Coal remains one of the defining features of Poland’s energy system, industrial history and regional economy. The country has reduced its dependence on coal considerably, but the fuel still supplied approximately half of Polish electricity in 2025. That places Poland well above most European Union countries and means that the decline of coal must be managed alongside the need to maintain reliable electricity supplies.
The Polish coal sector is not moving toward closure through one coordinated process. Hard coal mines, lignite mines and coal-fired power stations operate under different economic conditions and different retirement schedules. Some facilities may remain available for energy security even as they generate less electricity. Others are becoming difficult to operate because of declining deposits, rising production costs, carbon prices and the growth of renewable power.
Coal Still Sits at the Center of Poland’s Electricity System
Coal’s share of Polish electricity generation has fallen sharply from the levels recorded at the beginning of the century. Even so, it remains the country’s largest individual source of power. Hard coal and lignite plants continue to provide dispatchable generation that can operate when electricity demand is high or wind and solar output is low.
This role is particularly important because Poland is changing several parts of its power system at the same time. Wind and solar capacity are expanding, older coal plants are approaching retirement, electricity demand is expected to rise, and large nuclear projects will require many years to complete. Poland must therefore replace not only annual coal generation, but also the system services provided by conventional power stations.
Coal plants contribute controllable capacity, voltage support, system inertia and reserve power. These functions can increasingly be delivered by batteries, grid-forming renewable equipment, interconnection and flexible demand, but the required infrastructure is not yet available at the necessary scale.
The immediate question is therefore not whether coal use will decline. That process is already underway. The more difficult question is how quickly individual plants can close without creating shortages during periods of low renewable generation or high winter demand.
Hard Coal and Lignite Create Two Different Coal Industries
Poland’s coal sector is divided between underground hard coal mining and large lignite operations linked directly to nearby power stations.
Hard coal mining is concentrated mainly in Upper Silesia, with additional production in the Lublin region. The largest operators include Polska Grupa Górnicza, Południowy Koncern Węglowy, Węglokoks and Lubelski Węgiel Bogdanka. Hard coal is used in electricity generation, combined heat and power plants, district heating, industry and household heating, although demand in several of these markets is declining.
Much of the Silesian industry faces difficult geological and economic conditions. Mines are deep, labour-intensive and expensive to operate. Domestic coal can therefore cost more than imported material, even though imports create concerns about energy security and dependence on external suppliers.
Bogdanka is an important exception within the industry. Located in eastern Poland, it has generally operated with higher productivity and lower costs than many Silesian mines. Its strategy includes maintaining coal production while developing renewable energy, recycling and other raw-material activities. This gives the Lublin region a longer adjustment period than some older mining districts.
Lignite follows a different model. It is extracted from open-pit mines and transported directly to adjoining power stations because its high moisture content makes long-distance transport inefficient. The Bełchatów complex in central Poland has been the country’s largest lignite-based electricity source, while the Turów mine and power station operate near the borders with Germany and the Czech Republic.
These complexes are not only power plants and mines. They are integrated regional employers with transport systems, maintenance operations, engineering contractors and local tax relationships. Their eventual closure will therefore affect entire local economies.
The Economics of Coal Are Changing Faster Than the Official Calendar
Poland’s 2021 social agreement with mining unions provides a pathway for closing hard coal mines gradually, with the final operations scheduled to end in 2049. The agreement also includes severance payments, mining leave, public support and regional transition measures.
The date provides workers and communities with a long-term framework, but it does not guarantee that every mine will remain commercially active until its assigned closure year. Coal production is already falling, and individual mines may exhaust accessible deposits or become uneconomic earlier than planned.
Polish hard coal output declined again in 2025, while lignite production fell more sharply. This reflects lower coal-fired electricity generation, operational conditions at individual mines and the growing financial pressure on conventional energy.
The European Union Emissions Trading System has become one of the most important influences on coal-fired power economics. Generators must purchase allowances for their carbon dioxide emissions, which raises the operating cost of coal plants compared with renewable, nuclear and some gas-fired generation. Older units also face maintenance expenses and stricter environmental requirements.
Several Polish utilities have already retired or scheduled the closure of coal units that no longer have a clear commercial future. The remaining units may operate for fewer hours, supplying power during periods of high demand rather than running continuously throughout the year.
This creates a financial problem. Plants that are needed for reliability may not earn enough from electricity sales to remain available. Poland has consequently argued for capacity-support arrangements that would compensate conventional generators for maintaining dependable power, including after existing European rules limit support for high-emission plants.
Upper Silesia Makes the Coal Transition a Regional Development Test
The future of coal is especially important in Upper Silesia, where mining has shaped urban growth, employment, transport and industrial identity for generations. The number of mines has already fallen substantially, but tens of thousands of people remain employed directly in underground mining, with many more working in equipment manufacturing, construction, logistics and specialist services.
Closing a mine does not produce an immediate replacement economy. Mining jobs are often relatively well paid and concentrated in specific municipalities. New employment may appear in different locations, require different qualifications or offer different wage levels.
Transition policy must therefore extend beyond worker retraining. Former mine sites require environmental treatment, land ownership must be resolved, infrastructure may need to be modernized, and municipalities must replace revenue previously generated by mining activity.
Some post-mining land can support industrial parks, logistics centers, renewable projects, data facilities or residential development. Mine water may be used for heating, while former shafts and underground infrastructure may have energy-storage or geothermal applications. However, these projects require financing, local planning capacity and coordination between national authorities, regional governments and mine owners.
The Just Transition Fund provides financial support for Silesia and other affected areas, but successful redevelopment will depend on the quality of the projects rather than the size of the allocation alone.
Electricity Security Keeps Coal in the System
Poland cannot remove large amounts of coal capacity before replacement resources are ready. Renewable generation is expanding quickly, but new transmission lines, storage systems and flexible generation are required to use that power effectively.
Offshore wind in the Baltic Sea, onshore wind, solar generation, gas plants, batteries and stronger cross-border connections are all expected to reduce coal dependence. Poland is also developing its first commercial nuclear power program, although nuclear generation will not provide an immediate replacement for retiring coal stations.
The pace of coal closures will therefore be influenced by construction schedules elsewhere in the energy sector. Delays to transmission projects, nuclear plants, offshore wind farms or flexible generation could keep selected coal units operating longer. Faster deployment of storage and renewable capacity could reduce coal generation more quickly than existing plans suggest.
Poland’s transmission operator expects renewable energy to supply more than 60% of electricity generation by 2035. Reaching that level will fundamentally change the role of coal. Instead of supplying continuous baseload generation, remaining coal plants would increasingly function as reserve or seasonal capacity.
Poland’s Coal Outlook Depends on Replacement Capacity
Coal will continue to influence Poland’s power system and regional economy through the 2030s, but its long-term direction is clear. Production is declining, renewable generation is rising, and the cost of maintaining older mines and plants is becoming more difficult to justify.
The actual speed of the transition will not be determined by the 2049 mining date alone. It will depend on whether Poland completes new power generation, storage and transmission infrastructure before existing coal assets become unreliable or uneconomic. The central challenge is no longer preserving coal’s historic position. It is replacing its electricity, employment and system-security functions in an orderly way.
