This report analyzes the consequences of the proposed changes to the revenue framework presented in the report Ei R2017:07. The analysis is made for Mellersta Skånes Kraft, a small electricity grid company located in the countryside of Skåne county. The analysis presents investment proposals for future regulatory periods.

Energimarknadsinspektionen controls electricity grid owners revenues by setting a revenue framework they are obligated to follow. The revenue framework is divided into regulatory periods that extends over four years, before each regulatory period the regulatory framework is reviewed. This can entail burdensome administrative work, especially for small electricity grid companies as they do not always have the time or resources to fully evaluate the consequences of the changes that are about to come.

The analysis is based on Ei's proposal to change their determination of depreciation times, determination of WACC and their age determination of specific parts of the power grid.

In the result, the revenue frame is presented for two investment options as well as for the existing electricity grid in selected areas in the MSK grid. The result shows that the revenue framework will fall considerably between the current and future regulatory period, much due to the companies’ WACC is expected to decrease and the proposal to abolish the 38-year rule.
