A press release has been sent out by Brandenburg about Tesla Gigafactory Berlin’s final approval. The following are some of the highlights from the document.
Potsdam/Frankfurt (Oder) – Today, Friday (March 4), the State Office for the Environment (LfU), which is responsible for immission control approval procedures, issued the approval for the Tesla factory in Grünheide (Oder-Spree district) in Brandenburg and handed it over to the project developer.
The approval notice will shortly be published in the official gazette for the state of Brandenburg, in the local daily newspapers and on the internet. The notice of approval is available for two weeks from the date of publication in the municipality of Grünheide (Mark), the town of Erkner, the Spreenhagen office and the seat of the administration of the Oder-Spree district in Beeskow as well as in the State Office for the Environment in Frankfurt (Oder) inspection off. The period of one month during which objections to the approval can be raised begins with the end of the exhibition. At the same time, the approval notice is published on the Internet on the EIA portal of the state of Brandenburg, where it can be viewed until the end of the objection period.
The project, which was approved with the 536-page decision, includes the plan for the production of up to 500,000 vehicles per year, aluminum smelting plants and an aluminum foundry, plants for surface treatment, heat generation, and storage. The facility also includes battery cell production, an operational wastewater treatment plant, a fire brigade equipment house, a high-bay warehouse, as well as laboratories and workshops.
The Tesla approval process is unusual in several ways. In a comparatively short time, the State Office for the Environment inspected and approved not just a factory, but an entire industrial area with several large-scale plants and repeated public participation.

06:55 a.m. PST – Grunheide Mayor Arne Christiani highlights that Tesla’s work is a Herculean task. He also points out that Giga Berlin will provide opportunities, particularly jobs, in the area. Commenting on how the electric vehicle facility could benefit the region, the official stated that Tesla bringing Giga Berlin to the area is similar to “winning the lottery.”
06:52 a.m. PST – Jorg Steinbach takes the stage. He speaks about how important Giga Berlin is to the region. Brandenburg, after all, was not that prolific for high-profile investments before. With Tesla’s Gigafactory Berlin, the state is now high on the list of locations that companies are looking at for industrial projects. Tesla’s presence has already signaled the development of an entire integrated supply chain.
06:50 a.m. PST – With the final approval now secured, Tesla now has to secure its operational permit for Giga Berlin’s Model Y production. About 400 conditions and requirements have been defined in the permit, which may seem like a lot, but are really not many, according to Vogel. The permit includes 23,700 pages of applications (HT Alex Voigt).
06:49 a.m. PST – Vogel reiterates that the final permit for Gigafactory Berlin is an “intermediate step.” He also praised those who were responsible for the approval of Giga Berlin, as they did not lose sight despite all the noise surrounding the project. “Those responsible for the approval have not been deterred by the media and political attention to the project. [We] have checked the approval requirements in this process,” Vogel remarked.
06:48 a.m. PST – Alex Vogel takes the stage and discusses the meticulous process involved in the approval of Gigafactory Berlin. “It couldn’t have been done faster, but we have to say that every procedure was carried out within the framework for federal German law approval,” he said.
06:46 a.m. PST – The Minister-President did highlight, however, that while the approval of Tesla Giga Berlin is a good day for the state of Brandenburg, it should not take away from the grave situation in Ukraine, which is currently being attacked by Russia. “I very much hope that this criminal attack by Putin on Ukraine will end as quickly as possible,” Woidke said.
06:45 a.m. PST – Minister-President Woidke highlights that the approval process of Giga Berlin was a challenge for Germany. “You know (this) was also doubted across Germany at the time. Is it even possible in Germany to meet the requirements, is it possible within two years to get the third-largest automobile factory in Germany (approved)? That’s what we’re talking about there, after all, building it up and making it a success…. I learned a lot from this project, yes. I also learned that (while) planning and approval is possible in Germany, I also have to change a lot. That is a discussion that we will continue at the federal level,” the Minister-President said.

06:40 a.m. PST – Minister-President Woidke notes that the approval of Giga Berlin was a mammoth task for Brandenburg. “I do believe that today, this March 4th, is a big step into the future for Brandenburg… I’m firmly convinced that in 20, 30, 40 years, if you look at the history of Brandenburg, there will be a time before Tesla and a time with Tesla,” Woidke said.
06:35 a.m. PST – Minister-President Woidke confirmed that the final construction permit for Gigafactory Berlin has been issued and given to Tesla.
06:30 a.m. PST – The press conference begins. Introductions are made. Brandenburg Minister-President Dietmar Woidke’s Tesla Team are introduced. Appreciation is extended to every member of “Task Force Tesla,” as each one was pivotal in getting the facility’s approvals passed.

