Energy calls for the first 650 MW cogeneration auction for February

The State Secretariat for Energy has called for the first auction for the granting of the specific remunerative regime for high-efficiency cogeneration plants, which will be held on February 23, 2027, with ten differentiated products totaling 650 MW. The call is published in the Official State Gazette (Boletín Oficial del Estado) no. 283, of November 13, 2026, Section III, by means of the Resolution of November 5, 2026 (BOE-A-2026-23813), signed by the Secretary of State for Energy, Joan Groizard Payeras.

The auction implements the mandate of Royal Decree 530/2026, of June 24, which establishes the framework for the calls and approves the granting of the specific remunerative regime for 1,200 MW of capacity for high-efficiency cogeneration plants of subgroup a.1.1 and groups b.6 and b.8, according to the classification of article 2.1 of Royal Decree 413/2014, of June 6. This granting must be carried out through successive auctions called by resolution of the holder of the State Secretariat for Energy.

The allocation procedure is governed by Order TED/672/2026, of July 2, which develops the methodology, the settlement mechanism, and the remunerative parameters, and sets the indicative calendar for the 2026-2027 period. The legal authorization for this exceptional regime is found in article 14.7 of Law 24/2013, of December 26, on the Electricity Sector.

Ten products and a quota of 650 megawatts

The call establishes the quotas per reference plant type (ITR), which total 650 MW:

• ITR-0106: 2 MW.
• ITR-0107: 25 MW.
• ITR-0108: 50 MW.
• ITR-0109: 8 MW plus the unawarded portion of the first product.
• ITR-0110: 210 MW plus the unawarded portion of the second product.
• ITR-0111: 130 MW plus the unawarded portion of the third product.
• ITR-0112: 5 MW.
• ITR-0113: 75 MW.
• ITR-0116: 95 MW.
• ITR-0117: 50 MW plus the unawarded portion of the ninth product.

The percentage of quota excess in the settlement process is set at 10% for all products, such that the allocated capacity may not exceed the quota increased by that margin. Additionally, the maximum installed capacity for biomass cogeneration plants of groups b.6 and b.8 is set at 35 MW to be eligible for the remunerative regime.

Calendar: from pre-qualification to February 23

The approved calendar establishes the following milestones:

• Opening of the prequalification and qualification period: business day following publication, November 16, 2026.
• Closing of the documentation period: February 15, 2027, at 13:00.
• Closing of the error correction period: February 18, 2027, at 13:00.
• Auction rehearsal with qualified participants: February 19, 2027, at 13:00.
• System access and electronic signature test: February 22, 2027, at 9:00.
• Holding of the auction: February 23, 2027, with bid reception from 9:00 to 11:00, allocation and provisional results before 16:00, two hours for claims, and a maximum of 24 hours for validation.

Guarantees, tranches, and execution deadlines

OMI-Polo Español SA (OMIE), through its subsidiary OMEL Diversificación, SAU, acts as the managing entity, while the National Commission on Markets and Competition serves as the supervisory entity. Participants must establish guarantees of 20 euros/kW based on their maximum qualification volume, in the name of OMEL Diversificación, SAU.

Divisible and indivisible tranches may be bid, up to a maximum of 20 tranches per bid, with maximum sizes ranging from 1 MW for the first, fourth, and seventh products to 100 MW for the sixth. The maximum period to meet the registration requirements in operational status will be 60 months for new installations linked to ITR-0106, ITR-0107, ITR-0108, and ITR-0116 and for modifications to ITR-0117, and 48 months for the rest. The resolution takes effect from the day following its publication and is subject to contentious-administrative appeal before the Audiencia Nacional within two months and, optionally, a request for reversal before the Secretary of State within one month.

The result of this first call will set the pace for the deployment of the planned 1,200 MW and conditions the investment of industrial operators running high-efficiency cogeneration plants, who face the event with a partial quota and a competitive downward mechanism on the initial investment.
