Located in Perth, Western Australia, EPCA became famous for its “Green Machine,” a CAT 777 100-ton haul truck it converted to electric power. Now, the company says it has plans to produce 50-70 more of the battery electric mining trucks … each year.

After showcasing its Green Machine at two major mining events in Australia recently, EPCA (an acronym that stands for Electric Power Conversion Australia) a recent case study commissioned by one of the company’s key suppliers says it has plans to produce 50-70 of its 100-ton battery electric mining trucks annually.

There might be demand, too. Switching the CAT from diesel to battery electric power boosts the haul truck’s horsepower from 1,000 hp to 1,120 hp, and bumps torque from 4,700 Nm (3,400 lb ft) to 5,200 Nm (3,835 lb ft), and that torque increase comes at 0 rpm.

The electrons powering those motors are provided courtesy of six 290 kWh Xerotech batteries running in parallel. The combined battery pack is good for some 1740 kWh of energy storage, which makes it one of the biggest vehicle batteries we’ve ever heard of.

For their part, the EPCA team seem pretty proud of their new truck. Clayton Franklin, Chief Engineer and Founder of EPCA, said, “We’ve now got the world’s highest energy density, full battery-electric mining truck … our mining clients here in Australia are ecstatic that this truck is being built and manufactured right here in Western Australia.”

With 5,500 mining trucks currently operating in Australia (and more than 55,000 operating globally), finding buyers for 50-70 trucks per year seems pretty doable. The only question now is whether EPCA – or, more accurately, Xerotech – can get them built.

As we discussed in our special mining episode of Quick Charge, mines are great applications for battery-electric vehicles, and massive electric vehicles like this one from EPCA and similar models from Caterpillar and Liebherr are filling out the market nicely. That said, I think I made these points well enough there to repost the video, below, and argue out the details in the comments. Enjoy!

Trump halts wind projects, including Coastal Virginia Offshore Wind, Dominion stock drops 5%

The Trump administration on Monday halted Coastal Virginia Offshore Wind, the largest project of its kind in the U.S., as well as four other projects off the East Coast in a devastating blow to the wind industry.

Shares of Dominion Energy, the utility developing the project, dropped more than 5% on the news.

The administration also paused leases for Vineyard Wind 1 off Massachusetts, Revolution Wind off Rhode Island, Sunrise Wind off Long Island and New England, and Empire Wind 1 south of Long Island.

Interior Secretary Doug Burgum said the administration paused leases for the projects due to national security concerns identified by the Pentagon.

Shares of Denmark’s Orsted, the developer of the Revolution and Sunrise projects, tumbled 11%. Norway’s Equinor, the developer of Empire Wind 1, was down less than 1%.

Coastal Virginia Offshore Wind is a 176 turbine project project that would provide enough power for more than 600,000 homes, according to Dominion. The project was expected to be complete next year.

Dominion said the massive project is essential for U.S. national security and Virginia’s dramatically growing energy needs. Northern Virginia is the largest hub for data centers in the world. Growing demand from artificial intelligence is contributing to higher electricity prices in the state.

“Stopping CVOW for any length of time will threaten grid reliability for some of the nation’s most important war fighting, AI, and civilian assets,” Dominion said in a statement.

“It will also lead to energy inflation and threaten thousands of jobs,” the utility said.

Virginia Gov. Glenn Youngkin, a Republican, supports the project. Incoming Gov. Abigail Spanberger, a Democrat, won the gubernatorial election in November on a promise to address rising electricity costs in part by expanding renewable energy.

The Interior Department said in a statement that the pause will give the federal government time to “work with leaseholders and state partners to assess the possibility of mitigating the national security risks posed by these projects.”

Interior said the U.S. government found that turbine blades and “highly reflective towers” create radar interference risk.

“The clutter caused by offshore wind projects obscures legitimate moving targets and generates false targets in the vicinity of the wind projects,” Interior said.

President Donald Trump has targeted the U.S. wind industry since his first day in office. Trump on Jan. 20 ordered a halt to all new leases and permits for onshore and offshore wind pending federal review.

Sen. Chuck Schumer, D-N.Y., condemned Trump’s campaign against wind projects as “irrational.” The senate minority leader said Interior’s decision would spike energy bills.

“Trump’s obsession with killing offshore wind projects is unhinged, irrational, and unjustified,” Schumer said in a statement Monday. “At a time of soaring energy costs, this latest decision from DOI is a backwards step that will drive energy bills even higher.” 

