The BrightNight Box Canyon Project

Industry-leading solar solution serving the Southwest Public Power Agency

The BrightNight Box Canyon Solar Project, is a 300-megawatt solar power solution located in Pinal County, Arizona. Power produced by the Box Canyon project will serve the Southwest Public Power Agency (SPPA). SPPA provides power to 25 different smaller electric Co-Ops and utilities throughout the state of Arizona.  Six of these utilities (Electric District (ED) 2, ED3, ED4, ED6, and the Ak-Chin and Gila River Districts) are located in Pinal County proper.

BrightNight is proud to deliver SPPA’s largest ever renewable power purchase with our optimized design responsible for industry-leading safe, reliable, affordable electricity.

Following well-drilling activities started in Nov 2023, construction of the Box Canyon project is scheduled to continue with road improvements along SR79 in early March (2024).  Site work (clearing and grading) is planned for the second half of March, which will be followed by approximately 15 months of construction. Completion of the project is expected by Q2 2025.

Box Canyon Solar Project Benefits

While many are familiar with the environmental benefits of clean, renewable power, the Box Canyon project will also provide a series of other benefits to its community.

For instance, solar projects generate millions of dollars of property tax revenue for the county where they’re located. Because this revenue is created without the addition of significant numbers of new residents, the county is able to lower taxes on its current residents or provide new services—or both!

Another great benefit of this project? Solar projects like Box Canyon conserve Arizona’s precious water (~260 million gallons annually for this project alone). That’s because solar, unlike traditional steam-powered turbines, doesn’t consume water for each unit of energy (kWh) produced.

A summary of the project’s key benefits include:

  • 300-megawatts

    Of clean renewable energy

  • $43M

    of projected tax revenue for Pinal County over the 40-year project life

  • $134.6M

    In economic activity over 35 years

  • 300

    Jobs created during construction

  • 4

    Long-term O&M employees

  • 260 million gallons of water

    Avoided each year of operation

Box Canyon Begins Construction

BrightNight’s Box Canyon project celebrated its official groundbreaking in November 2023 along with Governor Hobbs of Arizona, our project customer the Southwest Public Power Agency, and the many community members who helped make Box Canyon possible. Construction is expected to conclude in Q2 2025. The Box Canyon project is a valuable investment for the local community and its benefits go far beyond the reliable, affordable, clean energy generated. BrightNight is proud to partner with Natural Restorations, an incredible organization prioritizing veteran employment and focused on the beautification and care for Arizona’s stunning natural landscapes. A selection of native plants were safely removed from our project site and transplanted in burn scarred areas of the region. Additionally, in an effort to foster future-proof workforce development, BrightNight is proud to support Central Arizona College with a scholarship supporting 50 students enrolled in the Commercial Electricians Program. Graduates of the program will be well-positioned to begin careers in the exciting renewable energy industry.

BrightNight projects are not possible without the support of our project communities. We are excited to tailor our local support to address important conservation and workforce initiatives and help share in the success that comes from an investment in renewable power.

We go beyond the standard renewable power project.

The Box Canyon project is a model of baseload renewable power. At over 900,000 MWh of projected annual production, our project will provide a remarkable amount of clean energy over its lifetime.

One year of Box Canyon Clean Power is equal to:

  • Local homes and businesses supplied with clean power

    77,299

  • Metric tons of CO2 removed from the environment

    641,893

  • Pounds of Coal not burning

    +709M


We are committed to sustainable infrastructure

Low Water Use

Solar electricity is a smart choice for water conservation. The project’s total annual water use for cleaning is less than what a typical family of four uses in one year.

Partnerships Incoming

BrightNight is partnering with local groups to use plants from our project site for community beautification and the restoration of burn scarred areas in the region.

Construction Has Begun!

The Box Canyon Project began construction in November 2023. The construction is expected to be complete by Q2 2025.
