​
Scope

Release 1 launches with ~125 curated critical storage facilities, not a global census. Curation bias: facilities that move markets, not every tank farm on earth.
  • Underground gas storage (UGS): top European sites (Rehden, Bergermeer, Haidach, Chiren, etc.), US salt caverns.
  • Strategic Petroleum Reserve caverns: US SPR (Bryan Mound, Big Hill, West Hackberry, Bayou Choctaw), plus major non-US stockholding facilities where published.
  • LNG import & export terminals: Sabine Pass, Corpus Christi, Ras Laffan, Yamal LNG, Asian regas hubs.
  • Crude oil tank farms: major trading hubs (Cushing OK, Rotterdam, Singapore, Fujairah) where operator data is public.

​
Data sources

  • Global Energy Monitor — Storage Tracker (CC-BY 4.0) for facility identity, geometry, capacity.
  • GIE AGSI+ & ALSI for EU gas / LNG fill % at facility granularity (where published).
  • EIA Form EIA-191 for US UGS.
  • EIA SPR weekly stock report for US SPR-level inventory.
  • Operator dashboards where the facility publishes real-time or near-real-time fill %.

​
Fill % — published, not synthesized

If an operator publishes fill %, we show it. If they don’t, we show not disclosed. We never synthesize, interpolate, or country-share a missing fill. When fill data is unavailable at the facility level, the panel falls back to country-level aggregate (e.g. “DE gas storage: 62% overall; Rehden facility fill not disclosed”) — both numbers labeled with their source.

​
Known limits

  • Not every facility publishes fill %. We indicate “not disclosed” explicitly.
  • Capacity figures are typically nameplate, not current maximum working capacity. Working capacity tends to be 75–85% of nameplate for gas UGS.
  • No forecast of storage-days-to-empty here; that computation lands on the country energy drill-down once the disruption log ships in Week 3.

Attribution

Storage-facility registry data derived from Global Energy Monitor (CC-BY 4.0), GIE AGSI+/ALSI (registered API usage), and US EIA open data.

​
Corrections

See /corrections for the planned revision-log shape and submission policy. If a facility you operate is misrepresented, we treat corrections directly from the operator as top-tier evidence — open a GitHub issue at the public repository. Automated override-trigger entries ship with the post-launch classifier; corrections are handled manually today.
