Germany’s utility-scale battery deployment is hitting an inflection point.
After years of projects piling up in development pipelines, utility-scale storage is arriving at gigawatt scale – just as Germany’s huge solar fleet drives electricity prices towards zero, or below, during sunny hours.
For batteries that can shift that power into higher-priced periods, the opportunity is enormous.
Host Jonathan Gifford speaks with Thaddäus Kreisig, Principal at Aurora Energy Research, about Germany’s forming battery boom – and how developers are building revenue stacks to make projects viable.
The shift is striking: more than two-thirds of solar developers recently surveyed by Aurora said every project they plan to deploy will be co-located with a battery system. Falling battery-system equipment costs are strengthening the business case, while arbitrage, ancillary services, EEG revenues, and new financing models are opening up ways in which battery energy storage systems can pay off.
But grid constraints remain a major hurdle. Flexible connection agreements can restrict when batteries charge and discharge – limiting revenues, even as energy storage could help resolve the German energy market’s pricing peaks and troughs.
In short, Germany’s massive solar fleet has created both the need and the opportunity for batteries. And energy storage is rapidly shifting from optional extra to essential infrastructure – but the route-to-market for projects certainly promises to be an interesting ride.

Germany helped pioneer the political frameworks that made solar a global success. But with daytime electricity prices falling, solar companies under pressure, and significant policy reforms taking shape, could the impressive solar and battery installation rates of recent years slow dramatically?
Europe has some of the world’s best solar researchers and strongest local markets. So why is so much of the PV manufacturing happening somewhere else?
The Dunkelflaute has become one of the most persistent arguments against a fully renewable energy system. When the sun isn’t shining and the wind isn’t blowing, where is our energy supposed to come from?
Despite claims that the energy transition is losing momentum, solar and battery deployment continues to run ahead of forecasts – profoundly impacting electricity markets and the wider global energy system.
An increasing number of solar marketplaces have entered a new phase – one where achieving strong, ongoing installation rates depends heavily on system flexibility. Recorded live at The smarter E Europe 2026 in Munich, this episode of pod brings together two conversations that examine how solar marketplaces are changing in the face of this new reality, which includes falling capture prices and the rapid rise of battery energy storage.
