Dynamic Electricity Pricing for Battery Grid Feed-in Subsidies

This document, commissioned by ECO STOR GmbH, explores the integration of large batteries into the grid fee system through dynamic electricity prices. It highlights the multiple values of large batteries in the power system, including balancing power for wind and solar, and ensuring energy supply security. The paper addresses the controversial impact of batteries on grid bottlenecks and redispatch costs, noting that current battery usage can reduce costs but lacks systematic incentives. The authors propose a dynamic electricity price mechanism adjusted daily by grid operators to reflect supply and demand tensions, which can significantly reduce redispatch costs more effectively than fixed fees. The document also discusses the investment boom in large battery projects driven by falling costs and market price differences, despite the absence of subsidies. It aims to provide a scientific basis for policy-making and promote grid-friendly behavior through optimized grid fee structures, ultimately enhancing the national economic value of battery storage.

Dynamic Battery Grid Fee Proposal for Grid Compatibility

This consultation paper, commissioned by ECO STOR GmbH and authored by Lion Hirth and Clemens Lohr, proposes a special dynamic energy charge for large-scale batteries to enhance grid compatibility. Large-scale batteries already perform critical roles in the electricity system, such as providing balancing power and compensating for forecast errors of renewables, but their grid impact is currently coincidental due to the lack of congestion pricing in the German market design. The paper evaluates various grid fee structures and finds that a dynamic energy charge, set daily by grid operators based on expected congestion, can reduce redispatch costs five times more effectively than static fees. This charge incentivizes batteries to adjust operations to grid conditions, increasing their macroeconomic value. The proposal aims to structure the debate on battery grid fees, which is a key topic in the BNetzA grid fee reform. The paper also notes that batteries, unlike gas plants or renewables, receive no subsidies, making investor interest encouraging despite grid connection challenges.
