Continued development of Copper Crossing

The proposed continued development will complement the existing solar generation at the site and is expected to feature generating resources needed to support and enable SRP’s transition to a lower carbon resource portfolio.

    SRP to Develop Utility-Scale, Advanced Solar Generation at Copper Crossing Energy and Research Center

    The SRP Board of Directors this week approved the second phase of continued development at the Copper Crossing Energy and Research Center in Florence, AZ, which includes a utility-scale advanced solar generation facility capable of generating up to 55 megawatts (MW) of solar energy, or enough to power approximately 12,000 homes. For more, view the press release.

    SRP plans to seek approval from its Board of Directors to continue the development of the Copper Crossing site. This development will take place on the land owned by SRP adjacent to the existing Abel Substation on West Judd Road and the Copper Crossing Solar Ranch on West Bella Vista Road in Florence, Arizona, to create the “Copper Crossing Energy and Research Center.”  

    The proposed continued development will complement the existing solar generation at the site and is expected to feature generating resources needed to support and enable SRP’s transition to a lower carbon resource portfolio, including advanced solar technology, two flexible natural gas turbines with a total output of less than 100 megawatts (MW), and small-scale long-duration energy storage (LDES) technologies, to be developed in phases over the next few years. Additional phases of development of the site may be proposed at a later date and would continue to explore various resources such as solar, storage, additional flexible natural gas turbines, or other resources SRP may need that best fit its system needs and requirements as we transition to a more sustainable resource mix.

    SRP Management is currently in the process of developing proposals for phase 3 of the project, which will include long-duration energy storage pilot projects. SRP Management plans to seek approval from the SRP Board for Phase 3 early in 2023.

    Phase I project information: Flexible natural gas generation

    On Sept. 12, the SRP Board approved the first phase of continued development at the Copper Crossing site located on land owned by SRP adjacent to the existing Abel Substation on West Judd Road and the Copper Crossing Solar Ranch on West Bella Vista Road in Florence, Arizona.

    Phase 1 consists of the installation of two flexible natural gas turbines with a total output of less than 100 megawatts (MW) and facilities needed to interconnect the turbines to the power grid. A series of 69 kV poles, lines and infrastructure will connect the new facilities to the existing Abel Substation.

    In November 2022, we expect to begin preparing the site for general construction activities. You might also notice construction fencing and other equipment on-site.

    Phase II project information: Advanced solar generation

    On Dec. 6, the SRP Board approved Phase 2 Advanced Solar Generation at Copper Crossing. This development will take place on the land owned by SRP adjacent to the existing Abel Substation on West Judd Road and the existing Copper Crossing Solar Ranch on West Bella Vista Road in Florence, Arizona, to create the Copper Crossing Energy and Research Center.

    The Phase 2 Solar Generation project will consist of photovoltaic solar arrays capable of generating up to 55 megawatts (MW). The Phase 2 Solar Generation will be located west of Attaway Road at the Copper Crossing Energy and Research Center and cover approximately 270 acres. SRP will develop, own and operate the facility and implement advanced solar array technology that will provide improved efficiency and performance. The proposed project will provide carbon-free energy supporting SRP’s 2035 Sustainability Goals.

    Phase III project information: Energy storage

    SRP Management is in the process of developing a proposal for Phase 3 of the project, which will include long-duration energy storage pilot projects. SRP Management plans to seek approval from the SRP Board for Phase 3 early in 2023.
