Subject of the Disclosure
Alternergy completes Philippines’ first sea-crossing transmission link for a wind power project
Background/Description of the Disclosure
Alternergy Holdings Corporation (“ALTER”), a Philippine pioneer in renewable power development, through its subsidiary Alabat Wind Power Corp. (“AWPC”), has completed the Philippines’ first overhead sea-crossing transmission link built for a wind power project, establishing a critical connection between its 64-megawatt (“MW”) Alabat Wind Project in Quezon Province and the Luzon mainland. Spanning 1.4 kilometers, the overhead crossing forms part of the project’s 37-kilometer, 69-kilovolt (“kV”) transmission line. The crossing required two 100-meter-tall and two 45-meter-tall lattice towers, providing the infrastructure needed to transfer electricity from Alabat island to the Luzon grid. This project marks ALTER’s first inter-island transmission connection and demonstrates the company’s capability to deliver complex energy infrastructure in challenging geographic and engineering conditions.
