Highlights
Casa Grande’s Planning and Zoning Commission unanimously approved a permit for the Samba Energy Center battery energy storage facility on April 2, 2026.
The 36-acre facility will deliver up to 650 megawatts of electrical output to a proposed APS substation north of the site.
Kirk McCarville, a local land broker, told the commission the surrounding industrial park cannot currently support projects requiring more than 10 megawatts of power, limiting its ability to attract large employers.
Construction is estimated at $400 million to $660 million, with a projected start date of March 2028.
The project is projected to generate $8.6 million to $14 million in tax revenue to the city over its lifetime.
The facility will require no water, sewer, or fuel connections.
The Casa Grande Fire Department has met with the applicant and will receive additional emergency response training from the applicant’s third-party consultant.
The approval includes conditions requiring the applicant to submit an Emergency Response Plan and a Hazardous Materials and Spill Management Plan, binding on all future property owners.
