PJSC RusHydro has begun construction of two small hydropower plants — Krasnogorskaya-1 and Krasnogorskaya-2 — on the Kuban River in Karachay-Cherkessia Republic.
According to a press release issued in June, RusHydro plans to build two hydropower stations, each with installed capacity of 24.9 MW and annual output of 83.8 GWh, downstream from its 160-MW Zelenchukskaya hydro and pumped storage power plant. The new facilities are to be commissioned in 2021 to 2022.
The new facilities will improve the hydrological regime of the Kuban River, lifting limitations on the capacity of Zelenchukskaya, which is currently set at 70 MW, RusHydro says. The regime optimization will add 230 GWh to the output of the Kuban Cascade annually.
The project will create 700 new jobs for the construction period.
Mosoblhydroproject, RusHydro’s engineering subsidiary, designed the plants.
“Development of renewable generation such as small hydro has always been an important part of business for RusHydro,” said Nikolay Shulginov, chairman of the management board — general director of RusHydro. “Within the year, we plan to commence construction of three small HPPs in the North Caucasus region and today we lay the foundation for construction of two Krasnogorskaya-1 and 2 small HPPs. Despite their small-scale these plants will have a significant positive impact on the power system of the Karachay-Cherkessia Republic.”
RusHydro is actively developing hydropower generation in Karachay-Cherkessia. In 2016, the company commissioned two hydropower units of the Zelenchukskaya HPP-PSP with capacity of 140 MW/156 MW (generation mode /pumping mode) and in 2018 commissioned a small HPP on the Zelenchuk River with capacity of 1.2 MW. Construction of the 5.6-MW Ust-Dzhegutinskaya HPP is in progress.
