Item 8.01 Other Events

Public Service Company of Oklahoma (“PSO”) today announced plans to enter into a joint venture agreement with Oklahoma Gas and Electric Company (“OG&E”) to build a new 950 megawatt coal-fueled electricity generating unit at the site of OG&E’s existing Sooner plant near Red Rock, in north central Oklahoma. The pulverized coal generating unit is to be called the Red Rock Generating Facility. PSO will own 50 percent of the new unit, OG&E will own approximately 42 percent and the Oklahoma Municipal Power Authority (“OMPA”) will own approximately 8 percent. Although precise cost estimates for the new facility have not been determined, preliminary cost estimates are approximately $1.8 billion. The facility is expected to be operational in 2011.

The joint venture is the result of PSO’s December 2005 Request for Proposals (“RFP”) in which it sought proposals for new baseload generation to be online in 2011. Six proposals were received by the February, 2006 deadline. Those proposals meeting the RFP criteria were evaluated with oversight from a neutral third-party monitor. The project is contingent upon the successful completion of definitive agreements with OG&E and OMPA, as well as regulatory approvals.
