Weekly Gas Storage Report

Yesterday  (November 19, 2015) the Energy Information Administration (EIA) published its first official weekly natural gas storage report in its new five-region format indicating an injection of 15 Bcf over the past week for a total U.S. inventory of exactly 4 Tcf. The new methodology and reporting format is a vast improvement in the granularity and clarity of government natural gas storage inventory data. But it also potentially moves the target for the slew of industry analysts who lose sleep trying to predict it each week. How the changes impact EIA inventory data and the ability of analysts to predict that data will become clearer in the coming weeks and months. But we got more clues this week as the EIA released dual versions of last week’s report on Monday showing significant differences leading up to launch of the new report on Thursday. Today we compare the results of the old versus new methodology.

The biggest fundamental price indicator in the natural gas market -- Energy Information Administration’s (EIA) Weekly Natural Gas Storage Report – is about to get a major makeover. The EIA is planning to split the US gas inventory data into five regions, from three macro regions currently. The idea has been floating out there for a while, but now it looks imminent, with a good chance it is rolled out before the gas winter season comes around in November. When it does happen, the increased granularity will vastly improve the transparency of natural gas storage inventory data on a weekly basis. But there’s another reason it will be a big deal when it happens:  It will break everybody’s storage scrapes and models. Storage modelers and forecasters will have their work cut out for them. In today’s blog, we break down the upcoming changes.
