A Tesla Megapack-based battery energy storage system (BESS) has gone live in Scotland, in partnership with TagEnergy and Harmony Energy.
As detailed in a press release from TagEnergy on Tuesday, the Jamesfield Megapack project outside of Abernathy, Scotland is now fully operational, offering 49MW of power and 98MWh of energy storage. TagEnergy also says that sections of the project began powering on in November 2023, as the system was progressively brought online.

“Battery energy storage systems are vital for unlocking the full potential of renewable energy in the UK,” said Peter Kavanagh, Harmony Energy CEO. “They play a pivotal role in advancing the Net Zero transition through the reduction of Co2 emissions, and are crucial for securing the future stability of the UK’s energy supply and reducing dependence on foreign gas imports.”
The site features 13 of Tesla’s 2-hour duration Megapacks, utilizing the company’s Autobidder AI for optimizing electricity prices with real-time trading. This is also just the latest of the United Kingdom’s BESS projects to go live in the past few years, following those in Chapel Farm in Luton, England, and Hawkers Hill Energy Park in Shaftesbury in Dorset, England.
The release also adds that Harmony Energy now has an operational portfolio of more than 500MW/1GWh, following the launch of the Jamesfield site.
“We love working with trusted, expert partners who share our passion for a renewables-led energy future,” wrote TagEnergy in a post on LinkedIn. “This is our second JV with Harmony (after Chapel Farm.) And we’re proud to partner again with Tesla (batteries and software) and RES (asset manager) at Jamesfield too.”
Rohan Patel, Tesla Vice President of Public Policy and Business Development, also responded to the news in a post on X:
“I have to admit my skepticism years ago when Elon Musk said that the Tesla Energy business might eventually be bigger than the Tesla vehicle business,” Patel wrote on Tuesday. “As battery costs come down and electricity system operators understand the grid benefits (distribution and transmission), there seems to be no end in sight to the growth trajectory globally.
“Countries and regions with fair market participation rules for storage will end up as the ‘winners’, with more efficient and cheaper electricity grids for all consumers.”
Tesla has continued to ramp up Megapack production at its facility in Lathrop, California, and it’s set to break ground on a new Megafactory in Shanghai, China sometime this year. Both facilities are expected to eventually reach an annual production capacity of about 10,000 Megapacks.

Tesla reveals its first Semi customer after launch
Tesla revealed its first customer for the all-electric Semi truck after it launches next year. Who it truly is should not be a surprise.
The Semi is going to finally start deliveries to new companies outside of Tesla’s pilot program starting in 2026. The company has been building a dedicated production facility in Reno, Nevada, that has finally taken shape, but Tesla was evidently not finished with the Semi’s development.
Last week at the Annual Shareholder Meeting, Tesla said it had implemented some new designs into the Semi, helping with efficiency, updating its design, and making it a more suitable vehicle for hauling loads, as the changes also helped increase payload.
Tesla has obtained a lengthy list of companies that have committed to implementing the Semi in their own fleets, hoping to bring their logistics lineups up to date with electric powertrains and autonomous technologies.
While it is already operating a pilot program with PepsiCo. and Frito-Lay, Tesla will expand to other businesses, primarily using it internally after its launch.
Head of the Semi program at Tesla, Dan Priestley, said the company would be the first user of the vehicle after its launch next year. It has been using it to a certain extent, but the company has not been able to completely abandon gas haulers.
Instead, it will implement the Semi into its fleet for more sustainable vehicle logistics starting next year:
Tesla will be the first customer as we electrify our supply chain. This includes Texas operations.

Tesla has already received orders for the Semi from a variety of large companies, including Walmart, Sysco, Anheuser-Busch, UPS, DHL, J.B. Hunt, among others.
Many analysts see the Tesla Semi as a major contributor to future growth and increasing value within the company, especially from a Wall Street perspective. Some firms say the Semi is one of several near and medium-term contributors to the company increasing its market cap.
Cantor Fitzgerald is just one of those firms, as last week it explicitly listed the Semi as a catalyst.
Analyst Andres Sheppard said, “Overall, we remain bullish on TSLA over the medium to long term. We continue to see meaningful future upside from Energy Storage & Deployment, FSD, Robotaxis/Cybercab, Semis, and Optimus Bots.”

