Atlanta Gas Light Files New Rate Plan

October 15, 2004

ATLANTA--(BUSINESS WIRE)--Oct. 15, 2004--Atlanta Gas Light, a wholly owned subsidiary of AGL Resources (NYSE: ATG), has asked the Georgia Public Service Commission (GPSC) to adjust its base rates beginning May 1, 2005 to cover AGL's increased costs of providing a safe and reliable supply of natural gas to its customers.

AGL has not had a base rate increase in more than 10 years and actually decreased base rates in 2001, saving customers more than $30 million over three years.

"Atlanta Gas Light is proud of the efficiencies we've achieved during the last three years in an effort to mitigate rising business costs and maintain lower costs for our customers," said Kevin P. Madden, executive vice president of distribution and pipeline operations. "Through operating efficiencies, we've kept our request to the commission to less than 1.5% of a customer's total bill (approximately $1.39 per month), far below the average inflation rate."

Madden went on to say that at the same time, AGL has increased customer services, provided additional peaking resources for colder weather, and added more than $108 million in capital additions in Georgia. That is in addition to the 1,540 miles of new infrastructure which has replaced aging pipe to meet the needs of our customers.

AGL is requesting a total base rate increase of $24.6 million:

• $15.6 million from increased depreciation expenses
• $5.6 million to cover various other operating expenses such as pipeline integrity costs mandated by federal regulation, changes in the property tax valuation method
• $3.4 million for capital expenses

While energy costs have risen considerably during the last five years, the base rate increase requested by AGL is not related to the cost of natural gas. AGL is a "pipes only" company, responsible for the delivery of natural gas supplied by certified marketers and for the upkeep of its 55,300-mile pipeline system. AGL's base rate is the price customers pay to have natural gas delivered to their homes.

"A prime example of how AGL is implementing creative solutions for our customers is a peaking solution to provide natural gas on the coldest days of the year, which will save our customers $8.5 million a year over the next 20 years," AGL President Isaac Blythers stated.

Blythers pointed out that AGL, which received the 2003 Platts Global Energy Awards Gas Company of the Year, has been cited by industry peers for efficiencies and best practices. "In this era of higher commodity prices, we are doing everything we can to control our delivery prices," he added, "but we have to be good stewards. It is imperative that our delivery system remain reliable."
