Case Study (111 Kb) 

Summary

The project includes modernization of two independent district heating systems with a current total installed capacity of 50 MW, servicing in total 15,000 inhabitants of the town of Jindrichuv Hradec in Southern Bohemia. It includes interconnection of the two DH systems, a complete switch from steam to hot water district heating and thus the increase in energy efficiency of heat distribution, and fuel switch from oil to natural gas and biomass (wood waste), and installation of a small co-generation unit and solar heating in a swimming pool.

Results

A major benefit of this project is in the first place a significant improvement in the air quality in the town of Jindrichuv Hradec and the neighbouring region at the Czech-Austrian border. The emissions of sulphur dioxide, nitrogen oxides, and fly ash will decrease by as much as ca 86%, and carbon dioxide emissions will decrease by more than 20%.

A 70% investment subsidy will allow a decrease in the current level of heat price from €13/GJ to €11.6/GJ, the internal rate of return of the remaining 30% investment is 12%.
