CHP Summary List All

Arizona includes CHP as an eligible resource in its EERS and has adopted policies to support renewable-fueled CHP systems. No new CHP systems were installed in 2018.

Interconnection StandardsList All

In June 2007, the Arizona Corporation Commission (ACC) initiated a rulemaking process to establish statewide interconnection standards for distributed generation. This proceeding is still in progress. Draft rules released June 26, 2015 are available here and a ruling is still pending, but the commission has recommended utilities use the draft regulation until regulations are finalized.

The state's utilities independently developed interconnection agreements for distributed generation (DG) prior to the ACC's ongoing proceeding to establish statewide standards. The Salt River Project, Tucson Electric Power, and Arizona Public Service—the state’s major utilities—have all established their own interconnection procedures. It is likely that the state’s regulated utilities will adopt the ACC’s interconnection standards when final rules are adopted.

Encouraging CHP as a ResourceList All

CHP in energy efficiency standards: On December 18, 2009 the Arizona Corporation Commission (ACC) ordered that all investor-owned utilities and rural electric cooperatives achieve 1.25% annual savings as a percent of the retail energy sales in the prior calendar year, ramping up to 2% beginning in 2014. By 2020, the state should reach 20% cumulative savings, plus up to a 2% credit for peak demand reductions from demand response programs, for a total standard of 22%. CHP is an eligible efficiency measure and utilities can choose to use CHP to meet their goals, although there is no separate CHP target within the EERS.

Additional Supportive PoliciesList All

Arizona has policies to encourage the use of renewable-fueled CHP systems, waste heat to power (WHP) and biomass or biogas systems. These systems qualify for Arizona’s Renewable Energy Standard (RES) adopted by the Arizona Corporation Commission (ACC) in November 2006. The final rule expands the RES to 15% by 2025, with 30% of the renewable energy to be derived from distributed energy technologies. The standard allows for "Renewable Combined Heat and Power Systems," distributed generation systems, fueled by an eligible renewable energy resource, and produce both electricity and useful renewable process heat. Both the electricity and renewable process heat may be used to meet the standard’s Distributed Renewable Energy Requirement.

Renewable-fueled CHP systems may also be eligible for Renewable Energy Business Tax Incentives. Signed in July of 2009, SB 1403 created tax incentives intended to draw renewable energy product manufacturers to Arizona. To be eligible, businesses must meet certain minimum requirements for the quantity and quality of new jobs created. If approved, businesses may be eligible for income tax credits or property tax incentives. These incentives will be expire on December 31, 2019.

Utilities Summary List All

Arizona historically has been a leader in utility-sector energy efficiency. In 2010, the Arizona Corporation Commission (ACC) ordered that all investor-owned utilities must achieve  22% cumulative savings by 2020 (including a 2% credit for peak reductions from demand response). Regulated rural electric cooperatives were required to meet 75% of this standard. Energy savings targets were extended in a 2022 ACC Order that acknowledged and modified integrated resource plans (IRPs) of  Arizona Public Service Company (APS), Tucson Electric Power (TEP), and UNS Electric (UNSE). These requirements call for APS and TEP to achieve at least 1.3% annual energy efficiency savings over the next three-year planning period and to report these savings in their 2023 Integrated Resource Plan.

Arizona’s two largest investor-owned electric utilities, APS and TEP, operate a variety of demand-side management (DSM) programs applicable to a range of customers. Programs are administered by each utility and funding varies by utility. Utilities submit program plans to the ACC and commission approval is required before implementation. Arizona’s second largest electric utility, the Salt River Project (SRP), is a public utility and also offers a comprehensive range of efficiency programs. The utility’s board approves SRP’s funding for demand-side management.

The most recent budgets for energy efficiency programs and electricity and natural gas savings can be found in the State Spending and Savings Tables.

Customer Energy Efficiency Programs List All

Under the Arizona Administrative Code, electric and gas utilities must administer efficiency programs to meet targets set by the state’s energy efficiency resource standard (EERS). The Arizona Corporation Commission (ACC) approves program funding and spending for regulated utilities. Energy efficiency programs in Arizona are funded through an adjustor mechanism or collected through a non-bypassable surcharge on electricity bills, depending on the utility.

Arizona Public Service Company (APS), a major investor-owned utility and Arizona’s largest electric utility, operates a variety of residential and non-residential programs, including several successful DSM programs for residential and non-residential customers. Tucson Electric Power Company (TEP) recently received approval for updates to its DSM Program Portfolio, which includes programs for both residential and non-residential customers.

UniSource Gas and Southwest Gas also operate some energy efficiency programs.

Salt River Project, a public utility, has recently ramped up its energy efficiency programs. It seeks to achieve 20% of its expected retail sales through the implementation of energy efficiency and renewable resources by FY 2020. The utility has also set energy efficiency targets of 1.5% annual savings between FY 2012-2014, 1.75% between FY 2015-2017, and 2% between FY 2018-2020.

