The project Toolbox for prosumtion in district heating aims to provide district heating companies with tools for designing standardized offers to prosumers and small-scale heat suppliers. The report presents existing standardized offers and the economic potential for two types of prosumers in different district heating systems.

In buildings having both a heat pump and a district heating connection installed, the operation of the two heat sources can be optimized by an energy company to reduce system costs and in many cases reduce emissions from the heating of the buildings.

It is possible to utilize considerable amounts of demand flexibility in district heating grids? With an extended system boundary that includes buildings, district heating grids, and connection to electricity grids, a co-optimization can be performed that creates great economic value for the economy as well as the environment.
