Bill Summary · SB 1309

Legislative bill overview

SB 1309 authorizes funding and regulatory mechanisms for electric grid improvements in Arizona, likely addressing infrastructure modernization, resilience, and capacity expansion. The bill passed through the legislature but was vetoed by the Governor on April 18, 2025, indicating executive-level disagreement with its approach or provisions.

Why is this important

Arizona faces growing electricity demand from population growth and data center expansion, making grid modernization critical for reliability and preventing outages. How grid improvements are funded and regulated directly affects utility rates, ratepayer costs, and the timeline for infrastructure upgrades that affect all residents and businesses.

Potential points of contention

  • Cost allocation: Who bears the financial burden—ratepayers, utilities, or general funds—and whether the bill's funding mechanism is equitable across customer classes
  • Regulatory oversight: The degree of Arizona Corporation Commission authority versus utility company discretion in approving and managing improvement projects
  • Environmental/sustainability standards: Whether grid improvements prioritize renewable energy integration, resilience to climate impacts, or traditional capacity expansion
