Alternergy’s 64-MW Alabat wind farm starts feeding Luzon grid

MANILA, Nov. 3, 2026 — Alternergy Holdings Corp. said on Tuesday that it has energized its 64-megawatt (MW) Alabat Wind Farm in Quezon province, with the first three turbines now sending power to the Luzon grid as the northeast monsoon, or amihan, sets in.

The P6.7-billion project is among the first wind farms awarded under the Department of Energy’s second Green Energy Auction (GEA-2) to reach transmission-line energization, and the first in Quezon to do so under the program, the company said.

Alabat uses eight 8-MW turbines, which Alternergy describes as the largest installed in Southeast Asia outside China. The three running units are earning pre-commissioning revenue while the company completes the testing and commissioning needed for commercial operation.

Power travels over a 37-kilometer, 69-kilovolt line to the National Grid Corp. of the Philippines’ Gumaca-Lopez (Hondagua) line. The link includes a 1.4-kilometer overhead sea crossing between Alabat Island and the Luzon mainland, which the company says is a first for a Philippine wind project.

At full output, the wind farm is expected to produce about 202 gigawatt-hours a year, which Alternergy says could supply roughly 218,500 households and avoid about 150,541 metric tons of carbon emissions annually.

Company president Gerry Magbanua said the focus has shifted to finishing the remaining work required to declare commercial operations. BusinessWorld reported that no commercial operation date has been announced, while the Philippine Daily Inquirer said the company expects the facility to be fully running within the year.

Alabat and the 128-MW Tanay wind project in Rizal are expected to lift Alternergy’s operating capacity to about 311 MW by end-2026 from 119 MW, BusinessWorld said. A Brown Co.’s ABC Energy holds a 40% stake in each of the two wind projects. Alternergy is targeting 1,000 MW of renewable capacity by 2030.

What it means for consumers

New wind capacity adds supply to the Luzon grid during the amihan months, when winds are strongest. Its effect on any single household bill is indirect and depends on how the output is priced and contracted under the auction.
