Regulatory aspects of energy storage in Sweden

Abstract

This paper highlights the possibilities and limitations of investing in energy storage for use at distribution level under the existing regulatory framework in Sweden. The paper further gives a brief overview of possible applications and ownership models for energy storage in a distribution grid. It was concluded that it is allowed for a network operator to own an energy-storage installation; there are however restrictions in the use of the installation for trade in electricity. A general observation from the study was that there are uncertainties in the interpretation of the laws and regulations due to the complete absence of experience in the use of grid-size energy storage.

Technical dimensioning of an energy storage for a Swedish distribution company

“…One of those approaches is aimed at minimizing the losses in the grid. The study presented in this paper was part of a project that also covered regulatory aspects [2] and financial considerations [3] of the construction and operation of energy storage in the distribution network.…”

“…Wind-power producers in Sweden typically do not have balance responsibility for individual wind parks [2]. There is therefore no need for capacity firming of individual turbines.…”
