Price Responsiveness in District Heating: Single Houses and Residential Buildings—a Cross-Sectional Analysis

Price responsiveness is argued to be one important factor determining the possibility for a natural monopoly such as a district heating company to exercise its monopoly power. Increased price responsiveness, measured, for example, by the own price elasticity, reduces monopoly power, as consumers increasingly reduce demand as a response to a price increase. However, consumers in single houses having individual metering have presumably higher price responsiveness compared to consumers in residential buildings using collective metering. One major question raised in this paper is thus whether single houses show larger price responsiveness compared to residential buildings. Using cross-sectional data for 187 networks in Sweden for the year 2007 indicates that even if single houses have higher price responsiveness, district heating reveals in general a very inelastic behavior.
