Clayco and Kiewit New Mexico Co. have completed the structural topping out of the first building at Project Jupiter, an 855,000-square-foot data center campus in Doña Ana County, New Mexico, developed by Stack Infrastructure and Oracle. The campus broke ground in October 2025 and will ultimately span 1,400 acres with four data center buildings, natural gas power plants, a battery storage center, and a desalination plant. Oracle will occupy the site to host AI infrastructure for OpenAI, with potential capacity reaching 2.5 GW at full build-out. The project will use non-potable well water and on-site Bloom Energy fuel cells for cooling and power, with no public drinking water consumed.
At up to 2.5 GW, Project Jupiter represents one of the largest single data center campuses under construction in the United States, reflecting the scale of infrastructure investment being made to support AI workloads for major cloud and AI companies. The campus's on-site power generation and closed-loop water systems are a direct response to concerns about strain on local grids and water supplies, a model that other large-scale developers may reference as regulatory scrutiny of data center resource use grows.
A named large-scale data center campus in New Mexico reaching a construction milestone (topping out) is a concrete, verifiable construction event. US location and named project make it newsworthy and distinct from previously published stories.
