The rebuilding of the plant was completed in 1953. The installed capacity at the time was 38 MW.

In 1957, a concept was developed of supplying Pruszków with district heating. Two years later, the operations of the plant were expanded and a combined heat and power plant was established. A series of upgrades and renovations made it possible for the plant to operate efficiently for over 100 years, producing heat for the residents of Pruszków, Piastów, and the Michałowice commune. Electricity is transmitted to the national grid.

The company’s district heating system is currently 70 km long, which enables it to ensure year-round and secure supplies of heat. Water for filling the district heating system is prepared in a modern reverse osmosis station.
