As described under Item 8.01 below, Arizona Public Service Company (“APS” or the “Company”) will be filing an application and related schedules for an annual increase in retail base rates with the Arizona Corporation Commission (the “ACC”) on June 1, 2016.  These materials will be posted on an APS website at www.azenergyfuture.com.  The information on this website is not incorporated by reference into this report. The ACC docket number is E-01345A-16-0036.

Item 8.01 Other Events.
 
Retail Rate Case Filing with the Arizona Corporation Commission
 
On June 1, 2016, APS will file an application with the ACC for an annual increase in retail base rates of $165.9 million. This amount excludes amounts that are currently collected on customer bills through adjustor mechanisms. The application requests that some of the balances in these adjustor accounts (aggregating to approximately $267.6 million as of December 31, 2015) be transferred into base rates through the ratemaking process. This transfer would not have an incremental effect on customer bills. The average annual customer bill impact of APS’s request is an increase of 5.74%.

The principal provisions of the application are:

a test year ended December 31, 2015, adjusted as described below;
         
an original cost rate base of $6.8 billion, which approximates the ACC-jurisdictional portion of the book value of utility assets, net of accumulated depreciation and other credits, as of December 31, 2015;

the following proposed capital structure and costs of capital:

a 1% return on the increment of fair value rate base above APS’s original cost rate base, as provided for by Arizona law;

a base rate for fuel and purchased power costs of $0.029882 per kilowatt-hour (“kWh”) based on estimated 2017 prices (a decrease from the current base fuel rate of $0.032071 per kWh);

authorization to defer for potential future recovery its share of the construction costs associated with installing selective catalytic reduction equipment at the Four Corners Power Plant (estimated at approximately $400 million in direct costs). APS will propose that the rates established in this rate case be increased through a step mechanism beginning in 2019 to reflect these deferred costs;






authorization to defer for potential future recovery in the Company’s next general rate case the construction costs APS incurs for its Ocotillo power plant modernization project, once the project reaches commercial operation. APS estimates the direct construction costs at approximately $500 million and that the new facility will be fully in service by early 2019;

authorization to defer until the Company’s next general rate case the increase or decrease in its Arizona property taxes attributable to tax rate changes after the date the rate application is adjudicated;

updates and modifications to four of APS’s adjustor mechanisms - the Power Supply Adjustor (“PSA”), the Lost Fixed Cost Recovery Mechanism (“LFCR”), the Transmission Cost Adjustor (“TCA”) and the Environmental Improvement Surcharge (“EIS”);

a number of proposed rate design changes for residential customers, including:
change the on-peak time of use period from 12 p.m. - 7 p.m. to 3 p.m. - 8 p.m. Monday through Friday, excluding holidays;
reduce the difference in the on- and off-peak energy price and lower all energy charges;
offer four rate plan options, three of which have demand charges and a fourth that is available to non-partial requirements customers using less than 600 kWh on average per month; and
modify the current net metering tariff to provide for a credit at the retail rate for the portion of generation by rooftop solar customers that offsets their own load, and for a credit for excess energy delivered to the grid at an export rate.

proposed rate design changes for commercial customers, including an aggregation rider that allows certain large customers to qualify for a reduced rate, an extra-high load factor rate schedule for certain customers, and an economic development rate offering for new loads meeting certain criteria.

The Company will request that the increase become effective July 1, 2017.  APS expects the ACC to issue a procedural schedule during the next sixty days detailing the timeline for addressing the application. APS cannot predict the outcome of its request.
