A battery energy storage system (BESS), battery storage power station, battery energy grid storage (BEGS) or battery grid storage is a type of technology that uses a group of in the grid to store . Battery storage is the fastest responding on , and it is used to stabilise those grids, as battery storage can transition fr.
Potential funding options for the project include debt financing (e.g., international financial organisations, commercial banks), equity financing (e.g., capital investment), and project finance.
In 2025, the electricity storage capacity charge will be €87.5/MW per month, i.e. half the capacity fee for a power plant. In addition, Fingrid is planning a reform of the connection fee, which aims to increase the contribution of new entrants to the network reinforcement needs they create.

As BESS capital costs continue to decline, ROI remains attractive. Estimates suggest a 1 MW/2MWh BESS can generate ~€100,000/MW/year in revenue, with higher earnings possible through intraday and balancing market participation. These levels position Sweden competitively against major European markets.
