Electricity in Ukraine

Electricity is an important part of energy in Ukraine. Most electricity generation is nuclear.[3] The bulk of Energoatom output is sold to the government's "guaranteed buyer" to keep prices more stable for domestic customers.[4][5] Zaporizhzhia is the largest nuclear power plant in Europe. Until the 2010s all of Ukraine's nuclear fuel came from Russia, but now most does not.[6]

Electricity generation by source

Some electricity infrastructure was destroyed in the Russo-Ukrainian War,[7][8] but wind farms and solar power are thought to be resilient because they are distributed.[9] As of 2024 about 2 GW can be imported from other European countries, but that is not enough to cover peak demand.[3][10] Better air defence is needed,[11]: 5  and many small gas-turbine generators are being installed to reduce the blackouts being caused by Russian attacks.[10]

History

edit

Electricity production fell from 296 TWh in 1991 to 171 TWh in 1999, then increased slowly to 195 TWh in 2007, before falling again.[12] In 2014, consumption was 134 TWh after transmission losses of 20 TWh, with peak demand at about 28 GWe. 8 TWh was exported to Europe. In 2015 electricity production fell to about 146 TWh largely due to a fall in anthracite coal supplies caused by the War in Donbass.[13][14]

In July 2019, a new wholesale energy market was launched, intended to bring real competition in the generation market and help future integration with Europe. The change was a prerequisite for receiving European Union assistance. It led to in increased price for industrial consumers of between 14% and 28% during July. The bulk of Energoatom output is sold to the government's "guaranteed buyer" to keep prices more stable for domestic customers.[4][5]

Grid synchronisation with Europe

edit
See also: Ukrenergo

Since 2017 Ukraine sought to divest itself of dependency on the Unified Power System of Russia (UPS) and instead connect westwards to the synchronous grid of Continental Europe, thereby participating in European electricity markets.[15][16] Power lines coupling the country to the grids of neighbouring Poland, Romania, Slovakia and Hungary existed, but were de-energised.

A necessary prerequisite of Ukrainian integration was for the country to successfully demonstrate it was capable of running in a islanded manner, maintaining satisfactory control of its own frequency. To do that would require disconnection from the UPS grid, and a date of 24 February 2022 was set. This proved to be the date Russia invaded Ukraine, but the disconnection nonetheless proceeded to schedule. Ukraine placed an urgent request to synchronise with the European grid to ENTSO-E, the European collective of transmission system operators of which it was a member, and on 16 March 2022 the western circuits were energised, bringing both Ukraine and Moldova, which is coupled to the Ukrainian grid, into the European synchronised grid.[17][18][19] On 16 March 2022 a trial synchronisation started of the Ukraine and Moldova grid with the European grid.[17]

War damage

edit
This section is an excerpt from Russian strikes against Ukrainian infrastructure (2022–present).[edit]
 
Fire at the Kharkiv TEC-5 power plant after a Russian missile strike on 11 September 2022.

Russia launched waves of missile and drone strikes against energy in Ukraine as part of its invasion.[20] From 2022 the strikes targeted civilian areas beyond the battlefield, particularly critical power infrastructure,[21][22] which is considered a war crime.[23][24] By mid-2024 the country only had a third of pre-war electricity generating capacity, and some gas distribution and district heating had been hit.[25]

On 10 October 2022 Russia attacked the power grid throughout Ukraine, including in Kyiv, with a wave of 84 cruise missiles and 24 suicide drones.[26] Further waves struck Ukrainian infrastructure, killing and injuring many, and seriously affecting energy distribution across Ukraine and neighboring countries. By 19 November, nearly half of the country's power grid was out of commission, and 10 million Ukrainians were without electricity, according to Ukrainian President Volodymyr Zelenskyy.[27] By mid-December, Russia had fired more than 1,000 missiles and drones at Ukraine's energy grid.[28] Several waves targeted Kyiv, including one on 16 May 2023 in which Ukraine said it had intercepted six Kinzhal missiles.

