Tesla Gigafactory Berlin is about to receive its final environmental approval, with Brandenburg Minister-President Dietmar Woidke holding a press conference later today to discuss the milestone. It took a long time to get to this point, but after two years, it appears that Tesla’s Model Y factory in Germany is finally about to wake up.
Information shared with Teslarati indicates that the press conference later will be attended not only by Brandenburg Minister-President Dietmar Woidke. Other key personalities in Giga Berlin’s development such as Environment Minister Axel Vogel and Economics Minister Jörg Steinbach (SPD) will also be present at the event.
Ulrich Stock, the department head responsible in the State Office for the Environment, Sascha Gehm, the First Deputy of the Oder-Spree district, and Arne Christiani, the Mayor of Grünheide, are also expected to be present at the press conference.
A quick refresher of what’s been happening in Giga Berlin can be found below.
Another permit after the final environmental approval
It should be noted that the final environmental approval is a massive step forward for Gigafactory Berlin. However, the final environmental approval does not mean that vehicle production could immediately start. An operating license is still required before Model Ys can be produced. Tesla must then meet further requirements before Giga Berlin’s Model Y production lines could start operations.
Teslarati has contacted several local government offices to inquire about the requirements that Tesla needs to submit to secure Giga Berlin’s operational license for vehicle production. Local government offices have so far declined to provide additional information, at least for now.
An ongoing water dispute
Giga Berlin has a lot of critics, and it has faced opposition over the years. Among the most notable talking points against Giga Berlin as of late is its water supply. Conservationists and local resident groups have expressed their fear that Giga Berlin will put the local water supply at risk. Legal action has been taken about the issue. Local water association Strausberg-Erkner (WSE) believes that Tesla’s water supply for Giga Berlin could still be terminated, but such a development may result in Tesla taking legal action.
Tesla is set to receive a supply of 1.4 million cubic liters of drinking water every year, though this may increase as Gigafactory Berlin expands its operations. It should be noted that a nearby coal mine and an oil refinery in the area are consuming far more water annually than Tesla. CEO Elon Musk has also said that Tesla will “recycle as much as humanly possible,” adding that he’s “pretty confident that (Giga Berlin) will be the most environmentally friendly factory in the world.”
A summary of delays
Gigafactory Berlin started its construction about two years ago, and initially, the facility seemed to be progressing at around the same pace as its sibling, Gigafactory Shanghai. Tesla also planned to start vehicle production in summer 2021, a target that was ultimately not met. This was partly due to several delays, which included a time when construction had to be paused due to hibernating snakes in the area. Tesla also faced much opposition from environmentalist groups who opposed the tree-cutting on the site. The EV maker responded by planting more trees than it had cut.
Even Tesla itself became a source of delays for the launch of Giga Berlin. Tesla moves at a very quick pace, and it updates its plans for its facilities accordingly. In Giga Berlin’s case, the company decided to add the construction and operation of a battery factory. This resulted in Giga Berlin’s applications requiring updates, causing further delays. Thankfully, most of Giga Berlin’s delays seem to have been dealt with for now, and the facility is in its final stages before it could start its operations.
Future plans
Tesla’s Gigafactories are ever-developing, and the same is true for Giga Berlin. As per information shared with German news agency rbb24, new applications for further expansion are expected to be submitted soon. Battery recycling facilities are also reportedly planned for the site, and so is a production line for Powerwall batteries, which may be equipped with cells that are produced in the Giga Berlin complex. Teslarati has attempted to confirm these reports, but local office representatives have declined to comment on the matter.
Giga Berlin’s press conference for the facility’s final environmental approval is expected to start at 3:30 p.m. CET (6:30 a.m. PST).

Tesla hints at Starlink integration with recent patent
“By employing polymer blends, some examples enable RF transmission from all the modules to satellites and other communication devices both inside and outside the vehicle.”
