  • Ukrenergo will test another power unit at Zaporizhia NPP to participate in the ancillary services market

    NPC Ukrenergo plans to test Unit 1 of Zaporizhia NPP (ZNPP) on 8–9 May 2021 for certification for the provision of ancillary services (AS) – the frequency containment reserve (FCR). The reserve volume to be tested is  ±20 MW.

    In preparation for the event, an online meeting was held on 7 May between Volodymyr Kudrytskyi, CEO of NPC Ukrenergo, Yurii Sheyko, Acting First Vice-President – Technical Director of NNEGC Energoatom, Stephen Burns, Chief Director of Energy and Infrastructure bureau for Europe and Eurasia at USAID, Dean White, ESP Chief of Party at USAID, Sukru Bogut, Senior Energy Advisor at USAID Ukraine, and the World Bank representatives.

    The participants during a live broadcast from Zaporizhia NPP discussed the test preparatory process and associated activities directly with the experts who will perform the tests.

    “Energoatom’s entry into the ancillary services market is a strategically important event that opens a new stage in the development of the electricity market as a whole. The presence of nuclear power plants in the market will facilitate better flexibility of our power system, which is one of the main tasks of Ukrenergo as a transmission system operator. It will also increase competition between market participants who can provide this type of service. That is why we truly appreciate the assistance of the USAID Energy Security Project and the significant support they provide to Ukrenergo during the process of producers certification,” said Volodymyr Kudrytskyi, CEO of NPC Ukrenergo.

    The specific feature of Ukrainian nuclear power plants is that they are designed to operate in the basic mode. They cannot quickly change the generating capacity by a significant amount, which means they are not designed to be flexible. At the same time, the turbine governor at the NPP power unit makes it possible to increase or decrease its speed in a short time and change the generating capacity within ±2% (20 MW) of the nominal capacity (1,000 MW).  Such changes are safe and comply with the regulations on nuclear safety and operation of nuclear power plants in general.

    Earlier, on 17–18 April 2021, Ukrenergo already tested ZNPP Unit 2 for certification for the FRC provision in the volume of ±20 MW. The results obtained are being processed to determine the generating unit readiness to provide the service in accordance with the requirements of the Transmission System Code.

    In the IPS of Ukraine bidding zone, where NNEGC Energoatom operates, as of the end of April, the total volume of certified FRC is ±177 MW, which can be provided by 5 power plants. It should be recalled that ensuring a sufficient level of reserves in the power system is one of the key requirements for the integration of the Integrated Power System of Ukraine into the Continental European network ENTSO-E.