Deliberately depriving Ukrainians of electricity and heating during the cold winter months was the biggest attack on a nation's health since World War II.[29] The attacks on power stations inflicted large economic and practical costs on Ukraine.[30] The UK Defense Ministry said the strikes were intended to demoralize the population and force the Ukrainian leadership to capitulate.[31] This is widely deemed to have failed.[32][33]

The strikes were condemned internationally, with the European Commission describing them as "barbaric"[34] and NATO Secretary General Jens Stoltenberg calling them "horrific and indiscriminate".[35] President Zelenskyy described the strikes as "absolute evil" and "terrorism".[36] The International Criminal Court (ICC) indicted four Russian officials for war crimes connected with attacks against civilian infrastructure, including former Minister of Defence Sergei Shoigu and Chief of the General Staff Valery Gerasimov.

Generation

Ukrenergo has suggested that hundreds of small power plants should be built to enhance energy security.[11]

Nuclear

edit
This section is an excerpt from Nuclear power in Ukraine.[edit]
 
Rivne Nuclear Power Plant

Ukraine operates four nuclear power plants with 15 reactors located in Volhynia and South Ukraine.[37] The total installed nuclear power capacity is over 13 GWe, ranking 7th in the world in 2020.[38] Energoatom, a Ukrainian state enterprise, operates all four active nuclear power stations in Ukraine.[39] In 2019, nuclear power supplied over 20% of Ukraine's energy.[40]

In 2021, Ukraine's nuclear reactors produced 81 TWh — over 55% of its total electricity generation,[41] and the second-highest share in the world, behind only France. The Zaporizhzhia Nuclear Power Plant, the largest nuclear power plant in Europe, is in Ukraine.

The 1986 Chernobyl disaster in northern Ukraine was the world's most severe nuclear accident to date.

Lack of coal for Ukraine's coal-fired power stations due to the war in Donbas and a shut down of one of the six reactors of the Zaporizhzhia Nuclear Power Plant led to rolling blackouts throughout the country in December 2014. Due to the Russo-Ukrainian War, the nuclear power plant has been damaged.

Hydro

edit
This section is an excerpt from Hydroelectricity in Ukraine.[edit]
Hydropower is part of renewable energy in Ukraine. Ukraine is trying to build more small hydroelectric plants as sources of electricity in Ukraine.[42] State operating company is Ukrhydroenergo.[43] About half of hydro capacity of power stations in Ukraine has been destroyed by the war,[44] including the Kakhovka Hydroelectric Power Plant.[45] Defence against drones is important.[46]

Gas

edit

Many small gas-turbine generators are used, as these are more difficult to attack than large gas-fired or coal-fired power plants.[47] Up to 700 MW of gas peakers may be installed before 2030.[48]

Imports, storage, transmission and distribution

edit
 
Grid

About 2 GW can flow with neighbouring countries.[49] There is a 750kV link with Hungary.[1]: 6  It has been suggested that the 220kV link with Poland be improved and that interconnection with Slovakia be built sooner.[1]: 5  There are five 110kV interconnections with Moldova, but they could be better used.[1]: 5 

Due to the large share of nuclear balancing the grid is particularly difficult during peak demand, which is in the morning and evening due to retail demand.[50] Peak demand can reach 18 GW in winter, or 19 in cold winters.[50] DTEK is building more storage,[51] to improve ancillary services such as frequency control.[52] The IEA says that capacity limits on links from neighbouring countries should be increased, and that more decentralised generation and batteries should be installed for energy security.[53] They recommend more off-grid and mini-grid. Both transmission and distribution have been attacked,[53] and shelters have been built to protect substations from attack.[54][55] More storage is being installed.[56]

Economics

edit

In 2024 the price to householders was said to be about half the market price, and it has been suggested that to encourage energy saving and energy efficiency the subsidy should only apply to energy poor households and/or a certain minimum consumption.[57]

DTEK has started installing smart meters.[58] Central and city government is subsidizing rooftop solar installation.[50]
