The base bid has been increased to $990.5 million in a plan amendment filed June 22. The previous bid of $940.5 million was submitted on April 16, 1999. The plan calls for an affiliate of SWEPCO to acquire Cajun's non-nuclear assets and provide power to cooperatives through new, consensual, long-term power supply agreements. The new bid exceeds the rival Louisiana Generating bid by $30.5 million. The increase in purchase price is funded partially by a rate adjustment agreed to by the eight distribution cooperatives that support the joint plan. Rates under the amended plan remain below the level found to be "not presumptively unreasonable" by the Louisiana Public Service Commission. The revised rates remain below those proposed by rival Louisiana Generating. The competing reorganization plans are subject to confirmation by Bankruptcy Court and regulatory approvals. Confirmation hearings are under way, scheduled through June 25, in U.S. Bankruptcy Court in Opelousas, La.
