In the small Slovenian town Kuzma a district heating network is established based on biomass burning. The investments were made by a private company, with the financial support of the national government, and the aim of reducing energy prices in the area. The biomass used is collected from local wood owners in the neighbourhood and converted into heat by two biomass boilers. In combination with a 10 m3 storage tank for peak load no additional heat source is required to supply heating to 58 houses and some other residential buildings.

District heating in Kuzma is a private investment of a local company. The motivation was a poor local situation regarding individual heating: Extensive use of wood biomass in old inefficient stoves for individual heating resulted in high biomass demand and poor air quality in winter. In addition, much heating oil was needed for individual heating and heating of larger objects (municipality building, school), which was at the date of erecting of the plant in 2012 very expensive (around 1 EUR/l).

The private initiative had a positive non-financial support in the municipality and from the local community, providing help in administrative procedures and acquiring of required documentation. The local community has been very positive regarding the intention of the investor to purchase biomass from local suppliers. The project also received national financial support in terms of a grant within the national scheme for support of wood biomass DH. The project is a lighthouse project in north-eastern Slovenia where there are no small renewable district heating systems.

The production of heat is based on two biomass boilers of the producer Fröling, including a 10 m3 heat storage which covers peak heat demand. No additional heat production using other resources is installed. Heat consumers are connected via a 1.5 km district heating network and Giaflex substations.

The private investor is purchasing biomass from local wood owners. At present time the offer of biomass exceeds consumption of approximately 2.000 m3 of wood chips, so the investor is also processing biomass and selling it to third parties – mainly to individual consumers within the radius of 40 km. The biomass is purchased in a radius of 40 km.

The overall investment amounts to 800,000 EUR. The investment was co-financed by a Slovenian national subvention fond for biomass DH-systems (Grant within the national DOLB programme, 50 % co-financing rate).

The project is annually saving 300 t of CO2, and represents a positive example in Slovenia. The only problem encountered in the project was due to slow national administration and slow issuing of needed permits from the side of the Slovenian environment agency (especially water related permits for crossing a local creek).
