ZNPP units 1 and 2 confirmed Energoatom’s right to enter the ancillary services market

Tests of Zaporizhzhya nuclear power plant units 1 and 2 confirmed compliance with the requirements of the Transmission System Code to obtain a certificate, entitling SE NNEGC «Energoatom» to enter the ancillary services market, the 

As a reminder, on April 16-17, 2021, specialists of SE NNEGC «Energoatom» and PJSC NPC Ukrenergo carried out tests of ZNPP power unit 2 for ancillary frequency maintenance reserve services provision to the transmission system operator in the amount of +/- 20 MW. On May 8-9 similar tests were conducted at ZNPP power unit 1.

 «Tests at power units 1 and 2 were carried out to confirm the feasible power reserve, which will be used to maintain the frequency in the power system,» said Deputy Chief Specialist for production organization – Deputy Head of production engineering service for energy market Dmytro Chaltsev. – «This is +/- 20 megawatts of current capacity in the range of 600 to 1000 megawatts. We have proved that we technically maintain this reserve, i.e. we meet the criteria of NPC Ukrenergo for the provision of this service.»

Thus, two ZNPP million-plus power units have confirmed their ability to provide the frequency maintenance reserve ancillary service. This is another step towards the integration of the Unified power system of Ukraine with the ENTSO-E European continental power system.

The rated primary frequency control mode should be implemented at all ZNPP power units by 2023. Under favourable conditions this year the appropriate tests at Zaporizhzhya nuclear power plant unit 4 are also planned to be carried out.
