Episode Details

Germany looks like Europe's most attractive battery storage market on paper: deep power price volatility, a fast-growing renewables build-out, and nearly three gigawatts of batteries already live. In reality, developers are navigating uncertain grid connection queues, gruelling commissioning phases, and a tolling market still working out how much risk is fair to price in.Christina Hepp, Director Strategy, and Leandra Boes, Director Asset Management, both at Green Flexibility, join Ed Porter to unpack what building and operating batteries in Germany actually looks like once the PowerPoint slide meets the grid.They cover:- What a Flexible Connection Agreement actually is and why this kind of trade-off is fast becoming the norm in Germany.- Why grid operators and battery companies have historically struggled to "speak the same language", and how a shared framework like REGIOlink helps translate one side's needs into the other's terms.- What actually happens in the final weeks before a large-scale battery switches on for real: the software integration, testing and last-minute troubleshooting that never makes it into a press release.- Why choosing to sell power on the open market versus locking in a steadier, pre-agreed deal is a much bigger and riskier decision than it sounds - and why Green Flexibility is betting on the option most peers shy away from.- Just how enormous Germany's battery storage pipeline has become: enough grid connection requests queued up that regulators have had to start filtering out the projects that aren't actually going to happen.Want the data behind this conversation?
