Under the terms of the sale, Amazon not only acquired Cumulus' datacenter facilities and associated power infrastructure, but has direct — behind the meter — access to a sizable chunk of the energy generated by the nuclear plant's two reactors.

Over the course of its contract with Talen, Amazon expects to unlock upwards of 960 MW of power supply. However, we'll note that the cloud titan has the option to cap this at 480 MW if it doesn't actually need all of it.

We've now learned at least 15 new datacenters will be built adjacent and connected to the fission plant over the next ten years. As we've previously reported, an AWS campus with five buildings may take up 600,000 square feet, or around 13 acres, and capacity of between 50 and 60 megawatts. //

As generative AI has taken off, it's not uncommon to see clusters of 20,000 or more GPUs capable of consuming in excess of 25 megawatts of power, deployed.
