New charging infrastructure at the Hilltop Bus Terminal operated by Denver Public Schools delivers 650 kilowatts of total power across 26 plugs, supporting a district fleet that has grown to 28 electric school buses. The district recently added 25 Blue Bird Vision electric school buses to reach that total and says it now operates the largest electric school bus fleet in Colorado. Kempower supplied the hardware and served as technology partner on the project, which was led by industrial automation and electrical solutions provider Winn-Marion. The system is ready for the start of the school year on August 24, 2026.
Highlights
- 650 kilowatts of total power from a Kempower distributed charging system at the Hilltop Bus Terminal
- 13 dual-port Kempower Satellite dispensers providing 26 charging plugs
- 28 electric school buses in the district fleet, including 25 Blue Bird Vision units added recently
- Seven regions where Kempower now powers electric school bus depots: Denver, Quebec, Louisiana, Kansas, Massachusetts, Indiana, and Wisconsin
Inside the Hilltop Terminal Charging System
The terminal runs a Kempower distributed charging system rated at 650 kilowatts of total power. That capacity feeds 13 dual-port Kempower Satellite dispensers, yielding 26 plugs across the depot.
Kempower reports the system dynamically distributes available power across multiple vehicles rather than fixing output per dispenser. The company says the approach helps keep buses charged and ready for daily routes.
How Does Charging Fit a School Bus Schedule?
Depot charging for student transportation is constrained by fixed morning and afternoon route windows, which shapes how power gets allocated overnight and between runs.
“Electrifying a school bus fleet requires charging infrastructure that works around the realities of daily transportation schedules,” said Kempower North America President Monil Malhotra. “Kempower technology keeps electric school buses charged, ready, and on the road, helping Denver Public Schools deliver reliable, cleaner transportation for students every day.”
Fleet Growth Ahead of the School Year
The district’s recent addition of 25 Blue Bird Vision electric school buses brought its fleet to 28 units. According to the district, that total makes it the largest electric school bus fleet in Colorado.
Project Partners
Winn-Marion led the installation, with Kempower as hardware supplier. PowerFlex, formerly The Mobility House, handled smart charging and energy management.
“We couldn’t be more pleased with the entire team’s performance on this significant project,” said Jim Hussey, Electrification Solutions Specialist at Winn-Marion Companies. “Denver Public Schools is a smart, organized group, Kempower has been highly supportive from day one, and PowerFlex (formerly The Mobility House) has proven to be an outstanding partner in the Smart Charging and Energy Management space. We look forward to the opportunity to support other school districts throughout the Rocky Mountain region over the coming years.”
