Committee adopts amendment and advances grid-security bill after wide public comment on competition, EMP and cybersecurity

Senate Bill 15-01 directs the Arizona Corporation Commission (ACC) to conduct an annual security-grid review; among the bill's original provisions were requirements to research grid-management technologies, assess emerging technologies and require investor-owned utilities to rectify deficiencies identified in the review. The committee adopted a two-page chair's amendment that narrowed some original language, removed a requirement to assess emerging technologies, added a requirement to evaluate electromagnetic-pulse (EMP) risks, and made some previously mandatory items into encouragements rather than mandates. As amended, the bill still requires the ACC to evaluate generator and grid-management capabilities to protect against physical and cyber attacks and to review cybersecurity and grid-protection protocols every two years.

Public testimony: grid security and energy competition

Commentators who testified included representatives of the data-center industry, energy suppliers and engineers. Multiple witnesses said the state faces significant new peak-demand growth tied to data-center investments, and some called for energy-market reforms to allow businesses to purchase generation or contract directly with suppliers rather than being limited to incumbent investor-owned utility supply for generation. Industry witnesses said energy competition would provide more options for long-term contracts, potentially lower costs and enable specialized solutions for large energy consumers.

Other witnesses urged focus on grid security and resilience. Testimony emphasized both cyber and physical risks, included calls for annual technical reviews and planning that account for EMP risks and cross-sector dependencies, and asked that ACC and utilities coordinate on timelines and costs associated with rectifying identified deficiencies.

Committee action

The committee adopted the chair's 2-page amendment and then voted to give the bill a due-pass recommendation as amended; the clerk recorded 5 ayes, 2 nays and 1 not voting. Several members said they supported the amended approach because it narrowed mandatory requirements while preserving an annual review and EMP evaluation. Industry witnesses requested that the bill's earlier, broader energy-competition language be reinstated or pursued in a separate vehicle; the final, amended bill removed some competition provisions that had been in earlier versions.

Why it matters

The measure as amended directs regulatory review of grid security and cyber defenses while leaving some decisions about corrective actions and funding mechanisms to the ACC or to encouraged utility responses. Stakeholders underscored two competing objectives: (1) ensure reliable, secure power and protect against cyber/physical threats (including EMP scenarios) and (2) enable new economic development and provide cost-effective procurement options for large, energy-intensive businesses such as data centers. The committee's amendment reflects an attempt to preserve the security-review focus while narrowing statutory mandates that witnesses and members worried could have unintended consequences.

Speakers and evidence

Notable testimony included engineered and industry perspectives (Robert Bilicek, energy consultant; NRG representative Jem Turhall), data-center representatives arguing for energy choice (Ryan Groover and others), and public commenters urging robust cyber/EMP protections. The ACC and utilities were not the primary presenters at the hearing but the bill centers their regulatory role.

Ending

The committee's due-pass recommendation as amended advances SB 15-01 for further legislative consideration. The transcript shows clear stakeholder interest in preserving grid reliability and cyber defenses while pursuing economic opportunities for data centers and other large electricity consumers. Additional amendments and clarifications are possible as the bill moves forward.
