Overview: Ljubljana is Slovenia’s capital and largest city. Its district heating network is also the largest in the country and a key asset for the city. The age of the network, however, starts to show its signs and needs for improvements, and a change in fuels used for heat generation is needed.

Current DH status: The city has an extensive district heating network of more than 270km of pipelines. One of the main challenges for the city is to decarbonise its grid since most of the energy used in it comes from coal and biomass. The total heat sold in 2023 was 979,213 MWh, of which 817,054 MWh was hot water and 162,159 MWh was steam

What work will ENABLE DHC do?: Plans for the future include shutting down the remaining coal-powered units and converting one of them to operate on biomass. There is also a plan to build a waste incineration plant, which will also be connected to the district heating system.
