The return of the Clipper Liberty wind turbine

The Steel Winds project in Lackawanna, New York, was selected as a POWER 2007 Top Plant because of its unusual location (a former steel mill and Superfund site) and because it was the first commercial deployment of the Clipper Windpower 2.5-MW turbine. That report was written just as the project entered commercial service but before [...]

San Cristobal Wind Project, Galapagos Islands, Ecuador

The Galapagos Islands, home of the unusual flora and fauna that inspired naturalist Charles Darwin’s groundbreaking work on evolution, are striving to promote clean energy that protects the area’s unique biodiversity.Part of that effort is the 2.4-MW San Cristobal Wind Project, which displaces diesel-powered electricity generation. This new energy source will cut greenhouse gas emissions [...]

Repairing low-pressure rotors with cracked blade attachments

An increasing number of low-pressure steam turbines—especially at supercritical fossil units—have experienced stress corrosion cracking in the blade attachment region of their low-pressure rotors. Approaches to solving this problem range from redesign of the attachment and blade replacement to in-situ weld repair. Regardless of the procedure selected, the solution must completely restore the turbine performance [...]
