Tesla battery partner Panasonic debunks rumors about alleged Gigafactory 1 conflicts
Panasonic Corporation President Kazuhiro Tsuga effectively debunked speculations alleging that the Japanese company’s relationship with American electric car maker Tesla is on the rocks. During a recent Q&A session, Tsuga explained the dynamic between Tesla and Panasonic, as well as his insights about the idea of the electric car maker utilizing another battery supplier for Gigafactory 3.
The relationship between Tesla and Panasonic was thrown into question following a report from the Nikkei Asian Review last month, which alleged that the Japanese company was freezing its investments in Gigafactory 1. Tesla responded to the report, stating that there is far more output to be gained by improving the existing production lines in the Nevada-based factory. Elon Musk took to Twitter as well, stating that Panasonic’s lines at Gigafactory 1 are only operating at ~24 GWh per year despite having a theoretical capacity of 35 GWh.
Musk’s tweets were promptly interpreted as a “public battle” with Panasonic. Craig Irwin of Roth Capital Partners noted that “Tesla and Panasonic need couples counseling ASAP,” adding that “this is looking like a much more acrimonious relationship.” Tsuga, for his part, mentioned that Tesla and Panasonic maintain a “very good relationship between ourselves” during the Q&A session. Explaining further, the Panasonic President pointed out that the two companies have always been candid with each other, especially when it comes to investments in facilities such as Gigafactory 1.
“(In) the earlier session with the media, there was a question as to (whether) we have (a) bad relationship, (or if) we’re not getting along with Tesla. Well, we are making sure that we have a partnership relationship, not a supplier relationship. And since we are partners, we are very frank and candid and honest to each other. So on this battery business, as for the investment facilities — for the facilities that we have invested, can we maintain the battery operation with the orders coming in? From Tesla’s point of view, with the batteries being supplied, they can manufacture their vehicles on a full capacity basis.
“Unless that is established, this would not be a win-win relationship. In the past, what hurt us (was) that we were told that ‘This is the capacity you’ll need,’ but we couldn’t sell that much batteries. That’s the worst case. And that sense, Tesla is purchasing everything that we manufacture. And they have not just the electric vehicles but they do have the storage batteries as well, and they are asking for the capacity increase all the time. And therefore, we have capacity but not being produced. That situation is not envisioned for Gigafactory for now. So I think we have a very good relationship between ourselves,” Tsuga said.
Other concerns that were brought forward on the heels of the Nikkei report were Panasonic’s speculated issues about Tesla’s potential local battery partner in Gigafactory 3. Tesla is speculated to utilize a local battery supplier for the Shanghai-based electric car production facility, a strategy that analysts such as Cairn Energy Research Advisors managing director Sam Jaffe believed would irk Panasonic. “Tesla is starting to flirt with other battery makers in China, and Panasonic doesn’t like that,” Jaffe said in a statement to the Los Angeles Times.
Panasonic President Tsuga expressed a completely different sentiment about the topic, noting that it makes sense for Tesla to adopt a multiple supplier model for Gigafactory 3. “Now because of what happens in China, Tesla is considering a multiple supplier structure, which makes sense for Tesla maybe given the very special nature of doing business in China, and maybe they need to have that structure so as to be approved by China authority. So on the part of Tesla, they might prefer — they might start considering getting multiple suppliers, but that doesn’t mean that our relationship is being hurt and is being unstable, no. We continue to have very solid, very strong relationship with Tesla,” Tsuga said.
Panasonic and Tesla have been in a close working relationship for years. The Japanese company currently produces the battery cells for Tesla’s vehicles, from the 18650 cells used in the Model S and Model X to the 2170 cells utilized in the Model 3. Considering the recent statements of the Panasonic President, as well as Tesla’s ramp of its existing and upcoming products, it appears that the two companies’ partnership will likely remain strong for some time to come.

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.

Tesla Powerwall distribution expands in Australia
Inventory is expected to arrive in late February and official sales are expected to start mid-March 2026.
Supply Partners Group has secured a distribution agreement for the Tesla Powerwall in Australia, with inventory expected to arrive in late February and official sales beginning in mid-March 2026.
Under the new agreement, Supply Partners will distribute Tesla Powerwall units and related accessories across its national footprint, as noted in an ecogeneration report. The company said the addition strengthens its position as a distributor focused on premium, established brands.
“We are proud to officially welcome Tesla Powerwall into the Supply Partners portfolio,” Lliam Ricketts, Co-Founder and Director of Innovation at Supply Partners Group, stated.
“Tesla sets a high bar, and we’ve worked hard to earn the opportunity to represent a brand that customers actively ask for. This partnership reflects the strength of our logistics, technical services and customer experience, and it’s a win for installers who want premium options they can trust.”
Supply Partners noted that initial Tesla Powerwall stock will be warehoused locally before full commercial rollout in March. The distributor stated that the timing aligns with renewed growth momentum for the Powerwall, supported by competitive installer pricing, consumer rebates, and continued product and software updates.
“Powerwall is already a category-defining product, and what’s ahead makes it even more compelling,” Ricketts stated. “As pricing sharpens and capability expands, we see a clear runway for installers to confidently spec Powerwall for premium residential installs, backed by Supply Partners’ national distribution footprint and service model.”
Supply Partners noted that a joint go-to-market launch is planned, including Tesla-led training for its sales and technical teams to support installers during the home battery system’s domestic rollout.

Tesla Megapack Megafactory in Texas advances with major property sale
Stream Realty Partners announced the sale of Buildings 9 and 10 at the Empire West industrial park, which total 1,655,523 square feet.
Tesla’s planned Megapack factory in Brookshire, Texas has taken a significant step forward, as two massive industrial buildings fully leased to the company were sold to an institutional investor.
In a press release, Stream Realty Partners announced the sale of Buildings 9 and 10 at the Empire West industrial park, which total 1,655,523 square feet. The properties are 100% leased to Tesla under a long-term agreement and were acquired by BGO on behalf of an institutional investor.
The two facilities, located at 100 Empire Boulevard in Brookshire, Texas, will serve as Tesla’s new Megafactory dedicated to manufacturing Megapack battery systems.
According to local filings previously reported, Tesla plans to invest nearly $200 million into the site. The investment includes approximately $44 million in facility upgrades such as electrical, utility, and HVAC improvements, along with roughly $150 million in manufacturing equipment.
Building 9, spanning roughly 1 million square feet, will function as the primary manufacturing floor where Megapacks are assembled. Building 10, covering approximately 600,000 square feet, will be dedicated to warehousing and logistics operations, supporting storage and distribution of completed battery systems.
Waller County Commissioners have approved a 10-year tax abatement agreement with Tesla, offering up to a 60% property-tax reduction if the company meets hiring and investment targets. Tesla has committed to employing at least 375 people by the end of 2026, increasing to 1,500 by the end of 2028, as noted in an Austin County News Online report.
The Brookshire Megafactory will complement Tesla’s Lathrop Megafactory in California and expand U.S. production capacity for the utility-scale energy storage unit. Megapacks are designed to support grid stabilization and renewable-energy integration, a segment that has become one of Tesla’s fastest-growing businesses.
