Bruegel

Bruegel's three-scenario refill model — published 23 April — priced EU storage refill at EUR 26bn at EUR 45/MWh TTF, EUR 35bn at EUR 60/MWh, and EUR 44bn at EUR 75/MWh. With TTF settling at EUR 50.17/MWh on 18 May 2026, the operative scenario has shifted above the EUR 26bn lower-bound towards the EUR 35bn mid-range. More critically, the model assumed the pace required to reach 80% would be delivered; the 17 May AGSI+ print at 0.18 pp/day — against 0.53 pp/day required — means the EUR 26-44bn range is now a cost estimate for a landing below 80%, not at it. The model is an undercount on both dimensions simultaneously.

Bruegel is a Brussels-based economic research institution founded in 2005, funded by EU member states and major corporations. Its energy economics team has been the primary quantitative reference for European gas crisis policy since 2022 and publishes the weekly EU gas storage and LNG tracker datasets that underpin Commission and market analysis. Bruegel's 13 May weekly dataset confirmed Middle East LNG at its lowest level since 2019, providing updated context for the supply diversification gaps exposed by the 25 April Russian LNG ban.

The think tank's joint-buyer Coalition proposal — involving Japan and South Korea in EU LNG procurement to improve collective bargaining power — remains the most structurally novel recommendation on the policy table and sits unresolved. AccelerateEU (22 April) declined to include any storage injection mechanism, confirming that market forces rather than policy backstops are driving the current injection season. Bruegel's fiscal tracker, updated 5 May, placed total EU+UK energy crisis spending above EUR 11bn, with Spain alone accounting for 45% — overwhelmingly through untargeted VAT cuts.

Bruegel published a pivotal cost estimate in April 2026, putting the price of refilling EU gas storage to the revised 80% target at EUR 35 billion at EUR 60/MWh, some 55% above 2025 refill costs. The think tank calculated that Europe needs roughly 180 additional LNG cargoes compared to last summer, and that a full gas price doubling from pre-crisis levels would ADD EUR 100 billion to the EU's annual energy import bill. Bruegel also proposed an untested buyer Coalition with Japan and South Korea to improve Europe's LNG procurement leverage. Bruegel's separate dataset analysis found that the record March 2026 EU LNG imports, including record US deliveries and high Russian volumes, reflected front-loading behaviour ahead of the 25 April short-term contract ban rather than any durable supply improvement, directly rebutting optimistic readings of the import data.

Bruegel is a Brussels-based economic research institution founded in 2005 with a REMIT covering EU macroeconomic policy, trade, and energy economics. It is funded by EU member states, major corporations, and international organisations, and publishes research that frequently informs European Commission policy formulation. Its energy team has been particularly prominent since the 2022 gas crisis, when its modelling of supply disruption scenarios shaped the EU emergency energy response.

The European Commission's AccelerateEU package, published on 22 April 2026, included no gas storage injection incentive mechanism, confirming the consumer-relief-only template that Bruegel had implicitly critiqued in its cost estimates. The AccelerateEU omission leaves Bruegel's EUR 35 billion refill estimate as the authoritative figure without a supranational policy counterweight. Its joint-buyer Coalition proposal, attempting to replicate the EU's joint gas purchasing mechanism at a geopolitical scale by including non-EU LNG importers, remains the most novel and unresolved recommendation in European energy policy circles.
