The Almendra Dam, also known as Villarino Dam, in Salamanca, Spain, interrupts the course of the River Tormes five kilometres from the village from which it takes its name: Almendra (literally, almond). It was constructed between 1963 and 1970.

The arch dam forms part of the hydroelectric system known as the Saltos del Duero (in English "the Duero Drops"), along with the Castro, Ricobayo, Saucelle and Villalcampo dams of Spain, and the Bemposta, Miranda and Picote Dams of nearby Portugal.

The reservoir that backs up behind the dam covers 86.5 square kilometres and contains 2.5 billion cubic metres of water as well as several drowned villages, among them Argusinos. The dam is more than half a kilometre wide and, at a height of 202 metres, one of Spain's tallest structures.

The dam supplies the Villarino Power Station with water via a tunnel for hydroelectric power generation. It is located underground about 14 km (8.7 mi) west of the dam. Water discharged from the power station enters the Douro River. The power station has an installed capacity of 810 MW and was completed in 1977. [2]

The Kazunogawa Pumped Storage Power Station is a pumped-storage hydroelectric power station near Kōshū in Yamanashi Prefecture, Japan. The station is designed to have an installed capacity of 1,600 megawatts (2,100,000 hp) and three of the four 400 megawatts (540,000 hp) generators are currently operational, for a total operational capacity of 1200 MW. Construction on the power station began in 1993 and the first generator was commissioned on 3 December 1999. The second was commissioned on 8 June 2000. The third one became operational on 9 June 2014, six year early due to post-power demand from the Great East Japan earthquake. The fourth and final generator is slated to be commissioned by 2024. It is owned by TEPCO and was constructed at a cost of US$2.2 billion.
