Meralco PowerGen Corporation (MGEN), together with its partners, has inaugurated Phase 1 of the MTerra Solar Project in Nueva Ecija, Philippines. Phase 1 of the project comprises 1,373 MW of solar photovoltaic (PV) capacity and 825 MW/3,300 MWh of battery energy storage system (BESS) capacity. Under Phase 1, more than 2,000 MWdc of solar panels have been installed, while all 741 battery units have been fully energized.
Furthermore, the project currently exports up to 750 MW to the Luzon grid. The project will supply 600 MW of renewable power to Meralco under a power supply agreement following successful grid testing. The project also supports the Philippine Energy Plan and the country’s renewable energy targets of 35 per cent by 2030 and 50 per cent by 2040.
In May 2026, MGEN commissioned the Toledo BESS project in Cebu, Visayas. Phase 1 of the project delivers 25 MW/56.44 MWh of two-hours BESS capacity. The project, developed through Toledo Energy Development Corporation, utilizes lithium-ion technology to store electricity from renewable and conventional sources. Phase 2 of the project, which will add another 25 MW/56.44 MWh, is targeted for completion by June 2027, subject to regulatory approvals.
