Customer Data Modernization Initiative (CDMI)
The CDMI is intended to replace the Company's aging and outdated customer data systems. Approval of the application would allow the Company to track and defer the costs associated with the CDMI, so that the Company can present the Arizona jurisdictional portion of the costs to the Commission for review and consideration in a future rate case.
Decoupling and Delivery Charge Adjustment Provision (DCA)
The DCA specifies the accounting procedures and rate setting adjustments necessary to assure the Utility neither over-recovers, nor under-recovers, the margin-per-customer amounts ized in its most recent general rate case proceeding.
