Last fall, the house of Bezos announced a $500 million investment in SMR startup X-Energy. On Thursday, the e-tailer revealed that X-Energy's Xe-100 SMR designs would eventually supply Washington State with "up to" 960 megawatts of clean energy. "Eventually" is the key word here as construction isn't expected to start until the end of the decade and the plants won't begin operations until sometime in the 2030s.
