Proposed data center in Pecos Road and the Crismon Road alignment, Mesa. Operated by NTT.

Where it stands

ABC15 reported on May 19, 2026 that Mesa's Planning and Zoning Board had approved the NTT project with conditions and that it still needed City Council approval. In August 2026 ABC15 reported that a city spokesperson said NTT was requesting minor modifications to the city's allowances, which is why the project kept appearing in meetings. Mesa issued Clayco a permit on October 13, 2026 for a stockpile of about 6,000 cubic yards labeled NTT Data Centers on the site.

The short version

Where does it stand with the city?

• The City Council approved a site plan and rezoning for the site on August 26, 2024 for an earlier development, which the staff report says never came to fruition before a new developer sought to revise the entitlements.
• The staff report says the application was submitted on August 4, 2025, before Mesa's Ordinance No. 5957 took effect, so it is processed under the standards in effect when it was filed.
• ABC15 reported on May 19, 2026 that the Planning and Zoning Board approved the project with conditions and that it still needed City Council approval.
• Mesa issued Clayco a permit on October 13, 2026 for a stockpile of about 6,000 cubic yards labeled NTT Data Centers.

How much did NTT pay for the land?

• The Maricopa County Assessor lists a sale price of $296,378,800 for the site's 7,412,696 square foot parcel, about 170.2 acres, owned by NTT GLOBAL DATA CENTERS PH10 LLC.
• Data Center Dynamics reported in March 2025 that NTT paid $300 million for 173 acres. The sources do not say whether this and the Assessor's sale describe the same purchase.
• Connect CRE reported that Levine Investments and Andrew Cohn owned the land and that Nathan & Associates Inc. and JLL negotiated the deal.

How big will it be and how much power will it use?

• Mesa's staff report describes seven data center buildings from 309,638 to 399,753 square feet, 2,257,581 square feet in all, plus a Salt River Project substation, a private substation and a city well site.
• A company spokesperson told Data Center Dynamics the first building would be available in November 2028. ConstructConnect reported up to 360 megawatts for the first phase by then, without saying what the figure measures.
• The staff report says the applicant has been working with Salt River Project on an electrical network for the site and sites directly west of it.

What about water and cooling?

• NTT's applicant narrative says each data hall building will have a closed-loop water cooling system filled up only once, with water from the City of Mesa.

Who has raised concerns?

• At the applicant's October 15, 2025 neighborhood meeting, two attendees raised concerns including noise from the substation and generators.
• ABC15 reported on August 15, 2026 that community activists oppose the plan over water use, job growth, wildlife and property values, and that a city spokesperson said NTT is requesting minor modifications to the city's allowances.
