The 40-megawatt Limbauan solar power facility in San Pablo, Isabela, has started feeding electricity into the Luzon grid, PetroGreen Energy Corporation (PGEC) disclosed today.

Phase 2 of the project, with a capacity of 33.831 MWDC, began exporting power after the National Grid Corporation of the Philippines (NGCP) issued a provisional certificate of approval to connect (PCATC) on December 17. The plant had already been energized as a load facility on November 24.

The Limbauan plant is owned and operated by Rizal Green Energy Corporation (RGEC), a joint venture between Yuchengco-led PGEC and Japan’s Taisei Corp. It is the third operational RGEC solar facility, following the 27 MWDC Dagohoy plant in Bohol and the 19.6 MWDC San Jose facility in Nueva Ecija, which came online in July and August 2025, respectively.

“We are pleased to start exporting power from our Limbauan solar phase 2 facility which is a Green Energy Auction (GEA)-2 qualified project,” PGEC Vice President Maria Victoria Olivar said. “This milestone testifies to the strong cooperation forged among PGEC, DOE (Department of Energy), NGCP, IEMOP (Independent Electricity Market Operator of the Philippines), and the San Pablo and Isabela local governments, whose support were crucial for the project’s timely completion.”

Olivar also noted that Limbauan’s 6.006 MWDC Phase 1 and the 25 MWDC Bugallon solar facility in Pangasinan, completed last November, are awaiting NGCP clearance for energization. “Once energized, PGEC would have 263 MW of utility-scale operational renewable energy facilities,” she said. 

With PGEC and RGEC poised to add more solar capacity in the coming weeks, how significant will utility-scale solar be in shaping Luzon’s energy mix over the next five years?
