Zaporizhzhia thermal power station

Zaporizhzhia DRES is a large thermal power plant (DRES) built by the Soviet Union at Enerhodar in Ukraine. The plant was built between 1971 and 1977. It has two 320-metre (1,050 ft) tall flue-gas stacks, which are among the tallest free-standing structures in Ukraine. On 4 March 2022, it was captured by Russian forces together with the adjacent Zaporizhzhia Nuclear Power Plant. It is the most powerful thermal power station in Ukraine with an installed capacity of 3,650MWe. Its primary fuel is coal however it can also fire natural gas and fuel oil and has tank storage located on-site for these reserve fuels adjacent to the coal bunkers.[1]

The Zaporizhzhia thermal plant is not equipped with any flue gas desulphurization systems, the plant does make use of electrostatic precipitators to remove fly ash prior to the flue gas being exhausted via one of the two chimneys. Like many other coal fired generating stations, the Zaporizhzhia site encompasses a 135 hectare (333 acre) coal ash pond where coal ash from the boilers is delivered by pipe to this pond where it will be disposed of.

Unlike the neighboring nuclear power station, which has transmission lines running on land in the opposite direction; the thermal power plant has transmission lines which run from the plants substation directly across the Dnieper river and distributes power to the southern regions of Ukraine. It helps to maintain a good energy balance with the adjacent NPP.[2]

Unit specifications

As of January 1, 2021, the installed capacity of DTEK Zaporizhzhya TPP is 3,650 MW:

  • 2 units of 300 MW each. 2.4 with CCI-312 boilers and K-300-240-2 turbines;
  • 2 units of 325 MW each. 1.3 with CCI-312 boilers and K-325-23.5 turbines;
  • 3 units of 800 MW each. 5.7 with boilers TGMP-204 / A and turbines K-800-240-3 are in conservation

A small 1 MW grid battery was added in 2021 to test grid services.[3]

2021 accident

On February 3, 2021, the entire city of Enerhodar, as well as several neighboring towns lost power. This was caused by an accident at the Zaporizhzhia thermal power station, where, according to the officials, power output of the plants units dropped to zero.

According to Centrenergo, the plant's operator:

The accident was caused by an emergency shutdown of power unit No. 1 of Zaporizhzhya thermal power plant and No. 9 of Kurakhovskaya thermal power plant due to damage to the heating surface of the boiler unit. Now the power engineers are eliminating the violations and after the repair they promise to resume the operation of the energy system. Such a technological disruption is not uncommon for any thermal generation, especially during periods of high load.

In order to balance the system, power unit No. 10 of the Krivorozhskaya TPP was taken out of repair ahead of schedule. In addition, at the command of NEC Ukrenergo, power units No. 9 and 12 of Burshtynskaya TPP and No. 7 of Dobrotvorskaya TPP were synchronized to the grid and began supplying power.[4]
