Ukraine's energy sector
Ukraine's energy sector is a complex landscape shaped by historical reliance on Soviet-era technologies and significant dependence on Russian energy imports. Before the 2022 invasion by Russia, Ukraine's energy mix primarily included coal, nuclear power, and natural gas, with nuclear energy generating about 55% of the country's electricity. The ongoing conflict has led to substantial destruction of energy infrastructure, compounding long-standing issues of inefficiency and outdated systems. With coal remaining an important source of energy, particularly from the Donetsk Basin, the war has disrupted its production and availability, prompting the government to seek alternative sources.
Ukraine has increasingly focused on energy independence, implementing policies aimed at improving efficiency and integrating renewable energy sources, which accounted for roughly 13% of energy production in 2022. The country is also a crucial transit hub for natural gas and oil flowing from Russia to the European Union, making its energy landscape of interest to European nations. Efforts to modernize energy infrastructure and reduce reliance on Russian imports have become vital in light of deteriorating relations. Despite the challenges posed by the conflict, Ukraine continues to engage in energy cooperation with the EU, underscoring its significance in broader European energy security discussions.

Ukraine's energy sector
Official Name: Ukraine.
Summary: Prior to Russia's invasion in 2022, Ukraine’s primary energy sources were domestically mined coal, nuclear power, and natural gas, with a heavy reliance on Russia for gas imports and nuclear fuel assemblies. As the war progressed, about half of Ukraine's power infrastructure was destroyed.
Ukraine’s energy sector has long been defined by Soviet-era technologies. Prior to Russia's 2022 invasion, Ukraine relied on Russian gas imports and nuclear fuel assemblies from Russia. Being one of the most energy-inefficient countries in the world and heavily dependent on foreign energy imports, post-Soviet Ukraine adopted a series of national policies to address energy efficiency, energy independence, and strategic investment in energy. Energy policies in the early twenty-first century added a focus on renewable energy, reducing environmental impact, and strengthening Ukraine’s position as a gas and oil transit country. Despite policies promoting renewable energy, Ukraine is largely powered by nuclear power, coal, and natural gas. Ukraine is also a key transit country, moving gas and oil from Russia to the European Union (EU), which has increased the EU’s interest in Ukraine’s energy sector, although the Russian invasion cast doubt on the future of the country's international energy commitments.
Nuclear Energy
Ukraine's fifteen nuclear reactors generated approximately 55 percent of the electricity consumed in Ukraine in 2022. The reactors in Ukraine are of Russian design, with an intended life span of thirty years; the older plants were granted operating extensions beyond this original limit. Although the reactors at Chernobyl were closed in the years following the infamous 1986 disaster, nuclear power remains key to achieving Ukraine’s energy security and energy independence goals. The largest nuclear power plant in Europe is in Ukraine, at Zaporozhye. Although nuclear power has come to a grinding halt in much of Europe in the aftermath of the Chernobyl accident, Ukraine completed two new nuclear reactors in 2004 and later announced an intent to continue building more to meet the increasing demand for energy. Following the Russian invasion of Ukraine, the Zaporozhye plant was captured by Russian forces in March 2022 but continued to operate.
Russia has long provided much of Ukraine’s nuclear fuel and services. Ukraine has uranium mines but lacks the capacity to refine uranium into nuclear fuel and has thus heavily relied on Russia to process raw uranium into fuel throughout the late twentieth and early twenty-first century. Ukraine began a series of processes in 2005 aimed at reducing its reliance on Russia that culminated in disconnecting Ukraine's nuclear reactors from the Russian power grid in February 2022. Ukrainian and European engineers later began the process to integrate the Ukrainian reactors into the European power grid in March 2022.
Coal
Until 1970, three-quarters of Ukraine’s electricity came from coal-fired thermal plants. The Donetsk Basin in eastern Ukraine has been mined since 1795 and contains nearly half of Ukraine’s coal reserves. With the introduction of nuclear power, the share of coal-generated power declined. Despite the decline in coal’s share of energy generation, it has remained an important fuel for Ukraine’s energy independence plans. (Coal provided 30 percent of Ukraine’s electricity in 2020).
