Assessment overview

Once commissioned, the Chaglla project will provide up to 456 MW to the national grid, making it the third largest hydroelectric power plant in Peru. It will generate approximately 6% of the country’s power and make a significant contribution to climate change mitigation, as it will displace natural gas (the default source of power in Peru), reducing annual greenhouse gas emissions by an estimated 1.8 million tCO2e. The project will not generate significant emissions from construction activities or from its small reservoir. It will boost regional socioeconomic development and help people adapt to future climate change, for example through technical assistance for cocoa and coffee production. It will also set precedents through its environmental management program, including one of the first aquatic biodiversity offsets in Latin America.

The project scored highly because its location was well selected and it was generally well designed, with a small social and environmental footprint, and because there is a high degree of corporate commitment to sustainability combined with the scrutiny of international lenders.
