Poland halves coal's share of electricity as solar drives July low

Yearly power is still just over half coal, the grid built for big central plants is curtailing wind and solar and refusing connections, and the plan to replace baseload coal hinges on a contested nuclear build already three years behind schedule.

What happenedCoal dropped to about 53.5% of Poland's electricity in a sunny July 2026, down from about 92% when Poland joined the EU, but yearly data still shows just over half coal and the July share is so far via press citing the grid operator, not yet in its published monthly totals.

Why it mattersIt shows if Europe's most coal-dependent power system can quit coal without blackouts or abandoning Silesia, where mining jobs are nationally small but locally concentrated — a test for other coal-heavy economies and for EU energy costs.

Still openWhether summer solar peaks become a lasting annual shift, and whether a €42bn nuclear programme and €15bn grid upgrade can provide baseload and flexibility before the 5GW Bełchatów lignite plant closes in the mid-2030s.

Poland the European Union's most coal-dependent power system made about 53.5% of its electricity from coal in July 2026, down from about 92-94% when it joined the EU in 2004. That is a halving in a generation, but it was a sunny summer month, not a full year. The annual average is still just over half coal, and whether a July dip becomes a permanent crossing depends less on adding more solar than on whether a strained grid and a contested Bbn nuclear plan can replace the country's biggest coal plant before it closes.

The gap between month and year is the story. In July, hard coal was 35.3% and lignite, the cheaper brown coal, was 18.2%, for 53.5% coal in total, while renewables were roughly 38% to 42% depending on how they are counted, with about 21% solar and 15% wind. The year as a whole is cooler: coal was 59% in 2023, 56.2% in 2024 and 52.7% in 2025, while renewables were 29.4% in 2024 and 31.4% in 2025. June 2025 was the first month ever when renewables (45.6%) edged above coal (42.3%), yet the year still ended majority-coal. At 666 grams of CO2 per kilowatt-hour, Poland remains the EU's most carbon-intensive grid, against an EU average of 251 grams.

The July shares also have a checkability limit. Poland's state-owned transmission operator PSE, which runs the high-voltage grid and publishes generation data, reports annual capacity 77,331 megawatts at the end of 2025, up from 72,188 a year earlier, with wind and other renewables at 37,106 megawatts and large thermal plants at 37,794 megawatts but its own monthly totals in terawatt-hours for July 2026 were not yet published on 13 August 2026. The July percentages are therefore via Polish business press citing PSE. The direction is real a fall of about 30 points in a decade but the absolute scale of that July is not yet verified in PSE's monthly data.

Demand did not push coal out. Poland used about 154 terawatt-hours in 2024 and is expected to need 210 to 230 by 2040 as heating, transport and industry electrify. Three things overlapped to make coal expensive and solar cheap at the same time.

First, the EU Emissions Trading System, the EU-wide market where power plants buy a permit for each tonne of CO2 they emit. By 2025 carbon made up 63% of the short-run cost of hard coal about p of a 0 per megawatt-hour cost on the domestic coal price tracked by analysts at Modo Energy, up from 43% in 2020. Coal still sets the price in most hours, but it does so while losing money. That 63% is one methodology's snapshot; cheaper panels and EU-funded grid work moved in parallel, so no single cause can be isolated.

Second, a rooftop boom. Households and businesses that both produce and sell power so-called prosumers reached 1.5 million micro-installations totalling 12.7 gigawatts by the end of 2024, within 24.8 gigawatts of total solar by end-2025, plus about 10.5 gigawatts of wind. Renewables are now more than half of installed capacity at 37.8 gigawatts, even though they are only about 30% of generation because wind and solar run fewer hours than coal.

Third, EU money for wires. Between 2004 and 2024 Poland obtained more than 55bn Polish zloty from the EU for energy transformation, according to Trade.gov.pl summarising a Polish Economic Institute report. The report says those funds helped modernise or build 1,977 km of extra-high-voltage lines 12.3% of that network and 1,391 km of heating network, alongside building upgrades and onshore wind. In 2004, 94% of electricity came from hard coal and lignite and 3% from renewables; by 2023 coal was 59% and renewables 27%.

More solar has not meant linearly less coal because the grid was built for a handful of big coal plants in the centre, not millions of rooftops and coastal wind farms. Ordered turn-downs of wind and solar when the grid cannot take them curtailment were 731 gigawatt-hours in 2024, about 2% of variable renewable potential, and nearly doubled to about 1.4 terawatt-hours by July 2025. Hours when generators pay to stay online negative day-ahead prices ran 300 to 400 hours in 2025, roughly twice 2024, with a low of -528 zloty per megawatt-hour in June 2025. PSE refused 74 gigawatts of connection requests in 2024, more than the entire 72-gigawatt system.

