According to Ministerial Resolution No. 388-2020-MINEM/ DM, the developer is contracted to ensure commercial operation of the plant by 2027 at the latest, at a total investment cost of more than US$ 988 million. The future facility, which will be located in the Huallaga river basin in the provinces of Pachitea and Huánuco, in the central region of Huánuco, will supply the National Interconnected System (SEIN).
The plant is designed to have a 183 m-high dam and a 10.8 km-long, 6.5 m-diameter headrace tunnel. The powerhouse will be equipped with three 124 MW Francis units.
Central Hidroelectrica Huallaga Hydro was awarded an environmental permit for the project by the environmental affairs office (DGAAE) of Peru’s Ministry of Energy and Mines in October 2018 (see H&D Issue 6, 2018).
Huallaga I is one of three hydro schemes that Grupo Ibereolica Renovables is developing in Peru. It is also planning the 186 MW Apurimac plant in the province of Paruro, in the southern highlands, and the 20 MW Las Orquideas project in the Rioja province, in the northern region of San Martín.
