In 2015 Russia carried out the electricity supply to the occupied Donbas, - reported Ukrenergo.
“Antratzit and Krasnodon power units supply as well as part of the Alchevsk and Luhansk cities supply was carried out by the Unified Energy System of Russia” – said in Ukrenergo statement.
Earlier OSCE observers stated about escalation of tension in Donbas
Also the source notes that Luhansk TPP had been working for a balanced load during 2015 year. The emergency shutdown of its units, equipment damage or significant increase in power consumption leads to current frequency reduction and triggers automatic frequency unloading.
Earlier, "Ukrenergo" announced that Ukraine continues to supply electricity to the occupied part of the Donbas.
