Low Temperature District Heating

for the Baltic Sea Region

Efficient district heating (DH) systems are an important component in achieving sustainable energy supply structures and thus contribute to reduced energy waste and greenhouse gas (CO2) emissions in the Baltic Sea Region (BSR). Currently, most DH systems do not comply with increased energy efficiency standards and are often technically outdated. Therefore, they need to be upgraded and equipped with advanced system concepts and innovative technologies. By lowering the temperature in the DH grids, a substantial reduction of heat loss is possible.

The project “Low Temperature District Heating for the Baltic Sea Region” (LowTEMP) will make the district heating supply in the partner regions more sustainable and promote the installation of so-called 4th generation district heating networks. These systems are characterised by the transfer of lower temperature heat in optimally insulated pipes with reduced pipe dimensions. At the same time, multiple heat supply options are possible in these systems, i.e. the use of waste heat from industrial processes as well as renewable heat sources like geothermal and solar-thermal.

Within the LowTEMP project, 19 partners and 30 associated partners representing local, regional and national authorities, district heating suppliers, energy agencies, research institutions, and associations from nine BSR countries work together. Jointly, they will provide the DH stakeholders with expertise and tools on how to plan, finance, install and manage smart and sustainable DH systems.

The LowTEMP project is supported by the European Union (European Regional Development Fund & European Neighbourhood Instrument) in the frame of the Interreg Baltic Sea Region Programme 2014-2020.
