Petrohan Cascade, Hydroelectric cascade in Barzia, Bulgaria.
Petrohan Cascade is a series of three hydroelectric power plants built along a river valley in Barzia. The system harnesses flowing water to generate electricity through different types of turbines positioned at various elevations.
The first power plant started operating in 1956 as part of Bulgaria's effort to modernize its energy production after World War II. The three facilities were developed over time to maximize the use of water resources in the region.
The three power plants of Petrohan Cascade supply electricity to nearby communities while creating employment opportunities for local residents.
The plants are located in a mountainous area with walking paths nearby that offer views of the valley. A car is the best way to explore the full system, as the three facilities are spread across several kilometers.
Each power plant in the cascade system maintains specific water flow patterns to maximize energy production throughout different seasons.
