Mexico’s Ministry of Environment and Natural Resources (SEMARNAT) has published new energy project submittals and approvals in Ecological Gazette 0047/26, highlighting ongoing private investment alongside public baseload expansion. The filings reflect active developer efforts to advance utility-scale solar, wind, and battery energy storage system (BESS) capacity—led by Fresnillo, Atlantica Renewable Power, Solarig, and Firme Beta—while state utility CFE progresses its 477.296 MW CCC Guadalajara project. These regulatory milestones signal continued private-sector reliance on federal environmental permitting (PEIA) to strengthen grid reliability and expand regional generation capacity within Mexico’s evolving energy framework.

SEMARNAT, through its Environmental Impact and Risk Directorate (DGIRA), has published official records detailing the latest filings and approvals for utility-scale renewable energy developments across Mexico. The submittals reflect ongoing private investment in solar photovoltaic and wind infrastructure aimed at expanding regional clean energy capacity.
Leading the new entries under the Environmental Impact Assessment Procedure (PEIA) submittals section, Fresnillo Solar PV submitted a regional environmental impact Assessment (MIA-R) for the Fresnillo PV Atocha solar facility located in Zacatecas. The project features an installed peak capacity of 120.846MW and a nominal output of 100MWac,through 164,416 solar panels, 360 inverters, and 18 transformation centers across 306.68ha. The complex integrates a 120MVA step-up substation alongside a 30 MW/112.5 MWh Battery Energy Storage System (BESS) to reinforce grid stability.
 Additional solar activity in the issued resolutions section includes approvals for Solarig Mexico’s 2-year construction and 30-year operational authorization for the PV Moquel Solar project in Campeche, as well as the PV El Guayabo Solar project in Veracruz.
In the wind sector, Atlantica Renewable Power Mexico secured regulatory approval under the issued resolutions section for the Parque Eolico Igu project in Juchitán de Zaragoza, Oaxaca. The regional environmental impact statement grants a 2.5-year construction phase and a 25-year operational lifecycle for the wind farm in the Isthmus of Tehuantepec region.  
CFE Advances Combined-Cycle Capacity in Jalisco
Alongside private renewable filings, state utility CFE submitted a MIA-R for the CCC Guadalajara project in Acatlán de Juárez, Jalisco. The natural gas-fired combined-cycle power plant is projected with a guaranteed net capacity of 477.296 MW (±10%) in combined-cycle mode and 339.667 MW (±10%) in open-cycle mode, with an estimated natural gas consumption of 67.77 MMcf/d. Designed with a net efficiency of 55.46%, the complex features 1 gas turbine, 1 heat recovery steam generator, 1 steam turbine, a dry cooling system, and dual-fuel capability providing 414.669 MW (±10%) in combined-cycle on diesel backup. Occupying 24.823691 ha, the project includes a 400 kV switching substation with 2 incoming and 2 outgoing feeders to support regional grid interconnection.
According to Proyectos México, the tender is structured as an international public bidding process under trade agreements for a turnkey engineering, procurement, and construction (EPC) contract under a financed public works model. Proyectos México lists a required execution timeframe of 1,260 natural days, and a contract expiration target of 2030. The bidding process opened on Sep. 8, 2026, with proposal submissions scheduled for Oct. 12, 2026, and the final award decision expected on Nov. 6, 2026. Additionally, the contract mandates a minimum national content threshold of 19.67% for project components and 90% for site labor.
