The largest source of district heating in the Czech Republic is abandoning coal in favour of low-emission fuels, potentially including biomass.
By 2030, the Mělník site, which supplies Prague, Mělník and Neratovice, will produce heat solely from low-emission sources and will help ČEZ Group, as well as Prague and other cities, to achieve their environmental goals. A quarter of the total CO2 emissions in the Czech Republic are generated from heat production.
The first step in the planned transformation is the shutdown of the largest coal-fired power plant to date, Mělník III. Its closure turns the plant into a pure heating supplier.
Simultaneously, the preparation of the construction of highly efficient steam gas sources has begun, with plans to employ other low-emission technologies in the future, such as biomass boilers, heat pumps, or equipment for the recovery of energy from waste. These sources will gradually replace the Mělník II and Mělník I lignite heating plants.
ČEZ plans to invest around CZK 30-40 billion (€1.75-1.56 billion) in transforming heating plants into low-emission sites in the coming years.
