The Natural Gas Storage Regions

map of the United State showing the three natural gas storage regions.

The regions used for weekly reporting were formally the East, West and Producing regions. In October 2015, EIA increased the number of regions and changed their names to better align the storage locations with the markets they serve and to provide more information to market observers and participants. The regions now are:

  • the Pacific Region,
  • the Mountain Region,
  • the South Central Region,
  • the Midwest Region, and
  • the East Region.

The Pacific Region includes the following states: California, Oregon, and Washington.
