Studies

We have successfully published more than 40 studies. On the one hand, these are studies for governments, grid operators, and regulators, documenting and justifying regulatory decisions. On the other, they are projects for companies that use them to weigh in on energy policy debates.

With our long-standing project experience, our deep grasp of regulatory detail, and our rigorous commitment to scientific standards, we set ourselves apart from other consulting firms. Effective communication through plain language and concise graphics is an integral part of our work. Our studies are never just a slide deck – they always include a fully written report. We support publications in traditional and social media.

Communication and reach matter to us. Our social media channels have more than 90,000 followers combined. That reaches a large part of the energy policy community in Germany and Europe.

Grid Fees for Batteries

multi client · 2026

Germany plans dynamic grid fees for storage from 2030. For enspired, E.ON, EWE NETZ, and green flexibility, we translated HV/MV substation congestion into locational, time-varying price signals and tested them on real 2025 grid data.

Injection charges for offshore wind

BWO · 2026

Germany’s regulator plans to charge generators for grid costs from 2029, aiming to relieve consumers and incentivize grid-friendly behavior. For the offshore wind association BWO, we find neither is met: as the state largely sets sites, connections, and capacity, the charge cannot steer behavior and raises CfD bids, burdening the federal budget.

Regulation of large-scale batteries

ECO STOR · 2026

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.

Marginal pricing

Eurelectric · 2026

The debate about marginal pricing and the “merit order” has flared up again, with policymakers proposing wholesale interventions echoing the “Iberian Mechanism.” For the industry association Eurelectric, we produced a short study benchmarking prices against other markets, explaining marginal pricing, and debunking key merit-order misconceptions.

Regional wholesale prices

Regional wholesale prices

Enercity · 2026

Few energy policy questions are debated so fiercely as the split of the German bidding zone: the wholesale market is blind to grid congestion, leading to inefficient dispatch, costly redispatch, and distorted cross-border trade. For the utility Enercity, we delivered a study on the pros and cons of uniform, zonal, and nodal pricing.

Grid impact of batteries

multi client · 2026

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.

Price spikes

Price spikes

50Hertz · 2025

Episodes of extremely high power prices have raised concerns about capacity withholding. For TSO 50Hertz, we evaluated the economic causes of extreme prices, including whether plant operators withheld capacity to artificially inflate them, and developed practical recommendations to prevent future price spikes and mitigate their effects on consumers.
