Utility-scale Storage: New Challenges and New Strategies

Tuesday, June 23, 2026, 11:30 am - 01:00 pm

ICM München Room 13 A

As the energy storage market has evolved, one of the biggest barriers to battery storage deployment is grid connection. In Germany, one of Europe's most attractive markets, several gigawatts of storage remain stuck in connection queues, which questions project business cases as long-term revenues are unknown and projects cannot go online soon to benefit from existing prices and market conditions. Limited grid capacity means developers must act proactively and think creatively. Possible solutions include closer collaboration with DSOs to enable system-friendly integration, co-locating batteries with PV to use existing infrastructure, or cable pooling to optimize grid usage. Therefore, beyond trading and arbitrage, strategies like infrastructure sharing, partnerships with optimizers, and renting out batteries through tolling instead of developing projects are gaining ground. This session will examine how to navigate grid constraints and unlock the full value of storage in today's evolving energy system.
