Low Temperature District Heating

for the Baltic Sea Region

Thermopolis Ltd. together with 18 project partners from 9 countries forma partnership, that aims at promoting low temperature district heating in the Baltic Sea Countries. The LowTEMP -project, which is financed by Interreg BSR, was carrier out during the period of 1.10.2017-31.12.2020. LowTEMP 2.0, also financed by Interreg BSR, continues on this topic with a slightly smaller partnership. The project period for LowTEMP 2.0 is 1.1.2021-31.12.2021.

The focus of LowTEMP 2.0 is to put the training program created in the first project into use. The training material will be translated into national languages, including Finnish. Training events based on this material will be held during the fall of 2021.

In order to contribute to a reduction of energy waste and greenhouse gas emissions in the Baltic Sea Region (BSR), energy supply systems in all countries need to become much more efficient. Thereby, district heating (DH) infrastructures play an important role, but currently, existing DH systems do not comply with increased energy efficiency standards and often are technically outdated. Therefore, they need to be upgraded and technology has to change, i.e. present DH systems must undergo a change towards low temperature DH networks, supplying heat to new low energy buildings, but also to the existing building stock that has been or will be refurbished. Within the LowTEMP project, partners from nine BSR (Baltic Sea Region) countries come together, representing local and regional public authorities, DH (District Heating) providers, energy agencies, research institutions and national associations representing the energy and district heating sector. Together they aim to make the DH supply in their municipalities or regions, but also on a broader scale in other BSR regions, more sustainable by integrating Low Temperature District Heating (LTDH) solutions.


The project partners will jointly produce a knowledge platform on DH in the BSR, an assessment of the sustainability effects, business models and funding structures for LTDH, as well as a training programme to disseminate and promote the project know-how and improve the capacities of responsible stakeholders in the BSR. In addition, a central result will be pilot energy strategies that will be developed by the partner municipalities with support of the whole project consortium. Also, pilot testing measures will be realised, as first steps towards the reconstruction of the DH supply structure. LowTEMP will strongly contribute to increased awareness and know-how among the responsible public and private stakeholders in the BSR, on the necessity to promote a fast deployment of sustainable energy supply systems, that allow the use of renewable or waste heat and low temperature heat distribution. Through the LowTEMP project outputs, project partners and target groups will be equipped with guidelines, strategic approaches and solutions on how to integrate LTDH in their municipalities or regions. This shall lead to the implementation of concrete projects restructuring the existing DH systems towards future sustainable LTDH grids.

LowTEMP 2.0

LowTEMP 2.0 aims at the durability of the project results and the training programme. Within the main project a training programme on the planning, installation and management of LTDH systems (“LowTEMP training package”) is developed. The training programme contains key know-how and innovative strategies and tools to enable DH stakeholders to realise LTDH in the BSR. Project partners and selected stakeholders will test the training programme and at the same time be training as trainers. At the end of the regular project, i.e. after the training package has been developed, tested, revised and then published, it will be available on the project website for download. The training package will consist of teaching material (ppt-presentations), explanatory material for the trainers, templates for handouts, etc. To achieve this, the development of an e-learning tool will be the focus activity of the extension stage. The training material package will be translated into the nine BSR languages.
