The University of Washington has finished construction on a solar canopy system in a large parking area situated north of Husky Stadium, marking a significant step toward achieving its sustainability objectives.
This pilot installation features an 84-kilowatt solar energy system combined with Level 2 electric vehicle charging infrastructure that can simultaneously charge 20 vehicles. The initiative, which cost $3.7 million, also includes the electrical framework necessary for potential future expansion that could support solar panels generating nearly 2.5 megawatts of power — sufficient to supply electricity to approximately 2,000 residential homes.
Mark Huppert, who serves as interim director of UW Transportation Services, explained that this solar canopy pilot project aligns with the university’s carbon reduction targets. He noted via email that the location, built on what was previously the Montlake landfill site, exemplifies how such land can be utilized for more environmentally sustainable purposes.
The project involved several key partners, with Sea Con serving as general contractor and Prime Electric handling electrical contracting duties. Trinity Structures, now operating under the name Trinity Energy, manufactured the canopy structure.
The system connects to both the City of Seattle’s electrical grid and the university campus’s power network. By producing energy on-site, the university can decrease its dependence on utility grid power while also mitigating the effects of power interruptions and variable electricity pricing.
Darin Leonard, president of Trinity Energy, emphasized in a statement that while producing solar energy from a parking facility might appear modest in scope, its strategic importance is substantial.
The concept originated from cooperative efforts involving the student group UW Solar, Anne Eskridge, former director of UW Transportation Services, and Jan Whittington, who directs the UW’s Urban
Infrastructure Lab.
The university is presently developing its 2050 Sustainability Action Plan, which incorporates plans for long-term expansion of solar canopy installations throughout the parking lot area. According to Huppert, UW Solar students plan to remain involved in efforts to realize the complete build-out vision.
Financial support for the project came from multiple sources: UW Transportation Services, Seattle City Light, and Washington state’s Climate Commitment Act, which was administered through the Washington State Department of Commerce’s electric vehicle charging program.
The installation represents an innovative approach to dual-purpose infrastructure, transforming a parking facility into a renewable energy generation site while simultaneously supporting the transition to electric vehicles. The strategic location near Husky Stadium ensures the facility will receive significant use during athletic events and other campus activities.
The infrastructure laid during this initial phase positions the university to dramatically scale up solar generation capacity in the future. The electrical systems installed can support an expansion to 2.5 megawatts, representing a nearly 30-fold increase from the current 84-kilowatt capacity.
This project demonstrates how educational institutions can repurpose existing facilities to advance clean energy goals while maintaining their primary functions. The parking lot continues to serve its original purpose while now also contributing to the university’s renewable energy portfolio.
The combination of solar generation and EV charging creates a comprehensive clean transportation solution, allowing electric vehicle owners to power their cars with renewable energy generated on-site. This integrated approach maximizes environmental benefits while providing practical amenities for the campus community.
As the university moves forward with its long-term sustainability planning, this pilot project will provide valuable data and experience to inform future renewable energy initiatives across the campus.
