In this episode, Tom Smout speaks to Philipp Man co-founder and CEO of terralayr, about the realities shaping Germany’s battery storage market. From grid bottlenecks and evolving grid fee structures to merchant risk and hybrid revenue strategies, Philipp shares his perspective on why flexibility will be central to Germany’s industrial and energy future, and how terralayr is approaching the commercialisation of grid-scale battery storage assets.

We discuss:

• Why grid access and connection constraints remain the biggest bottleneck for battery deployment in Germany
• How evolving grid fee structures and locational pricing signals could reshape project economics and investment strategies
• Why hybrid commercial models that combine contracted revenues with merchant optimisation may become increasingly important for battery developers

What’s one thing you would like listeners to take away from this?

• Battery storage is no longer a niche technology. Flexibility is becoming essential to the future of power systems, and the ability to navigate grid constraints, market volatility and evolving revenue models will define the next phase of growth in Germany’s energy transition.
