Tenaska Moves Ahead with Six U.S. Power Plant Projects

---

Researched by Industrial Info Resources (Sugar Land, Texas)--Tenaska Incorporated (Omaha, Nebraska) is moving ahead with the development of six U.S. power plants. Pennsylvania and Texas each will see two Tenaska projects, and California and Indiana each will have one project, for a total capacity of 4,447 megawatts (MW). This combined total could power more than 4 million homes.

Pennsylvania
The Pennsylvania projects include the Westmoreland County Generating Station and the Lebanon County Power Station. Both are natural gas-fired, combined-cycle projects, and each would have a generation capacity of 950 MW and a total investment value (TIV) of $1.1 billion. The planned start of construction for the Westmoreland County Generating Station is mid-2015, and the plant should be operating by August 2017. The planned start of construction for Lebanon Valley Power Station is mid-2016, and that plant should be operating by August 2018.

Both the Westmoreland County Generating Station and the Lebanon County Power Station will have three 185-MW, natural gas-fired combustion turbine generators, each with supplemental-fired heat recovery steam generators to drive one 385-MW steam turbine generator. The combustion turbine generators will be from General Electric (NYSE:GE) (Fairfield, Connecticut), Siemens AG (NYSE:SI) (Munich, Germany), Mitsubishi Heavy Industries (MHI) (Tokyo, Japan), or equivalent.

Texas
In Texas, the Tenaska Roans Prairie Generating Station will have an output of 697 MW, while the Tenaska Brownsville Generating Station will have an output of 800 MW. Both Texas projects are proposed as natural gas-fired power plants, with Roans Prairie planned as a peaking station and Brownsville as a two-on-one combined-cycle project. Construction start dates are March 2017 for Tenaska Roans Prairie and June 2015 for Tenaska Brownsville, with completion in December 2019 and August 2018, respectively.

The $800 million Brownsville plant will use two 267-MW Mitsubishi 501GAC combustion turbine generators with duct-fired heat recovery steam generators, and a 266-MW Toshiba (Tokyo) steam turbine generator. The $607 million Roans Prairie will use three 232-MW Siemens SGT6-5000F, General Electric 7FA.05, or General Electric 7FA.04 simple-cycle combustion turbines.

Indiana
Coming in with a generation capacity of 900 MW is Tenaska's Blue River Power Station in Morristown, Indiana. This $500 million project also is a natural gas-fired, combined-cycle power plant, but still is almost two years away from construction, with a planned completion in September 2018. Because the project is still a long way off, the exact configuration and selection of technology providers have not yet been finalized.

California
The Tenaska project in California is a solar photovoltaic power plant with a planned capacity of 150 MW. Construction would be completed in March 2016. Soitec (Grenoble, France) is the panel provider for the $450 million project, which will use Concentrix concentrated photovoltaic (CPV) solar panels, with a ground-mounted single-axis tracking system.
