Key facts
- Arizona Public Service is proposing a 45% electricity rate increase for data centers.
- Residential electricity rates are proposed to increase by 14.5%.
- The proposed increases are driven by the rising power demands of data centers, particularly for AI.
Phoenix is experiencing a significant boom in data center construction, fueled by the increasing demand for artificial intelligence (AI) and its substantial power requirements. This growth, however, is straining the local power grid and leading to proposed electricity rate hikes by Arizona Public Service (APS), the state's largest utility. APS is seeking to increase electricity rates for data centers by 45% and for residential customers by 14.5%. The utility attributes these proposed increases to the need to invest in grid infrastructure to meet the growing demand, particularly from AI-driven workloads. The proposed hikes have generated significant opposition from both the data center industry and residential consumers, who are unhappy with the potential cost increases.
