Germany conducted its inaugural capacity auction to secure reliable backup power as the nation phases out coal and expands renewable energy sources. The auction awarded all 5.16 gigawatts of derated capacity—a measure adjusted to reflect each project’s expected contribution to grid stability—exclusively to gas-fired generation projects.
The results demonstrate how existing power plant sites provide substantial competitive advantages in the current market structure. Major generators LEAG and RWE secured more than 99% of the awarded capacity, with LEAG’s success particularly concentrated at its established lignite sites. Industry analysts note that access to existing grid connections and infrastructure helps developers reduce investment costs and accelerate project timelines, giving established operators a significant edge over new entrants.
The auction’s technical specifications shaped which technologies could compete effectively. The first round required projects to deliver at least 80% of their installed capacity for 10 consecutive hours, a duration requirement that favored gas generation and created economic challenges for battery storage systems seeking to participate. This outcome reflects the specific type of backup supply Germany targeted, particularly for managing Dunkelflaute periods—extended intervals of low wind and solar output.
Competition among bidders resulted in lower prices, though costs remain substantial. Nearly 12 gigawatts of bids competed for the 4.5 gigawatt procurement target, bringing the volume-weighted average award price to approximately €155,000 per derated megawatt annually—36% below the ceiling but exceeding recent European capacity auction benchmarks. The awarded projects include hydrogen-readiness requirements, which adds to their complexity and limits direct cost comparisons with other markets.
Future auction outcomes may shift depending on how Germany structures subsequent rounds. Adjusting duration requirements and contract terms could create more favorable conditions for battery storage and alternative flexibility sources. Winning gas plants position themselves as potential customers for hydrogen suppliers, though the long-term economics of switching from natural gas to hydrogen remain uncertain.
