District Energy in Slovenia

In 2017, heat production increased by 3.12% compared with the previous year and is 3.80 % above the average for the last 5 years. The number of households using District Heating also increased in 2017 by 5.75% compared with 2016.

Customers in the residential sector in Slovenia in 2017 use mainly Renewables (51.93 %) and Oil/Petroleum products (13.50 %) for space and warm water heating. These are followed by Natural gas and electricity, whose consumption has increased by 18.82 % and 2.99 % compared to 2015 figures.

District heating, which is used mainly for space heating has increased by 3.61 % and usage for water heating stayed the same compared with 2015. The main reason is that prices for oil & petroleum product have increased over the past two years. Compared with 2015, usage of heat pumps for space and water heating increased by 26.86 % (34.37 % increase for space heating and 15.71% warm water heating).

Renewables and Oil/Petroleum products are still the main energy source for space and warm water heating on small urban and non-urban areas, while in some larger urban areas customers use heat from existing district heating systems for space and warm water heating.

District Cooling is still a relatively new system for cooling buildings in Slovenia. The municipality of Velenje is the first and only municipality who decided to use a distribution network for

District Cooling in the residential and commercial sectors (in 2017 the only customers are from the commercial sector). Cooling power for distribution system is provided with 967 kWth absorption cooling unit, which uses hot water from the second largest District Heating system in Slovenia as an energy source

The percentage of electricity produced from CHP comparing to net electricity production in Slovenia in 2017 is 34.28% and is above the average of last five years (Average of last five years is 31,74%).

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 the smart energy systems concept.
