Details of Tesla’s Megapack installation at Gigafactory Texas have been revealed in documents related to the plant. Among these is a filing receipt about the installation, which included sections on the number of Megapack batteries that will be used, as well as the system’s capacity.
Longtime Tesla Giga Texas watcher Joe Tegtmeyer shared a copy of the document from the Lower Colorado River Authority (LCRA). The Tesla enthusiast, who has been taking drone videos of Tesla’s Texas sites for some time now, has also been following the progress of the buildout of the Gigafactory’s battery storage system for the past months.
As noted in the Texas LCRA document, the battery installation will be comprised of 68 Megapack battery units that are rated at approximately 2 MW each. The delivery voltage of the system is listed as 345 kV in the document. Other key details about the upcoming battery installation were also listed in the document.
“The Plant is a Battery Energy Storage System (“BESS”) facility with one Point of Interconnection to the grid. The Plant nameplate rating will be approximately 163.2-MVA of AC power (with a maximum real power rating of 131.05-MW) at the inverter 480VAC terminals (low voltage),” the document read.

A look at the Tesla Megapack order page shows that 1.9 MW of power and 3.9 MWh of energy is possible with the battery’s 2-hour duration. Shifting to a 4-hour Megapack duration shifts the battery’s power to 1 MW. Considering the contents of the LCRA document, it would appear that Tesla will be using the battery’s 2-hour setup for Giga Texas’ battery storage system.
Adjusting the quantity of the Megapack in the battery’s order page to 68 units shows that the power of the system would be 131 MW, and its energy would be at 262.1 MWh. This would make the installation larger than the Hornsdale Power Reserve, one of Tesla’s most famous battery installations that was once considered the largest in the world. For context, the Hornsdale battery, which was composed of Tesla Powerpack units, featured 100 MW of power and 129 MWh of energy when it was installed in 2017.

Tesla director pay lawsuit sees lawyer fees slashed by $100 million
The ruling leaves the case’s underlying settlement intact while significantly reducing what the plaintiffs’ attorneys will receive.
The Delaware Supreme Court has cut more than $100 million from a legal fee award tied to a shareholder lawsuit challenging compensation paid to Tesla directors between 2017 and 2020.
The ruling leaves the case’s underlying settlement intact while significantly reducing what the plaintiffs’ attorneys will receive.
Delaware Supreme Court trims legal fees
As noted in a Bloomberg Law report, the case targeted pay granted to Tesla directors, including CEO Elon Musk, Oracle founder Larry Ellison, Kimbal Musk, and Rupert Murdoch. The Delaware Chancery Court had awarded $176 million to the plaintiffs. Tesla’s board must also return stock options and forego years worth of pay.
As per Chief Justice Collins J. Seitz Jr. in an opinion for the Delaware Supreme Court’s full five-member panel, however, the decision of the Delaware Chancery Court to award $176 million to a pension fund’s law firm “erred by including in its financial benefit analysis the intrinsic value” of options being returned by Tesla’s board.
The justices then reduced the fee award from $176 million to $70.9 million. “As we measure it, $71 million reflects a reasonable fee for counsel’s efforts and does not result in a windfall,” Chief Justice Seitz wrote.
Other settlement terms still intact
The Supreme Court upheld the settlement itself, which requires Tesla’s board to return stock and options valued at up to $735 million and to forgo three years of additional compensation worth about $184 million.
Tesla argued during oral arguments that a fee award closer to $70 million would be appropriate. Interestingly enough, back in October, Justice Karen L. Valihura noted that the $176 award was $60 million more than the Delaware judiciary’s budget from the previous year. This was quite interesting as the case was “settled midstream.”
The lawsuit was brought by a pension fund on behalf of Tesla shareholders and focused exclusively on director pay during the 2017–2020 period. The case is separate from other high-profile compensation disputes involving Elon Musk.