Tesla China rolls out Model Y L V2L adapter, and it’s free for early owners
Tesla China announced the rollout of the Model Y L’s AC external power adapter on social media platforms such as Weibo.
Tesla China has released a useful new accessory for the Model Y L, and it is free for some owners. With the accessory, the Model Y L effectively becomes a giant power bank that owners can use to power appliances when they are camping, or if their homes are hit by a power outage.
Tesla Model Y L V2L adapter
Tesla China announced the rollout of the Model Y L’s AC external power adapter on social media platforms such as Weibo. As per the product’s advertisement, the Model Y L could provide up to 2,200W of power with its adapter, allowing it to support numerous appliances on the go. Of course, but could also be used to charge devices during power outages.
Tesla China notes that the adapter’s current is 220V, and it also features an IP44 protection grade. Tesla notes that the adapter could operate at temperatures between -30℃ ~ +50℃. The Model Y L’s V2L functionality would not work if the vehicle’s battery is less than 10%, however.
Tesla China’s official shop is selling its AC external power adapter for a reasonable price. The product could be purchased for RMB599, which is equivalent to $85. That’s a great price for an accessory that could make car camping sessions several times more convenient.
Free for early Model Y L owners
While the Model Y L’s AC external power adapter is priced reasonably at the Tesla China shop, the accessory is available for free for early owners of the extended wheelbase six-seat all-electric crossover. This was highlighted in a message that Tesla China reportedly sent to owners of the vehicle.
“Your Tesla account is eligible for a free Model Y L dedicated AC external power adapter. Please log in to the online store to add the adapter to your cart. Once the system verifies it correctly, the price will automatically change to 0 yuan before placing the order. We will send it to you via express delivery subsequently.
“This free qualification is only for the first owner of the Model YL who did not receive an AC external power adapter at pickup, valid until February 28, 2026. Failure to place an order upon expiration will be considered as a waiver of eligibility. If there is a temporary shortage of goods, please be patient and we will reschedule the replenishment by the end of January 2026,” Tesla China wrote.

Tesla Cybertruck and Model 3 program manager steps down
The now-former executive played a central role in several of Tesla’s key milestones.
Siddhant Awasthi, Tesla’s Program Manager for the Cybertruck and Model 3, has announced his departure after eight years with the company. Starting as an intern, Awasthi played a central role in several of Tesla’s key milestones, from the ramp-up of the Model 3 and Giga Shanghai to the launch of the long-awaited Cybertruck.
From intern to program leader
In a social media post, Awasthi described leaving Tesla as “one of the hardest decisions” of his life. He credited CEO Elon Musk, Tesla’s leadership team, and his colleagues for helping turn ambitious ideas into tangible vehicles. During his tenure, Awasthi contributed to Tesla’s global expansion and the evolution of its vehicle electronics and wireless systems, culminating in the Cybertruck’s long-anticipated rollout in late 2023.
He noted the intensity and innovation of his Tesla years, calling the experience “a thrilling journey” that shaped his career before the age of 30. “It’s been an absolute privilege,” he wrote, adding that working with “rockstar colleagues” made even the most demanding days worthwhile.
Tesla’s leadership transitions
Awasthi’s departure comes as Tesla continues to scale global operations and prepare for major product updates, including next-gen vehicle platforms and software-driven improvements. Despite stepping away, Awasthi voiced confidence in Tesla’s future. “I’m confident Tesla will nail its next big mission,” he said, highlighting his belief in the company’s capacity to deliver breakthrough products and improve safety for drivers worldwide.
“This decision wasn’t easy, especially with so much exciting growth on the horizon. Tesla vehicles are incredibly complex systems that often don’t get the credit they deserve, but I’ve witnessed firsthand how they’ve changed lives—for our customers, my friends, and my family—adding real value and, above all, improving safety. I’m confident Tesla will nail its next big mission (especially after last week), and I’m truly excited for the next chapter of my life,” the former Tesla executive wrote.
