Caliraya Dam is an embankment dam located in the town of Lumban province of Laguna, in the Sierra Madre Mountain Range of the Philippines.The reservoir created by the dam, Lake Caliraya, initially supplied one of the oldest hydroelectric plants in the Philippines, and later became a popular recreational area for numerous water sports and fishing.

Pumped-storage hydroelectricity (PSH), or pumped hydroelectric energy storage (PHES), is a type of hydroelectric energy storage used by electric power systems for load balancing. A PSH system stores energy in the form of gravitational potential energy of water, pumped from a lower elevation reservoir to a higher elevation.
[3] Kalayaan is in the fourth district of the province of Laguna and can be reached three hours by land from Manila. It is the home of approximately 24,214 citizenry. The municipality is home to a hydroelectric power plant, the only pumped storage facility in the Philippines, the Kalayaan Pumped Storage Power Plant located in Brgy.
The power plant is located underground in the middle. [1] The power station employs 4 pump-generators. Unit 1 and 4 were manufactured by Hitachi, [5] while units 2 and 3 are from Mitsubishi. The maximum amount of water used by the plant is 222 cubic meters per second, for an effective storage capacity of 7 hours.
It had an original storage capacity of 9,000,000 m 3 (7,300 acre⋅ft), and was later expanded to 25,000,000 m 3 (20,000 acre⋅ft) during the Linthal 2015 expansion, to hold extra capacity for the new pumped-storage power station. A 2.2 MW solar farm was added to the Muttsee dam in 2021, supplying 3.3 GWh per year. [1]
This category is for pumped-storage power stations. For a list of pumped-storage power plants, see: List of pumped-storage hydroelectric power stations. Articles here should also have a category for Hydroelectric power stations in the appropriate country.
With a combined installed capacity of 1,600 megawatts (2,100,000 hp), [1] the system is the third largest pumped-storage power station in Japan. The facilities are run by Electric Power Development Company (J-Power). [1] Like most pumped-storage facilities, the power station uses two reservoirs, releasing and pumping as the demand rises and falls.
