Rybnik

Rybnik is trying to rewire a coal city without letting the heat go out. The city's own report says that roughly three-quarters of household heat still comes from coal even as officials pour public money into ripping old systems out. Better known as a Silesian mining center, Rybnik sits 233 metres above sea level and had 124,784 registered residents at the end of 2023, far below the older GeoNames count. It remains the largest city in the Rybnik Agglomeration, but the population has been slipping by a few hundred people a year.

The underappreciated fact is that Rybnik's real bottleneck is not electricity generation alone. It is metabolic continuity: how to keep homes warm, jobs intact, and air breathable while dismantling the fuel system that built the city. The 2023 city report says about 43% of residents still relied on individual coal heating and about 32% on coal-fed district heat. Yet by January 14, 2026 the city's clean-air page reported 7,441 subsidy applications, 5,852 completed projects, and PLN 77.69 million in paid-out grants. The same municipal report describes a move toward dispersed gas heat sources after earlier plans tied to the power plant stalled.

At the regional scale, the shift is even larger. PGE says the conventional units of Elektrownia Rybnik are due to stop energy production by the end of 2025, with heat continuity measures running into 2026, while a new gas unit of about 880 MW is being built nearby for roughly PLN 3.7 billion. That is autophagy under political pressure: the city and its utilities are digesting parts of the old coal body to keep the wider organism alive. Homeostasis matters because a winter heat failure would be existential, and phase transition matters because once enough boilers, district links, and generation assets switch fuel, Rybnik stops being a coal system with green add-ons and becomes something else.

Biologically Rybnik resembles lichen, one of the classic indicators of air quality. When the environment is dirty, lichen disappears first; when it returns, you know the substrate has changed.
