MERALCO PowerGen Corp, (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.
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 Corp. of the Philippines, in line with its System Impact Study and operational plan.
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.
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.
With Phase 1 on track for completion this year and Phase 2 already under construction, MTerra Solar is expected to steadily increase its capacity.
