  • UKRENERGO JOINS EFFORTS ON IMPROVING THE QUALITY OF WATER IN THE KYIV RESERVOIR

    During the heatwave from June 20 to June 26, Ukrenergo will ensure the round-the-clock water passage at the Kyivska HPP. The State Agency of Water Resources appealed to Ukrenergo in order to improve water quality and flow in the Kyiv reservoir.

    According to the State Agency of Water Resources, the water temperature in the Kyiv reservoir reaches 25-27°C, which leads to lower oxygen content in water and the growth of algae. In addition, the water quality in the Dnieper is influenced by the inflow waters of the Pripyat, which now have worse quality indicators.

    Water treatment by the turbines of the Kyivska HPP will reduce the temperature of the water and saturate it with oxygen.

    For the environment Hydro Power Plants mean protection against floods and rain floods, water supply of the river deltas during spawning period, as well as improvement of the ecological situation and conditions of water bioresources in reservoirs.

    For the power system, HPPs and PSPPs are key in covering peak and half-peak loads. Their merit is in high flexibility (fast start-up and change in capacity), ability to provide emergency reserve (water supply up to 3 hours of operation), frequency reserve and fill the off-peak load (PSPP in pumping operation).

    In Ukraine, there are 10 large HPPs and PSPPs on the Dnipro and the Dniester, which are part of PrJSC Ukrhydroenergo. The total installed capacity of the 103 hydro units of these power plants is 5758 MW. The capacity of the Kyivska HPP is 493 MW, in 2018 the plant generated 915 million kWh of electricity, which is about 7.6% of the total HPP generation.
