Abstract [en]

This thesis aims to examine and explain growth rate of distributed energy production in Sweden from a sociotechnical perspective. In Germany, growth rate of such systems has been very high for a long period of time where Sweden has seen lower growth rates. The two countries have access to same technology through free trade agreements so differences must be explained with sociotechnical factors. Previous studies has shown that profitability is the most important incentive for an end user’s decision to invest in own energy production, hence the growth rate of such technology in a country, where this report focus on finding, assessing and ranking sociotechnical factors that affects profitability. Technologies examined are small scale solar and wind power plants according to the definition of a microproducer. Customers were all assumed to have the investment as an optional supply of own energy and not their primary, hence no risk for black outs or freezing. Cultural, economic and political differences between Sweden and Germany greatly impact profitability of distributed energy production which could explain the difference in growth rate. Where good profitability can be achieved in Germany, no realistic scenario in Sweden showed profitability. Most notably, the German government provides long term beneficial feed-in tariffs, low interest loans and investment support in addition to a pronounced plan to change the counties energy system. For someone that decides to invest in distributed energy production despite poor profitability, the areas of investment cost per KWp, plant utilization and current price of electricity are the three most important to consider to increase profitability.