Tesla confirms that it finally solved its 4680 battery’s dry cathode process
The suggests the company has finally resolved one of the most challenging aspects of its next-generation battery cells.
Tesla has confirmed that it is now producing both the anode and cathode of its 4680 battery cells using a dry-electrode process, marking a key breakthrough in a technology the company has been working to industrialize for years.
The update, disclosed in Tesla’s Q4 and FY 2025 update letter, suggests the company has finally resolved one of the most challenging aspects of its next-generation battery cells.
Dry cathode 4680 cells
In its Q4 and FY 2025 update letter, Tesla stated that it is now producing 4680 cells whose anode and cathode were produced during the dry electrode process. The confirmation addresses long-standing questions around whether Tesla could bring its dry cathode process into sustained production.
The disclosure was highlighted on X by Bonne Eggleston, Tesla’s Vice President of 4680 batteries, who wrote that “both electrodes use our dry process.”
Tesla first introduced the dry-electrode concept during its Battery Day presentation in 2020, pitching it as a way to simplify production, reduce factory footprint, lower costs, and improve energy density. While Tesla has been producing 4680 cells for some time, the company had previously relied on more conventional approaches for parts of the process, leading to questions about whether a full dry-electrode process could even be achieved.
4680 packs for Model Y
Tesla also revealed in its Q4 and FY 2025 Update Letter that it has begun producing battery packs for certain Model Y vehicles using its in-house 4680 cells. As per Tesla:
“We have begun to produce battery packs for certain Model Ys with our 4680 cells, unlocking an additional vector of supply to help navigate increasingly complex supply chain challenges caused by trade barriers and tariff risks.”
The timing is notable. With Tesla preparing to wind down Model S and Model X production, the Model Y and Model 3 are expected to account for an even larger share of the company’s vehicle output. Ensuring that the Model Y can be equipped with domestically produced 4680 battery packs gives Tesla greater flexibility to maintain production volumes in the United States, even as global battery supply chains face increasing complexity.

Tesla Giga Texas to feature massive Optimus V4 production line
This suggests that while the first Optimus line will be set up in the Fremont Factory, the real ramp of Optimus’ production will happen in Giga Texas.
Tesla will build Optimus 4 in Giga Texas, and its production line will be massive. This was, at least, as per recent comments by CEO Elon Musk on social media platform X.
Optimus 4 production
In response to a post on X which expressed surprise that Optimus will be produced in California, Musk stated that “Optimus 4 will be built in Texas at much higher volume.” This suggests that while the first Optimus line will be set up in the Fremont Factory, and while the line itself will be capable of producing 1 million humanoid robots per year, the real ramp of Optimus’ production will happen in Giga Texas.
This was not the first time that Elon Musk shared his plans for Optimus’ production at Gigafactory Texas. During the 2025 Annual Shareholder Meeting, he stated that Giga Texas’ Optimus line will produce 10 million units of the humanoid robot per year. He did not, however, state at the time that Giga Texas would produce Optimus V4.
“So we’re going to launch on the fastest production ramp of any product of any large complex manufactured product ever, starting with building a one-million-unit production line in Fremont. And that’s Line one. And then a ten million unit per year production line here,” Musk stated.
How big Optimus could become
During Tesla’s Q4 and FY 2025 earnings call, Musk offered additional context on the potential of Optimus. While he stated that the ramp of Optimus’ production will be deliberate at first, the humanoid robot itself will have the potential to change the world.
“Optimus really will be a general-purpose robot that can learn by observing human behavior. You can demonstrate a task or verbally describe a task or show it a task. Even show it a video, it will be able to do that task. It’s going to be a very capable robot. I think long-term Optimus will have a very significant impact on the US GDP.
“It will actually move the needle on US GDP significantly. In conclusion, there are still many who doubt our ambitions for creating amazing abundance. We are confident it can be done, and we are making the right moves technologically to ensure that it does. Tesla, Inc. has never been a company to shy away from solving the hardest problems,” Musk stated.

Rumored SpaceX-xAI merger gets apparent confirmation from Elon Musk
The comment follows reports that the rocket maker is weighing a transaction that could further consolidate Musk’s space and AI ventures.
Elon Musk appeared to confirm reports that SpaceX is exploring a potential merger with artificial intelligence startup xAI by responding positively to a post about the reported transaction on X.
Musk’s comment follows reports that the rocket maker is weighing a transaction that could further consolidate his space and AI ventures.
SpaceX xAI merger
As per a recent Reuters report, SpaceX has held discussions about merging with xAI, with the proposed structure potentially involving an exchange of xAI shares for SpaceX stock. The value, structure, and timing of any deal have not been finalized, and no agreement has been signed.
Musk appeared to acknowledge the report in a brief reply on X, responding “Yeah” to a post that described SpaceX as a future “Dyson Swarm company.” The comment references a Dyson Swarm, a sci-fi megastructure concept that consists of a massive network of satellites or structures that orbit a celestial body to harness its energy.
Reuters noted that two entities were formed in Nevada on January 21 to facilitate a potential transaction for the possible SpaceX-xAI merger. The discussions remain ongoing, and a transaction is not yet guaranteed, however.
AI and space infrastructure
A potential merger with xAI would align with Musk’s stated strategy of integrating artificial intelligence development with space-based systems. Musk has previously said that space-based infrastructure could support large-scale computing by leveraging continuous solar energy, an approach he has framed as economically scalable over time.
xAI already has operational ties to Musk’s other companies. The startup develops Grok, a large language model that holds a U.S. Department of Defense contract valued at up to $200 million. AI also plays a central role in SpaceX’s Starlink and Starshield satellite programs, which rely on automation and machine learning for network management and national security applications.
Musk has previously consolidated his businesses through share-based transactions, including Tesla’s acquisition of SolarCity in 2016 and xAI’s acquisition of X last year. Bloomberg has also claimed that Musk is considering a merger between SpaceX and Tesla in the future.
