LNG is natural gas that has been cooled to about minus 260
degrees Fahrenheit for storage as a liquid. LNG is more compact
than its gaseous equivalent with a volumetric difference of
approximately 600 to 1. This difference in volume allows AGL
Resources to store a large quantity of natural gas in a
relatively compact storage space. Most LNG storage facilities in
the United States were constructed solely for use by local
utilities. Storage facilities in utilities' service areas often
hold LNG for an extended period of time to meet peak demand. LNG
accounts for only a small portion of working gas in storage, but
it often represents a significant part of a company's supply
portfolio for peak days. LNG facilities are often constructed
with a higher degree of "deliverability" (the amount of gas the
facility can send out under peak conditions relative to
inventory) than traditional underground storage facilities such
as depleted reservoirs, aquifers and salt caverns. AGL
