This groundbreaking partnership includes the deployment of Huawei’s advanced Battery Energy Storage Systems (BESS) to manage the facility’s massive 4,500 megawatt-hour capacity.
“To date, this is Huawei’s biggest BESS project for an integrated solar photovoltaic and BESS facility,” according to MGEN Renewable Energy Inc., owned by Meralco.
“This collaboration reinforces the Philippines’ potential to be a global leader in renewable energy innovation, with MTerra Solar set to become the world’s largest integrated solar PV and battery storage facility,” it added.
Big picture
Located in Central Luzon, the MTerra Solar project will pair 3,500 megawatts of solar power with 4,500 megawatt-hours of battery storage, providing clean energy to over two million homes.
Construction has started in Nueva Ecija, marking a major step forward for this landmark project.
It will begin operating in phases, with the first phase set to launch in Feb. 2026 and the second phase following in Feb. 2027.
Management’s view
“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,” said Emmanuel V. Rubio, MGEN president and CEO.
“This capability not only enhances grid stability but also enables the seamless integration of variable renewable energy into the national energy grid,” said Dennis B. Jordan, President and CEO of MGreen.
Next-generation energy solutions
Huawei’s advanced energy solutions, showcased in projects like Saudi Arabia’s Red Sea solar microgrid, are set to play a key role in MTerra Solar in the Philippines.
These systems will enable MTerra to efficiently store energy during low demand and stabilize grid supply during peak periods.
Advanced safety features and rigorous testing will ensure reliability, positioning MTerra Solar as a future benchmark for large-scale renewable energy projects.
