HEAT SOURCE DESIGN FOR DISTRICT HEATING NETWORKS
MULTIPLE HEAT SOURCES PROTECT CONSUMERS FROM ENERGY POVERTY
By John Tang Jensen, Senior Policy Advisor, Clean Heat Directorate, BEIS and Morten Jordt Duedahl, Business Development Manager, DBDH
The present European energy crisis with both very high gas and electricity prices shows that district heating network companies having multiple heat sources and storage sys- tems can keep heat prices low. District heating systems able to use various waste- and ambient heat sources and produce renewable electricity can protect consumers from energy poverty. To achieve a resilient heat price, the normal reserve- and peak-load capacity should be technologies complementing the normal base-low technologies. If, for example, the pres- ent base-load technologies are dependent on low fuel- or electricity prices, the comple- menting technologies should be dependent on high electricity prices like CHP plants or own renewable electricity production units like wind turbines or solar PV.
