A few decade in the past, Tesla entered its solar-for-homes period with its contentious acquisition of SolarCity.
Now, Tesla’s photo voltaic desires are taking a special form as the corporate enters its AI era.
Tesla has inked two long-term agreements to buy energy from utility-scale photo voltaic tasks totaling about 600 megawatts of deliberate capability.
ContourGlobal, a worldwide energy producer, introduced on Tuesday that Tesla signed a long-term settlement to buy 1 terawatt-hour of electrical energy a yr from Mission Sterling, ContourGlobal’s photo voltaic and battery storage undertaking in Arizona. The deal covers about 90% of the undertaking’s anticipated output — roughly sufficient electrical energy to energy about 100,000 US houses a yr.
Renewable-energy developer Zelestra individually introduced Tuesday that Tesla would buy the whole output of its 140-megawatt Lumen Farm photo voltaic undertaking in northeast Texas. Zelestra CEO Phil North mentioned in a press release that the undertaking will assist Tesla’s “rising power wants in Texas.”
The offers replicate Elon Musk’s newest arc from leveraging solar energy for client houses to photo voltaic use in industrial settings, which may embrace AI infrastructure.
Tesla’s humble $2.6B photo voltaic beginnings
When the CEO proposed shopping for SolarCity, a rooftop photo voltaic installer and financier, in 2016, Musk framed the $2.6 billion deal as a option to create a seamless, end-to-end answer combining photo voltaic power, battery storage, and EVs.
“Tesla prospects can drive clear vehicles they usually can use our battery packs to assist eat power extra effectively, however they nonetheless want entry to essentially the most sustainable power supply that is obtainable: the solar,” Tesla mentioned on the time.
The rooftop photo voltaic enterprise did not disappear. Tesla mentioned in its first-quarter shareholder replace in April that it had begun “significant buyer deployments” of residential photo voltaic panels produced at its New York Gigafactory. Tesla additionally continues to promote Powerwall batteries for houses.

In recent times, nonetheless, Musk has more and more centered his photo voltaic ambitions on the grid, as AI is anticipated to drive surging energy demand and Tesla stakes extra of its future on AI and robotics.
Tesla’s AI guess depends on the solar
Tesla has warned traders that knowledge facilities supporting its AI companies and merchandise can have “substantial energy necessities.”
The corporate mentioned in April that it anticipated 2026 capex to exceed $25 billion because it builds factories and infrastructure for tasks together with its Robotaxi enterprise and the Optimus humanoid robotic. Each ventures rely upon large-scale AI coaching infrastructure. Tesla additionally plans to construct a semiconductor analysis fab as a part of its lengthy shot chip manufacturing ambitions.
Musk has concurrently been elevating the stakes for industrial solar energy amid the AI growth. In a January earnings name, the CEO mentioned “the photo voltaic alternative is underestimated,” and that photo voltaic paired with batteries was the “greatest approach” so as to add extra energy to the grid.
Throughout Tesla’s latest earnings call, on July 22, Musk mentioned hyperscalers are struggling to safe sufficient electrical energy for AI compute, necessitating different power sources.
“There’s much more energy obtainable from the solar than anything, by far,” Musk mentioned. “We predict energy constraints are going to be — they already are — a serious challenge for AI.”
The 2 newest photo voltaic offers make Tesla a serious purchaser of utility-scale solar power. The EV maker has dedicated to buying almost all of Mission Sterling’s annual electrical energy output and all of Zelestra’s Lumen Farm output.
ContourGlobal mentioned industrial operations are anticipated to start out in 2028 and that Sterling would be the firm’s “largest renewable asset so far.” Zelestra mentioned it expects full operations to start out by 2029.
Neither settlement recognized which Tesla operations the ability purchases will precisely assist. Spokespeople for ContourGlobal, Zelestra, and Tesla didn’t reply to requests for remark.
As Musk’s broader arc in photo voltaic power has come into focus, photo voltaic is now not powering solely houses and vehicles but additionally the infrastructure of an AI-driven future.