Tesla hinted at a potential Starlink internet terminal integration within its vehicles in a recent patent, which describes a vehicle roof assembly with integrated radio frequency (RF) transparency.
The patent, which is Pub. No U.S. 2025/0368267 describes a new vehicle roof that is made of RF-transparent polymer materials, allowing and “facilitating clear communication with external devices and satellites.”
Tesla believes that a new vehicle roof design, comprised of different materials than the standard metallic or glass elements used in cars today, would allow the company to integrate modern vehicular technologies, “particularly those requiring radio frequency transmission and reception.
Tesla has recently filed a US patent application on integrating RF transparent materials into the roof structure.

Instead of glass or metallic materials, Tesla says vehicles may benefit from high-strength polymer blends, such as Polycarbonate, Acrylonitrile Butadiene Styrene, or Acrylonitrile Styrene Acrylate.
These materials still provide ideal strength metrics for crashworthiness, stiffness for noise, vibration, and harshness control, and are compliant with head impact regulations.
They would also enable better performance with modern technologies, like internet terminals, which need an uninterrupted signal to satellites for maximum reception. Tesla writes in the patent:
“By employing polymer blends, some examples enable RF transmission from all the modules to satellites and other communication devices both inside and outside the vehicle.”
One of the challenges Tesla seems to be aware of with this type of roof design is the fact that it will still have to enable safety and keep that at the forefront of the design. As you can see in the illustration above, Tesla plans to use four layers to increase safety and rigidity, while also combating noise and vibration.
It notes in the patent that disclosed examples still meet the safety requirements outlined in the Federal Motor Vehicle Safety Standards (FMVSS).
Starlink integrated directly into Tesla vehicles would be a considerable advantage for owners. It would come with a handful of distinct advantages.
Initially, the inclusion of Starlink would completely eliminate cellular dead zones, something that is an issue, especially in rural areas. Starlink would provide connectivity in these remote regions and would ensure uninterrupted service during road trips and off-grid adventures.
It could also be a critical addition for Robotaxi, as it is crucial to have solid and reliable connectivity for remote monitoring and fleet management.
Starlink’s growing constellation, thanks to SpaceX’s routine and frequent launch schedule, will provide secure, stable, and reliable internet connectivity for Tesla vehicles.
Although many owners have already mounted Starlink Mini dishes under their glass roofs for a similar experience, it may be integrated directly into Teslas in the coming years, either as an upgrade or a standard feature.

Tesla supplements Holiday Update by sneaking in new Full Self-Driving version
It seems Tesla was waiting for the Hardware 4 rollout, as it wanted to also deploy a new Full Self-Driving version to those owners, as it appeared in the release notes for the Holiday Update last night.
Tesla has surprised some owners by sneaking in a new Full Self-Driving version with the wide release of the Holiday Update, which started rolling out to Hardware 4 owners on Friday night.
Tesla has issued a controlled and very slow release pattern with the Holiday Update, which rolls out with Software Version 2025.44.25.5.
For the past two weeks, as it has rolled out to Hardware 3 and older Tesla owners, the company has kept its deployment of the new Software Version relatively controlled.
It seems Tesla was waiting for the Hardware 4 rollout, as it wanted to also deploy a new Full Self-Driving version to those owners, as it appeared in the release notes for the Holiday Update last night.
Tesla Full Self-Driving v14.2.1.25 made its first appearance last night to Hardware 4 owners who are members of the Early Access Program (EAP). It appears to be a slight refinement from FSD v14.2.1, which has been out for a couple of weeks.

Many owners welcome the new FSD version, us included, because we’ve been less than impressed with v14.2.1. We have experienced some minor regressions with v14.2.1, especially with Speed Limit recognition, Speed Profile tinkering, and parking performance.
As it stands, Full Self-Driving is still particularly impressive, but Tesla is evidently having an issue with some of the adjustments, as it is still refining some of the performance aspects of the suite. This is expected and normal with some updates, as not all of them are an improvement in all areas; we routinely see some things backtrack every once in a while.
