RENO, Nev. – The Green Bus Summit at STN EXPO West in July explored how efficiency and modernization are reshaping student transportation. Experts shared practical strategies for using cleaner powertrains, connected technology, operational data and resilient infrastructure to reduce costs, improve reliability and prepare school bus operations for the future.

Cummins

Nicole Wheeldon, general manager of busing for North America at Cummins, joined Chris Karlin, account manager for International Motors; Matthew McGinn, senior director of e-mobility sales for Accelera by Cummins; and Matthew McClure, current product and OEM service manager for Bus North America at Cummins. They discussed how emissions regulations, technology and staffing challenges are shaping school bus purchasing and operations.

The panelists said fleets should take a holistic approach to fleet electrification that considers funding, reliability and performance alongside emissions compliance. They noted that software and automatic updates can improve efficiency by reducing service visits. The panelists also highlighted vehicle-to-grid capabilities, describing electricity as a low-cost energy that could provide districts with additional operational and community benefits.

Responding to attendees’ questions about electric school bus service, the panelists acknowledged that workforce shortages remain a significant obstacle. “There is a shortage of qualified EV techs and it is an industry issue,” they said. The lack of trained technicians can extend repair delays and discourage districts from adopting electric vehicles, making local service capacity an important consideration before purchasing buses.

The panelists reported progress on electric bus diagnostics and trouble codes, as well as efforts to reduce repair times through third-party battery assistance. Regarding parts availability, speakers confirmed that, “The parts channels are in better shape than they were a year ago in general.”

Cold-weather performance was another focus. The panelists pointed to electric fleets successfully operating in Canada and Alaska and explained how battery thermal management systems both heat and cool the batteries.

They also advised B20 users to closely monitor storage and maintenance because biodiesel attracts water. Cummins, they established, continues evaluating alternative fuels and investing in gasoline products to give districts more fleet-diversification options.

McGinn highlighted the first school bus application for the fourth-generation 14Xe ePowertrain by Cummins-Meritor. The system integrates the motor and transmission and, he said, its three-speed configuration “allows [drivers] to operate the vehicle with better range.”

IC Bus

Matthew Milewski, connected vehicle marketing director for IC Bus parent company Navistar, joined Chad Duncan, specification manager for IC Bus and Maurine Simons, transportation director for North Mason School District in Washington state, to discuss using data to improve fleet safety, maintenance and efficiency.

Milewski said student transportation departments are under increasing pressure from technician and driver shortages, limited budgets, safety requirements, parent expectations and sustainability goals. With many operations “doing more with less,” he explained that connected buses can help answer routine questions about vehicle locations, delays, maintenance needs, driver performance and developing mechanical problems.

Technology allows transportation departments to monitor routes, vehicle speed and timestamps, giving staff objective information when investigating incidents or responding to questions. Milewski said connected technology can also generate AI-driven weekly driver reports and flag events requiring additional review. Camera-based systems can alert drivers about issues such as failing to wear a seatbelt, while real-time information can support route adherence, stop accountability and parent communication.

Milewski contrasted traditional maintenance, where a driver must notice a problem before technicians diagnose it and order parts, with a connected operation. With the latter, the vehicle reports an issue to fleet managers, who can then order repair parts and schedule shop time before the bus arrives. He shared how the OnConnect Connection feature through IC’s My International fleet management system helps districts minimize downtime.

Simons shared that she began using the connected platform years ago as a technician, particularly to identify and order parts. After becoming transportation director, she continued using it to track bus information and save staff time.

Duncan advised directors purchasing vehicles to use operating data when specifying horsepower, transmissions, fuel capacity, axles, tires or electric bus battery range. He urged attendees to stay ahead of state safety regulations and plan realistically for fleet advancements in safety technology.

Milewski encouraged directors to ask, “What information do I wish I had every day that I don’t have today?” and “What decisions am I still making based on assumptions?” He added that My International is available through dealerships with a five-year subscription and can support mixed fleets, not only International buses.

