Philippines Government Moves Quickly for 'World's Largest' Solar and Storage project with 4.5GWh BESS
The Board of Investments (BOI) in the Philippines has given a ‘green lane certificate’ to make the procedure faster for a solar and storage project said to be the largest in the world.
Terra Solar project will continue the plan to pair 3,500MW of solar PV with a 4,500MWh battery energy storage system (BESS) with the given certificate by BOI.
Terra Solar would span 3,500 hectares of land in the Bulacan and Nueva Ecija provinces and would cost PHP185 billion (US$3.2 billion). The project would be the largest in the world by capacity, in terms of solar, BESS and both technologies combined.
the BOI, which is the Philippines government’s lead industry development and investment promotion agency and a green lane certificate is designed to speed up the process of acquiring permits and licenses for strategic investments.
It is hoped the certificate could help Terra Solar reach commercial operations for its first phase for which the size has not been disclosed by February 2026 and the second phase the year after. To align with the country’s national development plans
The project has also received a Certificate of Energy Project of National Significance from the Department of Energy, more of a formality as any project above US$59 million in investment value receives this certificate automatically.
The BOI’s green lane certificate for Terra Solar coincided with many other renewable investment approvals from the department, including PHP263 million worth of solar rooftop projects, the PHP297 billion Pakil Pumped Storage Hydroelectric Power Project and the PHP114.7 billion Guimaras Strait Offshore Wind Power Projects.
Emmanuel Rubio, president and CEO of Meralco subsidiary MGen received the green lane certificate. The project is being developed by Terra Solar Philippines, Inc. (TSPI), which is co-owned by independent power producer (IPP) SP New Energy Corporation (SPNEC) and utility Manila Electric Company (Meralco).
