Phase 1 would rely on on-site natural gas turbines as primary power source, transitioning to solar as adjacent solar projects come online. Utility-scale battery storage included in original 3 GW plan. Hybrid model: gas + solar + battery + WAPA grid. On-site generation MW not specified in any source.
Developer's attorney stated commitment to air-cooled or closed-loop cooling to minimize water demand. Site borders the Greene Canal, raising concerns about water access and consumption in an arid region. No MGD figures have been published. Critics cited Pima County's 'Project Blue' hyperscale data center as a cautionary precedent for water misuse in Arizona desert developments.
Community sentiment
All approximately 60 public comments and 50 emails received by the Pinal County Board opposed the project. Concerns raised: location in a high-risk flood zone, wildlife and environmental impacts, water use risk, power bill impacts for local residents, construction timeline (gas plant likely last, 5-7 year timeline). Scale-back from 3 GW to 1 GW was a direct response to this opposition. Pinal County Supervisor Rich Vitiello expressed concern about constituent energy cost impacts.
