The Tesla Megapack battery could be considered as one of the rising stars of the company. During the fourth quarter and full year 2023 earnings call, Tesla executives highlighted that the growth of Tesla’s energy storage business would outpace the growth of the company’s automotive division this year. A lot of this growth would be due to the Megapack battery, Tesla’s flagship energy storage product.
The Tesla Megapack battery is the company’s largest energy storage system. Designed for grid-scale projects, the Megapack is offered in two configurations: a 2-hour version offering 1.9 MW of power and 3.9 MWh of energy and a 4-hour variant delivering 1 MW of power and 3.9 MWh of energy. The Megapack has been quite successful so far, with the energy storage device being deployed in high-profile projects such as the 182 MW/730 MWh installation in Moss Landing, California, to the 150 MW/300 MWh system in New South Wales, Australia.
With installation charges, the 2-hour variant is priced at $2,081,060, while the 4-hour variant is priced at $1,865,370. Without installation charges, the 2-hour Megapack is priced at $1,278,860 and the 4-hour variant is priced at $1,227,090. Tesla’s estimated annual maintenance cost for the Megapack battery is $8,830, with the cost rising 2% per year.
The Tesla Megapack is primarily built in the Lathrop Megafactory in California, though another Megafactory is poised to be built in Shanghai this year. And as per a recent drone flyover from Tesla watcher Met God in Wilderness, who has been conducting drone flyovers of some of Tesla’s California facilities, it appears that the Lathrop Megafactory is currently hard at work producing the grid-scale batteries at scale.
At the time of the Tesla watcher’s drone flyover, a total of 326 Tesla Megapacks could be seen on the premises of the Megafactory. That’s quite a lot of Megapacks, with Tesla watchers estimating that the batteries in the facility’s holding lots are likely worth over $500 million. Considering that Megapacks are designed for easy transport and installation, it would not be surprising if many of the batteries that were spotted in the drone operator’s flyover were delivered within the present quarter.
The past year was a period of milestones for Tesla Energy, with deployments seeing a 125% increase compared to 2022. As per Tesla CFO Vaibhav Taneja, the company’s energy storage business is also seeing a rise in revenue. “Our energy storage business had another record year with deployments more than doubling and revenues increasing by more than 50%. This business is poised to again surpass our auto business in terms of growth rate in 2024. This has been in the works for quite some time with us laying the foundation a few years back by building our Mega Factory in Lathrop,” Taneja said during the Q4 and FY 2023 earnings call.

Starlink achieves major milestones in 2025 progress report
Starlink wrapped up 2025 with impressive growth, adding more than 4.6 million new active customers and expanding service to 35 additional countries, territories, and markets.
Starlink wrapped up 2025 with impressive growth, adding more than 4.6 million new active customers and expanding service to 35 additional countries, territories, and markets. The company also completed deployment of its first-generation Direct to Cell constellation, launching over 650 satellites in just 18 months to enable cellular connectivity.
SpaceX highlighted Starlink’s impressive 2025 progress in an extensive report.
Key achievements from Starlink’s 2025 Progress
Starlink connected over 4.6 million new customers with high-speed internet while bringing service to 35 more regions worldwide in 2025. Starlink is now connecting 9.2 million people worldwide. The service achieved this just weeks after hitting its 8 million customer milestone.
Starlink is now available in 155 markets, including areas that are unreachable by traditional ISPs. As per SpaceX, Starlink has also provided over 21 million airline passengers and 20 million cruise passengers with reliable high-speed internet connectivity during their travels.
Starlink Direct to Cell
Starlink’s Direct to Cell constellation, more than 650 satellites strong, has already connected over 12 million people at least once, marking a breakthrough in global mobile coverage.
Starlink Direct to Cell is currently rolled out to 22 countries and 6 continents, with over 6 million monthly customers. Starlink Direct to Cell also has 27 MNO partners to date.
“This year, SpaceX completed deployment of the first generation of the Starlink Direct to Cell constellation, with more than 650 satellites launched to low-Earth orbit in just 18 months. Starlink Direct to Cell has connected more than 12 million people, and counting, at least once, providing life-saving connectivity when people need it most,” SpaceX wrote.

Tesla Giga Nevada celebrates production of 6 millionth drive unit
To celebrate the milestone, the Giga Nevada team gathered for a celebratory group photo.
Tesla’s Giga Nevada has reached an impressive milestone, producing its 6 millionth drive unit as 2925 came to a close.
To celebrate the milestone, the Giga Nevada team gathered for a celebratory group photo.
6 million drive units
The achievement was shared by the official Tesla Manufacturing account on social media platform X. “Congratulations to the Giga Nevada team for producing their 6 millionth Drive Unit!” Tesla wrote.
The photo showed numerous factory workers assembled on the production floor, proudly holding golden balloons that spelled out “6000000″ in front of drive unit assembly stations. Elon Musk gave credit to the Giga Nevada team, writing, “Congrats on 6M drive units!” in a post on X.
Giga Nevada’s essential role
Giga Nevada produces drive units, battery packs, and energy products. The facility has been a cornerstone of Tesla’s scaling since opening, and it was the crucial facility that ultimately enabled Tesla to ramp the Model 3 and Model Y. Even today, it serves as Tesla’s core hub for battery and drivetrain components for vehicles that are produced in the United States.
Giga Nevada is expected to support Tesla’s ambitious 2026 targets, including the launch of vehicles like the Tesla Semi and the Cybercab. Tesla will have a very busy 2026, and based on Giga Nevada’s activities so far, it appears that the facility will be equally busy as well.

Tesla Supercharger network delivers record 6.7 TWh in 2025
The network now exceeds 75,000 stalls globally, and it supports even non-Tesla vehicles across several key markets.
Tesla’s Supercharger Network had its biggest year ever in 2025, delivering a record 6.7 TWh of electricity to vehicles worldwide.
To celebrate its busy year, the official @TeslaCharging account shared an infographic showing the Supercharger Network’s growth from near-zero in 2012 to this year’s impressive milestone.
Record 6.7 TWh delivered in 2025
The bar chart shows steady Supercharger energy delivery increases since 2012. Based on the graphic, the Supercharger Network started small in the mid-2010s and accelerated sharply after 2019, when the Model 3 was going mainstream.
Each year from 2020 onward showed significantly more energy delivery, with 2025’s four quarters combining for the highest total yet at 6.7 TWh.
This energy powered millions of charging sessions across Tesla’s growing fleet of vehicles worldwide. The network now exceeds 75,000 stalls globally, and it supports even non-Tesla vehicles across several key markets. This makes the Supercharger Network loved not just by Tesla owners but EV drivers as a whole.
Resilience after Supercharger team changes
2025’s record energy delivery comes despite earlier 2024 layoffs on the Supercharger team, which sparked concerns about the system’s expansion pace. Max de Zegher, Tesla Director of Charging North America, also highlighted that “Outside China, Superchargers delivered more energy than all other fast chargers combined.”
Longtime Tesla owner and FSD tester Whole Mars Catalog noted the achievement as proof of continued momentum post-layoffs. At the time of the Supercharger team’s layoffs in 2024, numerous critics were claiming that Elon Musk was halting the network’s expansion altogether, and that the team only remained because the adults in the room convinced the juvenile CEO to relent.
Such a scenario, at least based on the graphic posted by the Tesla Charging team on X, seems highly implausible.
