Listed renewable energy developer Alternergy Holdings Corp. has completed the Philippines’ first overhead sea-crossing transmission link built specifically for a wind power project, a key milestone that connects clean energy generated on Alabat Island directly to the Luzon mainland grid.
Built through its subsidiary Alabat Wind Power Corp., the 1.4-kilometer sea crossing forms part of a wider 37-kilometer, 69-kilovolt transmission line linking the 64-megawatt Alabat Wind Project in Quezon Province to the National Grid Corporation of the Philippines’ Gumaca–Lopez (Hondagua) line. The structure required two 100-meter and two 45-meter lattice towers to span the channel, with the full route supported by 483 poles in total. The company did not disclose the total investment cost for the facility.
For Alternergy, the link represents its very first inter-island transmission connection, underscoring its ability to deliver complex energy infrastructure even in geographically challenging locations. “Developing a wind project on an island requires more than building the generating facility itself. It also means creating the infrastructure needed to deliver clean power to consumers,” said Gerry Magbanua, president of Alternergy Holdings. “The Alabat sea crossing addresses that challenge and demonstrates our ability to deliver complex infrastructure that unlocks the potential of the country’s renewable energy resources.”
Consumers stand to gain from steady supplies of clean, renewable power from the new facility. The wind farm itself features eight turbines each capable of producing 8 megawatts — the largest commercial wind turbines deployed outside China, designed to withstand the country’s frequent typhoons. It is also Quezon Province’s first wind farm, and one of the early projects completed under the Department of Energy’s second Green Energy Auction Program.
With this link in place, the Alabat facility plus the upcoming 128-megawatt Tanay Wind Power Project in Rizal will lift Alternergy’s total operating capacity from 119 megawatts to around 311 megawatts by the end of 2026, substantially expanding the volume of renewable energy feeding into the Luzon grid.
