| Tenaska Proposes Nation's First New Conventional 
    Coal-fueled Power Plant to Capture Carbon Dioxide   ARLINGTON, Texas, Feb 19, 2008 /PRNewswire
 Tenaska, Inc. is developing a site near Sweetwater, Texas, upon which to 
    construct a technologically advanced coal-fueled electric generating plant 
    able to capture up to 90 percent of the carbon dioxide (CO2) that would 
    otherwise enter the atmosphere. The carbon dioxide would be sold for use in 
    enhancing oil production in the Permian Basin, resulting in geologic 
    storage.
 
 An air permit application, the first formal step in gaining approval to 
    build the plant, was filed today with the Texas Commission on Environmental 
    Quality (TCEQ), according to David Fiorelli, president and CEO of Tenaska's 
    Business Development Group.
 
 The proposed construction site is a 1,919-acre tract east of Sweetwater and 
    north of Interstate 20 in Nolan County. The more than $3-billion project 
    will provide a significant boost to the local economy, providing up to 2,000 
    jobs at peak construction and more than 100 permanent well paying jobs 
    during operation.
 
 The final decision to proceed with the project will be made in 2009 based on 
    a number of factors, including the availability of local, state and federal 
    incentives; final project cost estimates; and projected market prices for 
    electricity and CO2. Current estimates of these factors make the project 
    appear to be economically feasible.
 
 Speaking to a group of Sweetwater business leaders today, Bill Braudt, 
    Tenaska's general manager of business development, said that "the benefits 
    of this proposed plant are many. It will provide a source of badly needed, 
    environmentally sound electric generating capacity. This plant will use 
    abundant and relatively low-cost coal and help keep Texas electricity prices 
    in check."
 
 "It is exciting to see this innovation coming to West Texas," said Texas 
    State Senator Robert Duncan. "Tenaska's approach to energy generation 
    through the capture of 90% of carbon dioxide and reduced water consumption 
    is unique, and we West Texans pride ourselves on seeking new ways to achieve 
    better results. We expect a strong partnership with Tenaska that will 
    revolutionize this industry."
 
 Tenaska is working with Sweetwater area officials to determine the 
    feasibility of the project and to provide accurate and timely information to 
    Sweetwater area residents.
 
 Helen Manroe, manager of business development for Tenaska, meeting with 
    Nolan County leaders, pointed out that the Tenaska Trailblazer Energy 
    Center's captured CO2 "will make a major contribution to the Sweetwater and 
    West Texas economies.
 
 "The carbon dioxide produced and captured by this product will enable Texas 
    to increase oil production and thus reduce the nation's dependence on 
    foreign oil," she added.
 
 "Nolan County is home to more wind turbines than any other place in the 
    United States," said Nolan County Judge Tim Fambrough. "The Tenaska 
    Trailblazer Energy Center builds on this area's reputation as a location for 
    progressive, environmentally responsible electric generation. We are 
    delighted to welcome Tenaska to our community."
 
 If built, the plant will be the first new commercial coal-fueled power 
    plant, other than small research projects, to capture and provide for 
    storage of CO2, considered by many a greenhouse gas that contributes to 
    global climate change. As such, it would be a first-of-its-kind breakthrough 
    in environmentally responsible electricity production that has been sought 
    by Texas civic and business leaders, environmentalists and energy consumers.
 
 The CO2 would be captured and transported via pipeline to oil fields in the 
    Permian Basin where it will be used in enhanced oil recovery and stored in 
    the Basin's geologic formations. CO2 has been used to increase oil 
    production in West Texas for more than 30 years.
 
 The volume of CO2 expected to be sold to oil producers could be used to 
    recover enough oil to add more than $1 billion a year of oil production to 
    the Texas economy.
 
 The approximately 600-megawatt (MW) plant would provide enough electricity 
    to power about 600,000 homes. Construction could begin in late 2009 and be 
    completed in 2014.
 
 Tenaska is a privately held energy company, based in Omaha, Nebraska, that 
    develops, constructs, owns and operates numerous generating plants. The 
    company has developed four generating plants in Texas and continues to own 
    and operate two, Tenaska Frontier Generating Station near Shiro and Tenaska 
    Gateway Generating Station near Mt. Enterprise. A third plant, the Tenaska 
    Kiamichi Generating Station near Kiowa, Oklahoma, also supplies electricity 
    into Texas. Tenaska's power marketing company, Tenaska Power Services Co., 
    is based in Arlington, along with Tenaska's Business Development Group.
