Distributed heat power in district heating nets

Purpose and goal

Purpose: facts allowing to evaluate the technical and commercial potential of an innovative concept regarding distributed heat power have been compiled. Goal: the market potential of a system where the district heating net is enabled to provide two useful products, heat and electricity, has been assessed. Produced electricity would primarily serve as reserve and balancing power.

Expected results and effects

Larger buildings and facilities with a need for reserve electricity include shopping malls, universities, hospitals, airports, data centers and the like. Electricity can be provided by heat-to-power technology, and thereby total costs for heat plus electricity may be lower, diesel för reserve power can be replaced, district heating (DH) can be used more efficiently (summer), and the DH net in its entirety can contribute to increased security of pow er supply. The result report includes system description, economic analys as well as a business plan.

Planned approach and implementation

Climeon acted as project leader and cooperated with SP and SWECO. The system description was provided by Climeon. Characterisation of technical demands and specifications (back up electricity supply) as well as the final report were provided by SP and SWECO. The business plan was developed by all three partners.
