HOT|COOL NO. 2/2017 - "The Winter Package"


Litomerice, Czech Republic Currently, coal-based district heating in the municipality covers 37% of the overall heat demand, other sources being individual natural gas boilers (62%), biomass boilers and solar thermal collectors. Maintaining the level of individual natural gas boilers would not lead to the reductions in CO2 emissions which the municipality would like to achieve. For district heating, the conversion to a geothermal CHP is a feasible solution, because the municipality has large geothermal potential and such a scenario would allow fuel savings and would generate revenue by electricity production. It would also result in a substantial CO2 emission reduction. However, network reinvestments will also be necessary. Other analysed scenarios include large heat pumps and thermal storage, which in the future also appear to be more feasible than the current coal- based heat supply.

Success factors for district heating and cooling In the course of the project, the main success factors of district heating and cooling were classified into: planning, regulative and economic factors. Strategic local and regional heating and cooling planning requires long-term environmental targets at the local and national level, information campaigns and collaboration, good availability of geographical data, as well as competences and time to use planning tools at a local level. Regulation could provide zoning that would prevent double infrastructure (e.g. natural gas and district heating networks), ownership structures ensuring equal access to grids and possibly mandatory energy efficiency improvements. These could include requirements for heat savings in buildings, improvement of district heating and cooling grid and district heating and cooling expansion goals. Economic success factors include: access to inexpensive long-term financing or subsidies, risk-taking by industries, increased district heating connection rate in parallel with implemented heat savings in district heating areas to avoid district heating price increase, non-profit district heating and cooling, aligned taxes, tariffs and subsidies for: CO2, fuels, electricity for heat pumps and use of excess heat. Further work Most local case study analyses have revealed a techno- economic potential for district heating implementation and expansion but specific policy recommendations to improve the business case will be available in summer 2017.
