Germany pushed 1,207.5 GWh/day into storage on 27 June with zero withdrawal, the hardest net injection its anchor estate has run all season1. The next gas day held at 1,136.6 GWh/day. National fill climbed from 39.9% on 25 June to 41.21% on 28 June, a 1.3-point gain in three days with no state mandate behind it2.
Germany holds the largest gas storage estate in the European Union, so when it draws down through a refill season the whole bloc's trajectory sags. Through April and May, with TTF (the Dutch Title Transfer Facility benchmark) at €47 to 52, injection economics never cleared, and Germany kept withdrawing while Dutch, French and Italian state mandates carried the refill.
At €40 to 44, gas finally sits cheap enough to feed the CCGT (combined-cycle gas turbine) power stack and the injection caverns at once. German day-ahead power blew out on 30 June to a level that normally pulls every available molecule into turbines and starves storage. Shippers supplied both this time, because the prompt now sits low enough that power burn and cavern-filling stop bidding against each other for the same gas.
The cheapness driving the flip traces to The Gulf. TTF fell into the low €40s after the Iran risk premium drained out of the prompt on 17 June, the same oscillation that now clouds the autumn supply Europe is banking on. The molecules filling the caverns at today's price are cheap precisely because the market doubts the cargoes due in the autumn will all turn up.
