Program Costs include weatherization and bill assistance. Societal Costs do not include bill assistance because it does not contribute to electric savings. 2. Consistent with the ACC Staff’s analysis in Decision No. 68647, the societal benefit is equal to the societal cost, resulting in a benefit to cost ratio of 1.00 and net benefits of 0. 3. The ACC approved a revised Performance Incentive calculation in Decision No. 71448, on December 30, 2009, as follows. “The existing Performance Incentive shall be modified to be a tiered Performance Incentive as a % of net benefits, capped at a tiered % of program costs. 4. There were no new 2012 installations to report, and therefore, no incremental savings for Energy Information Services. However, the program remains cost effective based on on-going savings.

1. Program Costs include weatherization and bill assistance. Societal Costs do not include bill assistance because it does not contribute to electric savings. 2. Consistent with the ACC Staff’s analysis in Decision No. 68647, the societal benefit is equal to the societal cost, resulting in a benefit to cost ratio of 1.00 and net benefits of 0. 3. The ACC approved a revised Performance Incentive calculation in Decision No. 71448, on December 30, 2009, as follows. “The existing Performance Incentive shall be modified to be a tiered Performance Incentive as a % of net benefits, capped at a tiered % of program costs. 4. The Behavioral Program was cost effective in 2012, as evidenced above in Table 5. However, the PTD results includes start-up costs that will be offset over time with additional savings.

Page 11 of 99 PROGRAM: RESIDENTIAL EXISTING HOMES HVAC

Description The Residential Existing Homes Heating, Ventilation, and Air Conditioning Program (“Residential HVAC”) is divided into two distinct components, 1) HVAC measures and 2) Home Performance with ENERGY STAR ® (“HPwES”) measures.

The HVAC measures use a combination of financia l incentives, contractor training and consumer education to promote the proper installation and ma intenance of energy-efficient HVAC systems. The Air Conditioner (“AC”) Rebate, Duct Test and Repair and Residential Diagnostic measures support energy-efficient Residential air conditioning and heating systems along with the proper installation, maintenance and repair of these systems.

The HPwES measures promote a whole house approach to EE by offering incentives for improvements to the building envelope of existing Residential homes within the APS service territory. HPwES includes measures that improve the EE of the home with air sealing, insulation, shade screens, faucet aerators, and low flow showerheads.

Both components of the Residential Existing Homes HVAC program provide APS customers with referrals to contractors who meet strict program requirements for professional standards, technician training, and customer satisfaction.

The two components are discussed individually below:

a. HVAC Measures – AC Rebates, Duct Test and Repair and Residential Diagnostic The AC Rebate with Quality Installation (“QI”) measure offers financial incentives to homeowners for buying EE equipment (> 13 SEER/10.8 EER), that is installed in such a m anner that it meets the program requirements for air flow, refrigerant charge and sizing. The Duct Test and Repair (“DTR”) measure provides financial incentives to customers for having their HVAC system’s duct work tested for leakage and repaired. APS also has a pilot Resi dential Diagnostic measure to provide a financial incentive for an advanced diagnostic tune-up on existing air conditioning and heat pump equipment to ensure that it operates more efficiently. The main components of this measure are the correction of the refrigeration charge, leak repair, condenser coil cleaning and air flow verification.

In June 2006, APS implemented the AC Rebate measure. On A ugust 1, 2007, APS began offering the QI measure to optimize the installation of high-efficiency equipment that meets the AC Rebate measure requirements. This measure has high st andards on air conditioning sizing, airflow and refrigerant charge to ensure that when the equipment is installed, it will operate at a high level of efficiency.

On December 31, 2007, APS began the DTR measure which offers financial incentives to customers that test and, if necessary, repair the duct work in their homes.ARIZONA PUBLIC SERVICE COMPANY

DSM ANNUAL PROGRESS REPORT FOR THE PERIOD: JANUARY THROUGH DECEMBER 2012

Page 12 of 99 On April 7, 2009, the ACC approved the combination of the AC Rebate and QI measures along with revised incentive levels. See the January through June 2009 Semi-Annual Progress report for a detailed explanation.

On October 7, 2009, the ACC approved APS’s r equest to modify the contractor requirements to offer the AC Rebate and QI measures. See the July through December 2009 Semi-Annual report for a detailed explanation.

The Residential Diagnostic measure was approved as a Pilot on January 6, 2011 and it was launched on March 31, 2011.

Program Modifications Decision No. 73089, April 5, 2012 approved changes to the AC Rebate with QI. The rebate amount was changed to $270 for all SEER levels and EER of 10.8 or above. As of April 7, 2012 the rebate levels no longer varied by SEER levels and anything installed after this date received the $270 rebate if it complied with the other program requirements. The contractor rebate of $50 was also discontinued as of April 5, 2012. Program modifications for 2013, where applicable, are included in APS’s 2013 Implementation Plan.

Program Goals, Objectives and Savings Targets The HVAC component of the program uses a combination of financial incentives, contractor training and consumer education to promote high-efficiency HVAC systems, through the proper installation of this equipment, increasing existing equipment efficiency, and the testing and repair of the duct work in existing Residential homes within the APS service territory.

APS’s 2012 DSM Implementation Plan estimated that the EE savings expected to result from the HVAC portion of the program could reduce peak demand by approximately 14.0 MW, 19,000 MWh annually and 205,000 MWh over the life of the measures expected to be installed in 2012.

Programs or Measures Terminated No programs or measures were terminated during this Reporting Period. Programs or measures proposed for termination in 2013, where applicable, are included in APS’s 2013 Implementation Plan.

