Tesla’s Megapack platform is reportedly designed to absorb that kind of volatility at the interconnection point, providing fast-responding support that helps maintain stable voltage and frequency without relying on mechanical generators. The company claims Megapack can reduce AI-induced power oscillations by up to 90%, although it has not yet disclosed details on how these figures were measured or what system sizes were involved. Tesla also says the Megapack is good for $50B/GW for a 2-hour system over a 20-year lifetime, a claim it says makes the unit "outsized value" for AI data centers.
Megapack also comes as utilities begin processing a wave of record-setting interconnect requests tied to AI infrastructure buildouts. According to reporting in May, PG&E, California’s largest electric utility company, has seen a more than 40% jump in requests for power supplies from data center developers this year, with AI campuses driving much of the increase. Tesla's ability to ship battery systems rapidly may appeal to developers waiting for capacity amid long lead times for new transmission and substation projects.
Tesla previously introduced Megapack 3 and a new prefabricated enclosure platform called Megablock in September, with production scaling up at a dedicated facility in Houston, Texas. These systems integrate power electronics and thermal controls into modular units designed for faster site deployment and lower total cost, particularly where space and time constraints make traditional substation upgrades impractical.
As AI training loads continue to evolve, questions remain about how battery systems like Megapack will be integrated into existing data center electrical topologies. It is not yet clear whether the systems will be deployed as part of UPS infrastructure, as front-of-meter grid support, or in some hybrid role. More broadly, the economics of these deployments — particularly in terms of demand charges — have yet to be disclosed.
