Timeline Extended Again for Renewable Energy Projects

Mexico's Energy Ministry (Sener) has postponed the official results of its fast-track renewable energy and electrical storage auction for a second time, now set for September 23, 2026. The adjustment was announced June 8, 2026.

According to Expansión, this marks the second calendar shift. A first delay on May 26 extended the interest registration period through May 29. The June 8 announcement moved results to September 23, with permit notifications following on September 24, roughly one week past the original deadline. Sener attributed the postponement to the need for thorough review and analysis of all submissions while maintaining process transparency. Developers have reported operational challenges in meeting technical requirements.

32 GW Goal Within Reach

The fast-track program, launched in May 2026, forms part of Round 3 of Mexico's binding electricity sector planning framework. Sener aims to deploy up to 32 gigawatts of capacity through multiple calls. Winning projects must combine renewable generation with battery storage systems providing at least 30 percent of total offered capacity. Commercial operation is scheduled between 2027 and mid-2030.

According to Energía a Debate, the bidding coordinates approvals with the National Energy Commission (CNE) and the Federal Electricity Commission's (CFE) grid interconnection verification process.

June and July Milestones

The next critical dates are the National Center for Energy Control's (Cenace) ruling, expected between June 11-19, and the formal permit submission window to the CNE running from June 16 through July 15, 2026. These outcomes will determine how many megawatts join Mexico's national electrical system in the second half of the decade.
