District Energy in Slovenia

  • Country Profiles
  • 01 May 2017

 

In Slovenia, the number of households using district heating has significantly decreased in 2015 by 14.7% compared with the year before. The main reason is yearly increasing usage of heat pumps (geothermal & solar source). Compared with 2013, usage of heat pumps for space and warm water heating increased by almost 31.5%.

 

As shown in the graph below, the share of district heating accounts for 9% in 2015. More than half of all residential customers in Slovenia use renewables and approximately 16% is supplied by oil/petroleum products for space and warm water heating. In the third place is still natural gas with 11%. Within district heating, 89% come from recycled heat, whereas direct renewables only account for approximately 3%.

 

 

Regarding the role of CHP in Slovenia, 31.7% of the total electricity was generated by cogeneration. Within district heating, the share of CHP was almost 82% in 2015.

 

District cooling is a relatively new technology in Slovenia with a installed capacity of 4.9 MWth by 2015. The largest district cooling distribution network for the industrial sector is based in the municipality of Kranj, with an average annual production of 1,400 MWh of cooling energy. In the last few years, the majority of investments and projects have literally stopped due to the economic crisis, with only necessary maintenance investment in distribution systems being carried out.

 

The new Energy Concept of Slovenia (EKS) should be ready by the end of 2017. In the EKS, district heating and cooling systems will play an important role in achieving the EU 2050 energy goals, especially in urban areas with the implementation of smart energy systems.
