Water flowing at Cahua Hydropower Plant

Cahua Hydropower Plant, operated by Statkraft Peru.

Ownership: 100 %
Production: 290 GWh
Power: 43 MW

Cahua is located 260 kilometres to the north of the city of Lima and 60 kilometres from the highlands, on the left bank of the Pativilca river (upstream view), at an elevation of 880 metres above sea level.

Cahua is a run-of-river hydropower plant that generates power by turbining the water of the Pativilca river. As a result of the automation of the plant by the end of 2014, the plant is remotely operated from the dispatch center in Lima.

An overhaul of the plant was undertaken in 2013 and 2014, aimed at reducing the rate of failure and, therefore the operating cost. The condition of the major equipment was assessed in order to increase their efficacy and efficiency.
