Meralco PowerGen Corporation (MGEN), through its affiliate Terra Solar Philippines Inc. (MTerra Solar), has reached a significant milestone in the construction of the MTerra Solar plant—with 778 megawatts (MW) of solar photovoltaic (PV) panels now installed on-site.
This achievement exceeds the project’s 750 MW target and positions MTerra Solar as the largest solar PV installation in the Philippines to date. Once complete, it is expected to become the world’s largest integrated solar PV and battery energy storage facility.
“MTerra Solar stands as a clear example of how we can shape the country’s energy future through strong partnerships and a shared vision. With 778 MW of solar PV capacity now installed, we are making real progress toward delivering cleaner and more sustainable power for Filipinos,” said Dennis B. Jordan, MTerra Solar and MGEN Renewable Energy president and CEO.
“This milestone reflects the hard work of our teams on the ground, the support of our government partners, and the trust of the communities we serve,” Jordan said.
Since the project’s groundbreaking in November 2024—led by President Ferdinand “Bongbong” Marcos Jr.—MTerra Solar has reached 54 percent overall completion for Phase 1. The integrated PV and battery energy storage system (BESS), along with a 500‑kilovolt transmission line to the Nagsaag‑San Jose corridor, is supported by a workforce of over 9,500, which has logged more than 7.5 million safe manhours.
The facility is a critical element of the Philippines’ plan to achieve 35 percent renewable energy by 2030 and 50 percent by 2040.
Local officials hailed the project’s community and economic benefits.
“At the heart of our provincial agenda is the vision of sustainable, inclusive and future‑forward development. The provincial government of Nueva Ecija will continue to champion projects like MTerra Solar. It is our duty to pave the way for a future that is not only bright but also clean, green and just,” said Governor Aurelio “Oyie” Umali, represented by Provincial Administrator Atty. Jose Maria San Pedro.
For his part, Gapan City Mayor Emary Joy Pascual added, “Nakakatuwa dahil libo-libong trabaho at negosyo ang naging oportunidad dito sa Lungsod ng Gapan at pakikinabangan ng mga Batang Gapan.”
“[We also express our] deep appreciation that a great number of the workforce is now providing livelihood... The strong partnership that we build today is a commitment to improve lives of our people now and beyond,” said General Tinio Mayor Sherry Bolisay.
Spanning 3,500 hectares—nearly the size of Pasig City—the project stretches across Gapan, Peñaranda, General Tinio, San Leonardo in Nueva Ecija, and San Miguel in Bulacan. Once fully operational, MTerra Solar will deliver 3,500 MWp of solar capacity and 4,500 MWh of energy storage, powering some 2.4 million households and avoiding approximately 4.3 million tons of CO₂ emissions yearly—equivalent to taking over 3 million gasoline-powered vehicles off the road.
Constructed with the support of EPC leaders Energy China, POWERCHINA, MIESCOR, and Huawei, as well as grid interconnection specialists Maxipro Development and Fujian Electric, the project is on schedule to complete Phase 1 by early 2026 and Phase 2 in 2027—three years ahead of MGEN’s 2030 renewable capacity goal.
MGEN’s broader portfolio now boasts nearly 5,000 MW of combined capacity across traditional and renewable sources.
