MTerra Solar Now Delivering Power to the Luzon Grid
The MTerra Solar project is set to become the Philippines’ largest integrated solar PV and battery facility. Once fully completed, it will deliver 3,500 MWp of solar PV capacity paired with 4,500 MWh of BESS.
Pasig City, Philippines – 14 March 2026 – Meralco PowerGen Corporation (MGEN), through its affiliate Terra Solar Philippines Inc. (MTerra Solar), has successfully energized the MTerra Solar project as a generator – marking the moment the facility went live and began delivering electricity to the grid.
The milestone marks the first electron from MTerra Solar sent through to the Luzon grid, signaling that the facility is now live – just 16 months after its groundbreaking. This phase is set to supply up to 85-megawatts (MW) of mid-merit power to the grid, supporting energy demand during peak daytime hours and marking the initial delivery to Meralco.
Following its energization as a generator, the project will continue to ramp up its output in the coming months in close coordination with the National Grid Corporation of the Philippines (NGCP), in line with its System Impact Study (SIS) and operational plan.
“This is a defining moment for MTerra Solar. With the facility now operational, we have started a bigger journey – ramping up generation and steadily delivering capacity that strengthens energy security and advances the Philippines’ self-reliance. This milestone comes at a critical time as we continue to expand the country’s energy capacity,” said MGEN President and CEO Emmanuel V. Rubio.
“MTerra Solar exemplifies Filipino ingenuity and pride – built by Filipinos for the Filipinos. The project is now delivering reliable and clean energy which will power progress for industries and communities. We remain in close coordination with the NGCP to ensure that project is safely integrated into the grid,” said MTerra Solar President & CEO Dennis B. Jordan.
The energization of the project as a generator marks a significant step in strengthening the country’s energy security by adding domestic power capacity and supporting energy independence. Once fully completed, it is expected to generate 3,500 MWp of solar photovoltaic, complemented by a 4,500 MWhr battery energy storage system (BESS). The facility is projected to supply clean energy to approximately 2.4 million households while avoiding an estimated 4.3 million tons of carbon emissions annually – equivalent to taking more than 3 million gasoline-powered vehicles off the road.
With Phase 1 on track for completion this year and Phase 2 already under construction, MTerra Solar is expected to steadily increase its capacity – delivering clean and sustainable energy for Filipinos, while supporting the Philippines’ renewable energy targets of 35% by 2030 and 50% by 2040.
