Northern Power Systems Wind Turbines perform through Hurricanes and Typhoons

BARRE, Vt., Oct. 12, 2016

Northern Power turbines at Over Yonder Cay in the Bahamas have now performed through three hurricanes without damage, most recently, experiencing winds of over 135 miles per hour and at least one direct lightning strike with no damage sustained.  Throughout the storm the turbines performed as designed, shutting down in high winds and restarting when conditions were safe, all without human intervention.

Gordon Scott Metcalf, Renewable Energy Engineer at Over Yonder Cay, stated, "Having seen the Northern Power turbines perform through previous hurricanes, we were confident to operate the turbines through Hurricane Matthew. The turbines performed perfectly and helped us repower the island immediately once the wind speed dropped to within the usable limits. The Northern Power service team was in constant contact with us ensuring that any support, if it had been needed, was available."

During the same timeframe, six additional Northern Power turbines were performing during Typhoon Chaba on three separate islands located off the southern coast of South Korea.  The Jeju region was one of the areas worst affected by the typhoon, which is thought to be the worst to hit the area in over a decade.  On Gasa-do, Geocha-do and Jeju-do the turbines performed as designed and without damage through winds of over 75 miles per hour.

Ciel Caldwell, Northern Power Systems President and Chief Operating Officer concluded, "Whether it is island installations or our Arctic fleet, Northern Power Systems turbines are proven to deliver in environmentally challenging remote regions.  With approximately one million run hours of proven off-grid fleet performance, our customers can have confidence that choosing a Northern Power Systems turbine for remote installation is the right decision.  Our third generation distributed wind turbine platform has been optimized for increased energy production and we now offer a tilt-up tower with installation managed by Northern Power Systems to make it even easier for remote customers to benefit from wind energy and the resulting lower diesel fuel consumption."