Levels of Participation

u A total of 13,999 rebates were paid through the HVAC portion of the program in 2012. APS has paid:

b. Home Performance with ENERGY STAR ® The HPwES program offers home owners a $99 comprehensive home energy checkup to help identify ways to improve EE and comfort throughout the home. This program element offers a direct install feature that includes up to 10 compact fluorescent lamps (“CFLs”), three faucet aerators, and one low-flow showerhead that are installed at the time of the checkup. Additional financial incentives are available for duct sealing, air sealing, insulation, and shade screens, once a home owner has completed an HPwES checkup. After measures are inst alled, rigorous test out and quality assurance protocols then verify installation quality and performance.

In January 2010, the ACC approved HPwES as a new measure under the Residential HVAC
program.

Program Modifications No significant program modifications were made to the HPwES program during this Reporting Period. Program modifications for 2013, where applicable, are included in APS’s 2013 Implementation Plan.

Program Goals, Objectives and Savings Targets The HPwES measures promote a whole house approa ch to EE by offering financial incentives for improvements to the building envelope of existing Residential homes within the APS service territory.

ACC Decision No. 71448 requires the APS HPwES measure to complete a minimum of 1,000 energy audits in 2010 and a total of 3,000 audits between 2010 and 2012. The program has completed 11,995 audits to date and has met both of these objectives.

Programs or Measures Terminated No programs or measures were terminated during this Reporting Period. Programs or measures proposed for termination in 2013, where applicable, are included in APS’s 2013 Implementation Plan.

Levels of Participation During this Reporting Period:

u A total of 7,357 contractor rebates were paid through HPwES for completed and approved energy audits. Each home that received a $99 home energy audit, also received a direct install bag containing 1 low-flow showerhead, 3 low-flow aerators and ten 13 watt compact florescent light bulbs.

u The APS HPwES program paid r ebates for measures installed in 2384 participating homes. This indicates that 32.4% of homes that completed an audit during the Reporting Period took steps to install additional measures as a result of the audit. The total number of customer rebates paid was 5,324, which averages abo ut two rebates per home. Specifically, APS has paid: a. 2,763 duct sealing and repair rebates.ARIZONA PUBLIC SERVICE COMPANY

These elements of the program produce additional energy savings and benefits that are not quantified.

Benefits and Net Benefits/Performance Incentive Calculation MER adjusted net benefits and performance incentive are provided in Tables 5 and 6.

Problems Encountered and Proposed Solutions Measure and evaluation results determined that the initial air tightness of participating homes was tighter than the original program baseline had estimated. This is primarily due to the average participating home having masonry walls or tradit ional wood framing and stucco, with the primary foundation type being slab on grade. This construction style is tighter than we estimated and thus did not yield the air leakage reduction expected. This condition is reflected in the MER result for this reporting period.

To improve the air sealing measure cost effectiveness, APS pr oposed to set an existing leakiness threshold for air sealing rebate eligibility. Effective March 1, 2013, a participating home must have an existing leakiness of 16 ACH 50 in order to quality for an air sealing incentive.

Due to measure and evaluation received in early 2012, APS deci ded not to launch the performance based rebate measure for HPwES approve in Commission Decision No. 73089. The funding for this measure was shifted to the existing prescriptive measures in the HPwES program. The performance based rebate measure will not be included in the 2013 Implementation Plan.

Page 20 of 99 PROGRAM: RESIDENTIAL NEW HOME CONSTRUCTION

Description This program promotes high-efficiency construction practices for new homes. It offers incentives to builders that meet the program’s EE standards. The program emphasizes the whole building approach to improving EE and includes field testin g of homes to ensure performance. Participating builders are trained to apply building science principles to assure that high-efficiency homes also have superior comfort and performance. The program also provides education for prospective homebuyers about the benefits of choosing an energy-efficient home and the features to consider.

The program takes advantage of the national ENERGY STAR ® brand name, and promotes the EPA ENERGY STAR ® label to prospective homebuyers. To encourage builders to meet the program’s high-efficiency standards, APS provides builder incentives of $1,000 per home for ENERGY STAR version 3 compliant homes. To encourage builders to meet even higher EE standards, the program also offers a second tier incentive of $1,500 per home for builders that meet the higher savings level of Home Rating Energy System (“HERS”) 60.

Program Modifications Beginning January 1 st , 2012 the National ENERGY STAR Homes Program introduce Version 3, which increases that minimum efficiency standards for ENERGY STAR certified homes. As approved in Commission Decision No. 73089, APS introduced two new builder incentives, replacing the Version 2 incentives, for Version 3 and a higher tier Version 3 – HERS 60, to align with the changes in the national program.

APS did not receive approval for the new incentives until April 5 th , 2012. In an effort to support our builder partners, Incentives processed between Jan. 1st and April 4 th , 2012 were completed under Version 2 incentives approved for the 2011 program year. The change of incentives mid-year is reflected in the reporting for this period.

Program modifications for 2013, where applicable, are included in APS’s 2013 Implementation Plan.

Program Goals, Objectives and Savings Targets The program objective is to increase the penetration of homes built to high-efficiency standards. The rationale for this program is that Residential new construction in the APS service territory, particularly the Phoenix metro area, has historically been one of the biggest drivers of APS’s system load growth. It is more cost-effective to work with builders to implement EE at the time of construction rather than to attempt to retrofit efficiency after a home has been built. For many new home measures, such as building envelope improvements, the benefits of EE upgrades will be sustained for the life of the home to produce cost-effective savings.

APS’s analysis of this program, as filed in the 2012 APS DSM Implementation Plan, estimates that the EE savings expected to result from the Residential New Construction Program in 2012 couldARIZONA PUBLIC SERVICE COMPANY

Programs or Measures Terminated No programs or measures were terminated during this Reporting Period. Programs or measures proposed for termination in 2013, where applicable, are included in APS’s 2013 Implementation Plan.

