Strides in Vehicle to Grid Technology Continue

1 October 2025 at 23:23

Vehicle to-grid charging, while still in relatively early phases, is gaining traction across the school bus industry in both the U.S. and Canada.

The promise of V2G technology was frequently discussed in the early days of electric school bus adoption. However, few operations have been successful in giving power back to the grid at levels first promised, with only a handful of projects making headlines.

One such example is from The Mobility House, which announced a “successful implementation” of a V2G charging system at Fremont Unified School District near San Francisco, California. The company has several V2G projects around the U.S., including in New York and Massachusetts, that follow the same scalable approach.

“We were confident in our approach because of our deep experience in implementing V2G projects worldwide, and in school bus fleet electrification here in the U.S.,” said Alex Macharia, VGI program manager at The Mobility House North America. “It was important to establish trust in the technology and in us as an organization from our first conversations with [Director of Transportation Ernest Epley and Fremont]. Ultimately, we found that we were closely aligned on the mission to go beyond electrification by enabling clean reliable transportation that serves the Fremont USD student body while also improving grid resilience to benefit the community.”

Macharia noted that like all V2G projects, the one with Fremont required careful coordination and planning with utility Pacific Gas & Electric (PG&E) to obtain service expansion and interconnection. One of the recurring challenges with V2G, he said, is the functional compatibility between the vehicle, charger and charge management system, or CMS.

The CMS system at Fremont is developed by The Mobility House. According to a press release, ChargePilot manages daily smart charging of the buses, which the fleet operator can view can via an online dashboard. The market aggregation platform receives notifications from PG&E of an upcoming load reduction event via OpenADR, (a communication standard for utilities to provide control commands to distributed energy resources such as batteries and solar inverters) and suggests optimal charging schedules based on the event and time-of-use electricity prices, the release adds.

ChargePilot also adjusts charging optimization for the bus fleet to discharge power to reduce site load during the emergency event, while continuing to ensure vehicle readiness for departure on their next route, noted The Mobility House.

“We have come a long way in developing standardization within the technical interfaces, and this project will be showcasing methods of V2G deployment using open standards, which will resolve some of the complexity,” Macharia said, adding that the Fremont project is currently deployed under the PG&E Emergency Load Reduction Program with insights expected toward the end of next year.

By then, The Mobility House expects to have a full season of ELRP data.

“Program participants are compensated based on how much energy (kWh) or demand (kW) is reduced as compared to a baseline,” he continued, explaining that other partners included the World Resources Institute, Center for Transportation and the Environment, and Polara. “Thirty to 60 hours of events will be called per season (May to October). Events are one to five hours long called between 4 p.m. and 9 p.m.”

Fremont remains in the first phase of the project, with phase two expected to come online this fall. That phase will include the use of six bidirectional chargers.

“As more bidirectional vehicles and chargers come to market, and more utilities begin to offer V2G programs in their territories, The Mobility House will be at the forefront of deploying commercial and residential V2G solutions,” Macharia said.

Meanwhile, Fremont’s Epley said the decision to move toward V2G was driven by both sustainability goals and operational efficiency.

“We wanted to do more than just adopt electric buses. We wanted to maximize their value,” he said. “V2G technology allows us not only to reduce emissions and provide students with a cleaner ride, but also to turn our fleet into a flexible energy resource for the community. That dual purpose, educational and environmental impact paired with fiscal responsibility, was central to our choice.”

He noted that he is not an engineer or utility expert and is instead a “bus driver in a suit who happens to now lead transportation.” Because a project of this size is outside of his area of expertise, Epley said it is important to lean on partners such as PG&E and The Mobility House.

The companies, he added, handled the complex utility upgrades and charger integration, while he was able to continue to focus on daily operations.

“It was about mutual trust. They respected our school mission, and I trusted their technical know-how,” he said. “That’s how we made sure the infrastructure rollout matched our existing buses.

Epley said there were many practical and technical questions to answer. Among them, how would V2G impact battery life? What does the interconnection process look like with the utility? What are the financial models for energy export and savings?

“The Mobility House brought expertise in energy management, while PG&E provided clarity on grid requirements and tariffs. Together, they demystified the process and gave us the confidence to move forward, knowing the technology was both viable and beneficial long-term,” he added.

It’s too early to track financial outcomes, he said, but by discharging energy back to the grid during peak demand periods and charging during off-peak times, Fremont projects a reduction of net charging costs.

