Prague City Councillors have approved the preparation of the construction of an Energocentre, which will process waste heat from the Central Wastewater Treatment Plant on Císařský ostrov. The first step will be to secure documentation for a zoning decision. In the first stage, the Energocentrum could supply a total of approximately 1,660,000 GJ of heat per year and supply more than 41,000 households. It could be operational by 2030.

The capital is looking for alternative, clean energy sources. "Energy security and self-sufficiency are our priority. For a long time we have not exploited the potential of water in Prague, the wastewater flowing to the treatment plant has a relatively high temperature due to the significant consumption of hot water. And this treated wastewater has a significant potential to be a source of thermal energy, primarily for heating. Their use can contribute significantly to reducing dependence on natural gas and to reducing the carbon footprint of heating systems in the capital city of Prague. And I think the number of households and inhabitants of Prague that the Energocentrum will supply is also telling - in the end it will be almost a hundred thousand people," says Prague Mayor Bohuslav Svoboda. It is expected that the Energocentrum will contribute to a significant saving of natural gas (up to 14.6 million m3/year or 29.2 million m3/year) and a corresponding reduction in the carbon footprint of heating. The use of low-potential waste heat from the WWTP is also one of the priority measures listed in the Prague City Climate Plan 2030.
