Racibórz is a Polish town chosen for the retrofitting of an existing coal-based district heating system.
More than 90% of Poland’s energy supply is based on fossil fuel consumption, like Racibórz, a town with a population of 54,778 inhabitants.
The local community, local manufacturers and local authorities, are keen to fully replace coal in the near future with renewable energy-based district heating without any significant rise in energy costs.
Currently, heat generation units at the demo site include 3 coal boilers (type: WR-25). The total boilers power equals to 87.225 MW.
The challenge of the WEDISTRICT project will be to satisfy the requirements of the end-users by demonstrating both the economic impact and the energy and environmental effects of the new system. Since the district heating system is already present and functional, the biomass heat generation unit will be installed with addition of PV installation and other infrastructures like thermal storage tank and heat pump.
The demonstration will be a prime example for Polish district heating networks on how they can foster the energy transition, reducing air pollution and benefitting the local community.
Technologies planned for Kuźnia Raciborska demo site:
Biomass boilers, PV panels and a heat pump
The system will include an air source heat pump of 300 kW and thermal storage, which will be mostly operational during the summer period for domestic hot water (DHW) needs. Biomass boilers and PV panels installation will power the heat pump as main suppliers.
