[7] Some electricity infrastructure was destroyed in the Russo-Ukrainian War,[8][9] but wind farms, solar power and batteries are thought to be resilient because they are distributed.
In 2015 electricity production fell to about 146 TWh largely due to a fall in anthracite coal supplies caused by the War in Donbass.
[5][6] 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.
[16][17] 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.
[21] From 2022 the strikes targeted civilian areas beyond the battlefield, particularly critical power infrastructure,[22][23] which is considered a war crime.
[26] 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.
[27] Further waves struck Ukrainian infrastructure, killing and injuring many, and seriously affecting energy distribution across Ukraine and neighboring countries.
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.
[31] The UK Defense Ministry said the strikes were intended to demoralize the population and force the Ukrainian leadership to capitulate.
[41] In 2021, Ukraine's nuclear reactors produced 81 TWh — over 55% of its total electricity generation,[42] and the second-highest share in the world, behind only France.
[53] The IEA says that capacity limits on links from neighbouring countries should be increased,[54] and that more decentralised generation and batteries should be installed for energy security.
Second, consumer tariffs should be structured to incentivise efficient electricity consumption, the deployment of behind-the-meter DERs like rooftop solar and batteries, and the operation of these resources in ways that deliver system-wide benefits."
