Amazon.com Inc. announced Aug. 1 that it has signed up to buy the output from two new renewable energy projects with a combined capacity of 68.2 MW to power its cloud computing operations in Ireland and the U.S.

The company has struck its second Irish wind farm power purchase agreement, or PPA, agreeing an off-take deal with a planned 23.2-MW wind facility located in Cork. It has also signed a PPA with a 45-MW solar plant in Pittsylvania County, Va. in a transaction that is company's seventh solar off-take in the commonwealth.

Both projects are expected to go online in 2020 and will provide the output to Amazon's cloud-based Amazon Web Services Inc. data centers. Following the two deals, Amazon's total number of renewables assets stands at 66.
