Capacity law faces 24 June hearing

Germany's StromVKG capacity-market law goes to a public expert hearing on 24 June, with a Greens motion and Federal Cartel Office concerns in play before the first 4.5 GW auction targeted for 1 September.

Key takeaway

The 24 June hearing decides whether the 1 September capacity auction date holds.

The StromVKG, Germany's electricity capacity-market law, goes to a public expert Anhoerung (hearing) at the Paul-Loebe-Haus on 24 June 1. A capacity market pays plants to be available rather than for the power they sell, the instrument Germany is using to keep dispatchable gas capacity on the system as renewables grow.

The Greens motion 21/6369 demands technology-neutral auction criteria and clarity on how the levy is financed , carrying forward the hydrogen-conversion push the group raised in committee on 17 June. The Federal Cartel Office, Germany's competition authority, has flagged market-concentration concerns in the design. The bill reached this stage after the Bundestag's first reading and committee referral advanced it under accelerated procedure .

The first 4.5 GW long-duration auction is targeted for 1 September, a second 4.5 GW for 8 December, with a ten-hour continuous-output rule that excludes batteries from the opening tranche. That rule is the design choice with the sharpest market consequence: it hands the first auctions to long-duration thermal plant and shuts storage out of the initial capacity payments.

The hearing is where the 1 September date either holds or slips. The timing connects directly to the spark: CCGTs that have just turned profitable to run are the same plants the capacity auctions are meant to underwrite, so any delay leaves their forward economics resting on the spread alone.

Deep Analysis

In plain English

Germany is creating a capacity market: a system to pay gas power stations to stay available as a backup for when wind and solar are not generating enough electricity. The law establishing it, the StromVKG, passed its first parliamentary reading in June 2026. On 24 June, the German parliament held a public hearing on the StromVKG design. The Greens party wants the rules to be technology-neutral, asking that batteries and other clean technologies also be eligible for capacity payments, rather than gas stations alone. Second, Germany's competition watchdog, the Federal Cartel Office, is worried that the programme would mostly pay money to a small number of big energy companies that already own most of the gas power stations. The first auction is planned for 1 September 2026, with a second in December. Whether those dates hold depends on what comes out of the hearing on 24 June.

What could happen next?
  • Risk

    A successful legal challenge to the ten-hour battery exclusion rule, via either a Cartel Office formal proceeding or an EU Commission state-aid opening, would delay the September auction and leave Germany without the capacity mechanism framework through the current heating season.

    Short term · Suggested
  • Consequence

    If the September auction proceeds on schedule and awards contracts to existing CCGT plant, the gas power stations currently generating at +EUR 30 spark spread receive both a market margin and a capacity payment; double compensation that the Cartel Office's concentration concern addresses.

    Medium term · Assessed
  • Precedent

    Germany's battery exclusion replicates the UK T-4 2014 design error; the EU Commission is likely to require technology-neutral admission within two to three years as occurred in the UK.

The France-Germany day-ahead spread flipped from a EUR 17.20 German premium on 1 August to a EUR 4.15 French premium on 3 August, the same day French curtailment peaked. They cannot yet attribute the flip to curtailment alone, since a like-for-like overnight comparison shows French nuclear output rising while wind fell and demand returned on the weekday step.

River-cooling limits took 7.6 GW, 12 per cent of its fleet, offline on 3 August, the highest curtailment since the heatwave began, with an easing forecast to 4.3 GW on 4 August and 3 GW after. It manages the cut as a recurring seasonal constraint, expecting it to lift with river temperature, not repair.
Gasunie

TTF, the Dutch hub it operates, drifted to roughly EUR 55 to 58 per MWh across the window, staying inside its recent range through both the German spark reversal and the French curtailment. It reads a flat hub price as evidence that neither event this window carried enough weight to move the fuel leg on its own.

Record German solar of 18,761 MW on 2 August pushed the clean spark spread to minus 18.48 EUR/MWh, a loss-making day, before it returned to plus 16.20 on 3 August. They now price dispatch against post-solar residual load rather than wind alone, since the sign flipped inside 48 hours on unchanged fuel and carbon costs.

Its implementing-measures register logged transposition notices from only Portugal and Slovakia against Wednesday's Article 94 deadline for Directive (EU) 2024/1788, with 25 states silent. It expects the register to fill only gradually, since filing routinely lags legislating and any infringement track against non-notifying states runs on a slower clock than the deadline itself.

Spain's 9,145 GWh terminal inventory is the largest single stock in the EU LNG network, an option value that can reroute cargoes wherever the winter strip pays best rather than a cavern gas obligation tied to a fixed date. That flexibility matters more as Germany's cavern shortfall pushes more of the winter security question onto import infrastructure.
