The KeepWarm project, funded under H2020 Energy Efficiency, worked to accelerate investments to retrofit existing inefficient heat networks, improve system operations, and switch to renewable energy and waste heat sources.
District heating currently represents 12% of heat supply in the European Union. Whilst modern systems can significantly contribute to a more efficient use of resources and the integration of renewable energy, some of the existing systems are still highly inefficient and heavily reliant on fossil fuels.
Thanks to the project activities, district heating retrofitting works started in sixteen pilot sites in in Austria, Croatia, Czech Republic, Latvia, and Slovenia. Two Contracting Parties of the Energy Community, Serbia and Ukraine, took also part in the project with pilot sites.
KeepWarm has also provided concrete recommendations to policy-makers for the development of National Energy and Climate Plans (NECP) in the seven target countries. At the same time, the project influenced the inclusion of district heating retrofitting into Sustainable Energy and Climate Action Plans and similar municipal plans in Jelgava (Latvia), Celje (Slovenia), and Zhytomyr ( Ukraine), as well as into regional planning in Styria (Austria).
The project facilitated knowledge transfer and exchange of experience through newly developed training resources (available in multiple languages) complemented with material from numerous sources, which are accessible in one hub: the KeepWarm Learning Centre.
Success stories from the pilot sites
In Priboj, Serbia, KeepWarm contributed to the decision to replace heating pipes and substations as well as fuel oil boilers with a wood chip plant, for a total investment amounting to EUR 7 million. The project is already contributing to local job creation.
In Croatia, the operators of the district heating system of Zaprešić decided to connect heating stations into a single network. The system will also integrate large-scale solar collectors’ field as well as solar collectors installed on the roof of one of the heating stations.
In Eibiswald, Austria, the KeepWarm project has supported the decision to invest EUR 7.2 million to rebuild a boiler house, install an exhaust gas recirculation to increase efficiency, and expand the grid to connect new customers.
Project partners have facilitated the new investment plan of the district heating company in Brno, Czech Republic. A modern distribution network running on hot water will replace 27 km of inefficient steam pipelines by 2023, reducing energy losses in the distribution from 18% to 6% and contributing to 664 TJ of primary energy savings every year.
