Atlanta-based AGL Resources declined to comment Friday on a Bloomberg report that it is interested in acquiring Alabama Gas Corp. from Energen Corp.

Energen reportedly could get more than $1 billion for the company, which is known as Alagasco and is Alabama’s largest gas distributor with more than 400,000 customers.

AGL spokeswoman Annette Martinez said the company would have no comment on “market speculation.”

Bloomberg based its report partly on comments Hank Linginfelter, AGL’s executive vice president of operations, made earlier this month indicating his company wants to make more acquisitions now that it has integrated Nicor Inc.

AGL, which owns Atlanta Gas Light, became the nation's largest natural gas-only distributor when it acquired Nicor in 2011, resulting in a combined company with more 4.5 million utility customers in seven states.

Bloomberg reported Sempra Energy of San Diego, Calif., also was interested in acquiring Alagasco.
