Just recently, Tesla rolled out a subtle update to its official website. After welcoming the site’s visitors with its electric vehicle lineup for years, tesla.com now primarily showcases Tesla Energy products, represented by a header image featuring a home with solar panels and Powerwall batteries. The update was simple, but the company’s message was clear: Tesla Energy’s time to shine in the spotlight as arrived. The time to push battery storage and solar solutions into the mainstream market is now.
Tesla is known more as an electric vehicle manufacturer, and for good reason. The company owes its existence to the original Tesla Roadster, a small sports car that was built on a Lotus platform that broke mainstream conventions about what an electric car could be like. But the company’s mission as per CEO Elon Musk has always been clear: Tesla exists to accelerate the world’s transition to sustainability. And it just so happens that electric vehicles cannot get the job done alone.
During a previous interview with Teslarati, Robert Bollinger, the founder of Bollinger Motors, a maker of off-road, rough-and-tough EV trucks and pickups, stated that any new automaker today has to be focused on electric cars. And he’s absolutely right. It may not be universally acknowledged outright, but the automotive industry knows that electric vehicles are the way to go in order to survive the future. Full stop.
It might be a strange idea today, but there was once a time when electric vehicles were not taken seriously by the motoring industry at all. With the Model S, Model 3, Model X, and now the Model Y, Tesla has essentially pulled the automotive sector towards electric transportation kicking and screaming. After years of empty EV promises, unnecessarily complex electric concept cars that will never get mass produced, and sweet-talking statements about commitments to a zero-emissions future, legacy auto simply cannot stand by and maintain its old stance. It simply cannot afford to if it wants to survive.
The same has not happened yet to the utility sector. Renewables are on the rise, and climate action awareness is gaining ground. But overall, the idea of utilities being powered by renewables and giant batteries is still widely considered as niche ideas for now. The fossil fuel industry is still very prominent in the energy sector, and thus, the battle for sustainability on this front is only just beginning — and it will be very, very difficult. If the automotive sector was pulled into EVs kicking and screaming, the energy sector, which is dominated by the fossil fuel industry, will likely fight even harder.
This is something that supporters of Tesla and those that follow the company have to keep in mind. Tesla has struggled with misinformation for over a decade thanks to short-sellers and skeptics who simply don’t believe in electric cars or the company’s specific approach to EVs. It would thus be wise to brace for the upcoming challenges that will be brought about by Tesla quite literally taking on the fossil fuel industry, and in an arena that it has dominated for a very long time.
Fortunately, Tesla is now a mature company with an equally mature technology. Its battery tech is also second to none, as evidenced by the upcoming announcements for its highly-speculated million-mile battery. These, together with the support of an electric car business that is now the largest in the automotive industry by market cap, may very well give Tesla Energy enough power to disrupt, and eventually transition, the utility sector towards sustainability.

Tesla Lathrop Megafactory celebrates massive Megapack battery milestone
The Tesla Megapack is the backbone of Tesla Energy’s battery deployments.

The Tesla Lathrop Megafactory recently achieved a new milestone. As per the official Tesla Megapack account on X, the Lathrop Megafactory has produced its 15,000th Megapack 2 XL battery.
15,000 Megapack Batteries
Tesla celebrated the milestone with a photo of the Lathrop Megafactory team posing with a freshly produced Megapack battery. To commemorate the event, the team held balloons that spelled out “15,000” as they posed for the photo.
The Tesla Megapack is the backbone of Tesla Energy’s battery deployments. Designed for grid-scale applications, each Megapack offers 3.9 MWh of energy and 1.9 MW of power. The battery is extremely scalable, making it perfect for massive energy storage projects.
More Megafactories
The Lathrop Megafactory is Tesla’s first dedicated facility for its flagship battery storage system. It currently stands as the largest utility-scale battery factory in North America. The facility is capable of producing 10,000 Megapack batteries every year, equal to 40 GWh of clean energy storage.
Thanks to the success of the Megapack, Tesla has expanded its energy business by building and launching the Shanghai Megafactory, which is also expected to produce 40 GWh of energy storage per year. The ramp of the Shanghai Megafactory is quite impressive, with Tesla noting in its Q1 2025 Update Letter that the Shanghai Megafactory managed to produce over 100 Megapack batteries in the first quarter alone.
Tesla Energy’s Potential
During the first quarter earnings call, CEO Elon Musk stated that the Megapack is extremely valuable to the energy industry.
“The Megapack enables utility companies to output far more total energy than would otherwise be the case… This is a massive unlock on total energy output of any given grid over the course of a year. And utility companies are beginning to realize this and are buying in our Megapacks at scale,” Musk said.

