As deadly wildfires have destroyed communities from California to Maui, the nation’s largest utility, Pacific Gas and Electric, is making headway on its ambitious goal to move 10,000 miles of power lines in fire-prone areas underground, which would greatly reduce ignition risk.

“We’re coming off of a historic drought and those conditions are materially different than the conditions that we saw just 10 short years ago. And so now is absolutely the right time to be taking bold, decisive action with regard to the grid safety,” said Jamie Martin, PG&E’s vice president of undergrounding.

Five years ago, PG&E’s equipment sparked the deadly Camp Fire, which destroyed the town of Paradise, California, and killed 85 people. The massive liabilities drove the utility into bankruptcy, from which it emerged in 2020. But just a year later, in the same county, PG&E’s equipment started another catastrophic fire, prompting the utility to announce its extensive undergrounding plan. The utility has undergrounded 350 miles of power lines so far this year, and more than 600 miles since 2021.

While Martin says moving power lines underground reduces ignition risk by 98%, it comes at a steep cost. Data compiled by the California Public Utilities Commission shows that undergrounding just one mile costs anywhere between $1.85 million and $6.1 million, meaning PG&E’s total plan would likely be in the tens of billions. The bill would be footed by PG&E’s customers, who already face some of the highest rates in the nation.

“If we keep pushing up electricity rates, the most vulnerable of us are not going to be able to pay,” says Katy Morsony, a staff attorney with The Utility Reform Network, a consumer advocacy group that supports a more limited approach to undergrounding.

Since PG&E earns a guaranteed rate of return on capital investments, the utility is inherently incentivized to undertake more expensive infrastructure projects such as undergrounding, explained Morsony and Daniel Kirschen, a professor of power and energy systems at the University of Washington. This is how the utility makes money, not by selling electricity or gas.

“Undergrounding […] costs a lot of money. It’s a large investment. So that would increase the revenue that the utilities collect,” Kirschen explains. “Now, the question is would these other solutions be as effective as those big investment projects? That’s where the regulators have to step in.”

PG&E said in a statement that, “In the case of undergrounding, our investors’ priorities are aligned with those of our customers and our safety regulators.”

‘Essentially eliminating the risk of ignition’

PG&E currently has about 27,000 miles of power lines underground, but these are generally not in areas of high wildfire risk. So during storms, when high winds could cause a line to topple over or a tree to fall onto a line, utilities have few good options.

“So one option is to essentially just shut down the power line, because if there is no voltage and no current on the line, there is no chance of this release of energy happening and then there is no chance of an ignition,” explains Line Roald, an associate professor at the University of Wisconsin-Madison whose work includes modeling the risk of wildfire ignition and power outages in the electric grid.

Indeed, PG&E has been implementing Public Safety Power Shutoffs in California since 2019, affecting millions of people. Hawaiian Electric, the utility that could be found liable for the Maui wildfires that killed at least 98 people, has been criticized for not shutting off power in advance of high wind warnings. If the company is determined to be at fault, it doesn’t have nearly enough money to pay off residents’ damage claims. 

Looked at this way, undergrounding is undoubtedly cheaper than dealing with the massive costs of deadly wildfires, and less disruptive than shutting off power completely.

“So for this one-time capital investment, we’re essentially eliminating the risk of ignition from an overhead power line by placing it underground,” Martin says.

PG&E isn’t the only utility that’s interested. San Diego Gas & Electric has a plan to underground about 1,450 miles of power lines through 2031, while Florida Power and Light is undergrounding select lines for hurricane protection. Austin Energy is also exploring undergrounding in the wake of a winter ice storm that caused weeks-long outages, and the federal government has pledged to provide $95 million to Maui to harden its electric grid, work that could include undergrounding lines.

The price of safety

Construction workers in Arnold, California use a piece of equipment called a rock wheel to dig a trench, so that PG&E can move its power lines underground.

But the CPUC has since released two cheaper, alternate proposals for consideration, which greatly cut back on undergrounding. One calls for moving just 200 miles underground and insulating 1,800 miles with covered conductors through 2026, while the other involves undergrounding 973 miles and insulating 1,027 miles.

Both proposals would save money but would ultimately put PG&E’s 10,000 mile goal in jeopardy. Plus, PG&E says that insulating lines is only about 65% effective at reducing wildfire risk, far less effective than undergrounding.

“If a tree falls on a line, the line is going to break and you’re still going to have a risk of a spark and you still have a chance of starting a wildfire, even if the line is insulated,” explains Kirschen.

The Utility Reform Network supports the plan to underground 200 miles, and estimates the cost of insulation to be about $800,000 per mile, as compared with the $3.3 million per mile that PG&E spent on undergrounding in 2022.

“By relying more heavily on insulated lines, we can do the work faster and we can deliver that wildfire safety more quickly to those different communities,” Morsony says.

Come November, the CPUC will decide on a path forward for PG&E, with both wildfire risk and customers’ utility bills hanging in the balance.

JB Hunt launches first electric aftermarket semi truck route in Arizona

Following successful inbound implementations in the Pacific Northwest, North Carolina, and Mexico, Daimler Trucks North America (DTNA) is expanding the reach of its electric semi fleet into Arizona with long-time associate JB Hunt.

JB Hunt will add the new Freightliner eCascadia electric semi to its Arizona fleet immediately, and put it to work delivering aftermarket truck parts from DTNA’s parts distribution center (PDC) in Phoenix to multiple DTNA dealers along a dedicated route.

