Phase II was completed in August 2008, and added five more of the same wind turbines, bringing the total maximum capacity to 33 MW.

In 1996, the National Renewable Energy Laboratory (NREL) conducted a wind resource analysis and mapping study.

These areas include Bangui and Burgos towns in Ilocos Norte, Batanes and Babuyan Islands, which are north of Luzon and the higher interior terrain of Mindoro, Samar, Leyte, Panay, Negros, Cebu, Palawan and eastern Mindanao.

Engineer Niels Jacobsen, president and chief executive of the Northwind Power Development Corp., started work on the 24.75-megawatt project in 1999.

The Bangui Bay Project is also the first Philippine recipient of the Carbon Emission Reduction Certificates (CER's) from the executive board of the United Nations Framework Convention on Climate Change.

An additional 5 turbines brought the capacity to 33 megawatts, which was transmitted 5.7 km (3.5 mi) to an electrical substation in Laoag City.