Tesla Megapacks powers the xAI Colossus supercomputer
Tesla Megapacks step in to stabilize xAI’s Colossus supercomputer, replacing natural gas turbines. Musk’s ventures keep intertwining.

Tesla Megapack batteries will power the xAI Colossus supercomputer in Memphis to ensure power stability. The collaboration between Tesla and xAI highlights the synergy among Elon Musk’s ventures.
The artificial intelligence startup has integrated Tesla Megapacks to manage outages and demand surges, bolstering the facility’s reliability. The Greater Memphis Chamber announced that Colossus, recently connected to a new 150-megawatt electric substation, is completing its first construction phase. This transition addresses criticism from environmental justice groups over the initial use of natural gas turbines.
“The temporary natural gas turbines that were being used to power the Phase I GPUs prior to grid connection are now being demobilized and will be removed from the site over the next two months.
“About half of the operating turbines will remain operating to power Phase II GPUs of xAI until a second substation (#22) already in construction is completed and connected to the electric grid, which is planned for the Fall of 2025, at which time the remaining turbines will be relegated to a backup power role,” the Chamber stated.
xAI’s rapid development of Colossus reflects its ambition to advance AI capabilities, but the project has faced scrutiny for environmental impacts. The shift to Megapacks and grid power aims to mitigate these concerns while ensuring operational continuity.
The Megapack deployment underscores the collaboration among Musk’s companies, including Tesla, SpaceX, Neuralink, and The Boring Company. Tesla appears to be the common link between all of Musk’s companies. For example, The Boring Company built a tunnel in Giga, Texas. In addition, Musk has hinted at a potential collaboration between the Tesla Optimus Bot and Neuralink. And from January 2024 to February 2025, xAI invested $230 million in Megapacks, per a Tesla filing.
Tesla Energy reported a 156% year-over-year increase in Q1 2025, deploying 10.4 GWh of storage products, including Megapacks and Powerwalls. Tesla’s plans for a new Megapack factory in Waller County, Texas, which is expected to create 1,500 jobs in the area, further signal its commitment to scaling energy solutions.
As xAI leverages Tesla’s Megapacks to power Colossus, the integration showcases Musk’s interconnected business ecosystem. The supercomputer’s enhanced stability positions xAI to drive AI innovation, while Tesla’s energy solutions gain prominence, setting the stage for broader technological and economic impacts.

Tesla Energy celebrates one decade of sustainability
Tesla Energy has gone far since its early days, and it is now becoming a progressively bigger part of the company.

Tesla Energy recently celebrated its 10th anniversary with a dedicated video showcasing several of its milestones over the past decade.
Tesla Energy has gone far since its early days, and it is now becoming a progressively bigger part of the company.
Tesla Energy Early Days
When Elon Musk launched Tesla Energy in 2015, he noted that the business is a fundamental transformation of how the world works. To start, Tesla Energy offered the Powerwall, a 7 kWh/10 kWh home battery system, and the Powerpack, a grid-capable 100 kWh battery block that is designed for scalability. A few days after the products’ launch, Musk noted that Tesla had received 38,000 reservations for the Powerwall and 2,500 reservations for the Powerpack.
Tesla Energy’s beginnings would herald its quiet growth, with the company later announcing products like the Solar Roof tile, which is yet to be ramped, and the successor to the Powerwall, the 13.5 kWh Powerwall 2. In recent years, Tesla Energy also launched its Powerwall 3 home battery and the massive Megapack, a 3.9 MWh monster of a battery unit that has become the backbone for energy storage systems across the globe.
Key Milestones
As noted by Tesla Energy in its recent video, it has now established facilities that allow the company to manufacture 20,000 units of the Megapack every year, which should help grow the 23 GWh worth of Megapacks that have already been deployed globally.
The Powerwall remains a desirable home battery as well, with more than 850,000 units installed worldwide. These translate to 12 GWh of residential entry storage delivered to date. Just like the Megapack, Tesla is also ramping its production of the Powerwall, allowing the division to grow even more.
Tesla Energy’s Role
While Tesla Energy does not catch as much headlines as the company’s electric vehicle businesses, its contributions to the company’s bottom line have been growing. In the first quarter of 2025 alone, Tesla Energy deployed 10.4 GWh of energy storage products. Powerwall deployments also crossed 1 GWh in one quarter for the first time. As per Tesla in its Q1 2025 Update Letter, the gross margin for the Energy division has improved sequentially as well.