This new FSD version is likely to take care of those things, but it also includes all of the awesome Holiday Update features, which include:
- Grok with Navigation Commands (Beta) – Grok will now add and edit destinations.
- Tesla Photobooth – Take pictures inside your car using the cabin-facing camera
- Dog Mode Live Activity – Check on your four-legged friend on your phone through periodic snapshots taken of the cabin
- Dashcam Viewer Update – Includes new metrics, like steering wheel angle, speed, and more
- Santa Mode – New graphics, trees, and a lock chime
- Light Show Update – Addition of Jingle Rush light show
- Custom Wraps and License Plates – Colorizer now allows you to customize your vehicle even further, with custom patterns, license plates, and tint
- Navigation Improvements – Easier layout and setup
- Supercharger Site Map – Starting at 18 pilot locations, a 3D view of the Supercharger you’re visiting will be available
- Automatic Carpool Lane Routing – Navigation will utilize carpool lanes if enabled
- Phone Left Behind Chime – Your car will now tell you if you left a phone inside
- Charge Limit Per Location – Set a charge limit for each location
- ISS Docking Simulator – New game
- Additional Improvements – Turn off wireless charging pad, Spotify improvements, Rainbow Rave Cave, Lock Sound TRON addition
Tesla also added two other things that were undocumented, like Charging Passport and information on USB drive storage to help with Dashcam.
Tesla is updating Cybertruck owners on its timeline of a massive feature that has yet to ship: Powershare with Powerwall.
Powershare is a bidirectional charging feature exclusive to Cybertruck, which allows the vehicle’s battery to act as a portable power source for homes, appliances, tools, other EVs, and more. It was announced in late 2023 as part of Tesla’s push into vehicle-to-everything energy sharing, and acting as a giant portable charger is the main advantage, as it can provide backup power during outages.
Cybertruck’s Powershare system supports both vehicle-to-load (V2L) and vehicle-to-home (V2H), making it flexible and well-rounded for a variety of applications.
However, even though the feature was promised with Cybertruck, it has yet to be shipped to vehicles. Tesla communicated with owners through email recently regarding Powershare with Powerwall, which essentially has the pickup act as an extended battery.
Powerwall discharge would be prioritized before tapping into the truck’s larger pack.
However, Tesla is still working on getting the feature out to owners, an email said:
“We’re writing to let you know that the Powershare with Powerwall feature is still in development and is now scheduled for release in mid-2026.
This new release date gives us additional time to design and test this feature, ensuring its ability to communicate and optimize energy sharing between your vehicle and many configurations and generations of Powerwall. We are also using this time to develop additional Powershare features that will help us continue to accelerate the world’s transition to sustainable energy.”
Owners have expressed some real disappointment in Tesla’s continuous delays in releasing the feature, as it was expected to be released by late 2024, but now has been pushed back several times to mid-2026, according to the email.
Foundation Series Cybertruck buyers paid extra, expecting the feature to be rolled out with their vehicle upon pickup.
Cybertruck’s Lead Engineer, Wes Morrill, even commented on the holdup:
As a Cybertruck owner who also has Powerwall, I empathize with the disappointed comments.
To their credit, the team has delivered powershare functionality to Cybertruck customers who otherwise have no backup with development of the powershare gateway. As well as those with solar…
— Wes (@wmorrill3) December 12, 2025
He said that “it turned out to be much harder than anticipated to make powershare work seamlessly with existing Powerwalls through existing wall connectors. Two grid-forming devices need to negotiate who will form and who will follow, depending on the state of charge of each, and they need to do this without a network and through multiple generations of hardware, and test and validate this process through rigorous certifications to ensure grid safety.”
It’s nice to see the transparency, but it is justified for some Cybertruck owners to feel like they’ve been bait-and-switched.
