Siemens wins ten-year O&M extension

UNITED STATES: Siemens has extended its servicing contract at the 343MW Lower Snake River project in Washington, north-west US, for a further ten years.

The Puget Sound Energy project in Washington was completed in 2012

The Puget Sound Energy project, installed in Garfield County, south-east Washington, was completed in 2012 and comprises 149 Siemens SWT-2.3-101 turbines.

Siemens will continue to service the projects, as it has done since it was commissioned.

It will also install a power boost upgrade and a high-wind retrofit to all of the turbines to avoid complete shutdown of the machines in wind speeds over 25m/s.

The manufacturer expects the upgrade could increase yield by 4% in certain site conditions, it said.

The extension comes a week after Siemens announced an operating and maintenance North American partnership with developer Duke Energy.
