The Cerrón Grande Hydroelectric Dam (Central Hidroeléctrica Cerrón Grande) spans the Lempa River 78 km (48 mi) north of San Salvador in the municipalities of Potonico, (Chalatenango) and Jutiapa (Cabañas) in El Salvador. The concrete gravity dam has a height of 90 m (300 ft) and a length of 800 m (2, 600 ft). The dam's reservoir has a surface area of 135 km2 (52 sq mi) and a capacity of 2,180,000 cubic metres (77, 000, 000 cu ft). The hydroelectric power plant was fitted with 2 x 67.5 MWe Francis turbines with a total capacity of 135 Mwe. Major maintenance work carried out between 2003 and 2007 included replacing the turbines with 2 x 85 MWe units with a total capacity of 170 MWe, which generate 488 GWh per year.
