Vietnam’s VinEnergo and Philippine renewable energy developer SunAsia Energy Inc. have forged a strategic partnership to develop three large-scale solar projects worth more than $1.5 billion in projected lifetime revenues, underscoring growing regional investment in the country’s clean energy sector.
The projects will use the Solar on Stilts model, which mounts solar panels on elevated pile structures to optimize land use while improving resilience against flooding and other climate-related risks.
The companies aim to bring the projects into commercial operation between 2027 and 2028, adding a combined 422 megawatts-peak (MWp) of renewable energy capacity. The pipeline includes a 181-MWp facility in Macabebe, Pampanga, a 126-MWp plant in Sagay City, Negros Occidental, and a 115-MWp project in Silay City, Negros Occidental.
Once completed, the facilities are expected to supply clean electricity to about 278,000 households while reducing carbon emissions by more than 460,000 metric tons annually, roughly equivalent to planting 21 million trees.
Beyond expanding renewable power capacity, the partnership highlights increasing cross-border investment in the Philippines’ energy transition as developers race to meet rising electricity demand and the government’s renewable energy targets.
Over the next 18 months, VinEnergo and SunAsia will finalize engineering designs and oversee project execution, including the selection of engineering firms, technology providers and contractors. The developments will require the installation of nearly 700,000 solar panels and about 62 kilometers of new transmission lines across Pampanga and Negros Occidental.
The agreement was signed by SunAsia Energy Chairperson and Chief Executive Officer Tetchi Capellan and VinEnergo Chief Executive Officer Nguyen Anh Khoa in the presence of Energy Secretary Sharon Garin and Vietnamese Ambassador to the Philippines Lai Thai Binh.
The venture reinforces the Philippines’ appeal as a destination for renewable energy investments, with foreign developers increasingly partnering with local firms to accelerate project deployment amid rising power demand and the push for a cleaner energy mix.