Storage cannot yet smooth this. Poland has about 1.7 gigawatts of pumped hydro and only megawatts of batteries against 33.5 gigawatts of renewable capacity, so summer surplus and winter lulls persist a 10-day wind-and-solar lull in November 2024 pushed prices to c0 per megawatt-hour. PSE plans to spend about bn between 2025 and 2034 to accommodate 18 gigawatts of offshore wind plus 19 gigawatts onshore and 45 gigawatts of solar, within a wider e0-670bn transition need to 2040. That is a target, not delivered capacity, and system costs already more than double the cost of solar alone once curtailment and balancing are included. Flexible gas, which can start in 5-10 minutes versus 80-150 minutes for coal, is part of the bridge, but Warsaw does not want it as long-term baseload.

The long-term baseload answer is meant to be nuclear, to replace Be42chatw in central Poland Europe's largest lignite plant at 5.1 to 5.3 gigawatts, supplying 20-25% of national demand when running flat out, due to close in the mid-2030s. The wider coal fleet is set to shrink from 26.5 gigawatts today to 8.7 gigawatts by 2049, with 18 gigawatts already holding a retirement date.

Poland's Energy Policy until 2040 envisages 6 to 9 gigawatts of nuclear. The first plant, at Lubiatowo-Kopalino on the Baltic coast, is three AP1000 reactors Westinghouse's large pressurised-water design totalling 3.75 gigawatts, built by the Westinghouse-Bechtel consortium and owned by the 100% state-owned company Polskie Elektrownie Jdrowe (PEJ). On 31 March 2026 PEJ filed a construction licence application with Poland's National Atomic Energy Agency (PAA) the first such application in post-1989 Poland of more than 40,000 pages prepared by over 200 experts. The regulator has 24 months to decide, not counting time for PEJ to supplement the file. PEJ plans to seek a building permit in 2027, pour first nuclear concrete in late 2028, and bring units online in 2036, 2037 and 2038 three years later than the original 2033 target, in line with a global average delay of about three years.

The price tag is B-45bn, or 192bn zloty. Financing is 30% equity 60.2bn zloty from the state budget between 2025 and 2030 plus 70% debt via export credit agencies in the US, Canada and France, with state guarantees on all the debt. Revenue support is a two-way Contract for Difference, a 40-year government contract that guarantees a fixed strike price and makes consumers or the budget pay the difference to the market price. The European Commission approved the aid on 9 December 2025 under EU state-aid rules, case SA.109707, after an in-depth investigation opened in December 2024. Available summaries say the Commission cut the contract from 60 to 40 years, required the strike price to be set by a model limited to the funding gap, imposed profit-sharing and periodic cost reviews, and conditioned approval on PEJ remaining legally and functionally independent and on at least 70% of annual output being sold on the open power exchange.

What that strike price will be is not disclosed in the available summaries. Poland's December 2024 notification, as reported in Polish press, put it at 470-550 zloty per megawatt-hour in real terms, about 0-130, assuming the plant runs 92.7% of the time and costs 192bn zloty to build above the 2026 forward price of about 459 zloty and comparable to offshore wind caps of 485-512 zloty. The same filings show it is sensitive to overruns, delays and currency moves: a 30% cut in build cost would lower it to 400-480 zloty, a 40% overrun would raise it to 600-680 zloty, with similar rises for a three-year delay or a 20% zloty depreciation. Those are reported ranges, not a settled price. A second plant to reach 6-9 gigawatts is planned with a technology partner to be chosen in 2027 and a site confirmed in 2028, preferably reusing coal infrastructure at Be42chatw and Konin in central Poland, with Kozienice and Po42aniec as alternatives, for construction around 2032 and operation in 2040-42. That schedule is likely, not confirmed.

Nationally, coal is now small less than 2% of employment. Locally, it is still everything. Direct jobs fell from about 390,000 in 1990 to about 78,500 in Silesia and 88,000 nationally in 2020-22, plus about 21,000 indirect jobs in Silesia; the exact figure moves with whether lignite and contractors are counted. In some Silesian districts, up to 20% of the working-age population depends on mining, and 70% of 1,054 contractors depend on a single mine. Eighty percent of contract value stays within 20 km in Silesia.

