Grid fees, connection charges, and flexible connection agreements (FCAs) increasingly make or break the business models of utility-scale batteries \u2014 one of the most dynamic and most contested fields in the power sector. Connection points, regulation, and system impact are all fiercely debated.<\/p>\n

We advise project developers, investors, grid operators, and policymakers on the grid impact, regulation, and market design of BESS \u2014 through studies, expert reports, and courses. With our BESS optimization model, we quantify revenues under a wide range of market scenarios and assess the impact of connection restrictions.<\/p>\n

Anselm Eicke is our BESS lead.<\/p>\n

Grid impact of BESS (investor).<\/strong> Very large battery storage projects connect directly to the transmission grid, where their impact on congestion and system operation shapes connection terms. For a storage investor, we simulate the grid impact of a very large stand-alone, TSO-connected BESS project. 2026.<\/p>\n

Subsidies for co-located BESS (MECO).<\/strong> Luxembourg\u2019s economy ministry MECO is considering support for utility-scale batteries sharing a grid connection with PV plants. Using our BESS optimization model, we quantified BESS revenues under a wide range of parameters and scenarios and assessed subsidy options, delivering a spreadsheet and an interactive dashboard for the ministry. 2026.<\/p>\n

BESS grid fees & FCAs (project developer).<\/strong> German grid operators restrict the dispatch of batteries through flexible connection agreements. For a battery project developer, we analyzed the project-specific economic impact of balancing limits, schedule freezes, ramp rate limits, and grid fees. 2026.<\/p>\n

BESS grid fees & FCAs (project developer).<\/strong> Grid operators in Germany increasingly use flexible connection agreements to manage the grid impact of battery storage. For another battery developer, we assessed the project-specific financial effects of grid fees and connection restrictions. 2026.<\/p>\n

Grid impact of BESS (battery developer).<\/strong> Battery developers often struggle in grid connection talks, facing uncertainty over the interventions and restrictions flexible connection agreements may impose on revenues. To support a battery developer in a more constructive dialogue with system operators, we assess the expected grid impact of its BESS on the 110 kV network in Brandenburg. 2026.<\/p>\n

Grid-friendly storage (multi client).<\/strong> Germany plans dynamic grid tariffs for battery storage by the early 2030s. For Enspired, E.ON, EWE, and Green Flexibility, Neon, as a subcontractor to UnternehmerTUM, develops the methodology, translating local congestion into time- and location-specific price signals and testing calculation approaches and aggregation levels on real data. Ongoing.<\/p>\n

Regulation of large-scale batteries (ECO STOR).<\/strong> Battery optimization is becoming increasingly constrained by flexible connection agreements and grid fees. For battery developer ECO STOR, we are developing a coherent set of incentives, rules, and restrictions for batteries that minimizes adverse grid impacts while preserving their value for balancing and wholesale markets. 2026.

Grid impact of batteries (multi client).<\/strong> The expansion of utility-scale batteries in Germany faces strong opposition, driven by concerns about their impact on the grid. For a consortium of five battery developers, with Consentec, we outlined the welfare benefits that batteries provide to the power system and proposed guidelines for instruments that improve their grid impact. 2025.

Grid fees for BESS (ECO STOR).<\/strong> Concerns about grid congestion are the main reason grid operators are hesitant to connect utility-scale batteries. With battery developer ECO STOR, we quantified the congestion impact of two sites in the German grid. The result: dynamic grid fees reduce congestion without undermining the batteries\u2019 business case. 2025. Report<\/a>.<\/p>\n
