Southern Announces PPA with Progress for New Unit
LCG, July 6, 2006--Southern Company announced yesterday that it has executed a long-term purchase power agreement (PPA) with Progress Ventures, the non-regulated subsidiary of Progress Energy. The agreement calls for Southern to provide approximately 621 MW of wholesale electricity to Progress Ventures from 2009 through 2015.
The electricity is to be generated by a new, combined-cycle power unit to be built at Plant Franklin, located in Smiths, Alabama. The existing plant includes two, gas-fired, combined-cycle units. Unit 1 was placed into commercial service in 2002, and Unit 2 began delivering power in 2003. Construction on Unit 3 had been underway but was suspended in August 2004 pending a long-term power purchase agreement. With the new agreement, Unit 3 is now scheduled to commence commercial operations by the fourth quarter of 2008.
Plant Franklin is owned by Southern's unregulated subsidiary, Southern Power, which has cost-based contracts with other Southern affiliates, Alabama Power and Georgia Power, for operations and maintenance services at Southern Power facilities.
