Arizona data center and energy bills

What it would do: Allows utilities to construct new plants colocated with large industrial energy users without obtaining a certificate of environmental compatibility, provided the utility gives 30 days' notice and holds a public comment session. Requires the commission to adopt rules defining colocation and large industrial energy user.

What it would do: Requires county comprehensive plans to include planning for data centers and small modular reactors with sufficient location and extent designations to not prevent their effective use, and requires counties above certain population thresholds to amend plans within two years.

What it would do: Requires the State Land Department to develop a map within two years identifying state land parcels best suited for computer data centers, in consultation with the industry, and to consider this map when creating land use plans.

What it would do: Allows large customers with at least 25 megawatts peak demand to generate and self-supply electricity through dedicated generation and private lines, subject to registration with the Arizona Corporation Commission and restrictions on serving only the customer and affiliated loads.

What it would do: Requires public power entities and the corporation commission to mandate that large data centers with peak demand of at least 100 megawatts pay all energy costs related to their operation, preventing those costs from being passed to other customers.

What it would do: Requires public power entities and the corporation commission to make large load customers using at least 50 megawatts at a single site pay for all energy costs they incur, preventing those costs from being passed to other customers.

What it would do: Amends Arizona's computer data center tax relief statute to change the application deadline from December 31, 2033 to December 31, 2026, preventing the authority from certifying new computer data centers that submit applications after the earlier date.

What it would do: Repeals the computer data center tax relief statute. Adds new requirements that computer data centers use only renewable energy with battery storage and limit water cooling to 115 gallons per day per 1,000 square feet, effective December 31, 2026, enforced by the Corporation Commission.

What it would do: Requires computer data center owners or operators to submit a cost responsibility agreement with the electric utility serving the facility, obligating them to pay all costs associated with dedicated upgrades required to serve the data center, as a condition for tax relief certification.
