First building at Project Jupiter data center campus in New Mexico topped out. Structural work on first building complete, three more to go October 27, 2026 The first phase of Project Jupiter, a large-scale data center campus in New Mexico being developed by Stack and Oracle, has been topped out. Clayco and Kiewit New Mexico Co. this week announced the topping out of the first portion of the Project Jupiter data center campus in Doña Ana County, New Mexico, placing the final structural beam atop the facility and completing the building's primary structural framework. Oracle and Stack chose a Clayco and Kiewit joint venture as general contractors on the first 855,000-square-foot (79,432 sqm) portion of the data center campus, with the project breaking ground in October 2025. "As part of our commitment to building to make life better, Clayco is proud to reach this benchmark moment in the construction of Project Jupiter, ultimately helping meet America's rapidly growing demand for sustainable, advanced technology infrastructure," said Ryan McGuire, Clayco's president of construction and compute. "As the need for advanced technological facilities grows, so does Clayco's commitment to delivering high-quality data center projects that not only support billions in community investments and the creation of thousands of skilled jobs, but that utilize on-site power generation and sustainable water technologies to minimize impacts to local electric grids and water systems." Announced last year, the campus will span 1,400 acres with four data center buildings, micro-grid facilities, natural gas power plants, a battery storage center, and a desalination plant. Oracle will occupy the campus once construction is complete, and will use it to host AI infrastructure for OpenAI. The site could total up to 2.5GW at full build-out, though the project has reportedly faced challenges around securing a natural gas connection. "Reaching this milestone reflects the extraordinary coordination and commitment of the teams bringing Project Jupiter to life," said Mike Casey, COO of Stack Infrastructure. "From the outset, our focus has been to develop critical digital infrastructure in a way that delivers lasting value for Doña Ana County. Project Jupiter demonstrates how infrastructure at this scale can advance technological innovation while supporting local jobs, strengthening the regional economy, and responsibly managing energy and water resources. We are proud to work alongside Oracle, Clayco, Kiewit, and our local partners as we move this important project forward." The companies noted that no public drinking water will be used for data center cooling or fuel-cell operations. The site will use non-potable well water, purchased under contract from an existing New Mexico water-rights holder, for the initial, one-time fill of its four closed-loop, non-evaporative cooling systems. On-site Bloom Energy fuel cells will power a campus microgrid and also rely on non-potable water. Clayco is a real estate development and construction firm. Kiewit is a North American construction and engineering organization. "Kiewit is thrilled to reach this significant milestone in partnership with Clayco, Stack Infrastructure, and Oracle," said Tyler Nordquist, SVP, Kiewit New Mexico Co. "Projects of this scale are built through trust, collaboration, and an unwavering commitment to safety. Together with our partners, we're focused on delivering quality construction that supports our client's vision and creates lasting value for the community." "Together with our partners, we are building responsibly - investing in the energy infrastructure needed to protect local ratepayers and grid reliability, using closed-loop cooling systems designed to significantly reduce water consumption, and creating meaningful career opportunities and lasting economic value for Doña Ana County," said Mahesh Thiagarajan, EVP, Oracle Cloud Infrastructure. "We are pleased to work alongside our partners as we build the Project Jupiter data center to meet the growing nationwide customer demand for secure, reliable AI infrastructure."