Levels of Participation During this Reporting Period, APS signed up 10, 452 homes that are committed to being built to ENERGY STAR ® V3 program standards and to being built to the ENERGY STAR ® V3 – HERS 60 program standards. This growth in signed homes is a strong indicator that new home market is beginning to recover. At the end of this Reporting Period, there were 42 homebuilders and 160 subdivisions currently participating. The program currently includes ENERGY STAR ® communities throughout the APS service territory including the Phoenix metro area, Yuma, Casa Grande, Florence, Prescott, Verde Valley, and Flagstaff.

APS paid a total of 2, 737 homebuilder incentives and 2,015 $50 rater incentives during the reporting period. Specifically, APS has paid:

u 151 ENERGY STAR Home – January – April 2011

u 571 ENERGY STAR Tier 2 (HERS 70) – January – April 2011

u 1,913 ENERGY STAR Version 3

u 102 ENERGY STAR Version 3 – HERS 60

Since the start of this program in 2006, APS has paid incentives on 12, 065 ENERGY STAR ® homes.

During this Reporting Period, APS held 5 builder trainings. The training, called “Success with ENERGY STAR ® ”, teaches builders and their subcontrac tors about techniques for improving construction details that impact efficiency and that allow the home to pass ENERGY STAR ® inspections. The training includes detailed customized construction photos and process checklists to ensure implementation accuracy at the job site. In addition, APS provided sales training and/or technical training assistance to numerous Arizona builders during this Reporting Period.

Other Significant Information In recognition of the ongoing success of the APS EE program portfolio and the APS ENERGY STAR ® Homes and Home Performance with ENERGY STAR Programs, APS was selected by the U.S. EPA as a 2012 ENERGY STAR ® Partner of the Year, Sustained Excellence Award winner. This is the highest award that can be earned by an ENERGY STAR ® partner, and is bestowed on partners who show sustained excellence in their commitment to EE and whose organization is a national model of best practices in advancing EE. APS has now earned ENERGY STAR ® awards for seven consecutive years.

In a 2012 report released by the U.S. Environmental Protection Agency, Arizona was identified as having the greatest market share in the country for ENERGY STAR Certified new homes. This metric reflect the success of the APS ENERGY STAR Homes program and the strength of you builder and rater partners.

In September, APS was the presenting sponsor and key contributor to the national Energy Efficient Building Alliance conference, held in Scottsdale. APS br ought in trainers from the ENERGY STAR homes program staff and Advanced Energy to devel op and present specific ENERGY STAR breakout sessions for builders, including “Success with ENERGY STAR ,” “Success with Cathedralized Attics,” “HVAC for ENERGY STAR V 3.0,” and “Why ENERGY STAR.” APS also coordinated and helped present workshops on green appraisals, building codes and more. The event was attended by many local and regional builders - APS provi ded partial scholarships for 24 participating ENERGY STAR builders.

In April 2012, APS official launc hed a new program database as provided by Pivotal Energy Solutions. With this new database, raters can now directly submit the more robust ENERGY STAR Version 3 compliance documentation through an online portal. This new software will improve incentive processing efficiency, provide better reporting capabilities, and collect more comprehensive data on participating homes. APS is currently working on extending the user functionality beyond raters, to our builder partners.

Program marketing and education efforts during this Reporting Period include the following:

u Television – APS developed and aired a new ENERGY STAR homes TV ad in 2012. The ad aired on local news and sports broadcasts, including Phoenix Suns NBA games and Arizona Diamondbacks baseball games. The simple ad touts the energy savings and benefits of ENERGY STAR homes.

Page 25 of 99 PROGRAM: CONSUMER PRODUCTS PROGRAM

Description The Consumer Products Program is composed of two components – Residential Lighting and Residential Pool Products.

The Residential Lighting element of the program promotes high-efficiency EPA/DOE ENERGY STAR ® CFLs. CFLs use an average of 75% less e nergy than standard incandescent bulbs and last up to ten times longer, typically saving consumers up to $40 in energy costs over the life of each bulb. The program offers discounts on CFLs through cooperative agreements with retailers and lighting manufacturers. This provides consumers with reduced re tail prices for CFLs at local lighting retailers, with prices typically at or below $0.99 per bulb for standard 60 watt equivalent CFLs.

The Energy-Efficient Pool Pump and Timer element of the Consumer Products program is designed to improve the EE in Residential pool operations while maintaining equivalent or better standards for pool sanitation and cleanliness. The program promotes the installation and optimal calibration of energy-efficient variable -speed pool pump motors and seasonal timers with rebates ranging from $75 to $270.

Program Modifications A.R.S. § 44-1375 (“Title 44”) includes Arizona legislation that went into effect on January 1, 2012 which mandates that pool pumps sold in Arizona must have a minimum of two speeds with an accompanying controller capable of toggling between speeds, thereby eliminating the sale of singlespeed pool pumps as primary filtration systems on standard pools. As a result, it was not necessary to continue to rebate dual speed pool pumps since that is now the minimum required to be compliant with the statute.

Another modification to one of the measures within the Pool Pump and Timer program proposed during this Reporting Period was to suspend offering $75 rebates on seasonal timers. After the issuance of Commission Decision No. 73809, the only company which manufactured the “seasonally adjusted” Pool Timers as part of APS’s Consumer Pr oducts Program went out of business. This has left the market without a widely distributed product that meets the current APS program guidelines, and consequently program participation in 2012 was very low with only seven units rebated to customers. Therefore, sufficient participation data was not available to conduct research regarding the cost effectiveness of the measure.

Because there are currently no opportunities for customers to purchase qualifying timers, APS has proposed not including pool timers as an eligible measure for 2013. If a new product becomes available which meets APS’s program guidelines, APS may seek to reinstate the measure as part of a future DSM Implementation Plan filing.

