Amazon Wind Farm US Central 2 will be located in Hardin County.

Annual power generation at the wind farm could reach about 2.2 million MWh of energy and the energy generated there would be equivalent in powering about 200,000 US households annually.

Amazon has entered into a contract with EverPower Wind Holdings to construct, own and operate the new wind farm.

The wind farm is expected to begin its operations by December 2017. It is AWS' fifth renewable energy project globally.

Power produced at this wind farm will be used for running AWS data centres located in the US East (Ohio) and US East (N. Virginia) Regions.

Amazon announced back in 2014 that it would reduce the energy foot print of AWS data centres by powering them with renewable energy. It had a goal of providing 40% of power to the data centres through renewables in 2016 and 50% in 2017.

AWS Infrastructure vice president, Peter DeSantis said: "We remain committed to achieving our long-term goal of powering the AWS Cloud with 100 percent renewable energy.

“There are lots of things that go into making this a reality, including governments implementing policies that stimulate cost-effective renewable energy production, businesses that buy that energy, economical renewable projects from our development partners and utilities, as well as technological and operational innovation that drives greater efficiencies in our global infrastructure.

“We continue to push on all of these fronts to stay well ahead of our renewable energy goals.”
