Minimising counterparty risk is a key component of the German BESS sector, particularly amid ongoing political uncertainty.
Why it matters: Pure merchant storage is becoming unbankable in Germany; if you can't secure a tolling partner or a revenue floor, your project won't get past the financing stage.
The German BESS market is currently suffering from a severe case of political whiplash. With the collapse of the 'Ampel' coalition, the legislative certainty developers were banking on—specifically regarding the Kraftwerksstrategie and the extension of grid fee exemptions under § 118 Abs. 6 EnWG—is suddenly in limbo. If you're a developer pitching 10MW+ projects today, the era of 'vibes-based' merchant revenue projections is officially dead.
The Death of the Arbitrage Cowboy
We are seeing a hard pivot toward tolling agreements. For the uninitiated, this is essentially a storage PPA where an aggregator—think Statkraft, Next Kraftwerke, or EnBW—pays a fixed fee to rent your battery's capacity. They take the market risk; you take the steady check. It’s the only way to get a project past a credit committee at a Tier-1 bank right now. I’ve sat through enough pitch decks to know that an 8% IRR with a tolling agreement is worth infinitely more than a theoretical 14% merchant IRR that no one will underwrite.
The aFRR Cannibalization Problem
Everyone is chasing the same aFRR (Automatic Frequency Restoration Reserve) and arbitrage spreads on the EPEX Spot. But as Germany's large-scale BESS capacity scales toward the 1.5GW+ currently in the 2024/25 pipeline, those margins will compress faster than most installers realize. We saw this in the UK market two years ago: the early movers feasted, and the laggards starved as ancillary service prices cratered. The 'expert counterparty' mentioned in the news isn't just a safety net; they are the people with the software sophisticated enough to find the €5/MWh margin when the rest of the market is flat.
