With its exposed location between the South China Sea and the Philippine Basin, the north coast of the main Philippine island of Luzon enjoys high winds. The North Wind Bangui Bay Project uses these favourable conditions to generate electricity from wind power. After conducting an environmental impact assessment and obtaining certification from the Philippine government, the country’s first wind farm was erected along an approximately nine kilometre-long and 100 metre wide stretch of the coast. The energy produced by the 20 wind turbines is transported over a 50 kilometre long overhead transmission line and is then fed into the local grid. The state of the art turbines each have a capacity of 1650 kW. In cooperation with the Philippines-based North Wind Power Development Corporation, the project is jointly implemented by seven European states as well as Canada and Japan. The International Bank for Reconstruction and Development acts as trustee on behalf of the World Bank Prototype Carbon Fund.
To quantify the emission reductions achieved with the project, the emissions must be calculated for the quantity of electricity generated by the wind farm if it had been produced by generic means. In doing so, the existing CO2 intensity of the Philippine electricity grid was used, which is comparatively high due to the percentage of fossil fuels involved. If the expected electricity generated by the wind farm was supplied by conventional power stations, annual emissions would amount to 56,788 tCO2e. Because wind-generated electricity is a zero emissions process, the annual emissions can be reduced in their entirety. In the seven years of the first lifecycle, emission reductions of almost 400,000 tCO2e are expected. The project lifecycle is to be extended twice, making for an overall performance period of 21 years and total emission reductions of 1.19 million tCO2e.
Without the CDM, the project could not have been implemented because the funding could not have been secured due to the project’s low viability. As a CDM project, the wind farm generates emissions certificates which can subsequently be traded. The revenue from the sale of these certificates helps to fund the project and increase its viability.
Whether the emission reductions expected from a CDM project can actually be achieved must be ascertained by monitoring key factors across the entire project lifecycle. The amount of electricity fed into the regional and super-regional grid is recorded electronically and compiled into monthly statistics. Also, the socio-environmental impacts on the region and its inhabitants are monitored to ensure the project is sustainable.
Work on the first construction phase began in May 2004 and was concluded a year later, with the first 15 wind turbines going into operation. In August 2008, the remaining five turbines were installed, making for a total wind farm capacity of 33 MW. The project avoided in its first crediting period 321,009 tCO2e or 45,858 tCO2 a year. After the first period has ended, the project operators successfully obtained approval to extend the project lifecycle. On 1 November 2012 the project achieved renewal until 30 April 2019. The expected reductions for the second period amount to 43,696 tCO2e a year.
