Meralco PowerGen Corporation and its partners have inaugurated Phase I of the MTerra Solar project in Nueva Ecija, Philippines, comprising 1.373GW of solar PV and 825MW/3,300MWh of battery storage. Once fully developed, the project will reach 3.5GW of solar PV and 4,500MWh of BESS capacity, making it one of the world’s largest single-site integrated solar-plus-storage projects, according to MGEN. The facility can currently export up to 750MW to the Luzon grid, while all 741 battery units on site have been energized. After grid testing, it is expected to begin supplying power under a 600MW mid-merit PSA with Meralco.
