We’ve already seen a wind power plant, a hydroelectric power plant (though indirectly), a coal-fired power plant, a natural gas power plant, and a solar power plant, so let’s add one more type of electricity-generating facility by introducing the Tiwi Geothermal Power Plant in Tiwi, Albay on the northeastern flanks of Mt. Malinao.
The Tiwi Geothermal Power Plant actually consists of three separate plants. What you can see in the satellite image thumbnail is Plant A, while Plant B is located roughly a kilometer to the east-southeast, and Plant C about a kilometer to the southwest. These three plants have a combined 275 megawatts of generating capacity.
These three plants harness geothermal energy in the area known as the Tiwi Geothermal Field. This is part of the 17,661-hectare geothermal area in Albay that was reserved by Pres. Marcos through Presidential Decree No. 739 in 1970 following the passage of Republic Act No. 5092 or the Geothermal Law in 1967. The harnessing of geothermal energy was quite timely since it helped saved the Philippines millions of dollars during the 1970s oil crisis.
The Tiwi webpage from the National Geothermal Association of the Philippines would prove informative if you wish to learn more.
