The Luhansk thermal power plant has been reconnected to the United Energy System of Ukraine by a 110-kW high-voltage line, DTEK Energo's press service has said.
The reconnection was carried out by DTEK Energo and Ukrenerho.
Because of limitations, the station cannot feed more than 50 MW into the grid.
"For now, we are generating little energy but we are ready to produce more to ensure the operation of six power units 200 MWh on condition of putting in place technical solutions to build a Kreminna-500 substation," DTEK Energo's generation director, Serhiy Kurilenko, said.
Since August 2014, DTEK's Luhansk thermal power plant has been the only energy generating facility in Luhansk Region, working autonomously from Ukraine's grid after power mains were damaged by shooting.
The Luhansk thermal power plant satisfies over 90 per cent of the region's demand for power. The plant gets its coal from DTEK's two mines in Russia, the company said.