The Social Contract Umowa Spo42eczna signed on 28 May 2021 in Katowice after nine months and more than 20 meetings between the government, Silesian authorities, mining communes and unions, tries to stretch that pain to 2049. It sets a mine-by-mine closure schedule through the end of 2049 and guarantees employment until pension for those employed on 25 September 2020, with a social package written into law on 1 October 2021: mining leave up to four years at 80% of salary for those who can retire before 1 January 2028, processing-plant leave up to three years at 80% before 1 January 2027, a one-off severance of 120,000 zloty net, an allocation system moving workers from closing to operating units, and free retraining. The 31,000 zloty severance figure still circulating is outdated. Take-up is low in qualitative terms miners resist wage cuts of more than 250 zloty and shun solar and wind jobs and demography complicates the picture: Silesia's population fell 4.4% between 2000 and 2017, so some districts face labour shortages rather than mass unemployment. The EU's Just Transition Fund has earmarked 2.4bn for Silesia, but past transitions are sobering: a 1998 package cut 102,600 jobs yet left Silesian unemployment at 17.4% in 2003.

Both bets nuclear and 2049 are contested, and the serious arguments run both ways. The government and Commission case is that 6-9 gigawatts of nuclear is necessary baseload, that the aid is proportionate and market-compatible, and that the project is on track. The energy think tank Ember notes Poland cut coal from 91% to 51% in 20 years while growing GDP, making it a relatable model for other coal-heavy economies, and Warsaw has already fully exited Russian coal and gas 0% in 2024 versus 52% gas dependence in 2015 via the winoujcie LNG terminal and Baltic Pipe, albeit at a 112bn zloty fossil import bill in 2024.

The counter-cases are documented. On nuclear, a June 2024 finance study for Greenpeace by researchers at Copenhagen Business School and TU Berlin finds nuclear systematically suffers overruns, delays and reliability problems, leaving private investor appetite low, with profitability requiring heavy de-risking where taxpayers and ratepayers bear risk while liability, decommissioning and waste costs are typically excluded from initial calculations. Campaigners call it a black hole for taxpayers when wind and solar are already cheaper and falling. The Commission itself doubted proportionality, which is why it cut the contract to 40 years and imposed the 70% exchange-sale rule. Consumer advocates note the reported strike price sits above market forwards and offshore wind caps and is highly sensitive to overruns, delays and currency moves, with the cost ultimately levied via bills or the budget.

On 2049, unions, analysts and courts pull in opposite directions. Solidarity, the main mining union, says the deal liquidates a strategic industry; about 5,000 miners and energy workers protested in Warsaw on 9 January 2025 against closures of Rybnik in 2027, Dolna Odra in 2025 and 41aziska in 2028, with banners reading "Polish coal, Polish electricity," after 7,000-10,000 protested in 2021 over job guarantees. Energy analysts are blunt the other way: Forum Energii analyst Aleksandra Gawlikowska-Fyk said "2049 is far too late. Everybody knows there won't be place for coal in 2049," Ember analyst Dave Jones called continued subsidies 9bn zloty in 2025, about 600 zloty per household or 10% of personal income tax revenue, with mining costs above 900 zloty per tonne versus about 148 zloty in the US the most blatant fossil fuel subsidy and a blank cheque, and the Polish policy research firm Polityka Insight called the contract a tactical ceasefire, expecting hard-coal mines to close within 15 years. Poland is the only EU state without a coal phase-out date and, as of October 2025, the only state that had not submitted its final National Energy and Climate Plan due in June 2024, prompting Commission infringement action; its draft envisages coal at 0-4.8% by 2040. In court, the environmental law group ClientEarth sued PGE GiEK in September 2019 to close 11 of 12 Be42chatw units by 2030 and the last by 2035; on 22 September 2020 the District Court in 41d ordered negotiation within three months, with the judge stating the climate crisis is real and must be acted on the first such finding in a Polish court.

Poland has therefore done something real and something seasonal at once. It has halved coal's share in a generation without cutting demand, driven by carbon pricing, cheaper panels and turbines, and EU-funded wires. It has not yet made a majority non-coal year, its grid cannot yet absorb the renewables it has, and its plan to replace Be42chatw hinges on a nuclear build whose price consumers will pay and whose schedule has already slipped three years, while Silesia is promised jobs until 2049 that analysts, unions and judges all say will not hold as written. Whether July's 53% becomes an annual 49% will be decided less by another record solar month than by whether the grid and the reactors arrive before the coal plants leave.

How this piece is framed: The seasonal peak vs the structural shift: Poland's generational coal decline is real, but July's 53% is a solar-driven low — the binding story is what drove it, what now blocks it (grid + concentrated jobs), and what Poland is betting to replace baseload coal (a contested €42bn nuclear build).