Program modifications for 2013, where applicable, are included in APS’s 2013 Implementation Plan.ARIZONA PUBLIC SERVICE COMPANY

DSM ANNUAL PROGRESS REPORT FOR THE PERIOD: JANUARY THROUGH DECEMBER 2012

Page 26 of 99 Program Goals, Objectives and Savings Targets For the CFL element of the program, the goal is to promote the purchase of high-efficiency CFLs and increase the awareness and knowledge of retailers and consumers on the benefits of ENERGY STAR ® rated lighting products

.
For the energy-efficient pools element of the program, the goal is to promote the purchase of highefficiency variable-speed pool pumps and seasonal pool timers. In a typical Arizona home with a pool, the pool pump energy use can make up a signific ant portion of annual energy use, often second after heating and cooling costs.

APS’s analysis of the overall Consumer Products program, including both the CFL and pools elements of the program, estimates that the EE savings expected to result from the program could reduce peak demand by about 13.0 MW and reduce e nergy consumption by 696,000 MWh over the life of the measures expected to be installed in 2012.

Programs or Measures Terminated No programs or measures were terminated during this Reporting Period. Programs or measures proposed for termination in 2013, where applicable, are included in APS’s 2013 Implementation Plan.

Levels of Participation During this Reporting Period, the energy-efficient lighting element of the program resulted in sales of 2,651,802 CFLs through participating retail locations. In addition, APS distributed 121,579 CFLs during community events and consumer education seminars, for a combined total of 2,773,381 CFLs distributed during 2012. There were also approximately 325 retail outlets participating throughout the APS service territory where APS customers could purchase discounted CFLs. Participating retailers during this Reporting Period included: 99 Cents, Ace Hardware, Batteries Plus, Big Lots, Costco, Dollar Tree, Goodwill Industries, Home Depot, Lighting Unlimited, Lowe’s, Sam’s Club, True Value, and Wal-Mart.

The pool pump and timers element of the program received approval in January, 2010. The program currently includes 213 participating pool retailers, distributors, and pool builders. During this Reporting Period, a number of pump calibration training seminars were held with a total of more than 83 pool professionals trained. In addition, program representatives attended pool industry association meetings and conducted retail visits to inform pool professionals about the APS rebate
program.

During this Reporting Period, the program provided rebates for 3,858 variable speed pool pumps, and 7 seasonal pool timers.ARIZONA PUBLIC SERVICE COMPANY

Other Significant Information APS continued a CFL recycling program in partnership with participating retailers and Veolia Environmental Services, which operates a recycling facility in Phoenix. Customers can take their burned out CFLs to participating retail locations (including select Ace, True Value and Home Depot stores) throughout the APS service territory for free recycling. Retailers collect the CFLs and then send them to Veolia, where more than 99% of all materials, including the trace amounts of mercury in CFLs, are reused.

The program conducted retailer visits and retailer trainings during the Reporting Period to educate retail sales staff, assess inventories of merchandise, check point of purchase displays, address availability of qualified product, and communicate with retail sales staff.

In addition to the bulb sales at retail locations, APS has purchased a supply of CFLs to use for the low income program and for customer education and awareness building purposes. APS uses these bulbs for direct installation through the APS Low Income Weatherization program (two bulbs provided for each home that is weatherized) and to hand out at local community events and other opportunities to educate the public about CFLs.

APS c onducted 183 community education and customer outr each events during this reporting period to promote the CFL program and educate customers about APS programs, rebates, and opportunities for saving energy and money. For a comprehensive list of events and dates, please refer to the workpapers provided to ACC Staff.ARIZONA PUBLIC SERVICE COMPANY

Page 33 of 99 PROGRAM: REFRIGERATOR RECYCLING PROGRAM

Description The program is designed to educate APS customers that their old, operating, extra refrigerator or freezer uses a great deal of energy and that by tu rning it in, they can save up to $100 per year on their electric bill. Many refrigerators and freezers being replaced are still functioning and often end up as secondary units in basements and garages, or are sold in the used appliance market. This program provides customers an incentive to remove their old, inefficient appliances from the grid.

APS customers with an old operating extra refrigerator can receive a $30 rebate with free pick up service at the customers’ convenience that can be scheduled either online at aps.com/turnitin or by calling toll free 877-514-6654. APS partners with JACO Environmental, Inc. to provide the free pick up and recycling service.

The APS Refrigerator Recycling Program began on February 1, 2010. This program was approved by Decision No. 71444, December 23, 2009. The primary focus for 2012 has been on program awareness and marketing. The marketing strategy emphasizes education to the customer about the inefficiency of their second working refrigerator or freezer, the $30 rebate, and the free pickup service provided.

As a result of creating this program, a recycling facility has been established in Phoenix where up to 95% of appliance elements are recycled and used to manufacture other products. Additionally, 20 new “green” jobs have been created to staff and operate the new recycling facility. During the recycling process, JACO Environmental safely dis poses of all refrigerators and freezers preventing the release of hazardous chemicals into the environment.

Program Eligibility Requirements:

u Must be a current APS customer and the unit must be owned by customer.

u Refrigerator/freezer must be operab le (maintain a cold temperature).

u Refrigerator/freezer must be plugged in (cold inside) and empty.

u Refrigerator/freezer must be a standard size (between 10 – 30 cubic feet).

u There must be a clear pathway to pick up and remove appliance.

u There is a maximum of two units per household per year.

u Someone 18 years or older must be present to sign and release unit.

Program Modifications No program or measures were modified during this Reporting Period. Program modifications for 2013, where applicable, are included in APS’s 2013 Implementation Plan.

Program Goals, Objectives and Savings Targets The program objective is to educate APS customers that their second, older, working refrigerator or freezer in the garage or laundry room is costing them an additional $100 per year in energy costs toARIZONA PUBLIC SERVICE COMPANY

DSM ANNUAL PROGRESS REPORT FOR THE PERIOD: JANUARY THROUGH DECEMBER 2012

Page 34 of 99 operate. Refrigerators and freezers today are much more energy-efficient than models built prior to 1993,and models sold today use about 1/3 the energy of older units.

