How Wa-Nee Community Schools cut fuel costs with propane-powered buses

Currently, 25 of Wa-Nee Community School District’s 56 buses operate on propane autogas. These buses help safely transport over 2,500 students daily and log approximately 450,000 miles annually.
By next school year, propane-powered buses will account for half of the district’s fleet, with additional buses planned for 2027. The timing is ideal, as the upcoming 2027 EPA emissions standards are expected to add $12,000 to $15,000 to the cost of every new diesel engine.
“I would be in full panic mode if I were purchasing diesel next year,” Rosa said. “Because my fleet is mostly propane autogas, I don’t have to lose sleep over that.”
As a domestically-produced fuel, propane autogas pricing is less exposed to the volatility impacting diesel and gasoline markets. While recent spikes have made its cost advantage even more apparent, the significant savings seen by Wa-Nee are increasingly common among fleets nationwide.
“Districts, municipalities and businesses across the U.S. operating fleets with propane autogas are reporting annual savings of up to $1M in fuel costs alone compared to diesel,” Joel Stutheit, senior manager, autogas business development for the Propane Education & Research Council (PERC) said. “That includes districts right here in Indiana protecting budgets and reducing emissions by adopting propane autogas.”
About Propane Autogas
Propane autogas is widely used by school districts across the United States because of its lower fuel costs, stable domestic supply, and reduced emissions and maintenance requirements. More than 23,000 propane autogas school buses operate across 1,100 districts in 49 states, safely transporting over 1.3 million students every day.
Controlled, Low Costs
Because propane autogas is stable and doesn’t degrade in storage, districts like Wa-Nee can utilize bulk tanks and lock in predictable pricing with 12, 24, or 36-month contracts — even further hedging against the market volatility associated with gasoline and diesel.
Simplified Maintenance
Propane autogas eliminates the need for complex after-treatment systems, significantly lowering maintenance costs and extending engine life. This has allowed the district’s single in-house mechanic to maintain all 56 buses more efficiently, which wouldn’t be possible with a fully diesel fleet.
Cleaner Air & Quieter Rides
Propane autogas buses significantly reduce emissions, producing far less NOx and particulate matter, no visible smoke, and quieter operation for students and drivers.
Winter Reliability
While diesel can gel in freezing temperatures, propane autogas buses have proven more reliable during Indiana winters, allowing Wa-Nee schools to stay open even when surrounding schools were forced to close due to diesel-related fleet issues.
“I never want to miss school; our job is to get kids there,” Rosa said. “Even on the coldest winter mornings, I know our propane autogas buses will start, and I know we can stay open.”
