To support its under-construction data centers, including in northeast Alabama, Google on Wednesday announced plans to purchase the output from the two largest solar energy farms to be built for the internet giant.

The solar farms will ensure that the electricity consumed by the data centers in Tennessee and Alabama is matched with 100 percent renewable energy from day one, according to Google.

The Alabama solar farm will be in Hollywood near Scottsboro while the Tennessee facility will be in Yum Yum near Memphis.

Google is building data centers in Bridgeport in northeast Alabama as well as Clarksville, Tenn.

Each of the solar farms will generate about 150 megawatts. Google will be purchasing the energy output from the panels that NextEra Energy Resources and Invenergy is building.

“Google’s data centers are the engines of the Internet, and we are committed to maintaining 100 percent renewable energy and achieving carbon-free energy around the clock for the operation of these facilities,” Google said in a statement. “This milestone solar energy deal with TVA perfectly reflects this strategic commitment. These renewable energy projects represent good news for Google and for the Tennessee Valley region.”

The announcement comes on the heels of plans shared last year by Facebook – which is building a data center in Huntsville -- to build a solar farm in Colbert County in northwest Alabama that will generate about 227 megawatts of electricity.

The Google data center in Alabama is expected to be online later this year.

It has promised to use renewable energy at its Alabama facility.

“Top-tier businesses like Google choose to invest in the Valley because of TVA’s diverse energy portfolio,” said John Bradley, TVA’s senior vice president of Economic Development. “Delivering large amounts of reliable, renewable energy at competitive rates creates quality jobs for the region and makes the Valley an attractive place to do business.”

Google said it will purchase the output of several new solar farms as part of a deal with TVA, totaling 413 megawatts of power from 1.6 million solar panels— the equivalent to the combined size of 65,000 home rooftop solar systems.

“TVA recognizes that renewable energy is a tremendous asset in terms of economic and environmental benefits,” said Doug Perry, TVA vice president of Commercial Energy Solutions. “We’re excited to partner with Google and make this happen for our region.”
