Power unit No.3 of RNPP will be put into reserve due to balance restrictions – Energoatom

Due to balance restrictions in the power system, nuclear power units are forced to operate at reduced power or are in reserve. This was reported by the press service of Energoatom.

In the current month, from April 1 to April 18, 2020, the reserve capacity of nuclear power plants ranged from 333 to 997 MW, on April 19 it reached 1,432 MW, and during April 19-20 (Easter holidays) it reached 2150 MW.

It is noted that 8 out of 11 operating power units operated at reduced power (the smallest load of ZNPP-1 is 521 MW of the existing 1000 MW).

As of April 23, 2020, 15 nuclear power units are in operation, of which:

  • in a state of preventive maintenance – 3 power units and a TG-3 turbogenerator at RNPP-2 – with a total capacity of 3220 MW;
  • is in reserve - 1 power unit with a capacity of 1000 MW (ZAES-2 was put into reserve on April 21, 2020 due to the balance restriction on the part of the power system)
  • in the state “work at power” - 11 power units. At the same time, the actual load of operating power units is 8305 MW.

The total reserve of nuclear power plants is not used now through balance restrictions - 1730 MW.

“Taking into account the information provided by NEC“ Ukrenergo ”about the forecast increase in the balance sheet limitations of NPP capacity at the end of April, in order to reduce the negative consequences for the equipment of NPP power units from operation at low power, it is planned to additionally put into reserve a power unit No. 3 of the RAES (1000 MW) after the planned completion repair and connection to the TG-3 network of RNPP-2 power unit,” the company said.

Thus, over the next two months 2 power units at Ukrainian nuclear power plants with a total capacity of 2,000 MW will be in a forced outage.

The company notes that limiting the available capacity of nuclear power units (the cheapest electricity for all types of generation) will automatically lead to an increase in the share in the overall balance of more expensive types of generation (thermal and renewable energy), which will generally negatively affect the level of electricity prices .

Recall, on April 21, Energoatom turned off power unit No.2 of Zaporizhzhia NPP due to balance restrictions in the power system.
