# Czech Republic energy and heating infrastructure transition > Live situation record from CLSTR: https://clstr.news/situations/czech-republic-energy-and-heating-infrastructure-transition > Updated: 2026-09-01T16:19:45.000Z. Sources: 2. Developments: 2. The Czech Republic is undergoing a broad modernization of its heating and energy infrastructure, transitioning away from coal-based power toward lower-emission technologies. At the Mělník III site, ČEZ is investing between 20 and 30 billion crowns to construct the nation’s largest combined-cycle gas-fired heat and power plant. This project, expected to be operational by 2029, aims to reduce emissions by over half while providing heat to approximately 250,000 households. Remaining coal operations at the site are slated to end by 2030. Similar modernization efforts are occurring in other regions. In Hodonín, ČEZ has received permits to replace coal facilities with gas boilers, cogeneration units, and biomass boilers. In Třebíč, TTS energo has secured approval for a multi-fuel boiler utilizing biomass and municipal waste. Additionally, Prague is planning an 18.25 billion CZK investment to transform its district heating system, including an energy center on Císařský ostrov that will use heat from treated wastewater. The city aims to eliminate fossil fuels from its heating system by 2040. ## Timeline ### 2026-09-01: Czech Republic heating infrastructure undergoes major modernization Czech heating infrastructure is undergoing major modernization, including ČEZ projects in Hodonín and a massive 18.25 billion CZK investment by Prague to transition toward wastewater-based heat and fossil-free 2 sources. https://clstr.news/cluster/czech-republic-heating-infrastructure-undergoes-major-modernization ### 2026-08-15: Mělník III site transitions from coal to gas-fired power The Czech Republic is transitioning the Mělník III site from coal to gas, with ČEZ investing up to 30 billion crowns to build a large combined-cycle plant by 2029. 2 sources. https://clstr.news/cluster/mlnk-iii-site-transitions-from-coal-to-gas-fired-power --- Cite as: Czech Republic energy and heating infrastructure transition.