The 2012 program goal was to recycle 9,700 units with approximately 14,700 MWhs saved. In this reporting period, 9,464 units were recycled resulting in EE savings that reduce peak demand by approximately 2.1 MWs and saving 71,241 lifetime MWhs.

Programs or Measures Terminated No programs/measures were terminated during this Reporting Period. Programs or measures proposed for termination in 2013, where applicable, are included in APS’s 2013 Implementation Plan.

Levels of Participation During this Reporting Period, APS recycled 9, 464 refrigerators and freezers, and paid $284,002 in incentives to customers. Units were picked up across APS’s service territory statewide. Year-end volume totals came in at 98% of target, which was very close to the 9,700 unit goal.

JACO Environmental entered into a partnership wi th Sears in November 2010. The purpose of the agreement was to add value and convenience to customers when they purchase a new refrigerator or freezer. At the point of sale, the customer will receive a special sticker to place on their old unit providing the ability to track APS retail units s eparately.

Upon delivery of a new refrigerator or freezer, Sears will pick up the customer’s old (now secondary) appliance, saving them the hassle of making another appointment to schedule a refrigerator recycling pickup. This ensures that the old unit does not end up in the secondary market, or a garage or laundry room plugged in. The customer receives the $30 rebate from JACO through normal operating channels. These units are taken to a Sears containment facility where JACO picks up the stickered refrigerators and freezers once a week fo r recycling and processing. During this Reporting Period, APS recycled 674 units picked up through Sears.

Evaluation and Monitoring Activities and Results

u Continued to review and update program Measure Analysis Spreadsheets and the Analytic Database.

u Provided guidance on Appliance Recycling Program components in the design tool to support the implementation plan.

u Continued review of the implementation program tracking database.

u Completed research to determine customer satisfaction, hours of use, and process improvements

Page 37 of 99 PROGRAM: BEHAVIORAL PROGRAM

Description The Residential Conservation Behavior Pilot Program provides participating Residential customers with bi-monthly reports containing information designed to motivate them to change their energy usage behavior to save energy.

To drive conservation behavior, this program direct mails comparative Home Energy Reports to Pilot participants that show how the energy usage in that customer’s home compares with similar homes. Coupled with the comparison data, customers receive recommendations for specific and targeted actions they can take to save energy.

Derived from best practices in behavioral science re search, this program uses the power of normative messaging to successfully engage and motivate conservation actions of targeted individuals. Comparing an individual’s energy use to what is “normal” has proven to be an effective mechanism to attract attention and motivate action. Normative messaging on energy use, combined with recommendations on how to improve, is the basis of the concept for the Conservation Behavior program. The program provides a benchmark for cu stomers to achieve, and instills a sense of competition to produce sustained conservation behaviors.

Program Modifications There were no program modifications to report this Reporting Period.

In 2013, APS plans to c hange all similar home language reports to neighbor language to increase program saving’s potential by as much as 0.5% with no additional cost and minimal impact to report recipients. Program modifications for 2013, where applicable, are included in APS’s 2013 Implementation Plan.

Program Goals, Objectives and Savings Targets The goal of this Program is to use scientifically proven normative messaging techniques to motivate Program participants to save energy by changing their energy use behavior.

APS’s 2012 DSM Implementation Plan estimated that the EE savings from the Behavioral Program could reduce peak demand by approximately 4.3 MW and save 31,000 annual MWh. Actual results indicate 3.9 MW and 23,543 MWh saved in this Reporting Period.

Programs or Measures Terminated No programs or measures were terminated during this Reporting Period. Programs or measures proposed for termination in 2013, where applicable, are included in APS’s 2013 Implementation Plan.ARIZONA PUBLIC SERVICE COMPANY

Page 40 of 99 PROGRAM: MULTIFAMILY ENERGY-EFFICIENCY PROGRAM

Description The Multifamily Energy Efficiency Program (“ME EP”) is a program that encourages EE improvements in multifamily complexes within the APS service territory. The MEEP received ACC approval on January 6, 2012 in Decision No. 72060.

MEEP uses a three-track approach to promote EE within the multifamily market segment.

u Track 1 provides free direct install components to retrofit the Residential dwellings of existing communities. Participating communities will receive enough CFLs, low flow showerheads, and faucet aerators to retrofit ev ery community dwelling. Facility personnel, with implementation contractor field support, will conduct all direct install installations.

u Track 2 will utilize APS Solutions for Business programs to provide complementary energy assessments of the community commercial facilities. The energy assessment will identify opportunities for additional EE savings and the applicable Solutions for Business incentives that are available.

u Track 3 targets new construction and major r enovation multifamily projects. This track builds from the success of the APS ENERGY STAR ® Homes program and encourages energy efficient building principles by paying an incentive to builders on a per unit basis for following a list of EE measures outlined in one of four builder option packages (“BOP”).

u Larger incentives are offered for achieving increasingly higher levels of EE.

Program Modifications A redesigned M EEP new construction program was introduced in 2 012. The redesign included a new BOP structure that featured a prescriptive path with both mandatory and optional measures as well as a performance path that utilizes Home Energy Rati ng System (HERS) Scores to achieve compliance. The new BOPs and compliance paths were designed to provide builders and developers flexibility in meeting program requirements. Program modifications for 2013, where applicable, are included in APS’s 2013 Implementation Plan.

Program Objectives, Goals and Savings Targets The MEEP program objectives are to:

u Reduce peak demand and overall energy consumpt ion in the multifamily housing market segment.

u Promote existing community EE retrofits of both dwelling units and common areas.

u Promote higher efficiency construction standards in the development of new multifamily projects.ARIZONA PUBLIC SERVICE COMPANY

u Decision No. 68647 acknowledged the estimates that the Weatherization component of the Energy Wise Program could serve 382 homes per year (based on APS’s annual budget of $705,000) and result in reduced energy consumption of 763 MWh per year and a demand reduction of 115 kW per year.

