Malpaso Hydropower Plant

The Malpaso hydropower plant is located in the district of Paccha, department of Junin, at 3,870 masl.

The Plant

Malpaso, together with La Oroya and Pachachaca hydropower plants, was initially constructed to supply the demand arising out of the mining activities of Cerro de Pasco Copper Corporation, forming the Electricity and Telecommunications Department (DET) of the mining company.  In 2001, the DET assets were sold to company Electroandes, a company that was privatized and acquired by PSEG Global in the same year, and operated the plant until 2007.  By the end of that year, SN Power Peru acquired the assets of La Oroya HPP. Finally, in 2014, Statkraft, main shareholder of SN Power Peru, took over its assets and operation.


The Malpaso hydropower plant makes use of part of the water from the Mantaro river for power generation.  Due to the proximity of the powerhouse to the Malpaso reservoir, where the water taken in from the Mantaro river is stored, the plant has the capacity to quickly increase or decrease the generation capacity based on requests and demands.  This plant is remotely operated from the dispatch center of Statkraft Peru in Lima.

Corporate Responsibility

Statkraft Peru has been conducting corporate responsibility programs regarding the building of capacities and educational competences in the schools within the area of influence of the hydropower plant.  Additionally, environmental controls are in place as part of the environmental monitoring program and solid waste integral management.
