Episode Details

Germany’s battery boom is charging ahead - without subsidies. So how is it working?
While many markets rely on government support to kickstart energy storage, Germany is doing things differently. With more than 500 GW of battery connection requests in the pipeline, it’s quickly becoming one of Europe’s most competitive and dynamic battery markets.
From stacking wholesale and ancillary revenues to striking new kinds of long-term contracts, we explore how Germany’s storage sector is evolving in real time and how that’s changing the game for developers, corporates, and financiers alike.
In this episode of Transmission, Martin Daronnat, Head of Flexibility and Structured Origination in Germany at Engie, joins Quentin to explore the market mechanisms, commercial strategies, and contract structures that are enabling battery storage to scale, without public funding.
Highlights include:

• How batteries in Germany stack revenue across energy, capacity, and grid services.
• Why fixed-price flexibility agreements are emerging as a key financial innovation for managing merchant risk.
• The role of large industrial players, and why developers and buyers are both leaning in.
• What other countries can learn from Germany’s approach, especially when it comes to risk appetite and regulatory design.
