CROATIA

District heating counts around 10% of the overall heat supply in the country. There are around 13 district heating companies in 19 cities and towns, including the main district heating company is HEP-Toplinarstvo, subsidiary of national power company HEP, holding 85% of the market share. Current district heating systems in Croatia mainly belong to so called 2nd generation of district heating, using hot water with supply temperatures well above 100°C.

Natural gas is the main fuel for district heat, while around 80% of district heat was generated through combined heat and power. Bad condition of existing building stock as well as the distribution grid requires substantial retrofitting. Modernisation and expansion of district heating systems in set as one of the priorities for Croatian energy policy.

About KeepWarm

KeepWarm is an EU-funded project whose objective is to accelerate cost-effective investments in the modernisation of District Heating Systems (DHS). It brings together eleven project partners from a variety of relevant sectors (energy agencies, national DHS associations, agricultural chambers, research institutes, consultancies on energy efficiency and NGOs) across Central and Eastern Europe.
The aim of the initiative, launched in April 2018, is to modernise DHS around the whole region and reduce greenhouse gas emissions by improving system operations and promoting a switch to less-polluting sources, like renewables. The project partners strive to ensure that best practices for environmental-friendlier heating and cooling will be taken up across Europe, replicating KeepWarm’s approach in other countries and regions, even beyond the end of the project in September 2020.

Country project partner

The research group at the Power Engineering and Energy Management Chair at the University of Zagreb is leading in the field of sustainable development of energy in the region. Its main areas of research include energy planning and management, optimisation and sizing of energy systems, energy demand modelling and mapping, as well as sustainability of regions. For KeepWarm, UNIZAG FSB works on capacity building of DHS operators and support to pilot projects in Croatia.

REGEA is the energy agency for Croatia and the whole region. It provides information, education and promotion of good practice across the energy sector in support of development and implementation of national and regional energy plans and programmes. Moreover, it leads energy audits and certification, energy performance contracting and public private partnerships. For KeepWarm, REGEA will be supporting pilot projects in all countries, as well as the Croatian DHS pilots.
