Gallito Ciego Hydropower Plant

Gallito Ciego is located 252 km to the north of the Cajamarca city and region. The plant islocated at the foot of the Gallito Ciego dam, which is mainly used for irrigation activities in the agricultural area of the Jequetepeque valley. The dam is not owned by Statkraft Peru, it is administered by the competent authorities.

The Plant

Gallito Ciego started operations in 1977, supplying energy to company Cementos Pacasmayo.  Subsequently, the company was incorporated as Cementos Norte Pacasmayo Energía S.A., owned by mining company Hoschild.  In 2000, all of its power generation assets were sold to the Vattenfall group, which conducted commercial operations in the National Interconnected Electrical System. In 2003, SN Power Peru acquired the hydropower plant.  Finally, in 2014, Statkrat, main shareholder of SN Power Peru, took possession of its assets and operations, and the plant became property of Statkraft Peru.

Operation

The plant is operated remotely from the dispatch center in Lima.  A compensation reservoir, which regulates the water flow that is discharged back to the river, is located downstream of the powerhouse to permit the activities in the lower basin to continue.  Consequently, the dispatch takes into consideration the water demand required for agricultural activities in the Jequetepeque river valley.

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.  Environmental controls are also in place through the environmental monitoring and solid waste management program.
