Bidirectional charging allows EV owners to use energy from their car batteries to power their homes or send the energy back to the grid. The innovative technology can save EV drivers money on utility costs while helping lower electricity demand during peak periods.
How bidirectional EV charging can bring down utility costs
EV drivers are quickly learning their cars are good for more than just zero-emission driving. Electric vehicles utilize powerful, compact batteries that can charge and discharge quickly and efficiently.
The ability to send energy back and forth from the vehicle to the grid (V2G) and vice versa is a significant benefit of owning an EV. If deployed properly, it can save utility customers money while protecting the US’s aging grid infrastructure.
Companies like PG&E and Duke Energy are launching programs aimed at studying the best ways to utilize this technology.
Duke Energy partnered with Ford F-150 Lightning owners in August to use the EV pickup’s powerful battery to supply energy during peak hours, lowering grid intensity and savings across the network.
PG&E is initiating a program of its own to test bidirectional EV charging for homes, for businesses, and with local microgrids.
PG&E launches V2X pilot to test EVs as mobile batteries
Pacific Gas and Electric Company (PG&E) is rolling out three new Vehicle-to-Everything (V2X) pilot programs to determine the best practices to maximize bidirectional EV charging benefits for consumers and the grid.
In a press release Tuesday, PG&E invited customers to participate in a pre-enrollment for its new V2X program.
The plan involves allowing EV drivers to utilize their vehicle’s battery, leveraging it to earn money and offset energy use when demand is the highest. Participation involves:
Powering your property temporarily when there’s an outage.
Charging your vehicle during times with less demand while using the EVs power when energy during peak hours (4 p.m. to 9 p.m.).
Earning additional revenue incentives from sending energy back to the grid during high-demand periods.
Users will earn an upfront payment and performance-based incentives for participating in the V2X program. Enrollment in PG&E’s Emergency Load Reduction Program can provide additional savings, which can help offset the costs of buying and installing a bidirectional EV charger.
The incentives include:
V2X Residential
Up to $2,500 upfront ($3,000 for customers in disadvantaged communities).
Up to $2,175 additional for providing stored energy to the grid in times of high demand through auto-enrollment in the ELRP demand response program.
V2X Commercial
Up to $2,500 upfront ($3,000 for customers in disadvantaged communities) for installing a three-phase bidirectional charger less than 50 kW.
Up to $3,625 additional for providing stored energy to the grid in times of high demand through auto-enrollment in the ELRP demand response program.
Up to $4,500 upfront ($5,000 for customers in disadvantaged communities) for installing a three-phase bidirectional charger greater than or equal to 50 kW.
Up to $3,625 additional for providing stored energy to the grid in times of high demand through auto-enrollment in the ELRP demand response program.
V2X Microgrids
Up to $3,750 for providing stored energy to the grid in times of high demand through auto-enrollment in the ELRP demand response program.
Can stack incentives with V2X Residential or Commercial
Currently, the only EV to qualify is the Ford F-150 Lightning. However, EVs based on the Hyundai Motor Group’s E-GMP platform, including the Hyundai IONIQ5, Kia EV6, and Genesis GV60, are expected to be eligible between 2023 to 2024, followed by VW ID.4 (2023-2024), Porsche Taycan (2024), GM Silverado (2024), Volvo EX90 (2024-2025), and Polestar 3 (2025).
Electrek’s Take
Bidirectional charging can play a critical role in transitioning to a green energy economy. The rising frequency of extreme weather events is testing the aging US grid infrastructure, simultaneously increasing energy demand while limiting the ability to generate it.
One way to solve this is by implementing widespread renewable energy like wind and solar, but this will take time to deploy.
In the meantime, electric vehicles can play an integral role. EVs with bidirectional charging capabilities can help reduce stress on the grid during peak demand hours while saving on utility costs.

Last week, Parker Hannifin launched what they’re calling the industry’s first certified Mobile Electrification Technology Center to train mobile equipment technicians make the transition from conventional diesel engines to modern electric motors.
The electrification of mobile equipment is opening new doors for construction and engineering companies working in indoor, environmentally sensitive, or noise-regulated urban environments – but it also poses a new set of challenges that, while they mirror some of the challenges internal combustion faced a century ago, aren’t yet fully solved. These go beyond just getting energy to the equipment assets’ batteries, and include the integration of hydraulic implements, electronic controls, and the myriad of upfit accessories that have been developed over the last five decades to operate on 12V power.
At the same time, manufacturers and dealers have to ensure the safety of their technicians, which includes providing comprehensive training on the intricacies of high-voltage electric vehicle repair and maintenance – and that’s where Parker’s new mobile equipment training program comes in, helping to accelerate the shift to EVs.
“We are excited to partner with these outstanding distributors at a higher level. Their commitment to designing innovative mobile electrification systems aligns perfectly with our vision to empower machine manufacturers in reducing their environmental footprint while enhancing operational efficiency,” explains Mark Schoessler, VP of sales for Parker’s Motion Systems Group. “Their expertise in designing mobile electrification systems and their capability to deliver integrated solutions will help to maximize the impact of Parker’s expanding METC network.”

