Leag and rivals set to oversubscribe Germany's first 4.5 GW capacity auction
Montel's industry poll suggests the 8 September tender will draw more bids than available capacity, with legal and regulatory risks still clouding the broader 11 GW scheme.
Germany's first 4.5 GW power capacity tender, due to close on 8 September, is likely to attract more bids than it can clear in a single round, a Montel poll of power companies conducted during the week of 20 July (2026-07-20) found.5
Among those confirming participation, eastern Germany's Leag said it plans to bid for new generation at its existing Lippendorf and Schwarze Pumpe sites, which together already house more than 3 GW of lignite-fired capacity.5 The entry of a lignite incumbent alongside presumably gas-fired and storage applicants suggests Berlin has cast a wide technology net in the first round — a design choice that can attract volume but invites disputes over how different asset classes are treated in clearing.
The tender is designed to address a capacity gap that Germany's accelerating renewable build is making more urgent. Renewable energy supplied a record 58% of Germany's electricity consumption in the first half of 2026, up from 55.8% in the same period of 2025, according to estimates by industry bodies ZSW and BDEW.3 Germany installed 8.3 GW of new solar capacity and 2.5 GW of onshore wind in those six months alone, with wind output jumping 27% year-on-year in the first quarter per IWR analysis.3 Germany's own target calls for 10 GW of annual wind additions to reach 80% renewable generation by 2030, a rate that H1 2026 installation data shows is not yet being met. Faster intermittent penetration in the meantime raises the need for dispatchable capacity that can cover low-wind, low-solar periods.
German Power front-month settled at €132.64/MWh as of Thursday's close (2026-07-24), with the day-ahead at €125.82/MWh for the same session. The Q+1 contract at €146.72/MWh priced above the front-month, while Cal+1 at €111.40/MWh traded below it, with the annual forward contract sitting well below current spot levels.
The September auction is the first tranche of a broader 11 GW program. The European Commission told Montel it aims to approve Germany's planned tenders for gas-fired capacity "as soon as possible," but only once Berlin formalizes a long-term capacity scheme.4 That conditionality leaves subsequent tranches in a regulatory holding position while the first round proceeds on its own timeline.
Legal risk runs alongside. Market experts told Montel during the week of 18 May (2026-05-18) that the draft power plant law underpinning the 11 GW plan could face legal challenges from companies believing their technologies were disadvantaged by the tender design.2 Those challenges have not materialized publicly, but they remain a live exposure for generators bidding into the program while the broader legislative framework stays legally untested.
The European Commission separately approved in May 2026 a EUR 3.8bn subsidy scheme to cut electricity costs for German energy-intensive industrial users over three years.1 That plan addresses demand-side affordability, not generation adequacy, leaving the capacity shortfall for the auctions to resolve.
ICE Endex TTF front-month ended Thursday (2026-07-24) at €63.76/MWh, up roughly 3% on the session. Gas-fired developers assessing the September tender will be modelling dispatch economics against fuel costs at that level across a multi-year capacity payment outlook, making current TTF pricing a direct input into bids due by 8 September.
Confirmed oversubscription would show that Berlin's capacity market design is generating genuine developer engagement. But a fixed-volume round that rejects a large share of bids shifts the focus to what comes next: whether rejected proposals carry into later tranches, require restructuring, or fall away entirely. The clearing price and rejected-bid volume published after 8 September will offer the first hard read on how much of the 11 GW target is achievable within the program's current design.5,4
