Tesla finally moves forward with Gigafactory Nevada expansion for Tesla Semi and 4680 cells
Tesla finally moved forward with Gigafactory Nevada expansion for Tesla Semi and 4680 cells a year after the original announcement.
Tesla Gigafactory Nevada was the first major step in Tesla’s effort to secure battery cell supply for its ambitious growth.
The automaker partnered with Panasonic to deploy new battery cell production capacity at the facility, and Tesla used those cells to build battery packs for its vehicles and energy storage products.
When originally announcing the plan for the factory, Tesla was talking about the plant producing 105 GWh of battery cells per year and 150 GWh of battery packs per year once completed.
It was supposed to become the largest building in the world.
However, the factory is currently about 30% complete, and Tesla hasn’t expanded the facility for years as both the automaker and Panasonic have focused on optimizing the current production capacity.
Here’s what the factory is supposed to look like once completed (yellow) and the existing sections with Tesla’s operations (red) and Panasonic’s (blue):
Tesla hasn’t expanded the footprint of the factory in five years at this point, as it focused on optimizing this one and building new ones that include vertically-integrated vehicle production.
In January 2023, Tesla announced a massive expansion of Gigafactory Nevada to add production of Tesla Semi trucks and 4680 battery cells and to finally expand the factory to its originally planned size.
The goal is to build the Tesla Semi in volume at the plant along with the 4680 battery cell, which powers the electric truck and new Tesla vehicles.
Tesla released this updated image of the planned final plant:
The company is generally known to move quickly after such announcements, but it didn’t do anything for a year.
Today, we learn that Tesla is finally starting to get some construction, or at least earth-moving, work done for the Gigafactory Nevada expansion.
Youtuber ‘Zanegler Tesla Semi Stalker’ posted a new drone flyby of the factory and in the video, he claimed that Tesla held a “groundbreaking ceremony” for the expansion on Wednesday.
We couldn’t confirm that, but the video does show Tesla moving ground for some construction work:
However, it doesn’t look like Tesla is working on the previously announced expansion with new sections of the existing building.
The new work is being done outside of the originally planned area:
It’s possible that Tesla is working on the land for a new parking lot as it will need to move the existing one if it goes through with these plans.
The Youtuber said that Tesla told employees at the groundbreaking event that the new section for Tesla Semi is actually going to be a new building separate to the existing one, but we can’t confirm that.
Either way, some work is at least being done.
Last year, we reported that Tesla hired a new manufacturing executive from Eli Lily to lead its elusive Gigafactory Nevada expansion. It’s possible that the plans have changed a lot since then.

Electricity demand is surging in Texas, and solar, wind, and battery storage are meeting it.
According to new data from the US Energy Information Administration (EIA), electricity demand across the Texas grid managed by the Electric Reliability Council of Texas (ERCOT) hit record highs in the first nine months of 2025. ERCOT, which supplies power to about 90% of the state, saw demand jump 5% year-over-year to 372 terawatt hours (TWh) – a 23% increase since 2021. No other major US grid has grown faster over the past year.
Solar and wind keep ERCOT’s grid steady
The biggest growth story in Texas power generation is solar. Utility-scale solar plants produced 45 TWh from January through September, up 50% from 2024 and nearly four times what they generated in 2021 (11 TWh). Wind power also continued to climb, producing 87 TWh through September – a 4% increase from last year and 36% more than in 2021.
Together, wind and solar supplied 36% of ERCOT’s total electricity over those nine months. Solar, in particular, has transformed Texas’s daytime energy mix. From June to September, ERCOT solar farms generated an average of 24 gigawatts (GW) between noon and 1 pm – double the midday output from 2023. That growth has pushed down natural gas use at midday from 50% of the mix in 2023 to 37% this year.
Battery storage is filling in the gaps
Batteries charge during the day when wind and solar generation are the highest, and they produce electricity when generation from wind and solar slows down. ERCOT began reporting battery output separately in October 2024 in its hourly grid data, and it’s clear that batteries are now helping to smooth out evening peaks. This past summer, batteries supplied an average of 4 GW of power around 8 pm, right as solar production dropped off.
Natural gas is flatlining
Natural gas is still Texas’s dominant power source, but it isn’t growing like it used to. Between January and September, gas-fired plants generated 158 TWh of electricity, compared to 161 TWh in 2023. Gas comprised 43% of ERCOT’s generation mix during the first nine months of 2025, down from 47% in the first nine months of 2023 and 2024.
More demand growth ahead
The EIA expects Texas electricity demand to keep rising faster than any other grid in the US. In its latest Short-Term Energy Outlook, the EIA projects ERCOT’s demand will climb another 14% in the first nine months of 2026, reaching 425 TWh. That means Texas will need even more solar, wind, and battery storage to keep up with its breakneck growth.

GM is recalling nearly 23,000 Chevy Equinox EV and Cadillac Optiq models due to a defect where the tire tread could fall off.
GM is recalling more Chevy Equinox EV models
In a letter sent to the National Highway Traffic Safety Administration (NHTSA), GM said it has decided to issue a safety recall for certain Chevy Equinox EV and Cadillac Optiq models from model years 2025 to 2026.
This time, it isn’t necessarily GM’s fault. The vehicles may be equipped with 21″ all-season tires that Continental Tire is recalling.
According to Continental, the tires were produced during the week of October 6, 2024, and may have a defect where the tire tread could partially or fully detach. The records show the defect is due to a nonconforming tread base rubber compound.
Owners of affected vehicles may notice unusual tread wear or bulging, vibration while driving, or tire noises. GM is unaware of any incidents related to the defect, but is issuing the recall out of an abundance of caution.
On September 18, 2025, GM inspected the assembly plant and confirmed there were no suspect tires in stock. The 21″ tires come standard on RS trims and are optional on LT1 and LT2 grades.
Although GM is recalling 22,914 Chevy Equinox EVs and Cadillac Optiqs, it estimates that only about 1% of them have the defect.
The recall includes:
- 2026 Cadillac Optiq: 214
- 2026 Chevy Equinox EV: 1,832
- 2025 Cadillac Optiq: 3,468
- 2025 Chevy Equinox EV: 17,400
GM dealers will check all four tires and replace them if needed, free of charge. Dealers were notified on October 16. Owner notification letters are expected to be mailed out on December 1, 2025.
You can contact Chevrolet’s customer service number at 1-800-222-1020 or Cadillac’s at 1-800-333-4223. GM’s recall number is N252525030. Owners can also call the NHTSA hotline at 1-888-327-4236 or visit the nhtsa.gov website for more information.
The Chevy Equinox EV is now the third best-selling EV in the US, trailing only the Tesla Model Y and Model 3. Meanwhile, Cadillac’s entry-level Optiq SUV is the fifth-most-popular luxury EV. The recall is minor and only affects a small percentage of models, so it’s not expected to have a major impact.
If you want to test one of them for yourself, we can help you get started. Check out our links below to find available Chevy Equinox EV and Cadillac Optiq models near you.
