Germany Revamps Its Energy Laws, but Risks Locking Itself Into Decades of Costly Gas Import Dependence

Why It Matters

Treating batteries as a first‑order resource could lock Germany into cheaper, cleaner flexibility and prevent decades of costly gas dependence, shaping Europe’s broader energy security agenda.

Key Takeaways

• Germany's draft law may favor gas plants over battery storage
• Battery capacity could cut renewable curtailment by one‑third
• Avoided curtailment could save about $870 million annually
• Over 2 million German homes already have battery systems
• Europe needs 60 min storage; Germany only has 15 min

Pulse Analysis

Germany’s upcoming Electricity Supply Security and Capacity Act is poised to reshape the nation’s power‑market architecture at a critical juncture. By introducing capacity auctions to cover "Dunkelflaute" periods—times of low wind and solar output—the legislation could inadvertently cement a reliance on gas‑fired peakers if batteries are not granted equal status. This policy choice matters not only for Germany’s climate targets but also for the broader EU goal of reducing fossil‑fuel imports amid geopolitical volatility.

Battery storage, however, is rapidly becoming a cost‑competitive alternative. Germany already accounts for a quarter of the EU’s large‑scale battery capacity, with more than 2.5 GW expected online by the end of 2025 and a pipeline surpassing 10 GW. Ember’s analysis shows that fully deployed batteries could have prevented roughly one‑third of the 8 TWh of renewable curtailment recorded last year, translating into about $870 million in avoided gas purchases and redispatch expenses—far exceeding the $163 million lifetime investment cost. The residential market mirrors this trend, with over two million home‑battery systems installed and one in six households already using them.

The decisive factor now is regulatory clarity. Ember urges policymakers to treat batteries as a first‑order flexibility solution, alongside demand‑side resources such as electric‑vehicle charging and heat‑pump load shifting. Aligning the capacity auction framework with the falling cost curve of storage would accelerate the transition to a resilient, low‑carbon grid and safeguard Germany from decades of expensive gas imports. For investors and utilities, the signal is clear: the next wave of profitability lies in clean‑flexibility assets, not in new gas infrastructure.
