What is it about?
Heat pumps can provide negative power balance on the reserve capacity market at times of excess power production from wind and/or solar power. The produced heat can be stored at low cost and aid in reducing the utility owners production costs. By consuming cheap surplus power the utility may reduce their production cost, reduce their emissions from burning solid fuels, and at the same time strengthen the power grid with negative power balance, i.e., consumption of electricity.

Why is it important?
Large share of variable renewable electricity generation require contingency in the power system. Heat pumps can consume surplus power from wind and solar power for heat production. Heat can be stored at significantly lower cost than electricity. The stored heat can be used to replace expensive peak load production units, typically fossil fuelled boilers. Since district heating are energy systems dimensioned according to local resources and demands it is important to investigate the potential economic value in offering heat pump capacity on the reserve capacity market.
