The concrete gravity dam has a height of 90 m and a length of 800 m. The dam's reservoir has a surface area of 135 km² and a capacity of 2,180 million m³.[2] 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 2003-2007 included replacing the turbines with 2 x 85 MWe units with a total capacity of 170 MWe, which generate 488 GWh per year.[2] Cerrón Grande LakeThe Cerrón Grande reservoir (Spanish: Embalse Cerrón Grande), locally known as Suchitlán Lake, is the largest body of fresh water in El Salvador.[3][4] In 2005, the reservoir and approximately {{convert|470|km2|mi2|abbr=on}} of adjacent area was listed as a "Wetland of International Importance" under the Ramsar Convention. The area provides a habitat for large numbers of waterbird, duck and fish species.[5][6] HistoryBecause of the construction of the Cerron Grande Hydroelectric Dam, over 13,000 people were displaced with many cantons or townships, caserios or hamlets, churches, cemeteries, and over 20 significant archaeological sites being lost. in the process including Canton El Tablon and Canton San Juan in Suchitoto, Cuscatlan.[7][8][9] See also{{stack|{{Portal|El Salvador|Water|Renewable energy}}}}