The goals for the APS Energy Wise Low Income Weatherization program specified in APS’s 2012 DSM Implementation Plan estimates that the EE savings expected to result from the Low Income Program could reduce peak demand by about 0.2 MW and 30,000 MWh over the life of the measures expected to be installed.

Programs or Measures Terminated No programs or measures were terminated during this Reporting Period. Programs or measures proposed for termination in 2013, where applicable, are included in APS’s 2013 Implementation Plan.ARIZONA PUBLIC SERVICE COMPANY

Evaluation and Monitoring Activities and Results Weatherization measures must pass the cost effectiveness test that is detailed in the federal government's Weatherization Assistance Program (WAP) rules. These rules allow certain prescriptive measures, which vary with the climate zone and type of housing constructi on. Measures not on the prescriptive list must be assessed by a computer analysis to determine the economic feasibility.

The Arizona Governor’s Office of Energy Policy (“GOEP”), with information from APS, is analyzing the electric energy used in weatherized homes before and after the weatherization measures are implemented. It takes a year of data before the weatherization and another year of data after the weatherization to get an accurate gauge of the impact of the measures. As the data base grows over time, a more accurate picture of the impact of the weatherization activities will emerge.

Information from the GOEP report for fiscal year 2012, submitted January 2013 is provided below:

Utility Bill Analysis An analysis of 257 homes has been completed from July 2007 through July 2012, utilizing APS, Tucson Electric Power, Unisource Gas and Electric and Southwest Gas utility data. This analysis is ongoing, new data will be updated to these values on a quarterly basis.

Provided are Savings to Investment Ratios (“SIR”) for total investment from all funding spent (diagnostics, energy measures and heal th and safety measures) and for energy related measures only (diagnostics and energy measures).

Assumptions Present value is based on 17.5 years measure life, discount rate of 3% and a utility cost escalation rate of 3%.

Results Summary The combined SIR of all jobs reviewed to date for funds spent on diagnostics, energy measures and health and safety measures was 1.21. Health and Safety represented 16% of expenditures.ARIZONA PUBLIC SERVICE COMPANY

DSM ANNUAL PROGRESS REPORT FOR THE PERIOD: JANUARY THROUGH DECEMBER 2012

Page 49 of 99 The combined SIR of all jobs reviewed to date for funds spent on energy measures and diagnostics was 1.38.

The average saving per home reviewed was 2,746 kWh and 35 therms of natural gas (gas therms average includes all electric homes).

MER Adjusted Gross kW and kWh Savings Of the 1,474 households participating in the program, a total of 852 homes received weatherization services that contributed to the energy savings.

No. of Homes Annual kW Savings Annual kWh Savings Lifetime kWh Savings 852 286 2,503,363 43,808,860 MER savings are adjusted for line losses (energy 7.0%, demand 11.7%) and a capacity reserve factor of 15%.

The kW factor used to calculate the savings are based on data from the Arizona Energy Office study of 257 weatherized homes. The study normalized elec tric and gas savings into dollars with gas savings equaling about 10% of the total. The present value of the dollar savings was converted to “equivalent kWh” at 8 cents per kWh. The annual energy demand savings per home in this study are estimated to be 0.3 kW. A 17.5 years measure life and kWh savings factor of 2746 kWh per home, based on the current GOEP report, has been utilized to determine the appropriate kWh savings.

Benefits and Net Benefits/Performance Incentive Calculation The net benefits for this program are provided in Tables 5, and 6. The Performance Incentive calculation does not include the Energy Wise Program because, as indicated in Decision No. 68647, this program has a zero net benefit. Consequently, the net benefits for the Energy Wise Program for this Reporting Period as shown in Table 5 are $0. However, the spending on the Energy Wise Low Income Weatherization Program is included in the total spending, on which the performance incentive is calculated.

Problems Encountered and Proposed Solutions The American Recovery and Renewal Act (“ARRA”) weatherization funding impacted the APS Energy Wise Weatherization program up until March when the program ended. The temporary slowdown in utility weatherization program activities was a direct result of the agencies focus on spending the ARRA funds before March. Nonetheless, the agencies were able to expend most of the funding by year end.ARIZONA PUBLIC SERVICE COMPANY

Page 51 of 99 PROGRAM: NON-RESIDENTIAL PROGRAM FOR LARGE EXISTING FACILITIES

Description The Large Existing Facilities Program provides pr escriptive incentives for owners and operators of large (over 100 kW aggregated peak monthly demand) Non-Residential facilities for EE improvements in technologies such as lighting, HVAC, motors and refrigeration applications. The Direct Install approach is available for facilities which are individually metered with a peak demand of 400 kW and less. For EE applications not covered by the prescriptive incentives, the program offers custom incentives, which are evaluated individually based on energy savings. The program also provides incentives to reduce the cost of an energy study that identifies energy saving opportunities. The program provides educational and promotional pieces designed to assist facility and business owners and operators in making decisions to improve the EE of their facilities.

Large Existing – Studies $380,623
Large Existing – Retro commissioning Studies $311,700 Total Large Existing Funds $17,245,333

In Decision No. 70637, the ACC approved APS’s request to continue to track DSM applications resulting from studies for which incentives have been paid, and to report the semi-annual and cumulative results of its program-to-date. During this Reporting Period, APS paid a total of $692,323 for 96 study applications from 34 customers. During this reporting period, sixty-eight feasibility studies were paid a total of $378,723, twelve benchmarking studies were paid a total of $1,900, and sixteen retro commissioning studies were paid a total incentive of $311,700. Forty-eight of the 96 studies have already resulted in implementation of the associated measures. Since the program’s inception, 283 studies have been completed. Of those 283 studies, 137 have resulted in EE project applications to date.