The electric Freightliner truck is expected to cover approximately 100 miles in a given day before heading “home” to a Detroit eFill charger installed at Daimler’s Phoenix facility.

This milestone marks the first all-electric route in the DTNA aftermarket parts distribution network, significantly reducing carbon emissions and setting a precedent for future sustainable outbound logistics operations.

“This solution with DTNA is a great example of our commitment to supporting customers’ efforts to reduce their carbon footprint and work towards energy transition,” explains Greer Woodruff, executive vice president of safety, sustainability and maintenance at JB Hunt. “JB Hunt owns and operates several eCascadias on behalf of customers, and our drivers have really enjoyed their in-cab experience. As customer interest continues to grow, we are here to enable their pursuit for a more sustainable supply chain in the most economic means possible.”

Daimler is analyzing future expansion opportunities throughout its internal parts distribution and logistics with an eye on electrifing additional routes and further reducing the carbon footprint of its logistics operations.

JB Hunt will evaluate its utilization of the charging station for other customers in the area, eventually enabling fully integrated zero-emission vehicle solutions into its 3PL fleets.

Mitsubishi Fuso cleans up, putting 89 electric garbage trucks to work in Greece

Mitsubishi Fuso cleans up, putting 89 electric garbage trucks to work in Greece

The Greek cities of Athens and Thessaloniki are popular tourist spots, and those tourists are about to breathe a little bit easier – literally! – thanks to nearly 90 new electric garbage trucks from Mitsubishi Fuso.

The Daimler-owned Mitsubishi Fuso brand has been making big moves since export of its newest electric eCanter medium duty truck kicked off earlier this year. First expanding to Hong Kong, and now taking orders in the EU.

“Thanks to its compact dimensions and high chassis load capacity, the electric Next Generation eCanter is ideal for waste disposal companies that drive on narrow roads,” says Florian Schulz, Head of Sales, Marketing and Customer Services. “In addition, the vehicle is locally emission-free and quiet, so that garbage can be emptied early in the morning in densely populated areas. This makes it particularly suitable for municipal applications.”

One of the most important goals the cities’ governments had was to quiet down the garbage collection process. To that end, Greek body manufacturer KAOUSSIS has put a lot of development work into the upfit body to quiet the hydraulic and compaction actions. The company is calling its refuse body “the first of its kind,” creating a market advantage for the electric eCanter while meeting all EU technical regulations for operating waste disposal vehicles with standing personnel.

The hydraulic system employs proportional, electro-hydraulically operated directional valves that operate at a maximum pressure of 180 bar. KAOUSSIS says it’s specially designed for EVs, and is compatible with garbage bins between 80 and 390 liter (aka: really big) capacities. The lift also features a dynamic weighing system that records the weight of the waste with an accuracy of up to ±0.5 kg (about a pound).

“We have had a very close cooperation with KAOUSSIS for over 30 years,” says Antonios Evangeloulis, Director of Sales & Marketing of the Greek importer & general agent for Daimler truck products and services Star Automotive Hellas. “All the necessary tools, safety measures, technicians, training and certifications are in place and we are able to offer excellent after-sales support for these vehicles. Overall, it was an exciting project that we were able to realize together.”

Forty of the new electric refuse trucks are expected to be deployed by the end of November, with the balance expected to be delivered over the course of 2025.

Electrek’s Take

Electrifying the commercial truck fleet is a key part of decarbonizing city truck fleets – not just here in the US, but around the world. I called the eCanter, “a great product for moving stuff around densely packed city streets,” and garbage is definitely “stuff.”

Here’s hoping we see more “right size” electric solutions like this one in small towns and tight urban environments stateside somewhat sooner than later.

Italian DC fast charger maker Alpitronic enters the US market [video]

Electrek‘s Seth Weintraub went to Alpitronic America’s new HQ to speak with CEO Mike Doucleff about its plans to roll out its ultra-fast chargers across the US.

Bolzano, Italy-based Alpitronic was founded in 2009, and it specializes in the development and production of DC fast chargers. The global company’s best-known product line is the Hypercharger, an ultra-fast EV charging station that can deliver charging power from 50 kW to 400 kW, depending on the model.

Alpitronic Americas recently announced an agreement with Mercedes-Benz High-Power Charging to become the first DC fast-charging network to deploy Hypercharger 400 units at scale in the US.

Alpitronics Americas’ new headquarters’ 68,000-square-foot office and industrial space in Charlotte, North Carolina, includes a diagnostics laboratory and repair center, a spare parts warehouse, a training center, and space for as many as 300 employees.

The Bolzano, Italy-based company’s Hyperchargers achieve, on average, an efficiency rate greater than 97.5%, and that its repair and service network can service chargers anywhere in the US.

Alpitronic cofounder and CEO Philipp Senoner said, “As a natural part of Alpitronic’s growth, we are anxious to expand our industry-leading Hypercharger network from Europe, where we are market-share leader, to North America. We are pleased with the talent we are finding in North Carolina and look forward to setting a new standard for the EV charging network in the US.”

Alpitronic chargers support all EV brands. Pre-production units have been tested publicly in Rock Hill, SC, and Portland, OR. The first US-built, public chargers are expected to be installed and available in October.

Seth and Mike Doucleff discuss what Aliptronic’s main driver was to come to the US, what attracted them to Charlotte, and what the company thinks the future of DC fast chargers is in the US, among other things. Their conversation begins at 00:41 on the Electrek podcast below:
