PetroGreen Energy Corporation’s EcoSolar Energy unit has accomplished another step to building a battery energy storage system (BESS) in Capiz after securing an environmental compliance certificate (ECC) from the Department of Environment and Natural Resources. The clearance allows the company to advance development work for the 20 MW facility, which is intended to reinforce the stability of the Panay sub-grid once operational.

The ECC, issued on November 13 by the Environmental Management Bureau Region 6, authorizes EcoSolar Energy Corporation (ESEC) to undertake the environmentally compliant construction of the project on a 0.6-hectare site in Panitan. The approval covers the installation of electro-mechanical equipment, associated civil works, and other components necessary for the BESS plant.

PetroGreen said the ECC builds on a series of pre-development milestones the project has already achieved. These include endorsements from local government units earlier this year, secured in April and June, as well as a system impact study approval granted by the National Grid Corporation of the Philippines in October.

PGEC Assistant Vice President Yrel V. Ventura welcomed the ECC, saying it brings the company closer to its target timeline for constructing and operating the BESS facility by the fourth quarter of 2026. 

“We thank DENR-EMB Region 6 for this ECC approval which follows other pre-development milestones achieved such as the local government units’ endorsements in April and June, 2025 and the system impact study (SIS) approval by the National Grid Corporation of the Philippines in October, 2025,” he said. “All these bring us closer to constructing and operating our Panitan BESS project by 4Q 2026 to support stability of the Panay sub-grid and hence added energy security for Panay communities.”

The company said the project is designed to enhance local energy reliability and contribute to the region’s long-term power security once completed.
