The purpose of this project was to find a way to measure the market for microgrids in district heating in Germany, to figure out what the benefits of using microgrids in district heating are, and to see what might be stopping the expansion of these microgrids. This was done by interviewing five different companies or organizations with different roles or viewpoints, but all were in the business of district heating. The interviews were done online, and the questions were divided into five categories: Background, Benefits, Hindrances, Future, and Others.

The interviews gave the results that there are a lot of benefits to using district heating, but that the benefits will decrease with the size of the system, but there are some additional benefits of being smaller as well. It also showed that there are hindrances with microgrids but that those can be overcome by different means. The hindrances and decreased benefits also laid the foundation for the discussion on how one can measure the market which resulted in five different steps: checking the number of potential customers, the energy density, whether there are any local heat sources, how the project is being financed, and in the end how will the economy of scale look like.
