Zaporizhzhia thermal power station is a large non-nuclear thermal power plant (DRES) in the purpose-built city of Enerhodar in Ukraine that was built by the Soviet Union between 1971 and 1977. It is the most powerful thermal power station in Ukraine, with an installed capacity of 2,850 MWe. Its primary fuel is coal; it can also fire natural gas and fuel oil, [2] and has tank storage for these reserve fuels adjacent to the coal bunkers.

The plant has two 320-metre (1,050 ft) tall flue-gas stacks, which are among the tallest free-standing structures in Ukraine. [3] :61 The plant is not equipped with any flue gas desulphurization systems, but does use 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 an ash pond; coal ash from the boilers is delivered by pipe to the 135 hectare (333 acre) pond where it is disposed of.[ citation needed ]

The plant supplies power to the southern regions of Ukraine. [2] Some of the power is transmitted from its substation through the Enerhodar Dnipro Powerline Crossing to the north side of the Kakhovka Reservoir.

On 4 March 2022, the thermal plant and the adjacent Zaporizhzhia Nuclear Power Plant were captured by Russian forces during the 2022 Russian invasion of Ukraine. On 5 May 2022, the thermal power plant stopped operating after it ran out of coal, as it was unable to get further deliveries due to the invasion. [4]

Unit specifications

As of January 1, 2021, the installed capacity is 2,850 MW:

A third 800 MW unit (number 6) has been decommissioned.

A small 1 MW grid battery was added in 2021 to test grid services. [5]

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. [6]

A fossil fuel power station is a thermal power station which burns a fossil fuel, such as coal or natural gas, to produce electricity. Fossil fuel power stations have machinery to convert the heat energy of combustion into mechanical energy, which then operates an electrical generator. The prime mover may be a steam turbine, a gas turbine or, in small plants, a reciprocating gas engine. All plants use the energy extracted from the expansion of a hot gas, either steam or combustion gases. Although different energy conversion methods exist, all thermal power station conversion methods have their efficiency limited by the Carnot efficiency and therefore produce waste heat.

It is operated by Energoatom, who also operate Ukraine's other three nuclear power stations.

<span class="mw-page-title-main">Thermal power station</span> Power plant that generates electricity from heat energy

A thermal power station is a type of power station in which heat energy is converted to electrical energy. In a steam-generating cycle heat is used to boil water in a large pressure vessel to produce high-pressure steam, which drives a steam turbine connected to an electrical generator. The low-pressure exhaust from the turbine enters a steam condenser where it is cooled to produce hot condensate which is recycled to the heating process to generate more high pressure steam. This is known as a Rankine cycle.

It was situated on the south shore of the Firth of Forth, near the town of Cockenzie and Port Seton, 8 mi (13 km) east of the Scottish capital of Edinburgh. The station dominated the local coastline with its distinctive twin chimneys from 1967 until the chimneys' demolition in September 2015. Initially operated by the nationalised South of Scotland Electricity Board, it was operated by Scottish Power following the privatisation of the industry in 1991. In 2005 a WWF report named Cockenzie as the UK's least carbon-efficient power station, in terms of carbon dioxide released per unit of energy generated.

<span class="mw-page-title-main">Blyth Power Station</span>

Blyth Power Station refers to a pair of now demolished coal-fired power stations, which were located on the Northumberland coast in North East England. The two stations were built alongside each other on a site near Cambois in Northumberland, on the northern bank of the River Blyth, between its tidal estuary and the North Sea. The stations took their name from the town of Blyth on the opposite bank of the estuary. Blyth A Power Station was built and opened first but had a smaller generating capacity than its sister station, Blyth B Power Station, which was built to its west four years later. The power stations' four large chimneys were a landmark of the Northumberland skyline for over 40 years; the A Station's two chimneys each stood at 140 metres (460 ft); the B Station's two chimneys were taller, at 170 metres (560 ft) each.

Datteln Power Station is a modern coal-fired thermal power station in Datteln, Recklinghausen, 12 km north of Dortmund, North Rhine-Westphalia, Germany. It comprises four units with a total capacity of approximately 1,419 MW gross. Units 1-3 were built between 1964 and 1969 and were decommissioned in 2014. A characteristic of this power station is the fact that the most recently built unit, Unit 4, does not have a waste gas flue. Instead, the desulphurised flue gases are expelled using the updraught from the existing 180 m (590 ft) cooling tower. The power station is operated by Uniper.
