Amazon joins the massive nuclear celebration, shopping for 1.92 GW for AWS
Amazon tapped into an rising development this week, one which’s seeing massive tech corporations purchase energy from current nuclear energy vegetation.
The tech firm will energy a piece of its AWS cloud and AI servers utilizing 1.92 gigawatts of electrical energy from Talen Power’s Susquehanna nuclear energy plant in Pennsylvania. Amazon is the most recent hyperscaler to go direct to massive nuclear operators, following on the heels of Microsoft and Meta.
Amazon’s deal was introduced Wednesday, nevertheless it’s not completely new, as a substitute modifying an current association with Talen. The previous model had Amazon constructing a knowledge heart subsequent to the Susquehanna energy plant, siphoning electrical energy immediately from the power with out first sending it to the grid.
That deal was killed by regulators over issues that prospects would unfairly shoulder the burden of working the grid. In the present day, Susquehanna gives energy to the grid, which means each kilowatt-hour contains transmission charges that help the grid’s upkeep and growth. Amazon’s behind-the-meter association would have sidestepped these charges.
This week’s revisions shift Amazon’s energy buy settlement in entrance of the meter, which means the AWS information heart might be billed like different related prospects who’re grid-connected. The transmission traces might be reconfigured in spring of 2026, Talen mentioned, and the deal covers power bought by way of 2042.
However wait, there’s extra: The 2 corporations additionally mentioned they may look to construct small modular reactors “inside Talen’s Pennsylvania footprint” and increase technology at current nuclear energy vegetation.
Increasing current energy vegetation is usually a better approach so as to add new nuclear. They could embrace switching to extra extremely enriched gasoline to produces extra warmth, tweaking the settings to squeeze out extra energy, or renovating the generators for a much bigger bump.
Microsoft kicked off the development final yr when it introduced that it might work with Constellation Power to restart a reactor at Three Mile Island, a $1.6 billion mission that can generate 835 megawatts. Meta hopped aboard earlier this month, additionally with Constellation, to purchase the “clear power attributes” of a 1.1 gigawatt nuclear energy plant in Illinois.
Amazon and Talen’s pledge to construct new small modular reactors is an extended shot, although there, too, Amazon is in good firm with its friends. A number of startups pursuing the idea with the hopes of reducing building prices by mass producing components. Amazon has invested in an SMR startup, X-energy, which is planning so as to add 300 megawatts of nuclear producing capability within the Pacific Northwest and Virginia.
New technology at current reactors and new SMRs are meant “so as to add net-new power to the PJM grid,” Talen mentioned, referring to the area’s grid operator. That final bit is probably going a bid to go off any criticism from regulators about leaving ratepayers holding the bag.
