ACEN extends lifespan of Southeast Asia's first wind farm in Ilocos Norte
Ayala-led ACEN Corp. has completed upgrades to its 52-megawatt (MW) NorthWind project in Bangui Bay, Ilocos Norte, extending the operational lifespan and boosting the output of Southeast Asia’s first commercial wind farm.
In a statement, the Ayala group's energy platform said the completion of the NorthWind Maintenance and Repair Program is projected to generate an additional 769 gigawatt-hours (GWh) of clean electricity over the next 10 years.
This additional generation is equivalent to powering roughly 188,000 households and avoiding approximately 592,000 tonnes of carbon dioxide emissions, according to ACEN.
Implemented in two phases between 2025 and 2026, the upgrade program involved comprehensive mechanical and electrical overhauls across all 20 wind turbines at the facility, which was originally commissioned in 2005.
ACEN said that such strategic asset optimization offers a practical blueprint for managing mature, first-generation renewable energy infrastructure worldwide. By enhancing operational efficiency rather than resorting to premature decommissioning, the company minimizes hardware waste from dismantled components while maximizing the utility of existing grid connections.
Beyond power generation, the project created local jobs during execution, with the majority of the technical and manual workforce recruited directly from host communities in Ilocos Norte.
“Building renewable energy assets is only part of the equation. Equally important is ensuring they continue operating safely, efficiently, and reliably throughout their lifecycle,” said Miguel de Jesus, ACEN Chief Operating Officer for Philippine operations.
De Jesus added that the project “demonstrates how strategic investments can maximize the value of infrastructure that’s already connected to the grid, reduce unnecessary waste from premature decommissioning, and continue delivering clean, reliable power to Filipino consumers.” (Gabriell Christel Galang)
