Case Study

Expansion of biomass use in Slovak district heating

Trenčín in western Slovak Republic, is a 60,000 inhabitants' town with a long history. The local district heating company Služby pre bývanie provides housing management services with a focus on heat supply. The company recognized the value of biomass for heat production and aims to achieve usage of 70 per cent biomass and 30 per cent natural gas to produce heat.

Služby pre bývanie applied to SlovSEFF  to finance the replacement of gas fired boilers with two biomass boilers. The new boilers consume straw and rapeseed and have the capacity of 4 MW each.
The SlovSEFF team performed the project analysis, assessed its technical-economic parameters and profitability.
The €290,000 investment delivers five times more heat than the gas fired boilers – namely 100,000 gigajoule instead of 20,000. The end consumers will have their heat bills lower by about 10-15 per cent. As of now, 5,200 apartments and six non-residential consumers are heated with biomass. In addition, the new boilers provide less CO2 to the atmosphere, leaving Trenčin a nice picturesque town.
Finally, the local agricultural companies benefit from integration into the energy supply scheme and selling their by-products.
The project is a winning solution for the company, which is decreasing production costs, for the local community, whic is receiving cheaper and cleaner services, and for the city, as it is becoming more energy independent.
This way, the EBRD through SlovSEFF supports the sustainable financing and implementation of energy efficiency projects by the private sector. Together, the private, residential and public sectors can make a change in the energy consumption patterns and contribute to the environmental protection.
