Picking up Inspiration at STN Expo West
Four Themes Shaping the Future of Electric School Transportation

Every year, STN Expo West brings together school transportation professionals, fleet operators, manufacturers, technology providers, and policymakers to discuss industry trends, training opportunities, products, and services. It’s a diverse group of participants exploring a wide array of topics but organized around a common goal: safely transporting students while preparing for the future of mobility.

Across the exhibit hall and in conversations among industry leaders, electric school buses remain a hot topic, but no longer as a future concept. Walking the show floor, it was clear that in 2026, electric school buses are an integral part of modern school transportation. Questions about their viability and range have given way to discussions about charging infrastructure, grid integration, procurement strategies, and the partnerships needed to successfully deploy zero-emission fleets at scale. Electric has already arrived; now, it’s ready to go even further.

CALSTART attended the conference through a program it administers, Cal Fleet Advisor, which provides California school bus fleets with no-cost technical guidance as they navigate the transition to zero-emission transportation. Conversations throughout the week reinforced many of the trends our team is seeing across the industry, while providing plenty of new context and insight along the way.

In short, STN Expo West offered an important snapshot of where school transportation stands today; but perhaps more importantly, it pointed attendees in the direction of where this ever-evolving industry is headed next.

Let’s talk about four themes that stood out to us, and why they matter.

From proving the technology to powering the grid

The conversation around electric school buses has changed dramatically over the last several years. Instead of asking whether electric school buses are viable, fleets are increasingly asking how they can deploy them more effectively. Vehicle technology continues to mature, manufacturers are refining vehicle systems, and operational experience is helping fleets better understand everything from charging needs to route planning.

During conversations with manufacturers including RIDE, CALSTART heard continued optimism about the electric school bus market. Rising fuel costs continue to strengthen the long-term value proposition for zero-emission buses, while advances in battery technology are helping address concerns around range and performance.

Vehicle-to-grid technology also remains a growing area of interest. One conference panel explored how electric school buses can serve not only as transportation assets but also as distributed energy resources, returning electricity to the grid during periods of peak demand. As adoption grows, larger fleets could create meaningful benefits for the school districts, utilities, and communities surrounding them. It’s particularly exciting that electric school buses are now a part of larger conversations about energy resilience.

The next breakthrough may not be in how buses are built, but in how they’re bought.

Affordability remains one of the biggest challenges facing school districts, and organizations across the industry are exploring innovative procurement models designed to reduce costs through collaboration. One emerging strategy is aggregated procurement, or bringing together multiple buyers into a coordinated purchasing effort to create larger, more predictable demand for manufacturers. Greater purchasing volume can help streamline transactions, improve production planning, and ultimately lower vehicle prices.

The concept is already gaining traction in transportation sectors. The World Resources Institute, in partnership with TRC, is developing a blueprint for aggregated electric school bus procurement informed by a series of stakeholder interviews. The aggregated procurement blueprint will prioritize scale, flexibility, and accessibility while preserving sufficient regional and operational customization. The intent is to not only identify the best mechanism for lowering vehicle prices but also reduce transaction costs, simplify implementation, and address infrastructure barriers while ensuring participation among smaller and under-resourced districts.

Charging infrastructure is becoming smarter.

Vehicle-to-grid discussions received considerable attention at STN Expo West, but another important infrastructure trend is beginning to emerge: flexible interconnection. For many fleets, the biggest obstacle to adoption is adding the electrical capacity required to charge these buses. Traditional utility upgrades can sometimes take months or even years before new charging infrastructure can be fully connected to the grid.

Flexible interconnection offers another path. Rather than requiring immediate grid expansion, flexible interconnection uses managed charging software to temporarily limit charging loads, allowing fleets to begin operating while utilities complete long-term infrastructure improvements. In other words, fleets can start charging sooner instead of waiting for permanent upgrades.

Utilities and technology providers are already piloting this approach. The northeast U.S. utility National Grid is exploring active resource integration, a form of dynamic grid management that allows distributed energy resources to connect more efficiently while maintaining grid reliability. Similarly, Pacific Gas & Electric’s Flex Connect Pilot Program enables customers to connect charging infrastructure more quickly by managing electrical demand before physical upgrades are completed.

As electric school bus adoption grows, innovations like flexible interconnection could prove just as important as advances in batteries or charging equipment. Smarter infrastructure planning can shorten deployment timelines, reduce costs, and help school districts put zero-emission buses into service faster.

Mobile charging is expanding what’s possible.

Another emerging trend gaining attention across commercial transportation is mobile charging. Instead of relying exclusively on permanent charging installations, fleets are beginning to explore portable charging systems that provide greater operational flexibility. For school districts, this technology can help address a number of common challenges, including delays when waiting for utility upgrades. In these scenarios, mobile charging can provide a bridge solution that allows vehicles to begin operating before permanent infrastructure is complete.

For districts still evaluating depot layouts or long-term charging strategies, portable chargers offer the flexibility to test different configurations before making significant infrastructure investments. And when paired with battery storage or solar generation, mobile charging systems can help fleets manage electricity costs while reducing reliance on peak-demand periods.

Not all mobile charging solutions are emissions-free, however. Some systems generate electricity onsite using diesel or other fossil fuels, while newer approaches rely on stored grid electricity or renewable energy to deliver zero-emission charging.

Several companies are already demonstrating emissions-free solutions. CALSTART member Orange EV recently introduced the Juicer, a mobile charging solution that stores energy from existing electrical infrastructure before delivering high-power DC charging when vehicles need it. Although not currently deployed for electric school buses, applications like this illustrate how mobile energy storage could expand charging options across many fleet applications.

Other manufacturers like Xos are advancing mobile charging technologies while making plans for some high-profile upcoming demonstrations. Xos recently highlighted the potential role of mobile battery systems in supporting transportation during the 2028 Los Angeles Olympic Games, where demand for electric school buses has grown as part of the event’s sustainability plans, with 500 expected to be deployed to provide rides for the Games. Xos noted that temporary charging infrastructure could help serve transit buses, school buses, and other electric fleets where permanent charging installations may not be feasible.

As charging technology evolves, mobility itself is becoming part of the charging solution.

What’s next?

STN Expo West remains one of the industry’s premier opportunities to connect with the people shaping the future of student transportation. This year’s event highlighted meaningful progress, but it also underscored an important reality: The transition to zero-emission school transportation extends far beyond vehicle technology. Procurement innovation, smarter infrastructure planning, grid integration, and flexible charging solutions will all play critical roles in helping school districts successfully electrify their fleets. At CALSTART, we’re committed to helping fleets understand this big picture, and what that picture will look like in the years to come. Through programs, research, technical expertise, and collaboration with industry leaders, we continue working to accelerate the transition to clean transportation while equipping fleets with the information and resources they need to make confident decisions.
