Rigel Solar secures environmental approval for 400 MWp solar-plus-storage project in Michoacán and Jalisco with 160 MW / 640 MWh BESS

Type: Development · Technology: Hybrid · Country: Mexico · Capacity: 400 MWp · Announced: 2026-06-16

Rigel Solar submitted an environmental impact assessment to Mexico’s Secretaría de Medio Ambiente y Recursos Naturales (Semarnat) for a 400 MWp solar photovoltaic project with 160 MW / 640 MWh of battery energy storage (BESS) capacity, located across Michoacán and Jalisco states. The project spans 825.92 hectares with two main sites: Polígono Norte in Marcos Castellanos and Cojumatlán de Régules (Michoacán), and Polígono Sur in Marcos Castellanos, alongside a 7.80 km 400 kV transmission line connecting to CFE’s Subestación Mazamitla in Jalisco. The solar array will use bifacial modules on single-axis trackers, underground medium-voltage collection network, and modular containerized BESS with integrated power control, transformers, cooling, and fire protection systems. The total investment is estimated at 5,477.5 million Mexican pesos (approximately $318 million), with 3% allocated to environmental mitigation measures totaling 164.3 million pesos ($9.5 million).
