Terra Solar Philippines Inc. (TSPI), a subsidiary of MGEN Renewable Energy Inc. (MGreen), has signed a Battery Energy Storage Systems (BESS) Supply Agreement with Singapore-based Huawei International Pte. Ltd.

The deal involves delivering advanced BESS technology for the MTerra Solar project, a facility poised to become the largest integrated solar photovoltaic (PV) and battery storage system in the world.

Huawei’s contribution to the MTerra Solar project includes the full 4,500 megawatt-hours capacity of its battery energy storage system.

This agreement also marks Huawei’s largest BESS project to date for an integrated solar and storage facility.

Huawei’s advanced technology for MTerra Solar includes containerized batteries and auxiliary components like fire suppression systems, battery management systems, and energy management systems.

The system also features a two-stage DC/DC and DC/AC architecture to ensure constant active power output, even under high-voltage ride-through conditions.

These innovations will allow MTerra Solar to store excess energy generated during low-demand periods and supply it back to the grid during peak demand, ensuring energy reliability and resilience.

“By combining MTerra Solar’s vast solar power generation capacity with Huawei’s cutting-edge energy storage solutions, we are creating a powerful synergy that will optimize grid operations, ensuring a consistent and uninterrupted power supply,” Emmanuel V. Rubio, president and CEO of Meralco PowerGen Corporation, said.

The MTerra Solar project will integrate 3,500 megawatts peak of solar PV and 4,500 MWh of battery storage, supplying clean energy to over two million households.

Spanning Central Luzon, the project recently broke ground in Nueva Ecija and is set to begin operations in phases, with the first phase scheduled for February 2026 and the second in February 2027.

Huawei brings its global expertise in large-scale renewable energy projects to the Philippines, having previously developed the Red Sea New City solar storage microgrid in Saudi Arabia.

That project, which spans 100 kilometers of grid infrastructure and operates entirely on solar and battery storage, delivered over 1 terawatt-hour of green electricity in its first year.
