Power system for the next 10 years will still require thermal generation - Ukrenergo
The energy system of Ukraine to ensure its stable operation for the next 10 years will need thermal generation to cover the base and half-peak loads. This was announced on April 1, 2021, by Vitaliy Zaichenko, Director of the Integrated Power System of Ukraine - Chief Dispatcher of the NEC Ukrenergo, during an online meeting organized by the Energy Club.
“We anticipate that thermal generation in the power system will be present in the next 10 years in terms of base and half-peak loads. Unfortunately, it is not possible to make a power system that will be covered by green generation and nuclear generation in order to reduce nationwide carbon emissions," he said.
According to Zaichenko, renewable generation cannot provide sufficient electricity during peak periods (for example, at low temperatures in winter). Zaichenko gave an example that this winter, during some hours of peak load, generation from RES provided only 1 million kWh vise 500 million kWh needed for the national grid.
The Chief Dispatcher of NEC Ukrenergo also noted that Ukraine would still need 12 GW in TPP capacities. "It is necessary to have about 12 GW of power at thermal power plants as reserve," Zaichenko added.
He said that today the challenge for thermal generation is to implement the National Plan for Reduction of Emissions from Large Combustion Plants (NPRE).
According to the NPRE, during the heating period 2022-2023, some TPP capacity will be lost (due to the non-compliance to emissions requirement), which may lead to increased electricity imports.
