The HPP Prelouc was built during a canalization/regulation period of the Elbe River in 1920s. It belongs among the architectonically nicest plants on the river course. After 80 years of successful operation, the plant showed major outages and low efficiency.
Building of the HPP Prelouc II., a major new plant of the bypass navigation canal, was delayed. This was the main reason for the rehabilitation of the existing Prelouc power plant.
Hydropol was fully responsible for complex design, tendering, and contracting, legal frame-work/permitting, project and site management.
The scope of the project covered: feasibility study, replacement of two Kaplan turbines and associated equipment, new substation, intake and outlet modification and civil works.
The detailed feasibility study considered the real river potential, suggested mixed scenario of rehabilitation - two turbines were refurbished while the other two were completely replaced.
The output was increased by nearly 18 % as well as the overall efficiency. This brought the best possible returns on investments.
