How ​AWS is powering up its wind farm plans for cloud datacenters

As part of its renewable energy ambitions, Amazon Web Services has signed a deal to buy most of the power generated by an Indiana wind farm for its US datacenters.

Amazon Web Services says a new Indiana wind farm could be helping power its datacenters by as early as January 2016.

The 150MW farm in Benton County, Indiana, which is being built by the Pattern Energy Group, is expected to generate about 500,000MWh of electricity annually.

"Amazon Web Services Wind Farm, Fowler Ridge, will bring a new source of clean energy to the electric grid where we currently operate a large number of datacenters and have ongoing expansion plans to support our growing customer base," AWS infrastructure VP Jerry Hunter said in a statement.

He said the power-purchase agreement with Pattern Energy will help increase the renewable energy used to run AWS' US infrastructure.

"[It] is one of many sustainability activities and renewable energy projects for powering our datacenters that we currently have in the works," he said.

The company already uses a number of renewable energy sources for its datacenter infrastructure, including wind, hydro, and solar.

In November 2014, AWS set out plans to use only renewable energy for its global infrastructure. To date, the company has three carbon-neutral regions: the US GovCloud, US West in Oregon, and EU in Frankfurt am Main.

As well as datacenters in the US and Germany, AWS has sites in Australia, Brazil, China, Ireland, Japan, and Singapore. The company describes its worldwide customer base as consisting of more than a million organisations, which buy its cloud-based compute, storage, database, analytics, application, and deployment services.

According to AWS, the power the wind farm should generate for its datacenters is the equivalent to that consumed by about 46,000 US homes in a year.
