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 CEO Elon Musk sends final warning to Bill Gates over short position
“If Gates hasn’t fully closed out the crazy short position he has held against Tesla for ~8 years, he had better do so soon,” Musk said.
Tesla CEO Elon Musk sent a final warning to former Microsoft CEO Bill Gates over his short position, which he confirmed he held to Musk directly several years ago.
Gates has been a skeptic of Tesla for some time, but he has also tried to work with Musk on philanthropic opportunities several years ago, which was coincidentally when he admitted to the company’s frontman that he held a short position.
Musk was, in turn, “super mean” to Gates, according to Walter Isaacson’s biography about the Tesla CEO. Gates had put $500 million against Tesla, shorting the stock and hoping to profit from its failure.
Elon Musk explains Bill Gates beef: He ‘placed a massive bet on Tesla dying’
A short position essentially means Gates is betting Tesla shares will go down, which would make him money. However, shares have gone up over six percent this year and increased nearly 150 percent over the past five years.
At the recent Annual Shareholder Meeting, Musk made many claims about Tesla’s future projects and how they could manage to disrupt various industries. He also recently had a massive $1 trillion compensation package approved, which will be awarded in twelve tranches, all of which combine a company valuation goal and an individual goal related to a product.
Musk was able to complete his last approved pay package, but it was not awarded due to a ruling by a Delaware Chancery Court. Nevertheless, his track record of proving growth for Tesla shareholders is excellent, and investors are obviously very encouraged by his capabilities as a CEO, considering 76.6 percent of shareholders voted to approve his new compensation.
After it was revealed that the Gates Foundation dumped 65 percent of its Microsoft position for nearly $9 billion, Musk had one final message for him: drop your Tesla short position soon, or else.
If Gates hasn’t fully closed out the crazy short position he has held against Tesla for ~8 years, he had better do so soon
— Elon Musk (@elonmusk) November 16, 2025
Musk’s rivalry with Gates is mostly founded on the Tesla CEO’s discontent with the former Microsoft frontman’s short position. However, Musk might have a bit of a soft spot for Gates, considering he is giving him a warning of what is potentially to come. If he really wanted to do some damage to Gates, he would not give him any heads-up at all.

Tesla rolls out most aggressive Model Y lease deal in the US yet
With the promotion in place, customers would be able to take home a Model Y at a very low cost.
Tesla has rolled out what could very well be its most aggressive promotion for Model Y leases in the United States yet. With the promotion in place, customers would be able to take home a Model Y at a very low cost.
Zero downpayment leases
The new Model Y lease promotion was initially reported on X, with industry watcher Sawyer Merritt stating that while the vehicles’ monthly payments are still similar to before, the cars can now be ordered with a $0 downpayment.
Tesla community members noted that this promotion would cut the full payment cost of Model Y leases by several thousand dollars, though prices were still a bit better when the $7,500 federal tax credit was still in effect. Despite this, a $0 downpayment would likely be appreciated by customers, as it lowers the entry point to the Tesla ecosystem by a notable margin.
Premium freebies included
Apart from a $0 downpayment, customers of Model Y leases are also provided one free upgrade for their vehicles. These upgrades could be premium paint, such as Pearl White Multi-Coat, Deep Blue Metallic, Diamond Black, Quicksilver or Ultra Red, or 20″ Helix 2.0 Wheels. Customers could also opt for a White Interior or a Tow Hitch free of charge.
A look at Tesla’s Model Y order page shows that the promotion is available for all the Model Y Premium Rear-Wheel Drive and the Model Y Premium All-Wheel Drive. The Model Y Standard and the Model Y Performance are not eligible for the $0 downpayment or free premium upgrade promotion as of writing.

Tesla is looking to phase out China-made parts at US factories: report
Tesla has reportedly swapped out several China-made components already, aiming to complete the transition within the next two years.
Tesla has reportedly started directing its suppliers to eliminate China-made components from vehicles built in the United States. This would make Tesla’s US-produced vehicles even more American-made.
The update was initially reported by The Wall Street Journal.
Accelerating North American sourcing
As per the WSJ report, the shift reportedly came amidst escalating tariff uncertainties between Washington and Beijing. Citing people reportedly familiar with the matter, the publication claimed that Tesla has already swapped out several China-made components, aiming to complete the transition within the next two years. The publication also claimed that Tesla has been reducing its reliance on China-based suppliers since the pandemic disrupted supply chains.
The company has quietly increased North American sourcing over the past two years as tariff concerns have intensified. If accurate, Tesla would likely end up with vehicles that are even more locally sourced than they are today. It would remain to be seen, however, if a change in suppliers for its US-made vehicles would result in price adjustments for cars like the Model 3 and Model Y.
Industry-wide reassessments
Tesla is not alone in reevaluating its dependence on China. Auto executives across the automotive industry have been in rapid-response mode amid shifting trade policies, chip supply anxiety, and concerns over rare-earth materials. Fluctuating tariffs between the United States and China during President Donald Trump’s current term have made pricing strategies quite unpredictable as well, as noted in a Reuters report.
General Motors this week issued a similar directive to thousands of suppliers, instructing them to remove China-origin components from their supply chains. The same is true for Stellantis, which also announced earlier this year that it was implementing several strategies to avoid tariffs that were placed by the Trump administration.
