On October 17, 2008, Southern Company filed amendments to its Market-Based Rate Tariff with the Federal Energy Regulatory Commission (FERC) to incorporate a must-offer, bid-based energy auction. The proposal was conditionally accepted by FERC on December 18, 2008. Southern Company agreed to the additional conditions in a compliance filing on January 21, 2009, and FERC accepted this compliance filing on March 25, 2009. The implementation of the Southern Company Energy Auction subsequently took place on April 23, 2009.
The auction includes simultaneous day-ahead energy auctions for firm-LD energy and recallable energy, along with an hour-ahead energy auction for non-firm energy. More