“Just as important, the technology is helping us flatten our energy demand curve, which benefits both the district and the grid,” Epley said, adding that the district’s vision is to scale in a deliberate and sustainable way.

The next two electric school buses and additional chargers are scheduled for 2026.

“Even as funding landscapes shift, we’re positioning [Fremont] to demonstrate that electric school buses are not just a pilot project, but a long-term operational norm,” he said. “The integration aligns with our district’s sustainability plan: reducing greenhouse gas emissions, lowering operating costs and setting an example for students on how innovation and responsibility can go hand in hand.”

Epley shared the response from the community and parents has been overwhelmingly positive, with parents appreciating that their children are riding in buses that are cleaner, quieter and healthier for the community.

“Neighbors see us contributing to local grid stability rather than just drawing power” he said. “And students themselves are excited to see their school district at the forefront of clean technology. It becomes a teaching moment. That community support reinforces that we’re not just upgrading buses, we’re helping shape a more sustainable future for Fremont, California.”

Elsewhere, Tucson Electric Power is launching a V2G project this fall. And Fuse Power launched the first V2G electric school bus project in Canada. “Fuse is supplying power back to the grid during peak hours from parked electric trucks and buses. This milestone marks a major step forward in the future of vehicle-to-grid innovation,” according to a company Linkedin post.

California Doubles Down on Zero-Emission Vehicles with Renewed Affordability, Adoption Priorities

By: Ryan Gray
25 August 2025 at 07:00

A new report reaffirms California’s commitment to zero-emission vehicle adoption and deployment despite attempts by Congress and the Trump administration to remove federal waivers that provide the state authority to cut pollution levels within its borders and elsewhere.

The state currently is involved in multiple lawsuits challenging the administration’s efforts to revoke the waivers approved by the Biden administration’s Environmental Protection Agency and others.

The California Air Resources Board (CARB) released the report last week in response to Gov. Gavin  Executive Order N-27-25 in June that directs CARB and several other state agencies to recommend strategies that make clean transportation more affordable, reliable and accessible. ​The report outlines strategies to expand the adoption of Zero-Emission Vehicles (ZEVs) across all vehicle types, including school buses, as part of the state’s broader effort to combat air pollution and climate change. ​

The report highlights California’s leadership in clean transportation, noting that the state has already surpassed its goal of deploying 2 million ZEVs. ​With 56 ZEV manufacturers operating in the state and nearly 178,000 public or shared private electric vehicle chargers installed, California is setting the pace for the nation. ​

However, the CARB report notes that five of the 10 most polluted cities in the U.S. are in California, and millions of residents still live in areas with dangerously high ozone levels, especially in the Los Angeles area and the San Joaquin Valley. ​

To address these challenges, CARB recommends actions across six key areas: Private investment, incentives, infrastructure, fuel pricing, regulations, and procurement. CARB seeks to sustain the Low Carbon Fuel Standard (LCFS) program that utilizes credits from 200 participating companies and from utilities to subsidize clean fuels like renewable diesel and to continue taking advantage of other existing funding programs. It recommends backfilling the federal clean air vehicle tax credits that are set to expire at the end of next month and providing “reliable and consistent funding” to the agency and the California Energy Commission for ZEV deployment and infrastructure incentive programs.

Noting that infrastructure remains one of the largest barriers to ZEV adoption, the report highlights the need for increased reliability of and access to EV chargers, including timely repair. CARB also recommends streamlining permitting processes and utility energization timelines. This includes implementing flexible service connections and other strategies to eliminate delays in EV charging installation.

CARB also calls for unlocking the benefits of V2G by improving the energization process to enable vehicles to power homes and businesses or to export power to the grid during peak demand periods. This includes developing utility rates “that align EV charging and discharging with grid needs” and establishing incentives to automakers that build EVs that can provide backup power. CARB also writes that standards are needed for chargers to enable the use of vehicle-grid integration.

School buses are directly impacted by the state’s push for ZEV adoption. The report emphasizes the need for incentives and infrastructure to support the transition to zero-emission buses. ​For school districts, this could mean additional access to funding programs that make it easier to replace aging diesel buses with electric or even hydrogen-powered alternatives. ​Additionally, CARB says the focus on building reliable charging infrastructure could alleviate concerns about fueling capacity and range limitations. ​

For companies operating school buses, the report’s recommendations present both opportunities and challenges. The emphasis on private investment through programs like the LCFS could provide financial incentives for operators to transition their fleets. ​Additionally, the state’s focus on workforce development could help create a pipeline of skilled workers to maintain and operate ZEVs. ​

However, the transition will require careful planning. CARB states operators will need to navigate new regulations, invest in charging or fueling infrastructure and ensure their fleets meet the state’s reliability and durability standards. Collaboration with state agencies and local governments will be key to overcoming these hurdles.

