The quick-start highly manoeuvrable generation, which can reduce the base capacity of thermal power plants, gives more space for the development of nuclear generation, which does not emit harmful CO2 emissions into the air, and also for the development of wind and solar power plants.
This was stated on 21 April during the International Conference “Wind Power Sector of Ukraine: Transition from “Green” Tariff to Market Conditions” by Volodymyr Kudrytskyi, the CEO of NPC Ukrenergo.
Today, the Ukrainian power system lacks flexible highly manoeuvrable generation as it is overloaded with base capacities of, for example, nuclear generation. Also now we must maintain throughout the day a certain base capacity of thermal power plants (TPPs) in the balance of electricity consumption/generation in order to be able to cover the evening peak of consumption. This increases the risks of RES curtailment during their peak production hours. The highly manoeuvrable generation would partly take the place of thermal power plants in covering consumption peaks and thereby would help reduce their base production during the day.
“The availability of new quick-start highly manoeuvrable capacities opens up opportunities for the construction of new wind farms in Ukraine without resorting to extensive constraints on their production. This concept forms the basis of our report on the assessment of resource adequacy (sufficiency) of generating capacities, which for 10 years to come describes what the power system will look like, what energy mix we expect, as well as what needs to be done to ensure the harmonious development of generating capacities,” said Volodymyr Kudrytskyi.
He emphasized that RES volumes have been increasing mainly due to the reduction of the thermal generation share. “This is certainly a positive trend, both from the point of view of ecology and from the point of view of the long-term cost of the energy mix. After all, marginal costs for renewable energy sources, aside from the “green” tariff, are very low, while for thermal power plants this indicator is the highest,” stressed the CEO of NPC Ukrenergo.
