MGEN Renewable Energy Inc. (MGreen), the renewable energy arm of Meralco PowerGen Corporation (MGEN), has achieved 42% overall progress on its flagship MTerra Solar project, the largest integrated solar and battery energy storage system (BESS) facility in the world.
The milestone was announced at Solar & Storage Live Philippines 2025, where MGreen highlighted the ongoing construction activity and local development programs linked to the project. Located across over 3,500 hectares in Nueva Ecija and Bulacan, MTerra Solar will deliver 3,500 megawatts-peak (MWp) of solar power and 4,500 megawatt-hours (MWh) of energy storage once completed.
Phase 1 remains on track for completion by the first quarter of 2026. The facility also includes a 13-kilometer, 500-kilovolt transmission line that will directly connect the site to the national grid.
In his keynote speech, MGreen and Terra Solar Philippines President and CEO Dennis Jordan emphasized that large-scale renewable projects must deliver not only energy but also economic opportunity.
“Our 42% overall progress rate shows the dedication of the team that we have here in the Philippines,” Jordan said. “This isn’t a distant vision—it’s alive, it’s growing, and it’s being built with world-class engineering, environmental safeguards, and Filipino talents.”
More than 5,000 contractors are currently deployed on-site, with total workforce numbers projected to peak at 16,000 during the height of construction.
To support local employment and skills development, MGreen launched the TERRAnsform program in partnership with the Meralco Power Academy and local government units. The initiative is training 600 scholars in renewable energy construction and operations. Sixty scholars have already graduated and are now working with MTerra Solar’s engineering, procurement, and construction (EPC) partners.
“We want MTerra Solar to benefit not just the energy sector, but also the communities hosting it,” Jordan added. “This is what inclusive energy development looks like.”
Once operational, MTerra Solar is expected to supply clean electricity to about 2.4 million households and displace an estimated 4.3 million tons of carbon emissions annually—the equivalent of removing 3 million gasoline-powered cars from the road.
In the first quarter of 2025, MGreen also completed three new solar farms, bringing MGEN’s renewable energy portfolio to nearly 400 MWac of net sellable capacity across seven provinces: Bulacan, Isabela, Nueva Ecija, Rizal, Ilocos Norte, Tarlac, and Batangas. The company is now on pace to exceed its 1,500 MW clean energy target by 2027—three years ahead of its original 2030 timeline.
Solar & Storage Live Philippines 2025 convened stakeholders from government, industry, and civil society to accelerate the country’s transition to renewable energy. MGreen’s participation reaffirmed its alignment with national targets of achieving 35% renewable energy in the power mix by 2030 and 50% by 2040.
