[1] The idea for the construction of power plants along the Vacha River utilising the catchment area in the Western Rhodopes, dates back to 1920, when engineer Ivan Mavrov proposed it in his work "Archive of Water Power in Bulgaria".

The conceptual and technical design for the entire "Batak Hydropower Cascade" was developed between 1951 and 1955 in "Hydro Energy Project".

[3] The turbines are driven by water that comes from the Golyam Beglik dam via a pressure diversion.

The electricity generated is exported to an above-ground 10 kV system via tunnels and bare conductor rails.

The waste water from the power plant is channelled via a 3 km long unpressurised sewer with a cross-section of 2.80 m x 2.80 m to the "Nova Mahala" collection tank, which then flows into the Batak Reservoir.
