Case Study: Compañia Electrica El Platanal S.A.


Update an environmental management plan as Compañía Eléctrica El Platanal S.A. plans to expand a reservoir in Peru.

Our Approach

El Platanal, fed by the Cañete River in southern Peru’s Andean foothills, will be the country’s second largest hydroelectric plant. Project costs exceed US$200 million and operations are set to start in 2009.

Capacity for the seasonal regulation reservoir at Paucarcocha lagoon was approved at approximately 72 million yd³ in 1999, however, modifications of the project, involving the reduction of a significant section of the project, require the expansion of the reservoir to nearly 92 million yd³.

In June 2007, ERM was engaged by Compañía Eléctrica El Platanal S.A. (CELEPSA) to revise the 1999 Environmental Impact Assessment, identify and evaluate existing and further environmental impacts and formalize an Environmental Management Plan (EMP) for the seasonal regulation infrastructure of the newly designed reservoir.

Peru’s Ministry of Energy and Mines is currently reviewing the EMP.

Benefits and Value

With the approval of the revised environmental assessment and management plans, CELEPSA is raising the standard of its effective environmental commitments.
