It would be easy to dismiss Linden—which is powered by now-ubiquitous GE 7FA gas turbines and D11 steam turbines—as just another cookie-cutter combined-cycle plant. But its size (1,240 MW), key location near New York City, and use of reclaimed water for all cooling water needs makes Linden deserving of recognition as one of POWER’s Top Plants of 2006. Perhaps its most interesting story is how the project survived more than five years from groundbreaking to commissioning.
Commercial operation of PacifiCorp’s first new power plant in more than 20 years coincided with the company’s acquisition by MidAmerican Energy Holdings Company this past March. Currant Creek treads lightly on the environment, provides needed power to PacifiCorp’s eastern control area, and has demonstrated its commitment to be a good corporate citizen of the local community. By any account, Currant Creek is a model for how to develop a power project.
The Brooklyn Navy Yard Cogeneration facility supplies critical electricity and steam to New York City. Situated on an historic site, the plant has earned a series of awards and was the first cogeneration plant to be accepted into both the U.S. EPA National Environmental Performance Track and OSHA’s Voluntary Protection Program in 2005. Through Delta Power’s unique asset management approach that brings added value to projects, BNYC has reinvented itself from a struggling, prematurely aging facility into one of the nation’s leading plants.
A great location, a fish-friendly cooling system, and the extent of environmental remediation needed to permit it distinguish this repowering project on the Hudson River just south of the New York State capital.
Iberdrola is rapidly making a name for itself on the world stage for building large, very efficient combined-cycle plants and for being the largest owner and operator of wind power plants. The utility’s most recent achievement was the successful commissioning of the Arcos de la Frontera Group III project, which marks the commercial debut of General Electric’s Frame 9FB gas turbine.

Duct burners use supplementary firing to increase the heat energy of a gas turbine’s exhaust, making it possible to increase the output of a downstream heat-recovery steam generator (HRSG). Early systems of the 1960s took a conventional approach to burner design. The exhaust of the turbine was directed into a windbox and then into a […]
Three years ago, an article in POWER described how Cheng Power Systems, by modifying the combustors of several popular gas turbines, had used steam injection to lower the units’ NOx output to about 5 ppm—but some models had substantial CO levels without combustor modifications. Since then, the company has developed new combustor nozzles that recently […]

In late February, the largest gas turbine ever manufactured by GE Energy at its Belfort plant in France began a 30-day journey by land and sea that will take it to a new power plant in Spain. The Frame 9FB gas turbine—which is also the first built completely in Belfort—was loaded onto a special, wide-load […]
