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 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.
Tesla Energy shined in what was a weak delivery report for the first quarter, as the company’s frequently-forgotten battery storage products performed extraordinarily well.
Tesla reported its Q1 production, delivery, and deployment figures for the first quarter of the year, and while many were less-than-excited about the automotive side, the Energy division performed well with 10.4 GWh of energy storage products deployed during the first quarter.
This was a 156 percent increase year-over-year and the company’s second-best quarter in terms of energy deployments to date. Only Q4 2024 was better, as 11 GWh was recorded.
Tesla Energy is frequently forgotten and not talked about enough. The company has continued to deploy massive energy storage projects across the globe, and as it recorded 31.5 GWh of deployments last year, 2025 is already looking as if it will be a record-setting year if it continues at this pace.

Although Energy performed well, many investors are privy to that of the automotive division’s performance, which is where some concern lies. Tesla had a weak quarter for deliveries, missing Wall Street estimates by a considerable margin.
There are two very likely reasons as to why this happened: the first is Tesla’s switchover to the new Model Y at its production facilities across the globe. Tesla said it lost “several weeks” of production due to the updating of manufacturing lines as it rolled out a new version of its all-electric crossover.
Secondly, Tesla could be facing some pressure from pushback against the brand, which is what many analysts will say. Despite the publicity of attacks on Tesla drivers and their vehicles, as well as the company’s showrooms, it would be safe to assume that we will have a better picture painted of what the issue is in Q2 after the company reports numbers in July.
If Tesla is still struggling with lackluster delivery figures in Q2 after the Model Y is ramped and deliveries are more predictable and consistent, we could see where the argument for brand damage is legitimate. However, we are more prone to believe the Model Y, which accounts for most of Tesla’s sales, and its production ramp is likely the cause for what happened in Q1.
In what was a relatively bleak quarter, Tesla Energy still shines as the bright spot for the quarter.
Tesla has chosen the location of its latest manufacturing project, a facility that will churn out the Megapack, a large-scale energy storage system for solar energy projects. It has chosen Waller County, Texas, as the location of the new plant, according to a Commissioners Court meeting that occurred on Wednesday, March 5.
Around midday, members of the Waller County Commissioners Court approved a tax abatement agreement that will bring Tesla to its area, along with an estimated 1,500 jobs. The plant will be located at the Empire West Industrial Park in the Brookshire part of town.
Brookshire also plans to consider a tax abatement for Tesla at its meeting next Thursday.
The project will see a one million square-foot building make way for Tesla to build Megapack battery storage units, according to Covering Katy News, which first reported on the company’s intention to build a plant for its energy product.
CEO Elon Musk confirmed on the company’s Q4 2024 Earnings Call in late January that it had officially started building its third Megapack plant, but did not disclose any location:
“So, we have our second factory, which is in Shanghai, that’s starting operation, and we’re building a third factory. So, we’re trying to ramp output of the stationary battery storage as quickly as possible.”

The Megapack has been a high-demand item as more energy storage projects have started developing. Across the globe, regions are looking for ways to avert the loss of power in the event of a natural disaster or simple power outage.
This is where Megapack comes in, as it stores energy and keeps the lights on when the main grid is unable to provide electricity.
Vince Yokom of the Waller County Economic Development Partnership, commented on Tesla’s planned Megapack facility:
“I want to thank Tesla for investing in Waller County and Brookshire. This will be a state-of-the-art manufacturing facility for their Megapack product. It is a powerful battery unit that provides energy storage and support to help stabilize the grid and prevent outages.”
Tesla has had a lease on the building where it will manufacture the Megapacks since October 2021. However, it was occupied by a third-party logistics company that handled the company’s car parts.
