MTerra Solar has completed grid synchronization for Phase 1 of its 3.5 gigawatt solar-plus-storage project in Luzon, Philippines, with energization reported in February 2026. The milestone enables initial power exports to the Luzon grid and marks a major step in scaling utility-scale renewable integration in Southeast Asia.
Key Facts At A Glance
- Phase 1 of the 3.5 GW MTerra Solar project has completed grid synchronization
- Project includes integrated solar generation and battery energy storage
- Located in Luzon, Philippines
- Energization completed in February 2026
- Power exports to the grid are expected as early as March 2026
- Project is described as the world’s largest integrated solar and battery facility
MTerra Solar has energized and synchronized the first phase of its 3.5 gigawatt solar-plus-storage development with the Luzon transmission network, according to reports published in February 2026. The project is being positioned as the world’s largest integrated solar and battery energy storage facility once fully completed.
The initial grid connection allows the project to begin exporting electricity to the Luzon grid, with commercial power delivery expected as early as March 2026. The development combines large-scale photovoltaic generation with battery energy storage systems designed to provide firm and dispatchable renewable power.
The Philippines has been accelerating renewable energy deployment to reduce reliance on imported fossil fuels and strengthen grid stability. Large hybrid projects such as MTerra Solar are intended to help address intermittency challenges by pairing solar output with battery storage capable of shifting supply to periods of peak demand.
Once fully operational, the 3.5 GW facility is expected to significantly increase renewable capacity in the country’s main power grid, which serves Luzon, the nation’s largest demand center. The scale of the project places it among the most ambitious solar-plus-storage initiatives globally.
