“the Company's rate design should mitigate significant cross-subsidization by those customer classes that are not directly contributing to the costs caused by significant and concentrated system load growth among large high load factor customers, such as data centers. For this reason, APS's rate request proposes to adjust its cost-allocation methodologies and rate designs for these general service customers to ensure that growth is paying for growth”

“This effort is focused more specifically on data center customers because they are the largest and fastest growing subset of large high load factor customers within APS's service territory. This is consistent with comments made in Chairman Thompson's letter in Docket No. E-00000A-25-0069: "...it's important to balance the economic opportunities presented by data centers with the need to financially protect other ratepayers to ensure they are not bearing the rising energy generation and transmission costs associated with this burgeoning industry."”