Trump’s campaign against the wind industry has run afoul of the courts. Judge Patti Saris of the U.S. District Court for the District of Massachusetts ruled on Dec. 8 that Trump’s order was “arbitrary and capricious and contrary to law.”

E-quipment highlight: Komatsu PC365-11 hybrid excavator

Thanks to a clever, fully electric swing system and “boom up” power assist features, the big PC365-11 hybrid excavator from Komatsu promises better performance and serious fuel savings compared to conventional diesel machines.

Komatsu says its PC365-11 hybrid excavator uses a “boom-up” power assist feature that captures and stores kinetic energy during different operation cycles, then taps into that power to provide an extra energy boost when needed. The result is 15% more productivity and a 20% improvement in fuel efficiency when compared to non-hybrid excavators in ~40 ton class.

“The PC365LC-11 was engineered for excellence in multifunction applications by leveraging its innovative electric powertrain system to boost job site productivity while reducing fuel consumption,” says Matthew Moen, Komatsu’s product manager. “To highlight these performance enhancements, we’re emphasizing the concept of ‘multifunction plus’ as the defining feature of this machine.”

How it works

Komatsu’s hybrid system replaces the conventional hydraulic swing function with a fully electric swing motor that draws power from an ultracapacitor (as opposed to a battery) energy storage unit. As excavator slows or stops swinging, something like a regenerative braking system captures the kinetic energy that would normally be lost as heat and stores it in the capacitor. Once there, the stored energy can be quickly released to power the swing motor or assist the engine, delivering up to an extra 70 hp when needed to support heavy lifting or digging cycles.

And, thanks to Komatsu’s proprietary software, all of this energy capture and reuse happens automagically during normal work, without the need for external charging. The fuel savings happen because removing the hydraulic load from the ICE engine allows it to run at an ultra-low idle, while the productivity comes from the greater power and overall speed of the electric operations vs. conventional hydraulics.

Electrek’s Take

Trust me when I tell you that Komatsu didn’t wake up one day and decide to build a capacitor-based hybrid crane. One of their customers had the idea and came to them, promising orders. That’s what Komatsu does – from undersea remote control dozers to lunar mining rigs (above), if you bring Komatsu an order, they will absolutely find a way to fill it.

As for PC365-11 hybrid excavator, it’s packed with clever tech, overall – offering significant fuel, emissions, and TCO reductions without dramatically changing the operational logistics of an existing fleet’s operations. That’s all the sales pitch it needs.

Five for Five: Kia PV5 scores 5 star European safety rating

For serious fleet buyers, safety isn’t a “nice-to-have,” it’s an absolute must – and Kia’s new PV5 electric van meets that need with a positively stellar, five-star safety rating on the tough European NCAP safety test.

The new “do-it-all” Kia PV5 showed strong performance across a number of key safety categories, including Occupant Protection, Safety Assist/Crash Avoidance, and Post-Crash Safety. The PV5’s robust suite of standard ADAS technologies that includes AEB, Lane Support System, and Speed Assistance System also helped the new electric work van to deliver top marks in the NCAP’s “real world” test scenarios.

The PV5 opens a new chapter in practical, electrified mobility, offering generous space and modular versatility for everyday use,” explains Sangdae Kim, Executive Vice President and Head of the (relatively) new PBV Business Division at Kia. “Achieving the top Euro NCAP five-star rating is clear validation of its safety performance and will serve as strong momentum as Kia expands its PBV lineup across Europe.”

The Euro NCAP tests highlighted the strong performance of a number of the PV5’s ADAS features, specifically calling out the following:

  • Demonstrated strong responsiveness in vehicle-to-vehicle scenarios
  • Provides additional protection for pedestrians behind the vehicle
  • Avoided collisions in most pedestrian and cyclist test cases

The Kia PV5 slots into familiar territory for US buyers, landing roughly in the same size class as the Ford Transit Connect or Ram ProMaster City, with ~180 cubic feet of interior cargo space available, which is plenty to make it attractive for last-mile delivery and trade work in tight urban markets.

Globally, the PV5 is offered with a number of battery options, including a smaller 43.3 kWh Lithium-Iron-Phosphate (LFP) pack, as well as larger Nickel-Cobalt-Manganese (NCM) packs at 51.5 kWh and 71.2 kWh. The longest-range versions are good for about 250 miles of estimated range – more than enough for Kia to make a case for it as a practical, city-focused alternative to much larger (and pricier) electric vans.

Larger vans, by the way, that may not have that 5 star Euro NCAP rating.
