The consultation comes at a sensitive time: after five years of volatile wholesale prices and partial revisions, the new framework seeks to stabilize the remuneration of more than 65 GW of power covered by the specific regime.

Companies analyzing the text will be able to see how their regulated profitability will evolve compared to 2020–2025 and submit observations on costs, price assumptions, and production factors. The provisions of this order will determine the economics of existing plants and the pace of new investments throughout the next decade.

For the sector, the document will establish profitability—which in the previous cycle was 7.39% real before taxes—and update market and CO₂ prices that will serve as a benchmark for future payments. A change of just a few tenths of a percent in the WACC can significantly alter the regulated revenues of the plants and the attractiveness of future investments.

The text also includes a correction to the annexes with new standard installations and revised parameters for photovoltaics, wind power, biomass, biogas, cogeneration, and waste treatment. Each company should check whether its assets are listed in the correct table, as the allocation affects the level of remuneration. In particular, plants with fuel-related costs—gas or biomass—will continue to have their operating remuneration updated annually according to the methodology of Order TED/526/2024.

The order will apply from January 1, 2026, and must be approved before February 28 of that year. The deadline for submitting objections is just ten business days, and responses must be sent by email to [email protected] , with the subject line “Objections Order period 2026–2031”.
