KYIV, Nov 22 – Ukrenergo is discussing with ENTSO-E (the European Network of Transmission System Operators for Electricity) the options for the operation of the Ukrainian energy system in an isolated mode, considering as a basic option the system functioning in such a mode for two weeks, chief dispatcher of Ukrenergo Vitaliy Zaichenko said.

"Preliminary agreements with ENTSO-E stipulate that work in an isolated mode can be as follows: week in winter, week in summer [during the peak periods] ... This weekly regime needs to be planned in detail to ensure sufficient power reserves in the power system," he said during the discussion of the report on the assessment of conformity (adequacy) of generating capacities for 2019 in Kyiv.
