History of Hydroelectric Power in the Philippines
In 1913, the first hydroelectric power plant in the Philippines was installed in Camp John Hay
located in Baguio, however, it wasn’t until 1942 when the first Philippine Commissioned dam
was finished. The Caliraya dam, now decommissioned, was the country’s first official foray into
hydroelectric power plants (Mcintyre, 1955). Postwar rehabilitation plans included the
construction of a number of small power plants scattered around the country wherever fit, and
due to the topographical features of our country which is favorable to hydroelectric plants
(Cembalest, 2020), continued support for building has not been met with widespread opposition.
Today, the country procures twelve percent of its energy from hydro plants, eighteen of which
are large plants which provide 10MWs individually. According to the DOE, there is around 85
percent of untapped hydroelectric power left to be harnessed, most of which are deemed to be
appropriate for large hydro plants. (Agaton, 2018).
