Tenaska Announces Non-Binding Open Season for CO2

OMAHA, Nebraska  Tenaska Trailblazer Partners, LLC (TTP), an affiliate of Tenaska, Inc., is conducting a non-binding open season for the sale of carbon dioxide (CO2) that may be produced by the proposed Tenaska Trailblazer Energy Center (TTEC) under development near Sweetwater in northeast Nolan County, Texas.

The proposed TTEC would be a supercritical pulverized coal electric generating plant with post-combustion capture of CO2. The plant will be designed to capture 85 to 90 percent of the CO2 produced by combustion and deliver it via pipeline to Permian Basin oil fields for use in enhanced oil recovery and. ultimately, geologic storage. The estimated commercial operation date is June 1, 2014.

TTP estimates the TTEC will capture up to 300 million standard cubic feet per day (MMSCFD). A bidder can propose to purchase any amount up to and including 300 MMSCFD.

By submitting a non-binding proposal, bidders are expressing interest in contracting for CO2 under the terms set out in the bid response form. Bid response forms will be ranked by economic value as determined by payment, term, delivery point and other factors selected by TTP.

Interested parties should submit a proposal no later than 5 p.m. central time on August 22, 2008 via e-mail to jjames@tnsk.com.

Further information regarding this non-binding open season, including the bid response form and other specifications, is available from Jeff James, director of business development, Tenaska, Inc., (817) 303-3600, jjames@tnsk.com.
