Tesla’s expansion of product offerings shows that a major expansion is in the making
Over the recent weeks, Tesla appears to be setting the stage for an intensive expansion of its product offerings. From the United States to China, the company seems to be intent on pursuing more and more avenues for its electric car and energy business. This hints at one thing: a major expansion is underway, and the all-too challenging battery supply code has been cracked.
Tesla CEO Elon Musk is known for his grand and ambitious dreams. If it were up to Musk, the world would completely abandon fossil fuels and dedicate a part of its resources to exploring interplanetary solutions. But Tesla, one of Musk’s two main businesses, is heavily reliant on batteries. No matter how much Tesla or Musk would want to accelerate the ramp towards sustainability, the proverbial battery supply problem has to be solved first.
This was highlighted by Musk in a previous earnings call last year. When asked about the Tesla Semi, a Class 8 truck that was initially set to begin deliveries in 2019 but was subsequently delayed, Musk explained that the vehicle could not be ramped fully unless the issue of battery cell supply is addressed. After all, the Semi is a massive vehicle, and it uses a lot of cells.

This sentiment is pretty much universal across Tesla’s lineup, including its Energy business and in products like the humble Powerwall and the grid-scale Megapack. Longtime followers of Tesla would remember that during the height of the Model 3’s production hell, Tesla ended up using lines that were allotted for the Powerwall’s cells to produce batteries for the electric sedan instead. This resulted in delays for the home battery storage unit.
But things today are much different than before. Amidst the impending announcements for Battery Day, reports are abounding that the company is poised to reveal the latest innovations in its battery tech. Among these is a million-mile battery, which would be resilient enough to outlast the internal combustion engine when used in electric cars and durable enough to last decades if deployed as battery storage.
These breakthroughs could change everything for Tesla, and it would allow the company to expand at a rate that exceeds its already rapid growth over the years. Tesla has been providing hints about the stages of this growth, from the rollout of China-made Model 3s that are equipped with batteries that have no cobalt content, the highly-anticipated production ramp of the Semi, the aggressive timeframe for the Cybertruck, renewed battery cell deals with Panasonic, to its recent permit to become a utility provider in the United Kingdom.

Each of these projects would not be possible unless the company has cracked the code on battery cell technology and production. Today, all signs are pointing to this very scenario. This should ultimately be validating for the company and its executives, considering that it has attracted a notable amount of criticism and mockery over the years due to its intense focus and pursuit of next-generation battery tech.
Back in 2014, after all, even the MIT Technology Review noted that there is little sense in an endeavor like Gigafactory Nevada, since Tesla’s car sales then did not warrant such a demand for batteries. Critics then also argued that it would be better for Tesla to just work with existing battery manufacturers. Interestingly, ARK Invest, one of Tesla’s most ardent bulls, was one of the few that actually believed in the value of Gigafactory Nevada in 2014, stating that it while ambitious, the company’s plans for the facility are actually feasible.

Tesla starts hiring efforts for Texas Megafactory
Tesla’s Brookshire site is expected to produce 10,000 Megapacks annually, equal to 40 gigawatt hours of energy storage.
Tesla has officially begun hiring for its new $200 million Megafactory in Brookshire, Texas, a manufacturing hub expected to employ 1,500 people by 2028. The facility, which will build Tesla’s grid-scale Megapack batteries, is part of the company’s growing energy storage footprint.
Tesla’s hiring efforts for the Texas Megafactory are hinted at by the job openings currently active on the company’s Careers website.
Tesla’s Texas Megafactory
Tesla’s Brookshire site is expected to produce 10,000 Megapacks annually, equal to 40 gigawatt hours of energy storage, similar to the Lathrop Megafactory in California. Tesla’s Careers website currently lists over 30 job openings for the site, from engineers, welders, and project managers. Each of the openings is listed for Brookshire, Texas.
The company has leased two buildings in Empire West Business Park, with over $194 million in combined property and equipment investment. Tesla’s agreement with Waller County includes a 60% property tax abatement, contingent on meeting employment benchmarks: 375 jobs by 2026, 750 by 2027, and 1,500 by 2028, as noted in a report from the Houston Business Journal. Tesla is required to employ at least 1,500 workers in the facility through the rest of the 10-year abatement period.
Tesla’s clean energy boom
City officials have stated that Tesla’s arrival marks a turning point for the Texas city, as it highlights a shift from logistics to advanced clean energy manufacturing. Ramiro Bautista from Brookshire’s economic development office, highlighted this in a comment to the Journal.
“(Tesla) has great-paying jobs. Not just that, but the advanced manufacturing (and) clean energy is coming to the area,” he said. “So it’s not just your normal logistics manufacturing. This is advanced manufacturing coming to this area, and this brings a different type of job and investment into the local economy.”

