AGL Resources' Golden Triangle Storage Open Season Begins

HOUSTON, April 30 -- A non-binding open season begins at 10 a.m. CDT today for AGL Resources' (NYSE: ATG) proposed high- deliverability natural gas storage facility in the Spindletop salt dome in Beaumont, Texas. The open season for 12 billion cubic feet (Bcf) of working capacity will extend through 5 p.m. CDT May 18, 2007.

Golden Triangle Storage, a wholly owned subsidiary of AGL Resources, proposes to develop a natural gas storage facility consisting of two natural gas salt-dome storage caverns. The first 6 Bcf cavern is scheduled for full commercial operation in spring 2011, with the second 6 Bcf cavern scheduled to be in operation in 2013.

Located at a highly liquid market point, Golden Triangle Storage will interconnect with six intrastate/interstate pipelines serving diverse markets with counter-seasonal demand. The project is located near natural gas supplies, including East Texas natural gas fields, offshore deep water wells and natural gas imported through area liquefied natural gas (LNG) terminals.

Prospective customers should contact Ed Gottlob at (832) 397-1798 or Laura McGuire Heckman at (832) 397-8503. Additional information, including bid procedures and a bid form, is available at www.goldentrianglestorage- texas.com.
