The Manila Electric Company’s (MERALCO) engineering and operations subsidiary, MERALCO Industrial Engineering Services Corporation (MIESCOR) entered an agreement with Terra Solar Philippines, Inc. (TSPI) to design and build essential infrastructure that will link the solar plant to the grid.

“MIESCOR plays a crucial role in connecting the Terra Solar plant to the grid, and we are excited to be

part of this groundbreaking step in renewable energy. The project, formalized through our contract signing with Terra Solar Philippines, Inc. (TSPI), is already underway,” said MIESCOR President and Chief Executive Officer Richard O. Ochava.

MERALCO said that it would construct 34.5/230/500-kilovolt 

(kV) Main Collector Substation, two 34.5/230-kV Solar PV Satellite Collector Substations, and two double-circuit 230-kV Transmission Lines.

Site operations for the project are already in progress, with the team focused on meeting energization targets. The first phase, with a capacity of 2,500 megawatt peak (MWp), is set for completion by 2026, followed by the second phase in 2027.

TSPI is leading the development of what would be the largest solar facility with battery storage in

the Philippines. The project includes a 3,500 megawatt peak (MWp) solar plant and a 4,500 megawatt-hour (MWh) Battery Energy Storage System (BESS), spanning across Nueva Ecija and Bulacan.

“MIESCOR is fully committed to advancing renewable energy infrastructure. Our goal is to become a leading force in the renewable energy sector and in promoting sustainable development in the Philippines,” Ochava added.
