Alternergy Holdings Corp. said Thursday it received approval from the National Grid Corporation of the Philippines (NGCP) for the system impact study (SIS) for all five renewable power projects the company won under the Green Energy Auction 4 (GEA 4) Program.
The approval is a significant step toward developing the projects, which have a potential new capacity of up to 500 megawatts (MW) and boost Alternergy’s goal of reaching One Green Gigawatt by 2030.
“The NGCP approval of the SIS is a significant step to move our projects forward. It confirms the grid’s capability and readiness to accommodate and integrate our projects into the system,” said Alternergy president Gerry Magbanua.
The completion and approval of the SIS is a critical post-auction requirement under GEA 4, and the company confirmed it successfully submitted all necessary documents to the Department of Energy (DOE).
“We are excited to hit the ground running and start the development works,” Magbanua said.
The five projects include the Liberty Solar Floating Projects Phase A and Phase B in Luzon and the Kalandagan Solar Power Project with Battery Energy Storage System in Mindanao. Alternergy also won two wind projects: the Tayabas North Wind Energy Project in Luzon and the Alegria Wind Power Project in the Visayas.
Alternergy targets to start commercial operations for its 128-MW Tanay and 64-MW Alabat wind projects in the first half of 2026 and expects to begin booking revenues from these nearly 200 MW of additional capacity around that same timeframe.
