Siemens has been awarded a contract to provide service and maintenance for an additional 10 years at Pudget Sound Energy’s 343MW Lower Snake River wind project in Washington State, USA.

The deal follows up on an alliance announced last week between the German industrial conglomerate and Duke Energy Renewable Services.

The 149 Siemens SWT-2.3-101 turbines of the wind park have been serviced and maintained by Siemens since commercial operations began in 2012.
