• | An authorized return on common equity of 10.0%; |
• | A capital structure comprised of 46.1% debt and 53.9% common equity; |
• | A test year ended December 31, 2010, adjusted to include plant that is in service as of March 31, 2012; |
• | Deferral for future recovery or refund of property taxes above or below a specified 2010 test year level caused by changes to the Arizona property tax rate as follows: |
• | Deferral of increases in property taxes of 25% in 2012, 50% in 2013 and 75% for 2014 and subsequent years if Arizona property tax rates increase; and |
• | Deferral of 100% in all years if Arizona property tax rates decrease; |
• | A procedure to allow APS to request rate adjustments prior to its next general rate case related to APS’s acquisition of additional interests in Units 4 and 5 and the related closure of Units 1-3 of Four Corners (APS made its filing under this provision on December 30, 2013, which would result in an average bill impact to residential customers of approximately 2% if approved as requested); |
• | Implementation of a Lost Fixed Cost Recovery (“LFCR”) rate mechanism to support energy efficiency and distributed renewable generation; |
• | Modifications to the Environmental Improvement Surcharge (“EIS”) to allow for the recovery of carrying costs for capital expenditures associated with government-mandated environmental controls, subject to an existing cents per kWh cap on cost recovery that could produce up to approximately $5 million in revenues annually; |
• | Modifications to the Power Supply Adjustor (“PSA”), including the elimination of the 90/10 sharing provision; |
• | A limitation on the use of the RES surcharge and the Demand Side Management Adjustor Charge (“DSMAC”) to recoup capital expenditures not required under the terms of APS’s 2009 retail rate case settlement agreement (the “2009 Settlement Agreement”); |
• | Allowing a negative credit that existed in the PSA rate to continue until February 2013, rather than being reset on the anticipated July 1, 2012 rate effective date; |
• | Modification of the transmission cost adjustor (“TCA”) to streamline the process for future transmission-related rate changes; and |
• | Implementation of various changes to rate schedules, including the adoption of an experimental “buy-through” rate that could allow certain large commercial and industrial customers to select alternative sources of generation to be supplied by APS. |