Decision No. 73089, required APS to report the type of measures installed by customers after a study was completed. The following measures were installed for studies completed in 2012: chillers, economizers, HVAC, HVAC controls, interior lighting, motors, programmable thermostats and refrigeration.

Self-Direction: On January 23, 2009, the Commission issued Decision No. 71444, which approved Self-Direction.

In this Reporting Period one (1) customer participated in Self Direction. The project included the conversion of existing exterior mercury vapor lighting and exterior incandescent lighting to LED lighting on the following mechanical mining shovels: #8, #10, #11, #21, and #22. Shovel #8 included the conversion of interior fluorescent lighting to LED lighting as well.ARIZONA PUBLIC SERVICE COMPANY

DSM ANNUAL PROGRESS REPORT FOR THE PERIOD: JANUARY THROUGH DECEMBER 2012

Page 55 of 99 The total cost of this phase of the project was $107,311.53. Since this change out was done solely for the purpose of saving kWh’s and did not need to be changed out due to a replace on burnout situation, the incremental cost of the project is equivalent to the project cost.

Trade Ally Network: Trade allies are contractors and other industry professionals who deliver EE solutions to customers. The program incorporates a Trade Ally program to ensure an informed and engaged network of service providers. To be listed as a Solutions for Business Trade Ally, a company must submit an application and attend program training which includes prescriptive application instruction. To remain on the list, the company must participate in the rebate program and attend an annual training.

As a result of the program’s focus on trade ally development and recruiting efforts, 16 new trade allies (companies) were approved during this Reporting Period; 59 were dropped for lack of participation. At the end of this Reporting Period the program had a total of 266 trade allies (companies).

Trade Ally Outreach The Trade Ally program continues to generate interest from a variety of industry professionals. These professionals must attend a training session to learn about the Solutions for Business program and the benefits of becoming a program trade ally. This meeting is offered free of charge, as is prescriptive application training, custom application training and meetings to assist with application preparation. Trade Ally Orientations were suspended for the last quarter of this reporting period.

Outreach is conducted through strate gic partnerships with professional associations within the energy and contracting industry as well as trade show and event participation and program advertisements. These efforts were scaled back during 2012 to concentrate on high quality participants.

Program trade allies received two editions of the Solutions for Business Trade Ally Newsletter during this Reporting Period. Newsletter articles provided program updates, links to useful program information and information on upcoming events and training opportunities.

Additional trade ally development opportunities centered on technical support to new and existing trade allies with an enhanced focus on encouraging program participation, increasing program knowledge and improving the quality of incentive applications submitted by trade allies.

2. Customer Awareness and Advertising: Marketing and outreach efforts focused on high-value opportunities to raise customer awareness of the program and EE benefits. To accomplish these goals, a variety of marketing tools and channels were used to reach customers and contractors, including print and electronic advertisements, updates to the program website, public relations events and print materials.

u Messaging in print advertisements placed during this Reporting Period included:

o Two ads ran in the Phoenix Business Journal featuring messages of appreciation to 2011 participating contractors and to the winners of the 2012 Trade Ally program awards in August.

o A shared message promoting HVAC tune-ups for both commercial and residential customers ran in the ACCA product directory in May/June.

o Electronic banner ads in the Phoenix Business Journal website ran from August through November promoting the message of EE to a wide audience of businesses and customers.

o An ad was placed in the AZRE Magazine in March/April congratulating nominees of the annual RED (Real Estate Development) awards and recognizing the winner of the APS sustainability award.

u Sponsorship of the annual RED awards helped raise awareness in the program and promote EE to the construction and real estate industries thro ugh sponsorship of the “most sustainable” project and presentation of annual program highlights during the event to an attendance of more than 400.

u The May APS Success newsletter featured articles developed to promote the nonresi dential program to customers receiving the newsletter with their bills.

u Trade allies received program information and updates in two e-newsletters produced and distributed in June and October.

u Program incentives were submitted in July to the ENERGY STAR ® Commercial Kitchen Guide for inclusion in online site listings.

u Large checks were produced and printed for presentations to recognize participation and help raise awareness of the program at customer events in 2012 including: the city of Yuma and eBay (July), Somerton Elementary School District (A ugust), the city of Tempe (November) and the Town of Buckeye and Dick’s Sporting Goods (December).

u The annual Arizona Highways calendars project began in October and involved developing artwork promoting the program for the back p anel of the calendars and distribution of the calendars to 200 members of the Trade Ally program; APS coordinated distribution of the calendars to more than 900 participating contractors.ARIZONA PUBLIC SERVICE COMPANY

DSM ANNUAL PROGRESS REPORT FOR THE PERIOD: JANUARY THROUGH DECEMBER 2012

Page 60 of 99 u Electronic invitations went out to participating customers, contractors and members of the Trade Ally program promoting training workshops and events, and encouraging attendance throughout the year.

u Program marketing materials and event display items were rebranded in 2012 to bring the print collateral and exhibit materials into compliance with new APS br and standards.

u Poster-size case study displays were developed promoting energy savings by business type (K12, data centers, office buildings and retail) used at events throughout the year.

u A new case study promoting incentives for LED lighting for the retail market was developed.

Market Segmentation APS conti nues to tailor its marketing and outreach efforts to specific market segments. As a program matures and “early adopters” complete projects, it becomes more challenging to engage participants and achieve energy saving targets. By segmenting the Non-Residential market into more-defined categories, the program can implement targeted and cost-effective strategies to engage customers. The objective is to secure participation by a broader range of eligible customers and to encourage these customers to implement comprehensive projects beneficial to their specific business.

