Current through Register Vol. 30, No. 28, July 12, 2024
A. The Affected Utilities shall provide
				nondiscriminatory open access to transmission and distribution facilities to
				serve all customers. No preference or priority shall be given to any
				distribution customer based on whether the customer is purchasing power under
				the Affected Utility's Standard Offer or in the competitive market. Any
				transmission capacity that is reserved for use by the retail customers of the
				Affected Utility's Utility Distribution Company shall be allocated among
				Standard Offer customers and competitive market customers on a pro-rata
				basis.
B. Utility Distribution
				Companies shall retain the obligation to assure that adequate transmission
				import capability is available to meet the load requirements of all
				distribution customers within their service areas. Utility Distribution
				Companies shall retain the obligation to assure that adequate distribution
				system capacity is available to meet the load requirements of all distribution
				customers within their service areas.
C. The Commission supports the development of
				Federal Energy Regulatory Commission-approved Regional Transmission
				Organization (RTO), an Independent System Operator (ISO) or, absent a Regional
				Transmission Organization or an Independent System Operator, an Arizona
				Independent Scheduling Administrator (AISA). The Commission believes that such
				organizations are necessary in order to provide nondiscriminatory retail access
				and to facilitate a robust and efficient electricity market.
D. Affected Utilities that own or operate
				Arizona transmission facilities shall form an Arizona Independent Scheduling
				Administrator that shall file with the Federal Energy Regulatory Commission
				within 60 days of this Commission's adoption of final rules herein, for
				approval of an Independent Scheduling Administrator having the following
				characteristics:
1. The Arizona Independent
				Scheduling Administrator shall calculate Available Transmission Capacity (ATC)
				for Arizona transmission facilities that belong to the Affected Utilities or
				other Arizona Independent Scheduling Administrator participants and shall
				develop and operate an overarching statewide OASIS.
2. The Arizona Independent Scheduling
				Administrator shall implement and oversee the nondiscriminatory application of
				operating protocols to ensure statewide consistency for transmission access.
				These operating protocols shall include, but are not limited to, protocols for
				determining transmission system transfer capabilities, committed uses of the
				transmission system, available transfer capabilities, Must-Run Generating
				Units, energy scheduling, and energy imbalances.
3. The Arizona Independent Scheduling
				Administrator shall provide dispute resolution processes that enable market
				participants to expeditiously resolve claims of discriminatory treatment in the
				reservation, scheduling, use, and curtailment of transmission
				services.
4. All requests
				(wholesale, Standard Offer retail, and competitive retail) for reservation and
				scheduling of the use of Arizona transmission facilities that belong to the
				Affected Utilities or other Arizona Independent Scheduling Administrator
				participants shall be made to, or through, the Arizona Independent Scheduling
				Administrator using a single, standardized procedure.
5. The Arizona Independent Scheduling
				Administrator shall implement a transmission planning process that includes all
				Arizona Independent Scheduling Administrator participants and aids in
				identifying the timing and key characteristics of required reinforcements to
				Arizona transmission facilities to assure that the future load requirements of
				all participants will be met.
