Siemens to supply data center of Amazon Web Services with clean energy

  • Wind turbines and transformers for Amazon Wind Farm (Fowler Ridge) project in the US
  • 150-megawatt project of Pattern Energy will supply electricity for the Amazon Web Services data center
  • Siemens Financial Services to provide USD 150 million of construction financing

Wind power for the Amazon Web Services Data Center - Siemens will provide 65 wind turbines of the type SWT-2.3-108 for Pattern Energy's Fowler Ridge project in Indiana.

Siemens will supply 65 wind turbines and 67 transformers for the Amazon Wind Farm (Fowler Ridge). The customer for this onshore project in Indiana is Pattern Energy.

With a capacity of 150 megawatts, the wind power plant will provide Amazon Web Services' data center with eco-friendly electricity. Installation is scheduled to begin in July. Commissioning is planned for the first quarter of 2016. Siemens will also be providing long-term service for the wind turbines.

"US technology companies such as Amazon are increasingly covering their rising energy demands with clean wind-based power," stated Thomas Richterich, CEO of the Unit Onshore markets within the Siemens Wind Power and Renewables Division.

"We are pleased to be part of this, together with our customer over many years, Pattern Energy, to render wind power sustainable and affordable." Only at the end of last year did Amazon pledge to run its data centers throughout the world with power from renewable energy sources.

In addition to the wind turbines, the associated service and delivery of transformers, Siemens Financial Services (SFS) will also be providing USD 150 million of construction financing for Fowler Ridge. It was, above all, the early involvement of SFS in the structuring of an innovative financing solution which contributed decisively to successful closing of the Siemens order and enabled Pattern to continue with the project.

The model SWT-2.3-108 wind turbines each have a capacity of 2.3 MW and a rotor diameter of 108 meters. The nacelles for this project will be assembled in Hutchinson, Kansas. Rotor blades for the turbines are manufactured in Fort Madison, Iowa. The Mount Generation Step up (GSU) transformers for the project are produced in the Siemens plant located in Jackson, Mississippi.
