School Buses That Power Your Home: Colorado's Genius Two-Way Energy Hack

When you think of school buses sitting idle in a depot after the final bell rings, you’re probably picturing wasted potential. But the Cherry Creek School District just turned that downtime into a power play—literally.

Six new electric buses funded by a $2.4 million federal rebate partnership are now doing double duty in the Denver area. They haul kids to and from school by day, then pump excess energy back into the local power grid during peak evening demand when families crank up their air conditioners and cook dinner. It’s the kind of elegant solution that makes you wonder why we haven’t been doing this all along.

Here’s how it works: The buses charge overnight when grid demand is lowest, run their routes during the day, and still have hundreds of kilowatt hours left in their batteries when they roll back to the depot. That’s where the magic happens. Highland Electric Fleets designed a bi-directional charging system that lets these buses release stored energy back into the grid during late afternoon and early evening—exactly when homes need it most. Think of it as a distributed battery network on wheels, one that happens to be painted yellow and smells infinitely better than diesel.

For Cherry Creek School District interim superintendent Jennifer Perry, the math is compelling.“This partnership works to support our environmental goals while delivering long-term operational savings,”she said at the June 3rd groundbreaking for the new bus facility. Beyond the environmental win—fewer tailpipe emissions and far less noise pollution—there’s the practicality: electric vehicles have 95% fewer moving parts than their diesel counterparts, which means maintenance costs tank. With diesel prices still elevated, that’s real money in the budget year after year.

The impact scales impressively too. Highland Electric Fleets estimates that two dozen of these buses could help the grid manage the excess demand from 100 homes during peak hours. A couple hundred buses? That’s supporting over a thousand. We’re not talking about a niche experiment anymore—this is infrastructure thinking that could reshape how Colorado manages power demand while quietly revolutionizing school transportation.

The fact that Cherry Creek wasn’t charged a penny for the buses and the facility itself? That’s the sweet spot where environmental responsibility and fiscal sense actually overlap. And if other school districts are paying attention—and they should be—we’re looking at the blueprint for how to electrify transportation while strengthening the grid itself.
