Tesla is currently ‘aggressively ramping’ energy business, says CTO JB Straubel
Amid rising competition in the residential solar market from rivals such as SunRun, Tesla CTO JB Straubel stated that Tesla is ramping up its efforts to bolster its energy business. According to Straubel, the reception of the public to products like the Powerwall 2 and Solar Roof tiles has been similar to the Model 3. Thus, Tesla is now doing what it can to increase its capacity to produce its energy products as fast as it can.
Straubel’s update to Tesla’s energy business came as a statement to USA Today, which recently published an article about the residential solar market in the United States. While the Tesla CTO did not provide the actual figures of its Powerwall 2 and Solar Roof reservations, Straubel did state that for now, Tesla is unable to keep up with deposits being put down for the products. Straubel also emphasized that Tesla is not in any way stepping back from the residential energy business.
“No one should see us as stepping back from solar. In fact, it’s the opposite. It’s like with Model 3. People have come flooding in and are waiting on the product. So now we’re aggressively ramping our capacity,” he said.
To address the demand for its residential products, Straubel stated that production of the Powerwall 2 is set to pick up later this year, while output for Solar Roof tiles is expected to accelerate in 2019. The Tesla CTO expects these initiatives to reduce the wait times for these energy products.
The Tesla CTO’s latest statement comes as an encouraging update to the company’s residential energy business, much of which has been under the news radar for most of the year. The first consumer installations of the Solar Roof began earlier this year, and reports emerged that Gigafactory 2 in Buffalo, NY is ramping up hiring, but apart from these, Tesla’s energy initiatives appear to be focused on large-scale industrial projects, such as its upcoming Powerpack farm in Victoria, and its virtual power plant in South Australia.
Tesla’s residential energy business in the United States took a blow last month, as well, with the company closing a dozen of its solar facilities across nine states in the country as part of its restructuring. Apart from this, Tesla also announced that it would not renew its partnership with Home Depot to sell its solar solutions and Powerwall 2 home battery storage units.
Regardless of these, the progress of Tesla’s industrial energy projects is indicative of the potential of its residential initiatives. Over the past year, after all, Tesla had all but proved that its battery technology is a feasible alternative to conventional power solutions. The warm reception to its big battery in South Australia, which continues to support the region’s embattled energy grid, is a testament to this.
Considering the competition from its local competitors, Tesla would have to increase its push for its residential energy business in the United States. Solar analyst for GTM Research Allison Mond, for one, stated that Tesla could see its market share shrink in the coming quarters due to competitors and the company’s lack of focus on its solar products. Nevertheless, Straubel stated that market share is not really Tesla’s focus for its residential energy business.
“We’re focused intently on the customer experience, not on having a higher market share. We’re looking at the bigger picture,” he said.
During Tesla’s 2018 Annual Shareholder Meeting, Tesla CEO Elon Musk mentioned that the company is getting closer to a battery breakthrough. Addressing shareholders, Musk stated that Tesla is on pace to hit a battery cell cost of $100 per kWh by the end of 2018 depending on the stability of current commodity prices. Considering Straubel’s mention of a ramp in Powerwall 2 production later this year, it seems like Tesla’s push into residential solar could happen just as the company hits a breakthrough in its battery technology.

Tesla named by U.S. Gov. in $4.3B battery deal for American-made cells
What began as an open secret in the energy industry was confirmed by the U.S. Department of the Interior on Monday: Tesla is the buyer behind LG Energy Solution’s blockbuster $4.3 billion battery supply agreement.
What began as an open secret in the energy industry is becoming more real after the U.S. Department of the Interior named Tesla as the stakeholder in the LG Energy Solution’s blockbuster $4.3 billion battery supply agreement.
Tesla and LG Energy Solution are expanding their partnership to build a LFP prismatic battery cell manufacturing facility in Lansing, Michigan, launching production in 2027. The announcement, made as part of the Indo-Pacific Energy Security Summit results, ends months of speculation.
“American-made cells will power Tesla’s Megapack 3 energy storage systems produced in Houston, creating a robust domestic battery supply chain.”, notes a press release on the U.S. Department of the Interior website.
Tesla has long utilized China’s Contemporary Amperex Technology Co. (CATL), the world’s largest LFP battery maker, as one of its primary suppliers. That relationship made financial sense for years, considering that Chinese LFP cells were cheap, abundant, and reliable. But with escalated tariffs on Chinese imports and an increasingly growing Tesla Energy business that’s particularly reliant on LFP cells for products including its Megapack battery storage units designed for utilities and large-scale commercial projects.
The announcement of a deepened partnership between LG Energy Solution and Tesla has strategic logic for both parties. For Tesla, it secures a tariff-compliant, domestically produced battery supply for its fast-growing energy division. LGES, now producing LFP batteries in Michigan, becomes the only major supplier currently scaling U.S. production, outpacing rivals like Samsung SDI and SK On. LG Energy Solution’s Lansing plant, formerly known as Ultium Cells 3, was previously operated as a joint venture with General Motors. LGES acquired GM’s stake in May 2025 and now fully owns the site, with a production capacity of 50 GWh per year. LG Energy said the contract includes options to extend the supply period by up to seven years and boost volumes based on further consultations.
For the broader industry, the ripple effects are significant. This deal signals that domestic battery manufacturing can be financially viable and not just aspirational. Utilities, energy developers, and rival automakers will take note as American-made LFP supply becomes a competitive reality rather than a distant promise.
For consumers, the benefits will take time but are real. A more resilient, U.S.-based supply chain means fewer price shocks from trade disputes, more stable Megapack availability for the grid storage projects that reduce electricity costs, and long-term downward pressure on energy storage prices as domestic production scales.
Deliveries are set to begin in 2027 and run through mid-2030, and as grid storage demand accelerates, reliable, US-made battery supply is no longer a future ambition. It is becoming a core requirement of the country’s energy strategy.

Tesla Energy gains UK license to sell electricity to homes and businesses
The license was granted to Tesla Energy Ventures Ltd. by UK energy regulator Ofgem after a seven-month review process.
Tesla Energy has received a license to supply electricity in the United Kingdom, opening the door for the company to serve homes and businesses in the country.
The license was granted to Tesla Energy Ventures Ltd. by UK energy regulator Ofgem after a seven-month review process.
According to Ofgem, the license took effect at 6 p.m. local time on Wednesday and applies to Great Britain.
The approval allows Tesla’s energy business to sell electricity directly to customers in the region, as noted in a Bloomberg News report.
Tesla has already expanded similar services in the United States. In Texas, the company offers electricity plans that allow Tesla owners to charge their vehicles at a lower cost while also feeding excess electricity back into the grid.
Tesla already has a sizable presence in the UK market. According to price comparison website U-switch, there are more than 250,000 Tesla electric vehicles in the country and thousands of Tesla home energy storage systems.
Ofgem also noted that Tesla Motors Ltd., a separate entity incorporated in England and Wales, received an electricity generation license in June 2020.
The new UK license arrives as Tesla continues expanding its global energy business.
Last year, Tesla Energy retained the top position in the global battery energy storage system (BESS) integrator market for the second consecutive year. According to Wood Mackenzie’s latest rankings, Tesla held about 15% of global market share in 2024.
The company also maintained a dominant position in North America, where it captured roughly 39% market share in the region.
At the same time, competition in the energy storage sector is increasing. Chinese companies such as Sungrow have been expanding their presence globally, particularly in Europe.
