The service agreement with Vestas is for 429MW of capacity in Washington state.

The three wind farms feature 214 V80-1.8 and 22 V80-2.0 MW wind turbines.

PSE director of wind resources and asset management John Mannetti said:"PSE is excited to continue our excellent partnership with Vestas.

"They’ve serviced these sites from the beginning of our wind program, and we’re glad they’ll be continuing to work with us as our assets progress through their lifecycle."

Puget Sound Energy is one of the largest utility owners of wind power in the US, in addition to being the largest utility producer of renewable energy in the Pacific Northwest.

Vestas provided services at all three sites since their commissioning while the extended deal includes a time-based availability guarantee that supports optimal turbine utilization and productivity.

The service contract includes the Vestas Active Output Management (AOM) 4000.

Vestas sales and service division president in the US and Canada Chris Brown said: "Extending this service contract speaks to the strong partnership between Vestas and Puget Sound Energy. Since 2005, we have provided world-class service for their fleet of Vestas wind turbines."

By the end of the third quarter of 2014, Vestas had installed 11,879MW of turbines in the US.
