The project will occupy 226.47 hectares and connect to existing CFE infrastructure through a 34/115 kV step-up substation and an approximately 1 km, 115 kV transmission line.

BESS becoming standard

Taken together, the 20 projects identified by pv magazine Mexico over the past month represent more than 3 GW of planned solar capacity, highlighting a substantial new wave of utility-scale PV development across the country. The pipeline stretches across 10 Mexican states and includes projects ranging from around 42 MW to more than 370 MW, with several developments exceeding 200 MW.

Battery storage is a defining feature of this new project pipeline: most of the proposed plants include a BESS, and several specify three-hour storage configurations, including La Morita III, Malva Solar, Santos, Ficus Solar, Barajas Solar and El Gorrión. The filings and approvals also point to particularly strong development activity in Nuevo León, Veracruz, Coahuila and central Mexico, while the combination of PV and storage suggests that batteries are becoming an increasingly standard component of new large-scale solar projects seeking development and environmental approval in Mexico.
