Amazon Web Services, an on-demand cloud computing platforms and APIs provider, agreed to acquire Cumulus Data, a 960-megawatt data center campus, from Talen Energy, a power producer, for $650m. "We are pleased today to have sold our Cumulus data center campus, unlocking significant value for Talen. This transaction provides an attractive return on Talen's investment and vision in building Cumulus, and creates value through the sale of clean carbon-free power from our top-decile Susquehanna nuclear plant," Mac McFarland, Talen President and CEO.
