The customer is Pattern Energy Group, an independent power company based in San Francisco, Calif. The firm's portfolio is comprised of 10 wind farms.
Combined, the scope of these long-term contracts represents one of Siemens’ largest agreements with a single customer in North America.
“This is an important milestone in the continued maturation of the wind industry in North America,” said Tim Holt, CEO of Service Renewables, a business unit of the Siemens Energy Service Division, in a written statement. “As more and more wind energy is placed into service, our commitment is to provide long-term added value to customers like Pattern Energy in order to help them realize favorable performance throughout the turbines’ life cycle.”
Under the terms of the contract, Siemens will provide the long-term service and maintenance, as well as technology updates, for six Pattern Energy wind projects 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.
“As an industry leader with vast experience, Siemens brings long-term reliability and technology enhancements to our wind projects, ensuring improved performance and lower operating cost risks from each and every turbine,” said Mike Garland, president and CEO of Pattern Energy.
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.
