Operations Initiated at Southern Company's Carbon Capture Project

LCG, June 15, 2011--Southern Company announced Monday that operations of its carbon capture and storage (CCS) facility have commenced at Plant Barry, a coal-fired power plant located near Mobile, Alabama.

The new CCS facility will capture from the flue gas stream of the power plant approximately 150,000 tons of carbon dioxide (CO2) per year, which is about the quantity of emissions associated with 25 MW of generation. The carbon capture system employed is provided by Mitsubishi Heavy Industries Ltd. technology KM-CDRâ„¢, which uses an advanced amine solvent that reacts with the CO2 from the flue gas. Ultimately, the captured CO2 will be compressed and injected underground, where it will be sequestered in a deep saline geologic formation.

Southern Company Chairman, President and CEO Thomas A. Fanning stated, "This is a significant milestone in our continuing efforts to research, develop and implement 21st century coal technologies. Because coal is a low-cost and abundant natural resource, it is important for Southern Company and the industry to preserve coal as a fuel source."

The captured CO2 at Plant Barry will be delivered to the Southeast Regional Carbon Sequestration Partnership (SECARB) managed by the Southern States Energy Board for transport approximately 11 miles via high-pressure pipeline to a site within the Citronelle Oil Field that is operated by Denbury Resources. At the site, the CO2 will be injected about 9,500 feet underground for permanent storage in a formation that was previously tested and evaluated by SECARB. The CO2 will not be used to support enhanced oil recovery.

Plant Barry is owned and operated by Alabama Power, and the CCS facility is owned and operated by Southern Company Services (SCS), both of which are subsidiaries of Southern Company.