SpaceX-xAI merger discussions in advanced stage: report
The update was initially reported by Bloomberg News, which cited people reportedly familiar with the matter.
SpaceX is reportedly in advanced discussions to merge with artificial intelligence startup xAI. The talks could reportedly result in an agreement as soon as this week, though discussions remain ongoing.
The update was initially reported by Bloomberg News, which cited people reportedly familiar with the matter.
SpaceX and xAI advanced merger talks
SpaceX and xAI have reportedly informed some investors about plans to potentially combine the two privately held companies, Bloomberg’s sources claimed. Representatives for both companies did not immediately respond to requests for comment.
A merger would unite two of the world’s largest private firms. xAI raised capital at a valuation of about $200 billion in September, while SpaceX was preparing a share sale late last year that valued the rocket company at roughly $800 billion.
If completed, the merger would bring together SpaceX’s launch and satellite infrastructure with xAI’s computing and model development. This could pave the way for Musk’s vision of deploying data centers in orbit to support large-scale AI workloads.
Musk’s broader consolidation efforts
Elon Musk has increasingly linked his companies around autonomy, AI, and space-based infrastructure. SpaceX is seeking regulatory approval to launch up to one million satellites as part of its long-term plans, as per a recent filing. Such a scale could support space-based computing concepts.
SpaceX has also discussed the feasibility of a potential tie-up with electric vehicle maker Tesla, Bloomberg previously reported. SpaceX has reportedly been preparing for a possible initial public offering (IPO) as well, which could value the company at up to $1.5 trillion. No timeline for SpaceX’s reported IPO plans have been announced yet, however.

Tesla already has a complete Robotaxi model, and it doesn’t depend on passenger count
That scenario was discussed during the company’s Q4 and FY 2025 earnings call, when executives explained why the majority of Robotaxi rides will only involve one or two people.
Tesla already has the pieces in place for a full Robotaxi service that works regardless of passenger count, even if the backbone of the program is a small autonomous two-seater.
That scenario was discussed during the company’s Q4 and FY 2025 earnings call, when executives explained why the majority of Robotaxi rides will only involve one or two people.
Two-seat Cybercabs make perfect sense
During the Q&A portion of the call, Tesla Vice President of Vehicle Engineering Lars Moravy pointed out that more than 90% of vehicle miles traveled today involve two or fewer passengers. This, the executive noted, directly informed the design of the Cybercab.
“Autonomy and Cybercab are going to change the global market size and mix quite significantly. I think that’s quite obvious. General transportation is going to be better served by autonomy as it will be safer and cheaper. Over 90% of vehicle miles traveled are with two or fewer passengers now. This is why we designed Cybercab that way,” Moravy said.
Elon Musk expanded on the point, emphasizing that there is no fallback for Tesla’s bet on the Cybercab’s autonomous design. He reiterated that the autonomous two seater’s production is expected to start in April and noted that, over time, Tesla expects to produce far more Cybercabs than all of its other vehicles combined.
“Just to add to what Lars said there. The point that Lars made, which is that 90% of miles driven are with one or two passengers or one or two occupants, essentially, is a very important one… So this is clearly, there’s no fallback mechanism here. It’s like this car either drives itself or it does not drive… We would expect over time to make far more CyberCabs than all of our other vehicles combined. Given that 90% of distance driven or distance being distance traveled exactly, no longer driving, is one or two people,” Musk said.
Tesla’s robotaxi lineup is already here
The more interesting takeaway from the Q4 and FY 2025 earnings call is the fact that Tesla does not need the Cybercab to serve every possible passenger scenario, simply because the company already has a functional Robotaxi model that scales by vehicle type.
The Cybercab will handle the bulk of the Robotaxi network’s trips, but for groups that need three or four seats, the Model Y fills that role. For higher-end or larger-family use cases, the extended-wheelbase Model Y L could cover five or six occupants, provided that Elon Musk greenlights the vehicle for North America. And for even larger groups or commercial transport, Tesla has already unveiled the Robovan, which could seat over ten people.
Rather than forcing one vehicle to satisfy every use case, Tesla’s approach mirrors how transportation works today. Different vehicles will be used for different needs, while unifying everything under a single autonomous software and fleet platform.
