GIE AGSI+ recorded EU aggregate gas storage at 29.55% (334.35 TWh) on 13 April 2026, up from 28.92% on 9 April , a gain of 0.63 percentage points over four days 1. The European Commission has cut the November 2026 mandatory target from the standing 90% to 80% , which still requires roughly 0.67 TWh of net injection per day sustained through to November.
The four-day window ran at approximately 1.8 TWh per day on aggregate, comfortably above the target pace. That headline hides the distribution. Germany was net-withdrawing on 13 April , dragging on the aggregate; the 1.8 TWh/day pace depends on faster injection across peripheral storage estates.
The operational consequence is that the 80% target holds only if Germany flips to sustained net injection inside the next five to seven gas days. Each day the anchor keeps drawing is a day the periphery must inject faster to cover, and the capacity asymmetries on the periphery mirror Germany's at smaller scale: pipelines fill only as fast as they fill. A continued draw late into April is the structural signal that the aggregate number cannot maintain the pace.
Bruegel's refill estimate sits on top of an assumption that all member states flip to net injection on similar calendars. That assumption is under test. The EU Council's cutoff on the 25th then removes around 1.5 bcm per month of potential Russian supply into the same refill window, which makes the aggregate line on AGSI+ the single clearest public indicator of whether the November target is still in reach.
