It was inaugurated on 16 September 2016, and its primary purpose is the production of hydroelectric power. The US$1.4 billion project and largest power station in the country has an installed capacity of 305.5 MW and is expected to provide power for 525,000 homes. Construction on the dam began in 2009. At a height of 130 metres (430 ft) and with a structural volume of 9,000,000 m3 (12,000,000 cu yd), it is the largest dam in Central America. To produce electricity, water from the reservoir is diverted about 3 km (1.9 mi) to the northeast where it reaches the power station along the Reventazón River. Due to its environmental features, like offset habitats and migration corridors for jaguars and many other species, the project could be a model for other future hydroelectric power plants.
Hungary is a member of the European Union and thus takes part in the EU strategy to increase its share of renewable energy. The EU has adopted the 2009 Renewable Energy Directive, which included a 20% renewable energy target by 2020 for the EU. By 2030 wind should produce in average 26-35% of the EU's electricity and save Europe €56 billion a year in avoided fuel costs. The national authors of Hungary forecast is 14.7% renewables in gross energy consumption by 2020, exceeding their 13% binding target by 1.7 percentage points. Hungary is the EU country with the smallest forecast penetration of renewables of the electricity demand in 2020, namely only 11%.
