Power has been restored to over 800,000 residents in Kyiv, a day after Russia launched major attacks on Ukraine's power grid, causing widespread blackouts.
The United States Agency for International Development (USAID), through the Energy Security Project, transferred 137 generators worth about UAH 40 mln to the Communal Utility Kyivteploenergo (CU KTE).
"Emergency repair work is ongoing, and most consumers had their power restored by Monday morning," it said. Mykola Kalashnyk, the governor of Kyiv region, said the attack had damaged the local gas grid and that over 8,000 properties in eight settlements would be disconnected from their gas supply over the next two days as repairs were carried out.
The CU Kyivteploenergo’s staff quickly mastered the algorithms of switching the boiler houses to generators. Those processes, earlier practiced during training sessions on generator usage, became a part of their routine work. “During emergency power outages, the generators enabled us to be ready for a blackout scenario.
Kyiv wants to up this to 27% by 2030. Other similar energy storage systems in Eastern Europe include Lithuanian electricity transmission system operator Litgrid's 200-MW units launched in 2023 and a 55-MW battery energy storage system in Razlog in southwestern Bulgaria that went online in 2024.

The Kyiv Pumped-Storage Power Plant ( Ukrainian: Ки́ївська гідроакумулювальна електростанція) is a pumped-storage power station on the west bank of the Kyiv Reservoir in Vyshhorod, Ukraine. The Kyiv Reservoir serves as the lower reservoir and the upper reservoir is located 70 m (230 ft) above the lower.
Battery energy storage facilities are like a large power bank connected to energy grids, and are crucial for storing energy created by renewables like solar and wind for later use. The share of renewable energy in Ukraine's grid was about 10% before Russia’s full-scale invasion. Kyiv wants to up this to 27% by 2030.
A battery energy storage system (BESS), battery storage power station, battery energy grid storage (BEGS) or battery grid storage is a type of energy storage technology that uses a group of batteries in the grid to store electrical energy.
Battery energy storage systems are generally designed to deliver their full rated power for durations ranging from 1 to 4 hours, with emerging technologies extending this to longer durations to meet evolving grid demands.
As with a UPS, one concern is that electrochemical energy is stored or emitted in the form of direct current (DC), while electric power networks are usually operated with alternating current (AC). For this reason, additional inverters are needed to connect the battery storage power plants to the high voltage network.
The volumes of electrical energy produced in the Russia by solar and wind power plants, as well as their current and prospective role in the energy balances of Russian regions are analyzed.
The seven integrated power systems of Russia's unified power system.

The effects of the newly installed wind, solar, and hydroelectric power capacity on power generation became noticeable in 2018 when production of wind energy in Russia rose by 69.2%, and that from PV by 35.7%. Combined, wind and solar PV output crossed the 1 TWh threshold. 5
In Russia, the price of electricity is extremely low, and the grid is ubiquitous. Shifting mobility from internal combustion engine to electric vehicles therefore is an economically convenient opportunity starting from companies and cities operating large vehicle fleets.
