Microsoft Announces Biggest-Ever Wind Energy Buy
Its cloud data center in Wyoming will get clean power boost.
Microsoft on Monday said it has inked its biggest deals yet to acquire renewable wind energy to power its massive U.S. data centers.
Its two new contracts represent 237 megawatts of generating capacity, bringing Microsoft’s wind power total in the United States to more than 500 megawatts, the company said. Megawatt (or 1000 kilwatts) is a standard measurement of electricity production.
Microsoft MSFT 0.58% signed with insurance organization Allianz Risk Transfer to acquire energy from a new 178-megawatt Bloom Wind project in Kansas. The deal “fixes” its contracted energy costs over a long-term agreement. Second, it inked a long-term contract with Black Hills Energy to buy 59 megawatts of energy “certificates” related to two wind projects near Microsoft’s Cheyenne, Wyoming, data center site. The combined output of those two sites should produce enough energy per year to supply its Cheyenne facility with all the energy it needs, Microsoft said.
Cloud computing, despite its ethereal name, depends on lots of power-slurping data centers. That’s why companies like Facebook FB 0.47% , Amazon AMZN -1.77% , Google GOOG 1.61% , Salesforce.com CRM -1.02% , and Microsoft like to find—and publicize—clean or renewable energy sources. A few weeks ago, Amazon Web Services announced plans for a 189-megawatt wind power farm in Ohio slated to come online in December 2017.
Microsoft and Black Hills Energy have worked out a new tariff that will enable the energy company to, as needs dictate, use the local data center’s backup generators, thereby eliminating the need for Black Hills Energy to construct a new power plant.