Beginning in 2011, Ukraine implemented a plan to increase coal production as part of its energy security goals through a three-stage program to develop the coal industry. The first stage (2011–15) planned to close uncompetitive mines and privatize the 120 state-owned mines. The state-owned mines were notoriously inefficient, particularly when compared to the productivity of the twenty-nine privately owned mines. The expectation was that privatization would increase productivity. The second stage (2015–20) focused on the modernization of the mining sector by the new privatized owners. The third stage (2020–30) is focused on the stable growth of the coal industry.
Ukraine’s mining industry has become notorious for its lack of safety. Poor infrastructure and lax safety regulations have resulted in hundreds of deaths annually. Since 1991, more than 5,800 people have died in legal mining operations. The value of coal has caused illegal mining to become commonplace. Illegal mines lack safety equipment and are often mined at night to avoid detection. Some miners prefer illegal mining, because they are paid reliably, as working in state mines often meant delayed salaries, sometimes for months. Authorities have closed hundreds of illegal mines annually, but more are continuously dug. There is no reliable figure for how many people have died in illegal mining operations.
The Russian annexation of Crimea in 2014 and the resulting separatist movements in the Donbas region of Ukraine (which is home to the majority of coal deposits) has led to a drastically lower availability of coal in Ukraine. The 2022 Russian invasion further complicated the Ukrainian coal industry, as a large part of the fighting between Russia and Ukraine occurred in Ukraine's eastern regions. As a result, the Ukrainian government began seeking alternative sources in order to meet the demand for coal.
Oil and Gas
Once one of the top countries in terms of natural gas consumption, Ukraine's consumption of natural gas fell from 72.2 billion cubic meters in 2005 to 18.725 billion cubic meters in 2022 due to the war and measure previously taken to reduce its reliance on fuel. Natural gas is largely used to heat homes and water in the residential sector. In the commercial sector, it is used to produce steel and chemicals. Ukraine does have a domestic oil and gas industry, but much of its natural gas is imported from Russia. Some have argued that the inefficient infrastructure left over from the Soviet era has caused billions of dollars of wasted energy, and as a result the Ukrainian government has begun focusing on modernizing its infrastructure. Experts have asserted that improving the energy efficiency of buildings and district heating infrastructure could reduce dependence on Russian gas imports by as much as 25 percent, something the Ukrainian government has a vested interest in following the deterioration of Russo-Ukrainian relations that began in 2014.
Renewable Energy
Renewable energy technologies in Ukraine include solar, wind, hydropower, geothermal for heating, and fuels from biomass. The greatest potential for solar power was in the Crimean Peninsula prior to its annexation, where the first solar power station opened in 2011 and supplied power to 5,000 homes. Ukraine has installed wind turbines, but they have harnessed only a small fraction of its wind power potential. Hydropower has the most installed operating capacity of the renewable energy options, but contributed to only 2.4 percent of energy produced in 2010. Following Russia's invasion and a series of policy revisions and infrastructure upgrades, renewable energy accounted for about 13 percent of all energy produced in Ukraine in 2022.
Relationship with the EU
About 16 percent of all gas consumed in the EU transits through Ukraine, and thus Ukraine is considered to be an important intermediary for European countries that rely on Russian oil and natural gas. In 2011, Ukraine, with assistance from the EU, launched preliminary studies of the modernization of the Ukrainian gas transit system. The EU has a keen interest in ensuring the safety, reliability, and performance of the Ukrainian natural gas transit pipelines. A memorandum of understanding on energy, signed in 2005 between Ukraine and the EU, addresses the following five main energy issues for bilateral cooperation: (1) the safety of Ukrainian nuclear power plants, (2) integration of electricity and gas markets, (3) the security of energy supplies and the transit of oil and natural gas, (4) improving the safety and development of the coal sector, and (5) supporting energy efficiency and renewable energies in Ukraine. Cooperation in the energy sector between the EU and Ukraine, including financial investment and technical assistance from the EU to Ukraine, has continued to be an important component of Ukraine’s energy portfolio. Despite the Russian invasion, Ukraine continued to transport Russian oil through its pipelines into Europe. Then, in May 2022, Ukraine suspended the transportation of some of the Russian gas it conveys into Europe due to interference resulting from Russian occupation.
