Storage Regions

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.

Analyst estimates for this week’s Energy Information Administration (EIA) Weekly Natural Gas Storage Report before its release were rallying around an expectation of a 95-Bcf injection, according to the Wall Street Journal’s survey of storage analysts. The actual number reported by EIA yesterday (July 16, 2015) was a 99-Bcf injection, more or less in line with analyst expectations. But predictions may get a bit harder later this year. The EIA is preparing to redraw its US natural gas storage map and begin reporting inventory data in new regions later this year (2015). In August, prior to the launch of the revamped report, it will release a file with historical data for each of the new regions. The historical data will for the first time allow modelers to run their regressions and gather statistical information by which to rebuild their storage models designed to foretell the weekly EIA storage number. In the meantime, we did our own unscientific analysis of the regional breakdown and how it will change transparency in gas storage activity. Today, we examine storage capacities in the old versus new regions and potential impact on analyst visibility.
