Liebherr electric excavator reaches million ton milestone, scores more orders
This massive Liebherr electric excavator reached a major operational milestone earlier this month when it moved its one millionth tonne of dirt. And now, its buyers want more!
That’s right, gang – since we first covered the converted mining excavator back in January it’s been hard at work. And now, after its initial 90 day “break-in” period operating at partial capacity while the site team familiarized themselves with the new tech, it’s operating at full speed at Fortescue’s Christmas Creek mine in Western Australia.
The Liebherr is working so well, in fact, that Fortescue is planning on order two more examples of the mighty electric earth-mover.
“This is such an exciting milestone for Fortescue and our decarbonisation journey. Importantly, we’ve been able to achieve this while maintaining our high safety standards,” says Fortescue Metals CEO, Dino Otranto. “We will have two additional electric excavators commissioned by the end of April. Once we decarbonize our entire fleet, around 95 million liters of diesel will be removed from our operations every year, or more than a quarter of a million tonnes of carbon dioxide equivalent.”
Big work needs big power
Moving more than a million tons of earth and rock takes a lot of energy. To keep its batteries topped off, the re-powered Liebherr R 9400 E electric excavator operates off blend of renewable solar power and a 6.6 kV substation pumping electrons through more than two kilometers of high voltage trailing cable.
Eventually, though, Fortescue plans to power its equipment completely from sustainable sources. “In line with our commitment to eliminate emissions across our mining operations,” reads the company’s statement. “The intention is that all electrified mining equipment will eventually be 100 per cent powered by renewable electricity.”
Electrek’s Take
Covering an electric pilot program is always fun, but all too often the results of these initial experiments aren’t publicized – or else, don’t directly lead to sales. To their credit, Liebherr is lucky to have a customer in Fortescue that’s willing to put their cards on the table here, trumpeting the re-powered excavator’s success and even announcing its plans to order two more electric machines publicly.
They won’t have to wait long, either. Because Liebherr takes a modular approach to building its larger mining equipment, a diesel-drive excavator like the R 9400 can be completely re-powered to electric in a matter of weeks.

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.
