MGEN’s MTerra Solar Project Achieves Grid Synchronization, Sends First Power to Luzon Grid

Meralco PowerGen Corporation (MGEN), through its affiliate Terra Solar Philippines Inc., has successfully completed the initial grid synchronization and energization of the MTerra Solar project, marking a key milestone in the development of one of the Philippines’ largest solar energy projects.

The synchronization confirms that the facility is ready for safe integration into the Luzon grid, with the first electricity from the project already transmitted to the system. The milestone was achieved 16 months after the project’s groundbreaking, signaling the transition of the facility into its operational phase.

During this initial stage, the project is expected to supply up to 85 megawatts (MW) of mid-merit power, helping meet daytime electricity demand and marking the first energy delivery to Manila Electric Company (Meralco).

Following the energization, the project will gradually increase its power generation capacity in coordination with the National Grid Corporation of the Philippines, in accordance with the System Impact Study and operational integration plan.

Emmanuel V. Rubio, President and CEO of MGEN, described the milestone as a significant step toward strengthening the country’s energy security. He noted that the facility’s launch begins a broader phase of scaling up generation capacity to support growing energy demand and enhance national energy self-reliance.

Meanwhile, Dennis B. Jordan, President and CEO of Terra Solar Philippines Inc., highlighted that the project reflects local engineering capability and is designed to deliver reliable and clean electricity to communities and industries across the country.

Once fully completed, the MTerra Solar facility is expected to generate 3,500 MWp of solar photovoltaic capacity, supported by a 4,500 MWh battery energy storage system (BESS). The project is projected to supply renewable power to approximately 2.4 million households while avoiding around 4.3 million tons of carbon emissions annually, equivalent to removing more than three million gasoline-powered vehicles from the roads.

With Phase 1 scheduled for completion this year and Phase 2 already under construction, the project is expected to gradually expand its output and contribute to the Philippines’ renewable energy targets of 35% by 2030 and 50% by 2040.
