Siemens, Pattern Energy Agree to Long-Term Service Contract

10-year maintenance program encompasses 400 turbines at six sites in the United States, Canada, and Puerto Rico totaling more than 930 MW


Underscoring growing customer confidence in the valuable benefits Siemens Energy can provide with its flexible, longer term wind service agreements, the company has been awarded 10-year wind service agreements encompassing over 400 onshore wind turbines in the U.S., Canada and Puerto Rico. The customer is Pattern Energy Group Inc., based in San Francisco. Combined, the scope of these long-term contracts represents one of Siemens’ largest agreements with a single customer in North America.

Pattern Energy is a leading independent power company with a portfolio of 10 wind power projects in the United States, Canada and Chile.

“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. “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’ lifecycle.”

“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.

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 (138 MW); Spring Valley Wind in eastern Nevada (152 MW); Ocotillo Wind in Southern California with (265 MW); Hatchet Ridge Wind in Northern California (101 MW); and Santa Isabel in Puerto Rico (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 (182 MW), which Pattern Energy has agreed to acquire when the project reaches operation later this year.
