BNA Opens 4.5 GW Capacity Tender With September Deadline as Germany Locks In Firm Power Backstop
Germany's first long-term capacity procurement round targets gas-fired, hydrogen-ready generation to back a grid where renewables set a record 58% share in the first half of 2026.
Germany's energy regulator BNA on Tuesday (2026-07-21) formally launched a tender for 4.5 GW of long-term power generation capacity, setting an 8 September bidding deadline for what Montel News described as a long-awaited step in the country's effort to secure firm supply as intermittent renewables dominate more of the grid.7
The 4.5 GW round is an initial tranche of a broader 11 GW programme. German parliament approved the underlying capacity market law by voice vote on Thursday (2026-07-09), and the measure must still clear the upper house before the full framework is legally settled. BNA has moved to launch this first tender while that process runs.6
The political calendar was tight from the start. The German cabinet approved the underlying 11 GW gas-fired capacity legislation on Wednesday (2026-05-20), but parliament did not pass it until nearly seven weeks later. That gap signals the political friction involved in committing public funds to new thermal generation even as official policy pushes toward 80% renewables by 2030.1,6
Legal risk has shadowed the programme since the draft law circulated. Market experts warned during the week of 2026-05-18 that companies whose technologies were excluded or disadvantaged by the tender design could mount legal challenges, Montel reported. BNA's launch of the tender before the upper house vote resolves that uncertainty rather than eliminates it.2
The economics of the plants being targeted hinge partly on European gas prices. ICE Endex TTF front-month traded at €61.90/MWh on Thursday (2026-07-24), setting the fuel-cost floor for any combined-cycle plant that bids. Capacity payments are intended to compensate developers for keeping plants available even when not dispatched, but the payment structure and duration determine whether that compensation is bankable against a 20-year project.7
Germany's power prices demonstrate why firm capacity matters. German power traded at €132.45/MWh on Thursday (2026-07-24). Last spring, day-ahead electricity prices surged 29% on Wednesday (2026-05-27) as a European heatwave drove cooling demand while wind output fell, with wind generation expected to drop to 4.4 GW on Thursday (2026-05-28) from an estimated 9.7 GW the day before, according to LSEG data cited by Reuters.3
Renewable penetration makes those swings sharper, not smaller. Renewable energy covered 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 industry associations ZSW and BDEW. Wind generation jumped 27% in the first quarter from a year earlier, per analysis from the International Economic Forum for Renewable Energies. But hydro output fell 7.7% year-on-year in the first half due to lower rainfall, a reminder that not all low-carbon generation is predictable.5
New capacity competing in the tender will enter a congested grid connection queue. Spain-based Fotowatio Renewable Ventures secured grid access for 2.3 GW of planned renewable and battery storage projects across Germany as of June 2026, with one 750 MW battery facility approaching building approval, according to Power Technology. FRV noted that grid access had become a significant constraint for large-scale developers. Gas-fired plants seeking connections will face the same bottleneck.4
Germany installed 8.3 GW of new solar and 2.5 GW of onshore wind in the first half of 2026, according to ZSW and BDEW — solid progress but short of the 10 GW annual wind target needed to hit the 2030 target. The capacity tender is designed to ensure the thermal backstop expands alongside variable generation rather than trailing it.5
The September 8 deadline is six weeks away. Developers must assess project economics, secure preliminary financing commitments, and weigh the legal exposure flagged by experts — all against an upper house vote whose outcome has not been confirmed in available reporting. A thin response to this first 4.5 GW round would raise questions about the appetite for the remaining 6.5 GW still to be tendered under the broader programme.7,2,6
