Philippines Unveils USD 4 Billion Terra Solar Project, World’s Largest Solar Storage Facility

The Philippines has officially inaugurated the world’s largest solar storage facility, the Terra Solar Project, spanning 3,500 hectares with a total investment of USD 4 billion. The project is set to deliver a photovoltaic capacity of 3,500 megawatts (MW) alongside a 4,500 megawatt-hour (MWh) battery storage system, powering 2.4 million households and cutting carbon emissions by 4.3 million tons annually.

The announcement was made during the recent opening ceremony led by President Ferdinand Marcos Jr.

President Marcos highlighted the project’s critical role in addressing the country’s growing energy demands and the urgent need for renewable solutions. The Terra Solar Project is designed to address two key challenges: the growing demand for electricity and the urgent need to transition to renewable energy sources,” he stated, reaffirming the government’s commitment to sustainability and reducing reliance on fossil fuels.

Strategically located in Nueva Ecija and Bulacan, the facility will provide 850 MW of solar power to Meralco, the Philippines’ largest electricity distributor, over a 20-year period. The project will be delivered in phases, with the first 600 MW slated for completion in February 2026 and an additional 250 MW in February 2027.

With an annual carbon reduction equivalent to removing 3 million gasoline-powered vehicles from the roads, the Terra Solar Project represents a major milestone in the country’s renewable energy ambitions. The initiative aligns with the government’s target of achieving a 35% renewable energy mix by 2030 and 50% by 2040, building on a strong foundation of nearly 30% renewable energy contribution by the end of 2023.

The Terra Solar Project reflects the Philippines’ growing leadership in clean energy innovation and infrastructure, positioning the nation as a key player in the global transition towards a sustainable, low-carbon future.
