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 Board Chair Robyn Denholm has provided a rather compelling update on Optimus’ improving dexterity. As per the executive, the humanoid robot, which is expected to enter initial production next year, is now able to perform more deliberate tasks, such as folding laundry. 

Optimus’ dexterity

During an interview with CNBC, Denholm was asked how close Optimus was to true dexterity. Achieving human-like dexterity is a key goal for Optimus as the robot is designed to be able to perform tasks that are traditionally performed by humans. This means that Optimus should be able to move its hands in a very delicate manner. During the segment, one of CNBC’s hosts mentioned that humanoid robots today are not able to fold laundry just yet. 

Denholm responded that Tesla’s robot is now able to perform the task. “Optimus can fold laundry. I’ve been in the lab with Optimus. He can fold laundry. He can wipe the table really well. He can hand things to you. You can actually shake hands with him. The tactile nature of his hand is actually really very good,” the Tesla Board Chair stated.

Redefining robotics

The executive reiterated that Optimus is already operating in Tesla’s Palo Alto offices today. “We’re redefining what transportation is, but we’re also redefining robotics and what AI brings to robotics and how versatile the robots will be in the future,” Denholm noted.

Elon Musk has reiterated the importance of Optima’s hands during the Q3 2025 earnings call. While discussing the humanoid robot’s capabilities, Musk stated that Optimus, in its production form in the future, should be able to perform incredibly delicate tasks such as surgery. This, the CEO noted, would be pivotal in Tesla’s efforts to push the world towards sustainable abundance.

“Going beyond sustainable energy to say, sustainable abundance is the mission, where we believe with Optimus and self-driving, we can actually create a world where there is no poverty, where everyone has access to the finest medical care. Optimus will be an incredible surgeon, for example. Imagine if everyone had access to an incredible surgeon,” Musk said.

Tesla comes through on huge promise for Bay Area ride-hailing service

Tesla’s ride-hailing service in the California Bay Area is somewhat similar to what the company is doing with Robotaxi in Austin, Texas.

Tesla has come through on a huge promise for its Bay Area ride-hailing service just two months after aiming to expand to a new territory.

Tesla’s ride-hailing service in the California Bay Area is somewhat similar to what the company is doing with Robotaxi in Austin, Texas.

However, regulatory rules and the fact that the company is operating with someone in the driver’s seat —a stark difference from the operation in Austin —have kept the business categorized as a ride-hailing application in California.

But Tesla is still breaking barriers down with its service, which operates entirely using the Full Self-Driving (Supervised) platform, as the “Safety Monitors” are only there to ensure safety and take over in the most necessary circumstances.

In September, Tesla filed to begin operating its ride-hailing service at various airports in the Bay Area, including San Francisco International Airport, San Jose Mineta International Airport, and Oakland International Airport.

Tesla targets Bay Area airports as next step for Robotaxi rollout

It officially came through on that promise last night, as it announced its Bay Area ride-hailing service would now go to San Jose Mineta International Airport:

The expansion signals a key approval for Tesla to travel to one of the more popular places where people would need or simply want a drop-off. Airports are expensive to park in, so many people utilize ride-hailing services to enable a more economical experience from start to finish.

With this approval for SJC, Tesla will likely gain even more approvals for other airports in the Bay Area in the coming weeks or months.

While Tesla believes at least half of the U.S. population will have access to the company’s Robotaxi program or its ride-hailing service by the end of the year, the first step will be gaining approval in more metropolitan areas.

Tesla is looking to expand to other states, including Nevada, Florida, and Arizona, with its Robotaxi platform in the near future.

Tesla warns Elon Musk could step down if shareholders reject pay plan

Denholm’s letter emphasized Tesla is at a “critical inflection point” as it scales AI-driven projects such as Full Self-Driving (FSD) and Optimus.

Tesla Board Chair Robyn Denholm has urged shareholders to approve CEO Elon Musk’s new 2025 Performance Award ahead of the November 6 Annual Meeting, warning that rejecting it could risk losing his leadership. 

In a letter posted on Tesla’s official handle on X, Denholm stated that the company must “foster an environment that motivates Elon to achieve great things,” or risk losing “his time, talent, and vision,” which she described as essential to Tesla’s success.

Retaining Musk amid Tesla’s critical transition

Denholm’s letter emphasized Tesla is at a “critical inflection point” as it scales AI-driven projects such as Full Self-Driving (FSD) and Optimus. She argued that Musk’s leadership remains vital as Tesla pushes toward becoming “the leading provider of autonomous solutions and the most valuable company in the world.” Without a new performance-based plan, Denholm warned, Musk could step away, potentially costing Tesla significant long-term value.

“If we fail to foster an environment that motivates Elon to achieve great things through an equitable pay-for-performance plan, we run the risk that he gives up his executive position, and Tesla may lose his time, talent, and vision, which have been essential to delivering extraordinary shareholder returns,” the Tesla Board Chair stated.

The board’s proposed 2025 Performance Award aligns Musk’s compensation with ambitious targets while extending his commitment for at least 7.5 more years. Denholm stated that the vote is a defining moment for Tesla’s future direction, adding that the plan was designed to keep Musk focused on innovation while maintaining governance discipline. “A vote here is both an endorsement of Elon’s vision and a vote for Tesla’s carefully tailored strategy,” she said.

Musk’s pay history is rooted in performance

Elon Musk’s pay history with Tesla has long been unconventional. For years, he has declined a regular salary, instead directly tying his earnings to Tesla’s ability to meet ambitious production and market-value goals. His 2018 performance award, approved by shareholders at a time when Tesla had a market cap of just about $59 billion, granted him stock options only when Tesla reached aggressive growth milestones, such as growing the company’s market cap to $650 billion. 

At the time, the milestones included $50 billion additions to Tesla’s market cap, which were considered by many to be unrealistic. Those goals were ultimately met by the electric vehicle maker, but a Delaware court later rescinded the plan in January 2024, calling it an “unfathomable sum.”

Tesla shareholders reaffirmed support for Musk’s pay in 2024, even as legal disputes continued. The board then issued an interim equity package valued around $29 billion while developing a new long-term plan earlier this year. Since then, Tesla’s Board has proposed Musk’s 2025 CEO Performance Award, which could be worth nearly $1 trillion, but only if Musk were to grow Tesla into the world’s most valuable company with a market cap of $8.5 trillion, among other aggressive and ambitious targets.
