Arizona Public Service (APS) wants to raise electricity rates by 45% for data centers and 15% for households. The proposed increases, if approved, could reshape the state's tech sector and hit family budgets.
The proposed increases
Under the plan filed with regulators, APS would charge data centers nearly half again as much for power. Residential customers would see a smaller but still steep jump. The utility says the hikes are needed to cover rising costs and infrastructure investments.
Impact on data center investments
The 45% hike sends a clear signal to the tech industry. Data centers guzzle electricity — servers run around the clock, cooling systems rarely shut off. Arizona has been a growing hub for such facilities, drawn by cheap land and favorable climate. A rate increase of this size could push companies to look elsewhere. The proposal may deter new data center projects and slow the state's tech-driven economic growth.
For families already dealing with inflation, a 15% rate hike adds another monthly cost. APS serves roughly 1.4 million customers, and many were already watching their bills rise. The utility argues the increase is necessary to maintain reliability and meet demand. Critics say it's too much, too fast.
Next steps
The Arizona Corporation Commission must vote on the proposal. Hearings could draw testimony from tech firms, consumer advocates, and business groups. The outcome will determine whether Arizona keeps its edge in attracting data centers — and how much residents pay to keep the lights on.
