Digital Realty is expanding its renewable energy and sustainability initiatives with two long-term power purchase agreements to source approximately 324,000 additional MWh of renewable wind and solar power annually for the company's Chicago and Ashburn data center properties. The output will supply Digital Realty's newly expanded Clean Start2Program, which makes renewable energy available to customers interested in procuring net-new, locally produced renewable energy through their data center supplier.
The first agreement, with Leeward Renewable Energy, an affiliate of ArcLight Capital Partners, will supply the company’s Chicago data centers with an anticipated 276,000 MWh of wind power annually.
Leeward Renewable Energy Chief Executive Officer Greg Wolf, said, "We are happy to support Digital Realty's sustainability efforts through the long-term Power Purchase Agreement from our first-of-its-kind repowering project in Lee County. We look forward to a long and healthy relationship with Digital Realty as we continue to serve clean energy customers in this growing market."
The second agreement, with SunEnergy1, will supply the company’s Ashburn data centers with 48,000 MWh of solar power annually. Both projects are expected to come online in 2018. Digital Realty was assisted in the contracting process by advisory firm Schneider Electric-Renewable Choice Energy.
The agreements will increase the quantity of renewable energy sourced for the company's owned and managed data centers in the U.S. by 80 percent. Following the expansion, Digital Realty will have contracted for approximately 721,000 MWh of renewable generation annually through long-term contracts, avoiding approximately 515,000 metric tons of carbon dioxide per year.
"We are committed to minimizing the impact of our operations on the environment, and to supplying our customers the sustainable solutions they want," said Digital Realty Chief Executive Officer A. William Stein.
