As part of the imbalance settlement, the power market operator checks that the balance groups are operating in accordance with their market plan and charges them for any deviations found. The costs of deviations are not negligible for the balance groups. Therefore, the question arises whether there are ways to effectively reduce these deviations. The thesis deals with the modelling of battery storage and its integration between the electricity system and the customer. It further describes the impact of battery storage on the deviations and the associated costs. A procedure for analysing the economic viability of an investment in a battery storage is presented, considering the investment costs, annual cash inflows and cash outflows. The economic viability of the investment is assessed for different battery storage configurations in terms of power and capacity using the net present value and internal rate of return methods. In addition, a sensitivity analysis is carried out assuming the values of the impact parameters for the year 2025. Finally, guidance is given on how to select an appropriate storage configuration to meet the challenge at hand.