Tesla and Samsung SDI in talks over new US battery storage deal: report
The update was related by industry sources and initially reported by South Korean news outlets.
Recent reports have suggested that Tesla and Samsung SDI are in talks over a potential partnership to supply batteries for large-scale energy storage systems (ESS).
The update was related by industry sources and initially reported by South Korean news outlets.
ESS batteries to be built at Samsung’s Indiana plant
As noted in a report from Korea JoongAng Daily, the demand for energy storage systems has been growing rapidly in North America, thanks in no small part to the surge in AI investments across numerous companies. With this in mind, Tesla has reportedly approached Samsung SDI about a potential battery supply deal.
The deal is reportedly worth over 3 trillion Korean won (approximately $2.11 billion) and will span three years, according to The Korea Global Economic Daily. A battery supply deal with Samsung SDI could make sense for Tesla as the company already has a grid-scale battery, the Megapack, which is perfect for industrial use. Samsung SDI could simply supply cells for the EV maker.
Production of the batteries would reportedly take place at Samsung SDI’s joint venture factory with Stellantis in Indiana, which is currently under construction. Samsung SDI recently announced plans to use part of that plant’s EV lines to produce cells for ESS, with a targeted capacity of 30 GWh by the end of next year.
Tesla and Samsung’s partnership
At present, only a handful of manufacturers, including Korea’s LG Energy Solution, Samsung SDI, SK On, and Japan’s Panasonic, are capable of producing energy storage-scale batteries domestically in the United States. A Samsung SDI official issued a comment about the matter, stating, “Nothing has been finalized regarding cooperation with Tesla.”
The possible energy storage system deal adds another layer to Tesla’s growing collaboration with Samsung, which is already in line as a partner in the upcoming production of Tesla’s AI5 and AI6 chips. Early sample manufacturing of the AI6 is expected to begin in South Korea, with mass production slated for Samsung’s Texas-based Taylor foundry when it starts operations.
The AI6 chip will power Tesla’s next wave of high-volume projects, including the Optimus humanoid robot and the autonomous Cybercab service. Musk has called the partnership with Samsung a “real collaboration,” adding that he personally plans to “walk the line” at the Taylor facility to speed up progress.

Tesla VP hints at Solar Roof comeback with Giga New York push
The comments hint at possible renewed life for the Solar Roof program, which has seen years of slow growth since its 2016 unveiling.
Tesla’s long-awaited and way underrated Solar Roof may finally be getting its moment. During the company’s Q3 2025 earnings call, Vice President of Energy Engineering Michael Snyder revealed that production of a new residential solar panel has started at Tesla’s Buffalo, New York facility, with shipments to customers beginning in the first quarter of 2026.
The comments hint at possible renewed life for the Solar Roof program, which has seen years of slow growth since its 2016 unveiling.
Tesla Energy’s strong demand
Responding to an investor question about Tesla’s energy backlog, Snyder said demand for Megapack and Powerwall continues to be “really strong” into next year. He also noted positive customer feedback for the company’s new Megablock product, which is expected to start shipping from Houston in 2026.
“We’re seeing remarkable growth in the demand for AI and data center applications as hyperscalers and utilities have seen the versatility of the Megapack product. It increases reliability and relieves grid constraints,” he said.
Snyder also highlighted a “surge in residential solar demand in the US,” attributing the spike to recent policy changes that incentivize home installations. Tesla expects this trend to continue into 2026, helped by the rollout of a new solar lease product that makes adoption more affordable for homeowners.
Possible Solar Roof revival?
Perhaps the most intriguing part of Snyder’s remarks, however, was Tesla’s move to begin production of its “residential solar panel” in Buffalo, New York. He described the new panels as having “industry-leading aesthetics” and shape performance, language Tesla has used to market its Solar Roof tiles in the past.
“We also began production of our Tesla residential solar panel in our Buffalo factory, and we will be shipping that to customers starting Q1. The panel has industry-leading aesthetics and shape performance and demonstrates our continued commitment to US manufacturing,” Snyder said during the Q3 2025 earnings call.
Snyder did not explicitly name the product, though his reference to aesthetics has fueled speculation that Tesla may finally be preparing a large-scale and serious rollout of its Solar Roof line.
Originally unveiled in 2016, the Solar Roof was intended to transform rooftops into clean energy generators without compromising on design. However, despite early enthusiasm, production and installation volumes have remained limited for years. In 2023, a report from Wood Mackenzie claimed that there were only 3,000 operational Solar Roof installations across the United States at the time, far below forecasts. In response, the official Tesla Energy account on X stated that the report was “incorrect by a large margin.”