Suburban Propane

Suburban Propane sales representative John Barnett moderated a discussion with Douglas Dagan, executive vice president of renewable energy at Suburban Propane; Scott Bradley, executive vice president at Pioneer eMobility; Brad Beauchamp, EV product segment leader for Blue Bird; and Nikita Mishra, industry application engineer for ABB’s automotive and battery manufacturing segment. They examined how off-grid charging and microgrids can help districts deploy electric buses despite utility delays or limited grid capacity.

Beauchamp advised transportation directors to evaluate infrastructure as soon as funding is identified, and district leadership approves an electric bus project. Asked when that process should begin, he replied, “That actually comes before you order the bus.”

He and Mishra agreed that early discussions between the district and utility will determine their power demand, equipment availability and desired mix of energy sources before design work begins.

Mishra revealed that infrastructure projects can take anywhere from several months to several years. She noted that lead times for some equipment, including transformers, can reach 75 weeks.

Likewise, Bradley urged districts to “call your utility early.” He said Pioneer eMobility can deliver certain systems within three to four months.

When permanent infrastructure is delayed, propane-powered off-grid charging systems can serve as a temporary or supplemental solution.

“Propane is available everywhere,” Gagan noted, adding that renewable propane is a fast-growing option that is chemically identical to conventional propane but produced from renewable sources.

Bradley pointed to Los Angeles Unified School District, where 180 of 220 electric Blue Bird buses are charged using “25 off-grid electric vehicle charging microgrids.”

Panelists said mobile charging can also support field trips, sporting events and emergency operations or help districts test potential sites before installing permanent infrastructure. Barnett explained how microgrids combining propane generators, battery storage and other energy sources could charge buses and power facilities during outages or reduce demand charges through peak shaving.

Speakers encouraged districts facing grid constraints to consider the entire charging “ecosystem,” including the bus, chargers, generation source and future vehicle-to-grid or vehicle-to-building uses.

Thomas Built Buses

Mark Childers, powertrain and technology sales manager for Thomas Built Buses, moderated a discussion with Alec Watson, account manager for Daimler Truck Specialty Vehicles within Cummins, and Trystan Thomas, director of transportation for Shasta Union High School District in California. They discussed evolving diesel technology, Cummins’ forthcoming B6.7 Octane gasoline engine and the factors districts should evaluate when selecting powertrains.

Watson said the B6.7 Octane was developed for the medium-duty and school bus markets using feedback from OEMs and customers. Built on the B6.7 diesel platform, the gasoline engine is designed to provide a similar torque curve, drivability and performance while eliminating diesel exhaust fluid and diesel particulate filter management. Cummins, Allison Transmission and Thomas Built Buses are collaborating on its integration.

Thomas Built Buses expects production to begin during the first quarter of 2027, initially for the Saf-T-Liner C2 school bus. Panelists clarified that the engine will meet the EPA’s near-zero emissions standard but is not a zero-emissions product. It will initially be offered only on new buses, not as a retrofit.

Watson said Cummins has trained and certified approximately 700 to 750 dealers on the new engine. Technicians already certified on the B6.7 diesel can complete an online course and test rather than attend additional in-person technical training. Cummins is also preparing its Cummins Care technical support operation and adding field service engineers.

Thomas encouraged directors to examine route mileage, terrain, field trips, infrastructure, technician capabilities and total cost of ownership. His district remains predominantly diesel because some routes exceed 120 miles per day, including steep grades or support out-of-town trips. “Anything alternative, you just got to do your homework,” he said.

Districts must also examine funding carefully. Thomas recalled receiving $5,000 per bus for electric infrastructure that ultimately cost $70,000, requiring the district to supply the difference.

Watson cautioned directors against selecting a technology simply because it is exciting. “Just because the octane engine is new and shiny doesn’t mean it’s necessarily for you,” he said.

“I believe that successful fleets will remain technology-neutral and evaluate solutions based on the operational fit rather than the trends alone,” Thomas agreed. “The future is likely to include a mix of diesel, gasoline, propane, natural gas and battery electric solutions.”