Details emerge on $100B data center campus in Southern Virginia. Grading work may begin soon for Stack Infrastructure project * Stack Infrastructure's data center project in Pittsylvania County to include 21 data centers * Two on-site natural gas energy facilities also slated to be built * Regional authority allowing Stack to start grading land early before purchasing land for $737M Plans for a massive data center campus at the Southern Virginia Megasite at Berry Hill in Pittsylvania County are advancing rapidly. In March, the Danville-Pittsylvania Regional Industrial Facility Authority approved the sale of nearly 3,000 acres to a limited liability corporation connected to Stack Infrastructure, where the Denver developer and operator of data centers is planning to build a $100 billion "multi-campus digital infrastructure complex." The authority approved the sale for $737.8 million. In recent weeks, more details were revealed about the project as developers filed paperwork. In a project summary filed Oct. 8 with the Virginia Department of Environmental Quality, the campus will include 21 data centers requiring 3 gigawatts of power and two on-site natural gas facilities. Another recent development for the Stack project came Friday, when members of the authority voted to approve an early access agreement allowing Stack to begin grading about 400 acres of the property before purchasing the land. The company will pay $250,000 for the access. "They're in the process of wiring those funds over, and once that is received... they can get going," said Matt Rowe, Pittsylvania County's economic development director. Stack plans to buy 2,990 acres at the megasite, with the project occupying about 1,733 acres, according to the summary. Construction related to the permit is expected to begin in the third quarter of 2027. Under a May performance agreement with the authority, Stack will invest at least $73.5 billion at the site and create at least 2,050 jobs, with an average annual wage of $80,500. However, the company's planned investment is actually about $100 billion over three decades, with 2,500 jobs expected over 20 years, it says. Rowe has called the deal with Stack "one of the largest single-site investments ever announced in the U.S." A key requirement for a developer of a digital infrastructure campus, according to the summary, is that construction is able to begin quickly. "Speed is really key in order to meet business demands and customer demands," Rowe said. At full build-out, the authority expects the facility to generate up to $48 million per year in property tax revenue, according to the summary. That would be in addition to a tax on assessed equipment value. According to the summary, the property should have access to up to seven million gallons of water per day and up to three million gallons per day of sewer capacity. Danville's public utility has unused capacity of 12 million gallons of water per day and 14 million gallons per day of unused sewer capacity. The purchase and sale agreement between the authority and Stack specifies that, for the deal to move forward, Appalachian Power must provide a document stating it can supply the project a minimum load capacity of 299 megawatts by the end of 2028. The project would need a 150-megawatt substation by the end of the second quarter of 2028. According to the summary, a clear path to that goal is possible because of an existing on-site substation at the site with a 30 megavolt-ampere transformer and 138-kilovolt transmission lines. Other plans include the 80-acre Southwest Energy Generation Campus and the 125-acre Northeast Energy Generation Campus, according to the summary. By generating their own energy, developers can ensure that the project won't raise the electric bills of residents, according to Rowe. "One of the key ways of ensuring there's no impact to ratepayers is you're generating the electricity on site yourself," he said. RIFA acquired the property for the megasite in 2008, according to the summary. It encompasses 3,500 acres overall. Gainseville-based Wetland Studies and Solutions, an environmental services firm, prepared the summary, which is also expected to be filed with the U.S. Army Corps of Engineers.

Stack files for second building at Lancaster campus, Texas. Company looks to start work in March October 19, 2026 An affiliate linked to Stack Infrastructure has filed an application for a new data center outside Dallas, Texas. An application has been filed this month with the Texas Department of Licensing and Regulation for DFW02B. Located at 1130 E.

Construction on the $540 million project is set to run from March 2027 until December 2028. The application was filed by SI DFW02CAMPUS LLC, an affiliate that shares an address with Stack. The company first announced plans for a campus in Lancaster in April 2024. A Stack sales brochure describes its DFW02 project as a 500MW campus in South Dallas spanning 193 acres. The site could total five buildings (DFW02B would offer 54MW), totaling 1.76 million sq ft (163,509 sqm) and an on-site substation. Stack filed for DFW02A at 1000 E Beltline Road in January 2025. Construction on that 360,030 sq ft (33,448 sqm), two-story building is set to be completed in March 2027 - with follow-up works due to be completed in March 2028. Stack's DFW1 campus is located in Plano and could total 80MW across three buildings. QTS and Skybox also have projects in Lancaster. PowerHouse files for first building in Westlake. PowerHouse has revealed more details about the first building at its new campus outside Fort Worth, Texas. The company, via Circle T Owner LP, has filed with the TDLR for the DAL130 data center at the Circle T Ranch campus at 13572 N. Main Street in Westlake, Tarrant County. Construction on the 224,150 sq ft (20,824 sqm) data center is due to start in December 2026 for a June 2027 completion date. Some $83 million is set to be invested in the works. News that AREP-owned PowerHouse was looking to develop on the site (also known as 13580 Denton Highway) surfaced in August. Up to four buildings are reportedly planned, totaling 300MW. "The Circle T Ranch project remains in the planning and review process. The referenced filings are part of ongoing development planning, and any construction activity remains subject to applicable approvals and regulatory requirements," PowerHouse told the Dallas Morning News. Founded in 2022, PowerHouse has data center projects in operation and development across Virginia, Texas, North Carolina, Kentucky, Indiana, Illinois, Nevada, and Pennsylvania. A division of American Real Estate Partners (AREP), PowerHouse says its portfolio and pipeline totals more than 8GW of capacity. Investment giant Brookfield recently took a minority stake in AREP. PowerHouse has a sizable existing presence in Texas. In March, it topped out a 201MW data center in Irving, Dallas, and it is currently developing a 768-acre campus with Provident Data Centers just south of Dallas in Ellis County. The firm also looks set to develop on Tract-owned land outside Austin, and recently secured approval for a new behind-the-meter data center project outside Austin.
