Top 6 tidbits about Tesla’s Gigafactory revealed through building permits
It’s no secret that Tesla’s $5 billion dollar Gigafactory 1 located just east of Reno, Nevada will be a critical component to the company’s goal of scaling mass production of batteries for its upcoming Model 3 and Tesla Energy product line. We know the Gigafactory will be one of the largest buildings in the world projected to occupy 13.6 million square feet, and we know the factory will be powered by renewable energy sources, with the goal of achieving net zero energy. However, construction permits filed by Tesla provide even more interesting insight to Gigafactory 1 that you may not already know.
Here are the top 6 tidbits of Tesla’s Gigafactory as revealed through building permits received by Tesla. Information is provided courtesy of analyst Jack Cookson of BuildingZoom.
1) July 29 launch event attendees may witness battery cells being made
Construction permit #0934363 indicates that the $51 million dollar “Battery Cell Manufacturing Equipment Installation” project is estimated to be complete on July 20th. This means that attendees of the highly anticipated July 29 Gigafactory ‘Grand Opening’ event may actually have the opportunity to see battery cells being manufactured.
2) Tesla can do it all
Tesla filed for building permits themselves as opposed to using a General Contractor. According to a report put together by Cookson of BuildZoom,
“Something we found different about this project is that Tesla filed the majority of their own building permits and is actually the contractor for the project. This means, that Tesla had to acquire a contractor license in Nevada and has taken on far more work than if they had just hired a General Contractor.”
This may not be such a bad idea considering Tesla’s recent involvement in a foreign worker scandal under poor supervision and management by factory sub-contractors.
-->3) Tesla’s Gigafactory is designed for earthquakes
Most buildings rest on a single foundation, however the enormous rectangular shaped Gigafactory rests on four individual foundations. This is designed so that each section of the building can shift independently of one another in the event of an earthquake.
4) The Gigafactory doesn’t stop growing
Tesla received a permit to expand the Gigafactory with a 4th Area ‘D’ and 5th Area ‘E’. The $63 million dollar D and E project is scheduled to be complete by the end of the year. Tesla’s enormous Gigafactory is currently only 14% of the total planned floor space, but will reach an astounding 13.6 million square feet when complete.

5) Tesla donated a fire truck to the local fire department
Tesla spent a total of $4.7 million dollars on fire safety, including a permit for a fire command center. Part of that included a donation of a fire engine to the local Storey County, Nevada fire station.
6) Giant refrigerator + water tank twice the size of an olympic pool
1 of the 84 permits filed indicates that the Gigafactory will have a giant chiller yard which will presumably be used for testing batteries while keeping them in a cool state.
The factory also has a a 1.5 million gallon water tank on site that is more than twice the size of an olympic sized swimming pool. Details within the permit do not indicate what this water tank will be used for.

Elon Musk makes a key Tesla Optimus detail official
“Since we are naming the singular, we will also name the plural, so Optimi it is,” Musk wrote on X.
Tesla CEO Elon Musk just made a key detail about Optimus official. In a post on X, the CEO clarified some key wording about Optimus, which should help the media and the public become more familiar with the humanoid robot.
Elon Musk makes Optimus’ plural term official
Elon Musk posted a number of Optimus-related posts on X this weekend. On Saturday, he stated that Optimus would be the Von Neumann probe, a machine that could eventually be capable of replicating itself. This capability, it seems, would be the key to Tesla achieving Elon Musk’s ambitious Optimus production targets.
Amidst the conversations about Optimus on X, a user of the social media platform asked the CEO what the plural term for the humanoid robot will be. As per Musk, Tesla will be setting the plural term for Optimus since the company also decided on the robot’s singular term. “Since we are naming the singular, we will also name the plural, so Optimi it is,” Musk wrote in his reply on X.
This makes it official. For media outlets such as Teslarati, numerous Optimus bots are now called Optimi. It rolls off the tongue pretty well, too.
Optimi will be a common sight worldwide
While Musk’s comment may seem pretty mundane to some, it is actually very important. Optimus is intended to be Tesla’s highest volume product, with the CEO estimating that the humanoid robot could eventually see annual production rates in the hundreds of millions, perhaps even more. Since Optimi will be a very common sight worldwide, it is good that people can now get used to terms describing the humanoid robot.
-->During the Tesla 2025 Annual Shareholder Meeting, Musk stated that the humanoid robot will see “the fastest production ramp of any product of any large complex manufactured product ever,” starting with a one-million-Optimi-per-year production line at the Fremont Factory. Giga Texas would get an even bigger Optimus production line, which should be capable of producing tens of millions of Optimi per year.

