The customer is Pattern Energy Group Inc., based in San Francisco, California. Combined, the scope of these long-term contracts represents one of Siemens’ largest agreements with a single customer in North America.
Helping Pattern Energy obtain continued reliability, availability and performance of the turbines, Siemens will provide the long-term service and maintenance, as well as technology updates, for six Pattern Energy wind projects located in the U.S., Canada and Puerto Rico with a combined output of over 930 MW.
The current operating projects included in the new service agreements are Pattern Energy’s St. Joseph Wind project in southern Manitoba with 60 SWT 2.3-101 wind turbines (138 MW); Spring Valley Wind in eastern Nevada with 66 SWT-2.3-101 wind turbines (152 MW); Ocotillo Wind in Southern California with 112 SWT-2.3s-108 units (265 MW); Hatchet Ridge Wind in Northern California with 44 SWT-2.3-93 wind turbines (101 MW); and Santa Isabel in Puerto Rico with 44 SWT-2.3-108 units (101 MW).
These projects are also slated to receive a variety of modernization and upgrade components representing the latest technological advancements, such as Siemens’ Power Curve Upgrade, a combination of add-on components designed to help improve the aerodynamic performance of installed turbines.
In addition to the projects currently in operation, Siemens has also signed a 10-year service agreement for the Panhandle 2 wind project in Texas with 79 SWT-2.3-108 turbines (182 MW), which Pattern Energy has agreed to acquire when the project reaches operation later this year.
