Tucson Unified's Solar Generation Program Shines Bright

Tucson Unified has one of the largest on-site solar generation programs among K–12 school districts in the nation. The project began in 2013 and was completed in 2018 through three distinct phases. It consists of three Solar Service Agreements that generate electricity at 80 district sites. Collectively, the systems provide approximately 23 megawatts (MW) of generating capacity, produce about 40.7 million kWh annually, and offset roughly 41% of the district’s electricity consumption.

The installations include solar canopies over playgrounds and parking lots, as well as one rooftop-mounted system. While additional rooftop installations were evaluated, considerations related to roof warranties and structural capacity were significant factors in limiting rooftop deployment.

The district elected to enter into Solar Service Agreements rather than directly purchasing and owning the systems. This approach allowed TUSD to implement the projects without the substantial upfront capital investment required for ownership. An important feature of these agreements is that the district negotiated a no-escalator rate, meaning the price TUSD pays for solar-generated electricity remains fixed throughout the term of the agreements.

This is important because it provides long-term budget certainty and protects the district from utility rate increases. As utility rates have continued to rise over the years, the fixed solar rate has generated increasing savings and enhanced the overall financial value of the program.
The financial benefits have been significant. First year savings were approximately $302,000. For the fiscal year ending June 30, 2026, annual savings are projected to be approximately $1.715 million. Cumulative savings to date are estimated at $13.1 million, and total savings through 2037 are projected to reach approximately $37.8 million.

“This has been one of the most exciting and rewarding projects I have had the opportunity to work on,” says Tina Cook, TUSD’s Energy Project Manager. “In addition to reducing utility costs, the program has provided shaded parking and playground areas while demonstrating the potential for large-scale solar generation in our community.”