The manufacturing equipment experts at Nott Company were among the first to go through the Parker Hannifin training program, certifying their technicians on Parker’s electric motors, drives, coolers, controllers and control systems.
“We are proud to be recognized for our unwavering dedication to advancing mobile electrification technologies and delivering cutting-edge solutions,” says Nott CEO, Markus Rauchhaus. “This milestone would not have been possible without our incredible partners, customers and the team at Nott Company.”
In addition to Nott, two other North American distributors (Depatie Fluid Power in Portage, Michigan, and Hydradyne in Fort Worth, Texas) have completed the Parker certification.

With the rise of electric equipment assets like Bobcat’s T7X compact track loader and E10e electric excavator that eliminate traditional hydraulics and rely on high-voltage battery systems, specialized electrical systems training is becoming increasingly important. Seasoned, steady hands with decades of diesel and hydraulic systems experience are obsolete, and they’ll need to learn new skills to stay relevant.
Certification programs like Parker’s are working to bridge that skills gap, equipping technicians with the skills to maximize performance while mitigating risks associated with high-voltage systems. Here’s hoping more of these start popping up sooner than later.
Based on a Peterbilt 579 commercial semi truck, the ReVolt EREV hybrid electric semi truck promises 40% better fuel economy and more than twice the torque of a conventional, diesel-powered semi. The concept has promise – and now, it has customers.
Austin, Texas-based ReVolt Motors scored its first win with specialist carrier Page Trucking, who’s rolling the dice on five of the Peterbilt 579-based hybrid big rigs — with another order for 15 more of the modified Petes waiting in the wings if the initial five work out.
The deal will see ReVolt’s “dual-power system” put to the test in real-world conditions, pairing its e-axles’ battery-electric torque with up to 1,200 miles of diesel-extended range.

The ReVolt team starts off with a Peterbilt, then removes the transmission and drive axle, replacing them with a large genhead and batteries. As the big Pete’s diesel engine runs (that’s right, kids – the engine stays in place), it creates electrical energy that’s stored in the trucks’ batteries. Those electrons then flow to the truck’s 670 hp e-axles, putting down a massive, 3500 lb-ft of Earth-moving torque to the ground at 0 rpm.

The result is an electrically-driven semi truck that works like a big BMW i3 or other EREV, and packs enough battery capacity to operate as a ZEV (sorry, ZET) in ports and urban clean zones. And, more importantly, allows over-the-road drivers to hotel for up to 34 hours without idling the engine or requiring a grid connection.
That ability to “hotel” in the cab is incredibly important, especially as the national shortage of semi truck parking continues to worsen and the number of goods shipped across America’s roads continues to increase.
And, because the ReVolt trucks can hotel without the noise and emissions of diesel or the loss of range of pure electric, they can immediately “plug in” to existing long-haul routes without the need to wait for a commercial truck charging infrastructure to materialize.
“Drivers should not have to choose between losing their longtime routes because of changing regulatory environments or losing the truck in which they have already made significant investments,” explains Gus Gardner, ReVolt founder and CEO. “American truckers want their trucks to reflect their identity, and our retrofit technology allows them to continue driving the trucks they love while still making a living.”
If all of that sounds familiar, it’s probably because you’ve heard of Hyliion.
In addition to being located in the same town and employing the same idea in the same Peterbilt 579 tractor, ReVolt even employs some of the same key players as Hyliion: both the company’s CTO, Chandra Patil, and its Director of Engineering, Blake Witchie, previously worked at Hyliion’s truck works.
Still, Hyliion made their choice when they shut down their truck business. ReVolt seems to have picked up the ball – and their first customer is eager to run with it.
“Our industry is undergoing a major transition, and fleet owners need practical solutions that make financial sense while reducing our environmental impact,” said Dan Titus, CEO of Page Trucking. “ReVolt’s hybrid drivetrain lowers our fuel costs, providing our drivers with a powerful and efficient truck, all without the need for expensive charging infrastructure or worrying about state compliance mandates. The reduced emissions also enable our customers to reduce their Scope 2 emissions.”
Page Trucking has a fleet of approximately 500 trucks in service, serving the agriculture, hazardous materials, and bulk commodities industries throughout Texas. And, if ReVolt’s EREV semis live up to their promise, expect them to operate a lot more than 20 of ’em.
Fleet electrification expert Tony Nisam took to LinkedIn yesterday to post a deal that he ran across at a Washington State Costco that stacks a $25,500 manufacturer rebate with $3,000 in “regular” Costco Member Savings, $2,750 in “LIMITED-TIME” Manufacturer to Member Incentives, plus an additional $250 for Costco Executive members.
Do a bit of math (add up 25,500 + 3,000 + $2,750 + 250), and you’ll calculate an almost unheard of $31,500 discount on one of the best, most capable commercial vans on the market – ICE or electric. And that’s before you factor in the 0% interest financing (72 mo.) being advertised at Blade Chevrolet, the Mount Vernon, Washington, where VIN 2G58J2TY6S9104313 (the exact van shown, below) is shown as stock number 16757.
If you’re not a Costco member yet and you’re looking for a new truck for your business or even a unique #vanlife ride with zero emissions, modern tech, and a nationwide dealer network, GM makes that $130 Executive membership seem like a no-brainer.