The CARB report also notes 17 other states and the District of Columbia have chosen to adopt at least part of California’s vehicle standards. The demand in these states for clean transportation collectively represents 40 percent of the nation’s new light-duty vehicle market and 25 percent of the nation’s new heavy-duty vehicle market, which are three to four times that of California alone. In addition, three of these states have established complementary regulations similar to California’s LCFS to further advance the clean vehicle market.

STN EXPO West and Uncharted Territory

7 August 2025 at 22:48

I loved the Green Bus Summit at STN EXPO West in Reno, Nevada. Of course I did. I’m an extrovert, an electric school bus (ESB) nerd ever hungry to learn new things, and I grew up in a desert. This was my sixth STN EXPO conference, and the third I’ve covered for STN as a writer specializing in ESB related topics.

That said, some things not discussed at the Green Bus Summit, at least not officially, are as pressing as the topics that are more popular and comfortable. I’ll get to those in a minute. On the lighter side, part of covering a conference is just listening in general (some might call this eavesdropping). I overheard at the opening reception: “Right, we are not pro-electric, we’re sitting back and letting everybody else work through all the problems before we do anything.”

I get it. If I was already working hard and wouldn’t be paid extra for taking the risks of the ESB path, maybe I’d stay with the status quo of fossil-fueled buses, too. The people running ESBs, though, look as wide-awake, alive and happy as anyone I’ve ever met. And John Wyskiel, president and CEO of Blue Bird, stated that students who ride ESBs arrive at school calmer and more ready to learn.

Technology in general, STN Chief Content Officer Ryan Gray noted, is an increasing theme for the school bus industry. New technology always carries risk. Henry Ford had failures. Diesel was once new and iffy. I liked STN President Tony Corpin’s story of when his parents, Bill and Colette Paul, were starting the magazine up in 1991. Its success was not assured. Blue Bird (and others) gave them a check, a year’s advertising in advance, for the fledgling publication. Their investment implied, “We trust you.” The magazine flourished.

In contrast, the districts that trusted and invested in Lion Electric regret it.

(A few days and after I returned home from Reno, a colleague forwarded me the letter that the newly purchased Lion sent out U.S. owners of Lion Electric school buses. It states their warranties are now void. ESB advocacy groups CALSTART, the Alliance for Electric School Buses and World Resources Institute are working to support Lion owners.)

We heard a lot about Artificial Intelligence (AI) growing rapidly in the school bus world, but little mention of its enormous use of electricity and water. That’s problematic in that power outages and prolonged droughts are on the rise, especially in the West (we were sitting in a Western desert). Should we automatically use AI without limits? Or do we choose how to use it? And do we see ESBs as not just using electricity, but also being able to feed energy back into the grid (V2G), or, more locally and with simpler technology, into a school building during a power outage (V2B)?

First-time STN EXPO attendee Clarissa Castrowore native Navajo dress at the trade show (we were told to dress up). She drives long rural routes for Window Rock Unified School District in Arizona. Window Rock is the capital of the Navajo Nation’s reservation. Castro said, “I like the conference a lot! We have too many-stop arm violations. We need to update our technology.”

For the record, I do not think ESBs are for everybody. For example, I don’t think Window Rock Unified School District in Arizona should pursue them. About 30 percent of residences on the Navajo reservation don’t have electricity yet. I’d think addressing that is a top priority. Literacy rates go up when homes gain electricity (being an ESB nerd makes you an energy nerd, as well).

Jessica Sevilla, director of fleet and facilities at Antelope Valley Schools Transportation Agency in Southern California, runs 230 school buses, 41 of them electric. “The leap between the worlds [from fossil-fueled to electric] is larger than we’d thought. Mechanics are learning to reach for laptops instead of wrenches.”

She emphasized training and said employee openness to ESBs depended partly on “where they’re at in their careers.” In other words, those earlier in their careers may be more open to learning new skills. Other panelists agreed that ESB driving skill has an enormous impact on range. A feather-foot that maximizes regenerative braking can add dozens of miles of range over the course of a day.

