Petit Saut Hydroelectric Power Plant, French Guiana | 113.6 MW Facility

Petit Saut is a hydroelectric power plant located in French Guiana, an overseas department of France. With a capacity of 113.6 MW, it is a medium-scale facility that plays a key role in the region's electricity supply. The plant is owned and operated by Électricité de France (EDF), the state-owned utility. As a hydroelectric facility, Petit Saut uses the flow of water to generate electricity without direct fuel combustion, resulting in low greenhouse gas emissions. The plant operates under French and EU environmental regulations, including the EU Water Framework Directive and the Industrial Emissions Directive. Its technology is typical for run-of-river or reservoir-based hydro projects in tropical regions. The plant contributes to French Guiana's energy mix, reducing reliance on imported fossil fuels. It supports local communities and economic activities by providing stable power. The reservoir created by the dam also influences local hydrology and ecosystems, requiring careful management to balance energy production with environmental stewardship.

The Petit Saut plant is located in a tropical rainforest region of French Guiana, an area of high biodiversity. The reservoir created by the dam has altered local aquatic habitats and may affect downstream ecosystems. As a hydroelectric facility, it produces no direct air emissions, but the flooding of land can release methane from decomposing vegetation. The plant's operation is subject to environmental monitoring to mitigate impacts on water quality and wildlife.
