The feasibility study Renewable Power-to-Heat in Hajnówka demonstrates that converting the coal-based district heating system of Hajnówka, Poland, to large heat pumps powered by renewable energy is technically feasible, economically viable, and environmentally beneficial. The switch would reduce CO2 emissions by 84%, cutting GHG emissions by 22-24 tonnes annually. Despite initial investment costs of around €25 million, the project promises stable heat prices and significant long-term savings. The success has inspired similar initiatives, including a follow-up project in Bitola, North Macedonia.
