Germany's clean spark spread turned negative on Thursday 21 May with TTF at EUR 47/MWh and EUA at EUR 75/t putting CCGT marginal cost near EUR 129/MWh against day-ahead clearing of EUR 106.35; commercial gas-injection economics broke at the EU's largest storage estate, with EU aggregate fill at 37.0% on 22 May at 0.17 pp/day pace against 0.53 pp/day required for 80% by 1 November.
The injection deficit is now a market-design problem inside Germany's own electricity stack, not a procurement problem; a sub-80% landing on 1 November is the operative consensus.
