Petrohan Cascade, Hydroelectric cascade in Barzia, Bulgaria.
The Petrohan Cascade includes three power plants: Barzia HPP, Petrohan HPP, and Klisura HPP, generating electricity through Pelton and Francis turbines.
The cascade system began operations in 1956, marking a significant advancement in Bulgaria's post-World War II energy infrastructure development.
The three power plants of Petrohan Cascade supply electricity to nearby communities while creating employment opportunities for local residents.
The Barzia hydropower plant produces 26 gigawatt-hours annually, while Petrohan generates 23 gigawatt-hours and Klisura contributes 14 gigawatt-hours.
Each power plant in the cascade system maintains specific water flow patterns to maximize energy production throughout different seasons.
