400MW from in-state solar and wind farms committed for Phase 2 buildout

Google built the Mesa campus as air-cooled, chosen for Arizona's watershed scarcity; Mesa's economic-development director described it at groundbreaking as a 'cutting-edge, air-cooled data center campus.' The 2019 City of Mesa development agreement separately provided for the city to supply up to ~1 million gallons/day at launch, scaling toward ~4 million gallons/day at full build-out — a contractual water allocation/backup (on-site storage, existing wells, acquired water rights, long-term storage credits), not confirmed operational cooling consumption. No operational water-use figure has been published.

Public subsidies

Community sentiment

Supported

Mesa City Council approved the $1B development and GPLET agreement in July 2019 (Mayor John Giles called it 'a home run'); one councilmember abstained as a Google shareholder and voiced reservations about large-corporation tax breaks. The city projected net positive tax revenue.
