Confidential memo: Wind turbine model installed at Kahuku has structural problems

By Andrew Walden, Hawaii Free Press, www.hawaiifreepress.com 6 December 2011

A confidential June, 2009 report by representatives of wind developer First Wind and wind turbine manufacturer Clipper Liberty raised questions about Clipper Liberty wind turbines sited in dozens of wind farms across the United States. Twelve Clipper Liberty turbines were installed in 2010 and early 2011 at the Kahuku Wind Farm at the northern tip of Oahu.

Described in an email, posted online by New York State officials, the confidential presentation to New York State regulators provided, “an overview of the root cause analysis undertaken by Clipper regarding the blade skin crack, an update of the resolution relating to gearbox timing, structural blade remediation, as well as other data regarding Clipper’s Liberty turbine.”

The email underlined Clipper Liberty’s insistence that the still-secret document, “is…relating to equipment design and testing of major components of the Clipper Liberty turbine, including the turbine blades, the drivetrain, and other information which is protected by Clipper, the manufacturer.” Attorney Ruth Leistensnider warned that release of the information, “could cause injury to Clipper’s competitive position.”

Clipper Liberty was founded by a former Director of Enron Wind. Clipper Liberty Vice President of Engineering is also an Enron Wind veteran.

Five months after the New York presentation, Clipper Liberty stockholders leapt at the chance to unload their shares for £1.80 ($2.81) per share offered by United Technologies.

Eleven months after the New York presentation, the Hawaii Public Utilities Commission approved a power purchase agreement between HECO and First Wind’s Kahuku Wind Power.

There is no record of any Hawaii public discussion of the Clipper Liberty blade skin crack and gearbox timing problems prior to or subsequent to the approval and construction of the Kahuku Wind Farm.
