In July 2026 Polish authorities advised households to purchase heating fuel—coal and wood—while demand was low, noting that coal prices ranged from about 1,150‑1,300 zł per tonne and wood prices were stable. Experts warned that prices could rise later in the season, making summer purchases advantageous. A few weeks later, an extreme heatwave lowered the Vistula River level, limiting cooling water for coal‑fired power stations. Operators at the Połaniec and Kozienice plants reduced output, cutting roughly 2,000 MW, while a major block at the Bełchatów plant was taken offline for a multi‑month overhaul. The combined reductions heightened strain on the national grid, highlighting emerging supply constraints as the summer progressed. By early August, wholesale electricity prices in Poland spiked above 2,200 zł/MWh during evening hours as the low Vistula flow continued to restrict cooling at coal plants. The government responded by convening a crisis mini‑staff to coordinate emergency measures. The same heatwave also forced nuclear reactors in several European countries to curtail output, underscoring the broader regional impact of river‑water shortages on energy security.
