The Bangui Windmills are located in Bangui, Ilocos Norte, Philippines. The windmills, officially referred to as the NorthWind Bangui Bay Project, were a project by the NorthWind Development Corporation as a practice renewable energy sources and to help reduce the greenhouse gases that cause global warming. The project is the first “Wind Farm” in the Philippines consisting of wind turbines on-shore facing the South China Sea and considered to be the biggest in Southeast Asia. The project sells electricity to the Ilocos Norte Electric Cooperative (INEC) and provides 40% of the power requirements of Ilocos Norte via Transco Laoag.

Each wind turbine is capable of producing electricity up to a maximum capacity of 1.65MW, totaling to 24.75MW in all. They have three vertically oriented rotor blades on top of a 50m-high tubular tower. The nacelle (casing), which encloses the generator, the gear box and the yaw mechanism (which turns the blades into the wind), is at the rear of the rotor blades. Each wind turbine has a 6-meter diameter base.

The wind turbines capture wind energy and transformed by electrical generators to be transformed into usable energy. The NorthWind Bangui Bay Project produces a total of 74,482MWh of electricity annually. Electricity generated by the wind mills will be sold to INEC under a 21-year Electricity Sales Agreement (ESA) at PhP 4.43/kWh. The expected life of the equipment is 21 years.

The Northwind Bangui Bay Project approximates that 56,788tCO2e (tons of carbon dioxide equivalent) of Greenhouse Gases will be reduced per year for the duration of the project activity.

To ensure that the wind power project would not cause transmission line overloads or instability, a System Impact Study for the project conducted by the NPC (National Power Corporation), which includes a power system simulation study to investigate the system performance of the induction generators and studies of loadflow and stability to determine the adequacy of the power grid. The study indicated that grid reinforcements and improvements in the form of new transmission substation facilities and power conditioning devices like capacitor banks.
