Box Canyon Solar Farm

(Case #PZ-PA-002-21)

Project Overview

BrightNight and Cordelio Power are excited to bring to Pinal County a state-of-the-art project that combines clean renewable solar energy generation with advanced battery storage technology to harness the power of the sun … even after it sets. The Applicants have submitted a formal request to amend Pinal County’s Comprehensive Plan to “Green Energy Production” on 2,329 acres of unincorporated state land located on the west side of Hwy 79 just north of Arizona Farms Road. 

The proposed use is the development of a photovoltaic (PV) solar energy farm with battery energy storage that will connect into the local electrical grid at SRP’s Abel Substation via transmission lines. This site is expected to generate enough local clean energy to power approximately 55,000 homes each year, and to provide low cost, clean energy to electricity users in this region.  During construction, the project is estimated to bring approximately 250 new jobs to Pinal County and approximately $20 million in local tax revenue.  An additional benefit of the project is the contribution of up to an estimated $60 million in funding to Arizona’s K-12 public schools through annual lease payments for the use of state land for the project.  Box Canyon intends to be operational as early as 2023. 

Comprehensive Plan Amendment

Existing Land Use Designation:        Moderate Low Density Residential (1-3.5 du/ac) with a High Intensity Activity Center

Proposed Land Use Designation: Green Energy Production with a reduced Activity Center along Hwy 79

If approved, the Applicants will be processing a zoning change application to rezone the property from General Rural to Industrial-3 Planned Area Development to permit the solar use.

Developer: BrightNight and Cordelio Power

Estimated Jobs Created: up to 250 (with construction)

Community Benefits

  • Estimated construction jobs created: up to 250
  • Reduction in vehicular traffic: once operational, the solar farm is forecast to generate less than one-tenth of one percent of the daily traffic compared to uses allowed under the current comprehensive plan designation
  • Local property tax revenue: estimated at $20 million for Pinal County
  • Funding for K-12 education: up to $60 million in estimated lease payments to ASLD to benefit the state’s K-12 education trust and public schools
  • Community leadership: continues the tradition of Pinal County’s leadership in the clean energy industry
  • Energy independence: expected reduction use of and dependence on fossil fuels
  • Clean air: new zero-emissions energy source
  • A quiet neighbor – once operational, the solar farm’s limited maintenance requirements are expected to make it a non-intrusive community resident
  • Water use: once operational, the project is forecast to require extremely low water usage
