Under the request, Duke Energy Ohio is seeking either purchased power agreements of 30 years or asset ownership proposals for generation resources that will be dedicated to serve its Ohio customers under the new Ohio energy law signed by Gov. Ted Strickland on May 1, 2008.

"Our generation resource plan indicates a need for peaking and intermediate electric supplies to meet our customers' energy demands," said Sandra Meyer, president of Duke Energy Ohio. "While we recently issued a separate request for proposals for renewable energy supplies, the new request recognizes the need for obtaining long-term traditional supply that is currently provided under short-term arrangements."

Duke Energy Ohio will give preference to assets located in the Midwest Independent System Operator (MISO) footprint or which are currently deliverable to MISO. The request for proposals also specifies that bids must be of a minimum block of 50 megawatts.

The company has retained Burns & McDonnell to act as an independent third party during the evaluation of the bids. All questions from bidders on the request for proposals should be sent to [email protected] A web site, DukeEnergyOhioRFP.com, has also been established. Answers to questions will be posted to the web site so they will be available to all potential bidders.

Bids must be received by Burns & McDonnell by 4 p.m. CST, Aug. 29, 2008. Prospective bidders must provide a notice of intent to bid by Aug. 15, 2008. Duke Energy Ohio expects to complete negotiations in the first quarter of 2009.