Charles Kriete, CEO of Zonar, told us our business is access to education, not necessarily transportation. I’d call that a paradigm shift. In keeping with Kriete’s declaration, Billy Huish, from rural Farmington Municipal Schools in New Mexico, told me he created an extended classroom by providing 71,000 hours of Wi-Fi, so far, to students on his 68 buses.

“What about TikTok?” I asked anxiously. Absolutely blocked, he assured me.

Speaking of anxiety, Kriete said parent calls are reduced by 50 percent when they can use an app to see where their child is. I’ve never fielded a concerned parent’s call, but I can imagine the urgency of resolving where the child is, the rising intensity if it takes too long, and both parents’ and dispatchers’ desires to have fewer such calls.

But even if a school district can afford the best ridership verification technology (many can’t), quota-driven ICE raids, with schools and school bus stops no longer protected from them, may lead to children going missing, or maybe more likely, their parents being abruptly swept away, unable to pick up their children. That’s a harrowing thought, especially with due process going missing, in general. Stay with me.

Transportation directors had plenty to say on this topic, on condition of anonymity, that is. One knew of children dropping out of school and afraid to leave the house after relatives were abruptly deported. The families stay quiet because they don’t want to be targeted. Another has children no longer riding the school bus because parents are fearful of ICE.

They still attend school, if their parents can drive them (not all can).

One transportation director, whose district’s policy is for employees to not surrender children to ICE agents, told me his district’s attorneys were unable to answer the following question he posed to them: “Are you making it a job requirement of my bus drivers to defy ICE agents and risk being taken away, themselves? Because some of them have kids at home who’re depending on them.”

I looked steadily, uncomfortably, into my colleague’s eyes. “We’re in uncharted territory,” he told me.

I found that staff with ESBs can be all over the map on how engaged they are with them. One transportation director had received his first two ESBs, but no idea whether he had Level 2 or Level 3 charging. Tracking your charging saves much money, as noted by Bobby Stafford, Anthony Ashley and Craig Beaver in the session, “What You Need To Know About Working With Your Utility.”

Beaver, administrator of transportation at Beaverton School District near Portland, Oregon, was STN’s Transportation Director of the Year in 2024. He reported that when he moved his ESBs from peak charging to off-peak charging, his monthly electricity bills went from $50,000 to $60,000 per month to $30,000 per month.

He advocated for vehicle to building (V2B) as opposed to vehicle to grid (V2G). He cited MOVER (Microgrid Opportunities: Vehicles Enhancing Resiliency) project (disclosure: I am among the partners in this project) in Hood River, Oregon. Beaver sees V2G as needing more time to develop. The most successful V2G program is run by Zum for Oakland Unified School District in California. Zum reports 75 ESBs are discharging 2.1 gigawatts back into the Pacific Gas and Electric grid annually, enough to power 300 homes for a year.

In contrast to the Zum V2G project, V2B projects would be under local control. Beaver is building a microgrid with Portland General Electric, his utility, that he reported has been excellent to work with. Ashley, the director of fleet for Atlanta Public Schools, reported a “less flowery experience” with Georgia Electric He advised his peers to do their research before signing a contract with their utility.

Beaver floated the idea of a Fire Relief Center for his microgrid, fueled in part by his ESBs. Heat is by far the most fatal form of extreme weather, and children are more vulnerable to extreme heat than adults. My Tedx talk on ESBs dramatizes a heat-dome scenario in which ESBs discharge energy into a community resilience center, cooling people in an outage, potentially saving lives.

Reno itself was just named the fastest warming city in the U.S. for the second year in a row. Were you out there, sweating along with me at the Ride and Drive? Can you imagine the air conditioning at the Reno conference failing for even a day? I suggest we start to imagine it. Power outages are growing nationwide as temperatures keep rising, energy loads keep growing, and the aging electric grid falters.

I do not sell ESBs or push them on anyone. I think keeping kids in school, safely learning and growing, is our core mission. I do suggest that accessing the motherlode of energy housed in our nation’s 5,000 electric school buses is a good additional mission, in our increasingly hot, anxious, energy-hungry country.


Alison Wiley is a transportation electrification professional who helps bus fleets make the transition from diesel to electric. She produces the the Electric School Bus Newsletter and gave a TedTalk last year that advocates for the use of electric school buses as a tool of equity and inclusion. She is based in Portland, Oregon.
