Meralco PowerGen Corporation's inauguration of the 1373 MW Mterra Solar Phase 1 project in the Philippines is a significant milestone in the country's renewable energy journey. This ambitious project, a collaboration between MGEN and its partners, is set to become one of the world's largest integrated solar photovoltaic (PV) and battery energy storage system (BESS) facilities on a single site. The inauguration marks a turning point in the Philippines' ability to develop large-scale clean energy infrastructure, supporting a more reliable, affordable, and sustainable electricity system.
The event was graced by the presence of Philippine President Ferdinand R. Marcos Jr., who emphasized the project's global significance. He highlighted that the successful completion of Phase 1 demonstrates the Philippines' capability to turn ambitious clean energy plans into reality. This project is a testament to the country's commitment to renewable energy and its potential to become a global leader in the field.
MGEN Chairman Manuel V. Pangilinan shared the sentiment, describing the project as a significant achievement for the nation. He noted that the integrated solar and battery storage facility is set to become the world's largest of its kind on a single site, a feat made possible through the combined efforts of the government, private sector, local communities, and thousands of Filipino workers. This collaborative approach is a key strength of the project, fostering a sense of national pride and unity.
Phase 1 of MTerra Solar has energized 1,373 MW of solar PV capacity along with 825 MW of battery energy storage, equivalent to 3,300 MWh. Despite the current maximum export capacity of 750 MW to the Luzon grid, the project has already achieved a remarkable milestone by fully energizing all 741 battery units. This enables the facility to store solar power generated during the day and supply electricity when demand is highest, improving grid stability and energy security.
The project is now ready to fulfill its 600 MW mid-merit Power Supply Agreement (PSA) with Meralco. By the end of June 2026, more than 2,000 MWdc of solar panels had already been installed under Phase 1. Safety is also a priority, as the project has recorded over 30 million work hours without a lost-time injury, a testament to the dedication and professionalism of the workforce.
MGEN President and CEO Emmanuel V. Rubio emphasized the company's commitment to ensuring that the energy transition delivers not only cleaner electricity but also reliable and affordable power for Filipino consumers. He highlighted that MTerra Solar demonstrates how innovation, collaboration, and long-term planning can strengthen the country's energy system while supporting future economic growth.
The project is expected to reduce the Philippines' dependence on imported fuels by adding significant domestic renewable energy capacity to the Luzon grid. As one of the lowest-cost mid-merit power sources in Meralco's supply portfolio, the facility will help diversify electricity generation while supporting the country's renewable energy targets of achieving 35% renewable energy by 2030 and 50% by 2040.
Actis Managing Director and Head of Energy Infrastructure Lucy Heintz praised the project's contribution to the country's energy security, providing over 1,373 MW of domestic clean energy while offering industries and consumers greater visibility over future electricity costs. The Philippines, she said, is demonstrating leadership in delivering large-scale renewable energy solutions.
Beyond electricity generation, MTerra Solar is creating economic and social benefits for local communities. MGEN Renewables and Terra Solar Philippines Inc. President and CEO Dennis B. Jordan highlighted the company's investment of PHP 88.6 million in education, livelihood programs, public safety, and community development initiatives. Since construction began, the project has benefited more than 973,500 individuals and 47 institutions.
Local residents have received technical training for renewable energy construction and operations, securing jobs on the project. The company has also installed 260 solar-powered streetlights, established rent-free marketplace spaces for local entrepreneurs, trained 214 community traffic marshals, created 17 traffic marshal posts, donated a fire truck, and built a fire substation in Gapan City to improve emergency response.
MTerra Solar is also promoting sustainable land use through a partnership with Central Luzon State University to research agrivoltaics. The studies will examine how crops can be cultivated around and beneath solar panels, helping improve farmer livelihoods, strengthen food security, and encourage more sustainable agricultural practices alongside renewable energy development.
In conclusion, the inauguration of MTerra Solar Phase 1 is a significant step forward in the Philippines' renewable energy journey. It showcases the country's capability to develop large-scale clean energy infrastructure, supports a more sustainable future, and creates economic and social benefits for local communities. As the project continues to unfold, it will undoubtedly leave a lasting impact on the Philippines' energy landscape and global renewable energy efforts.
