The Popina Laka HPP is in the chain of three plants, utilizing enormous potential of the Pirin range in Bulgaria.
The cascade's total installed output exceeds 50 MW of pure peaking power. This is the largest hydropower plant out of a group of private hydropower plants in Bulgaria.
The scope of project included turbine modifi-cations, generator rehabilitation, new protection and control system, and replacement of new substations and hydromechanical equipment.
The task of Hydropol was to analyze the cascade operation in detail, design a new optimized operation mode, and develop full rehabilitation design, tendering and quality management documentation.
