Denver Public Schools Opens Colorado's Largest Electric Bus Charging Hub
A new 650 kW facility at Hilltop Bus Terminal supports a growing fleet of 28 electric buses.
Denver Public Schools (DPS) has opened a new electric school bus charging hub at its Hilltop Bus Terminal, establishing the largest electric fleet in Colorado. The infrastructure marks a significant step in the district's transition away from diesel-powered transportation to improve air quality and reduce carbon emissions.
The new facility features a Kempower distributed charging system with a total power capacity of 650 kW. The hub is equipped with 26 charging plugs, provided via 13 dual-port Kempower Satellite dispensers. This infrastructure supports a fleet that has expanded to 28 electric buses following the recent addition of 25 Blue Bird Vision electric models. These electric vehicles now represent 12% of the district's total yellow school bus fleet.
Strategic Environmental Goals
The project was led by electrical systems provider Winn-Marion, with Kempower serving as the hardware supplier. This expansion is a key component of a broader environmental strategy by Denver Public Schools, which aims to reduce its overall greenhouse gas emissions by at least 90% by 2050. By replacing traditional internal combustion engines with electric alternatives, the district is targeting one of the primary sources of its carbon footprint.
Economic and Health Implications
The transition involves a steep initial investment, as electric school buses cost approximately $400,000 each. However, the district expects significant long-term operational savings. Annual fuel costs for an electric bus are estimated at $1,900, compared to $6,800 for a diesel equivalent. For the 25 newly added buses alone, DPS projects annual fuel savings of approximately $123,000.
Beyond the balance sheet, the shift addresses critical public health concerns. The American Lung Association has linked diesel exhaust to lung damage and asthma, making the removal of these emissions from school zones a priority for the health of the students relying on district transportation.
Future Outlook
As DPS continues to scale its electric fleet, the Hilltop Bus Terminal hub serves as a blueprint for the infrastructure required to sustain zero-emission transit at scale. While the current fleet represents a small fraction of the total district vehicles, the successful integration of the Kempower system provides the technical foundation for further expansion. The district will now monitor the real-world performance and maintenance cycles of the Blue Bird Vision buses as it works toward its 2050 emissions targets.
