Arizona residents oppose proposed data centers over resource demands

Arizona residents are organizing a bipartisan grassroots campaign against proposed data centers from Phoenix to Tucson, citing demands for water, power and land. The Verge reports that TSMC’s Arizona complex uses nearly 5 million gallons of Phoenix municipal water each day.

What happened

Key facts

  • Proposed data center developments from Phoenix to Tucson would require more water, power and land than residents are willing to provide, the article says.
  • A grassroots, bipartisan coalition of Arizona residents is opposing newer, larger data center developments.
  • The article says TSMC was welcomed by local leaders, while the first wave of data centers drew little attention.

The brief

A bipartisan grassroots coalition of Arizona residents is opposing proposed data centers from Phoenix to Tucson, objecting to the projects’ demands for water, power and land. The Verge describes the opposition as focused on newer, larger developments, as Arizona’s data center buildout draws scrutiny from residents.

The Verge says Arizona has 172 data centers and that the first wave attracted little attention. Local leaders welcomed Taiwan Semiconductor Manufacturing Company (TSMC), according to the outlet. The current opposition marks a shift from that earlier reception, though the article does not identify particular projects, developers or local government decisions.

Water use is a central concern in the account. TSMC’s Arizona complex draws nearly 5 million gallons each day from Phoenix’s municipal supply, The Verge reports. For comparison, the outlet says some hyperscale data centers, including Google’s facility in The Dalles, Oregon, use about 1.5 million gallons daily—roughly one-third of the amount it gives for TSMC’s complex.

The Verge places the debate in a state facing reduced Colorado River water supplies, saying Arizona will soon lose access to nearly 30 percent of the water it receives from the river.

The article connects that pressure to residents’ concerns about further large-scale demand, but does not quantify how much water the proposed data centers would use or identify their power and land requirements. The article also describes TSMC’s economic significance: the company initially projected a $12 billion investment in Arizona by 2029.

It estimates that TSMC controls 70 percent of the global chip market and says contracts with Apple and Nvidia make up more than one-third of the company’s annual revenue. Those figures provide context for the company’s place in Arizona’s technology sector; they do not describe the proposed data centers’ investments.

The Arizona Capitol Times headline separately states that Arizona needs more power and that embracing solar can help. It does not provide details in the headline about a specific power plan or how it relates to the proposed data centers.

The Verge’s account does not identify a response from the data center developers to residents’ campaign, or describe a vote, permit decision or other next step.

Why it matters

  • Phoenix’s municipal water supply is already providing nearly 5 million gallons a day to TSMC’s Arizona complex, a concrete example of the water demand residents cite.
  • Arizona residents opposing the proposed projects identify water, power and land as the resources at stake.
  • The Verge says Arizona will soon lose access to nearly 30 percent of the water it receives from the Colorado River, making water supply a stated part of the debate.
  • TSMC’s projected $12 billion Arizona investment and its contracts with Apple and Nvidia illustrate the company’s documented economic interests in the state’s technology sector.

What to watch next

  • Whether the grassroots coalition opposes specific proposed data center developments from Phoenix to Tucson.
  • Whether developers or local leaders address residents’ concerns about water, power and land.
  • Whether any data center proposal receives a permit or reaches a local government decision.
  • Whether Arizona’s power needs prompt action on solar, which the Arizona Capitol Times headline says can help.

How we got here

The immediate backdrop was Taiwan Semiconductor Manufacturing Company’s May 2020 announcement that it would build a semiconductor plant in Phoenix; construction began in 2021. The project placed large-scale technology development within Arizona’s existing water and power framework.

Arizona’s Groundwater Management Act, enacted in 1980, created Active Management Areas, including those around Phoenix and Tucson, and required new subdivisions in those areas to demonstrate an assured 100-year water supply.
