Meralco PowerGen Corporation (MGEN) has begun delivering electricity from its flagship solar project after energizing the facility as a generator. The milestone marks the first power injected into the Luzon grid from the MTerra Solar development.

The project is being developed by Terra Solar Philippines Inc., an affiliate of MGEN. The facility started sending its first electricity to the grid just 16 months after groundbreaking, marking a key milestone for one of the country’s largest renewable energy developments.

The initial phase of the project is expected to deliver up to 85 megawatts of mid-merit solar power to the grid. This capacity will support electricity demand during peak daytime hours and represents the project’s first delivery of power to Meralco’s network.

The energization signals the start of MTerra Solar’s operational ramp-up. The facility will gradually increase output in the coming months in coordination with the National Grid Corporation of the Philippines and in line with the project’s System Impact Study and operating 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 President and CEO Dennis B. Jordan said the project demonstrates the country’s ability to deliver large-scale renewable energy infrastructure.

“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,” Jordan said.

The project is designed to become one of the largest solar developments in the country once fully completed. The facility will generate 3,500 megawatt-peak (MWp) of solar photovoltaic capacity, supported by a 4,500 megawatt-hour battery energy storage system (BESS).

This combination of solar generation and large-scale battery storage will allow the facility to provide more stable renewable power to the grid while supporting the integration of variable energy sources.

Once fully operational, MTerra Solar is expected to supply clean electricity to approximately 2.4 million households across the country.

The project is also projected to avoid around 4.3 million tons of carbon emissions annually. This reduction is equivalent to removing more than three million gasoline-powered vehicles from the road.

The facility will be completed in two phases. Phase 1 is scheduled for completion this year, while Phase 2 is already under construction.

As both phases progress, the project’s capacity will steadily increase and provide additional renewable electricity to the grid.

The development also supports the Philippines’ national renewable energy targets. The government aims to reach 35% renewable energy share by 2030 and 50% by 2040.

Large-scale projects such as MTerra Solar are expected to contribute significantly to achieving those targets while helping diversify the country’s energy mix.

With the facility now operational and delivering its first electricity to the grid, MTerra Solar marks a major step forward for the country’s renewable energy expansion.
