Tiwi Geothermal Power Plant — 234 MW Geothermal

The Tiwi Geothermal Power Plant is a standout facility in the Philippines, recognized for its significant contribution to the country’s energy landscape. Ranking #47 of 223 power plants, this facility has a capacity of 234 MW, making it the third largest geothermal plant in the Philippines, a nation that is increasingly leaning on renewable energy sources to meet its growing energy demands. With a 0.65% share of the national capacity of 35,822 MW, Tiwi plays a vital role in diversifying the energy mix away from coal, which remains the dominant fuel source. Commissioned in 1979, Tiwi utilizes geothermal technology, tapping into the earth’s natural heat to generate electricity, thereby providing a sustainable alternative to fossil fuels. In the local context, Tiwi is strategically located near other significant energy facilities, including the San Lorenzo gas power plant (530 MW) and several geothermal plants such as Bacman and the original Tiwi plant, which each contribute to the country’s energy matrix. This cluster of geothermal generation facilities not only enhances energy security but also supports grid stability, showcasing the Philippines’ commitment to renewable energy. Nationally, the Philippines is working towards increasing its share of renewables in the energy sector, with geothermal energy being a key component of this strategy. The presence of the Tiwi plant and its peers is crucial as the country aims to reduce greenhouse gas emissions and transition to cleaner energy. As the Philippines continues to invest in renewable energy infrastructure, Tiwi’s longstanding operational history and capacity make it a cornerstone in the shift towards a more sustainable energy future. The plant’s contribution is expected to grow as the country seeks to harness its geothermal potential more effectively, paving the way for economic and environmental benefits in the years to come.
