About the project
A cleaner view of the physical buffer.
StorageCurve was built to answer a practical market question: is physical energy inventory tight or loose for this point in the season? Official sources publish the underlying observations, but turning them into a current-versus-normal curve still takes work.
The site combines weekly US inventory data from the U.S. Energy Information Administration with weekly-sampled European gas storage data from Gas Infrastructure Europe. It keeps the focus deliberately narrow: the latest observation, last year, the prior five-year seasonal benchmark, and a transparent directional classification.
Independent and free
StorageCurve is independently operated. It is free, requires no signup, and carries no advertising at launch. EIA and GIE are data sources; they do not sponsor, endorse, or review this site.
No manufactured certainty
Physical storage is valuable context, but it cannot explain or predict every price move. The site does not publish a target price, track a model portfolio, or present a storage deficit as a guaranteed trade. The complete formula and exclusions are published on the methodology page.
What may come next
Possible later additions include LNG-terminal balances and an electricity view based on stored and dispatchable energy relative to expected demand. Those require separate source and methodology work; they are not silently mixed into the v1 signal.