Tesla is improving Giga Berlin’s free “Giga Train” service for employees
With this initiative, Tesla aims to boost the number of Gigafactory Berlin employees commuting by rail while keeping the shuttle free for all riders.
Tesla will expand its factory shuttle service in Germany beginning January 4, adding direct rail trips from Berlin Ostbahnhof to Giga Berlin-Brandenburg in Grünheide.
With this initiative, Tesla aims to boost the number of Gigafactory Berlin employees commuting by rail while keeping the shuttle free for all riders.
New shuttle route
As noted in a report from rbb24, the updated service, which will start January 4, will run between the Berlin Ostbahnhof East Station and the Erkner Station at the Gigafactory Berlin complex. Tesla stated that the timetable mirrors shift changes for the facility’s employees, and similar to before, the service will be completely free. The train will offer six direct trips per day as well.
“The service includes six daily trips, which also cover our shift times. The trains will run between Berlin Ostbahnhof (with a stop at Ostkreuz) and Erkner station to the Gigafactory,” Tesla Germany stated.
Even with construction continuing at Fangschleuse and Köpenick stations, the company said the route has been optimized to maintain a predictable 35-minute travel time. The update follows earlier phases of Tesla’s “Giga Train” program, which initially connected Erkner to the factory grounds before expanding to Berlin-Lichtenberg.
-->Tesla pushes for majority rail commuting
Tesla began production at Grünheide in March 2022, and the factory’s workforce has since grown to around 11,500 employees, with an estimated 60% commuting from Berlin. The facility produces the Model Y, Tesla’s best-selling vehicle, for both Germany and other territories.
The company has repeatedly emphasized its goal of having more than half its staff use public transportation rather than cars, positioning the shuttle as a key part of that initiative. In keeping with the factory’s sustainability focus, Tesla continues to allow even non-employees to ride the shuttle free of charge, making it a broader mobility option for the area.

Tesla Model 3 and Model Y dominate China’s real-world efficiency tests
The Tesla Model 3 posted 20.8 kWh/100 km while the Model Y followed closely at 21.8 kWh/100 km.
Tesla’s Model 3 and Model Y once again led the field in a new real-world energy-consumption test conducted by China’s Autohome, outperforming numerous rival electric vehicles in controlled conditions.
The results, which placed both Teslas in the top two spots, prompted Xiaomi CEO Lei Jun to acknowledge Tesla’s efficiency advantage while noting that his company’s vehicles will continue refining its own models to close the gap.
Tesla secures top efficiency results
Autohome’s evaluation placed all vehicles under identical conditions, such as a full 375-kg load, cabin temperature fixed at 24°C on automatic climate control, and a steady cruising speed of 120 km/h. In this environment, the Tesla Model 3 posted 20.8 kWh/100 km while the Model Y followed closely at 21.8 kWh/100 km, as noted in a Sina News report.
These figures positioned Tesla’s vehicles firmly at the top of the ranking and highlighted their continued leadership in long-range efficiency. The test also highlighted how drivetrain optimization, software management, and aerodynamic profiles remain key differentiators in high-speed, cold-weather scenarios where many electric cars struggle to maintain low consumption.
Xiaomi’s Lei Jun pledges to continue learning from Tesla
Following the results, Xiaomi CEO Lei Jun noted that the Xiaomi SU7 actually performed well overall but naturally consumed more energy due to its larger C-segment footprint and higher specification. He reiterated that factors such as size and weight contributed to the difference in real-world consumption compared to Tesla. Still, the executive noted that Xiaomi will continue to learn from the veteran EV maker.
“The Xiaomi SU7’s energy consumption performance is also very good; you can take a closer look. The fact that its test results are weaker than Tesla’s is partly due to objective reasons: the Xiaomi SU7 is a C-segment car, larger and with higher specifications, making it heavier and naturally increasing energy consumption. Of course, we will continue to learn from Tesla and further optimize its energy consumption performance!” Lei Jun wrote in a post on Weibo.
-->Lei Jun has repeatedly described Tesla as the global benchmark for EV efficiency, previously stating that Xiaomi may require three to five years to match its leadership. He has also been very supportive of FSD, even testing the system in the United States.
