Tesla’s vitality storage enterprise is the elder statesman, at greater than a decade previous. Progress in its Powerwall (battery storage for houses) and Megapack (battery storage for utilities and business services) gross sales has, in recent times, helped to compensate for a drop in EV sales, although final quarter noticed a sudden drop in vitality income. Nonetheless, Tesla is shifting ahead with its plans to launch a Houston facility devoted to a brand new, bigger Megapack later this 12 months.
In whole, 11 battery cell manufacturing vegetation are being retooled for vitality storage, based on a March rely by BloombergNEF, with eight of these within the US.

One cause buyers are so bullish about battery vitality storage is their continued enthusiasm for AI. AI corporations want data centers, and information facilities want vitality. Batteries are an amazing match for information facilities, says Shan Tomouk, who leads battery vitality storage analysis at Benchmark Mineral Intelligence, a analysis agency centered on battery provide chains. Batteries may help immediately energy the very energy-hungry facilities, which always run servers and different {hardware}, but additionally the cooling methods that hold them functioning.
The storage methods will also be a match for information facilities that principally depend upon different vitality sources, like natural gas. Battery vitality storage methods can function a backup energy supply if one thing goes down and may help information facilities handle giant and wild energy fluctuations associated to AI coaching. They’ll additionally kick in to assist scale back demand on the grid, decreasing prices not only for information facilities, however everybody else who depends upon the identical system—an vital upside in communities already hostile to the tech.
“If the massive market of knowledge facilities retains rising yearly, it does make sense for automakers to pivot,” Tomouk says. He expects it can. “Within the US, there’s an actual drive to construct information facilities, to keep the US as the number one when it comes to AI.”
For automakers backing away from EVs, there’s one other potential upside to battery storage, even when the pivot doesn’t fully work out. “If automakers aren’t earning money from storage and never earning money from EVs, they would like to not earn a living from storage as a result of they’re not competing with their very own fuel automotive manufacturing,” says Gil Tal, who directs the EV Analysis Heart at UC Davis’ Institute of Transportation Research. “It makes good sense, sadly.”