The program currently segments Non-Residential customers into 12 categories by business type: college/universities, data centers, government, grocery, hotels, industrial, K-12 schools, medical, office, restaurant, retail and warehouse. The segments align with customer participation trends and demographics.

During this Reporting Period, one outreach and one technical staff were assigned to each segment. Each person supports three to four different s egments. The assigned staff will provide in-depth knowledge of their particular segments in terms of segment motivators, barriers, procurement process, energy consumption patterns, and appropri ate technologies and energy-saving measures. Outreach staff will continue to develop relationships with associations and other industry contacts related to the assigned segments, participate in events and guide development of marketing messages and program tools.

Each market segment has an individual savings goal and outreach plan based on historical and current participation, potential, and other market conditions. This will allow APS to better track success within segments and quickly adjust for changing market conditions and opportunities pertaining to these segments.

3. Generate Program Awareness Through Key Events : The program participated in the following trade shows and conferences:

4. Technical Training: Training courses help customers understand technologies and potential for energy savings. This understanding promotes quicker adoption of new technologies and encourages customers to undertake more in-depth and holistic projects . Classes allow interaction among customers, topic experts and contractors who can perform work, thus facilitating the contracting process. Feedback from this educational series indicates that customers are more likely to adopt alternative technology following such presentations and the knowledge gained from them.

APS conti nued to work closely with the Arizona Chapter of the Association of Energy Engineers (“AEE-AZ”) to promote and m anage registration of the APS Technical Training series. AEE-AZ provided access to their membership to promote t he trainings and the Solutions for Business program and also provided APS with turnkey registration su pport for the two trainings that occurred during this Reporting Period. Attendance remained strong during this Reporting Period with many repeat attendees.

The classes held during this Reporting Period attracted 234 attendees:

u January 25/26 – Motor Systems Management (66 attendees)

Page 82 of 99 PROGRAM: ENERGY INFORMATION SERVICES (“EIS”) PROGRAM

Description The EIS Program, which was first made available to APS customers in November 2006, helps large customers (>100 kW) save energy by giving them a better understanding and control of their facilities’ electric use. EIS provides data not only re garding usage and demand, but also identifies when, where and how much power is used in specific areas of each facility. This detailed information allows customers to fine-tune equipment use and operations and to document the impact of those changes. Participating customers monitor their electric usage through a web-based energy information system that allows them to receive historical (up to previous day) 15-minute usage and demand graphics. This information can be used to improve or moni tor energy usage patterns, reduce energy use, reduce demands during on-peak periods and better manage overall energy operations.

APS is encouraging customers to take advant age of EIS by providing a one-time incentive of up to a maximum of $12,000 or 75% of the cost of installing metering and communications equipment necessary to participate in the program.

Program Modifications No modifications were made during this Reporting Period. Program modifications for 2013, where applicable, are included in APS’s 2013 Implementation Plan.

Program Goals, Objectives and Savings Targets

u Provide monthly energy usage information to participating large Non-Residential customers.

u Participants identify strategies to lower energy cost by reducing energy usage and demand.

u Educate EIS program participants about utility rate concepts and how managing or reducing their energy consumption through EE measures and operational practices can reduce their
energy expenses.

u Teach participants how to download billing history information and create spreadsheets to chart and graph their energy use, as well as to identify consumption trends and savings opportunities.

u Educate EIS participants about creating reports for management that justify energy-efficient capital expenses intended to produce operations and maintenance savings; and

u Facilitate analysis of what-if scenarios to help large facility managers assess the benefits of capital improvements or operating adjustments to improve EE.

u Customers ultimately save electric (kWh) energy through simple changes in operations and maintenance (low/no cost savings measures).

Programs or Measures Terminated No programs or measures were terminated during this Reporting Period. Programs or measures proposed for termination in 2013, where applicable, are included in APS’s 2013 Implementation Plan.ARIZONA PUBLIC SERVICE COMPANY

Page 91 of 99 PROGRAM: TIME OF USE (“TOU”) RATES INCLUDING SUPER PEAK PRICING (“SPP”)

Description TOU rates are designed 1) to reflect the time variation in the cost of producing electricity, to more accurately match those costs with the service bei ng provided to the customer thereby encouraging efficient use of energy, and 2) to encourage cust omers to reduce consumption during peak hours or to shift energy usage to off-peak periods.

APS currently offers five Residential TOU rates: a. Two "Series 1" rates that have on-peak hours from 9:00 a.m. to 9:00 p.m. and have been offered since 1982. The Series 1 rates were closed to new customers on January 1, 2010, b. Two “Series 2” rates that have on-peak hours from 12:00 pm Noon to 7:00 p.m. and have been offered since 2006. These rates offer customers 40% fewer on-peak hours, c. One Super-Peak Pricing TOU rate that went into effect on January 1, 2010. The SPP periods are pre-determined and set forth in the rate schedule rather than communicated to the customer on a day-ahead basis as with the CPP. Participating customers will pay higher charges during the "Super-Peak" periods, but will pay lower charges during off-peak periods. The "Super-Peak" period is 3:00 p.m. to 6:00 p.m., Monday thru Friday during June, July, and August (excluding holidays).

APS is offering two new sc hool rates which contain an additional shoulder time period which may benefit customers who can shift loads from on-peak times.

Rate Modifications No modifications have occurred in the rates.

Levels of Participation Approximately 534,000 customers are enrolled in the TOU rates of which 640 are super peak customers. As of December 2012, five schools were enrolled in the new school rates.

MW and MWh Savings Targets The program is estimated to provide a 2012 load reduction amount of 117.6 2 MW from the Series 1 and 2 rates and 0.57 MW from the super peak rate. The 118.2 MW total load reduction will provide 517,585 MWh of annual savings from January through December 2012. Load reduction and savings targets are summarized in Table 8 – DR Program/Initiatives: 2012 Load Reduction and Energy Savings: January – December 2012.