Energy Efficiency as a Resource List All

Arizona utilities have developed diverse resource portfolios that include energy efficiency as a resource. To address anticipated demand increases, Arizona Public Service and Tucson Electric Power plan to continue to expand already successful energy efficiency programs. In April 2015, the ACC required that regulated electric utilities specifically include, or explain why they exclude, energy storage and expanded energy efficiency and demand response in their integrated resource plans. (See Docket No. E-00000V-13-0070 and Decision No. 75068.)

Salt River Project's investment in energy efficiency is guided by its Sustainable Portfolio Principles, which direct the utility's current and future use of energy efficiency and renewable energy resources.

Energy Efficiency Resource Standards List All

Summary: In February 2022, the Arizona Corporation Commission issued a Decision modifying Integrated Resource Plans (IRPs) for APS, TEP, and UNS Electric. As part of the approval both APS and TEP are required to achieve at least 1.3% annual energy efficiency savings over the next three-year planning period and to report these savings in their 2023 Integrated Resource Plan.  Both utilities are also required to include a demand-side resource capacity equal to at least 35% of  2020 peak demand. 

An earlier EERS adopted in 2010 by the Arizona Corporation Commission ordered that, by 2020, each investor-owned utility must achieve cumulative annual electricity savings of at least 22% of its retail electric sales in calendar year 2019 through cost-effective energy efficiency programs (see Docket No. RE-00000C-09-0427Decision No. 71436, and Decision No. 71819). Cumulative annual targets for electricity savings were specified for each year, beginning at 1.25% in 2011, and based on retail electricity sales in the previous calendar year. Electric distribution cooperatives were required to propose an annual energy savings goal that is at least 75% of the standard in a given year.

A natural gas energy efficiency standard required 6% cumulative savings by 2020 (see Docket No. RG-00000B-09-0428 and Decision No. 71855). As in the case of electric cooperatives, gas cooperatives must propose annual savings goals that achieve 75% of the standard; propane companies must meet 50% of the standard. Energy savings from renewable energy projects sponsored by an affected utility may count towards meeting up to 25% of the standard in any given year.

Salt River Project has also set long-term energy savings goals through its Sustainable Portfolio Principles. These principles establish targets for the utility through its 2020 fiscal year and ramp up to 2% beginning in FY 2018.

On December 13, 2011, the ACC approved a full revenue decoupling mechanism for Southwest Gas as part of the utility's rate case (Docket No. G-01551A-10-0458). 

On May 24, 2012, the ACC approved a lost revenue adjustment mechanism (LRAM) for the Arizona Public Service Company as part of the utility’s rate case (Docket No. E-01345A-11-0224). In June 2013, an LRAM was also approved for Tucson Electric Power Company (Docket No. E-01933A-12-0291). UniSource Energy Services also operates under an LRAM.

Arizona Public Service (APS) has a tiered shareholder performance incentive that is based on a percentage of the net benefits from energy savings and capped as a tiered percentage of program costs. The incentive is capped at $0.0125 per kWh saved (See ACC Decision 74406).

Tucson Electric Power (TEP) also has a performance incentive in place. The most recent incentive became effective July 2013 (See ACC Decision 73912). TEP receives a share (8%) of net benefits. The incentive is capped at $0.0125 per kWh saved.

Evaluation, Measurement, & Verification List All
  • Primary cost-effectiveness test(s) used: societal cost test
  • Secondary cost-effectiveness test(s) used: none

The evaluation of ratepayer-funded energy efficiency programs for Arizona’s regulated utilities relies on regulatory orders (A.A.C. R14-2-2409 and R14-2-2415). Third parties conduct evaluations for each regulated utility. Arizona has established formal rules and procedures for evaluation, documenting them in A.A.C. R14-2-2409 and R14-2-2415. Arizona uses the Societal Cost Test (SCT) and considers it the primary cost-effectiveness test; SCT rules are in A.A.C. R14-2-2401(36) and R14-2-2412(B).

According to the Database of State Efficiency Screening Practices (DSESP), Arizona applies the Societal Cost Test (SCT) primarily at the portfolio level and secondarily at the program and measure level. Arizona’s SCT accounts for non-energy costs and benefits associated with productivity (improved systems operations), health and safety, participant satisfaction (customer service), water savings, environmental impacts, and public health (health effects from burning fossil fuels).

Further information on cost-effectiveness screening practices for Arizona is available in the Database of State Efficiency Screening Practices (DSESP), a resource of the National Efficiency Screening Project (NESP).

Guidelines for Low-Income Energy Efficiency Programs List All

Requirements for State and Utility Support of Low-Income Energy Efficiency Programs

No specific required spending or savings requirements were identified. In 2010, the Arizona Corporation Commission (ACC) ordered in Decision 71819 that each investor-owned utility must achieve cumulative annual electricity savings of at least 22% of its retail electric sales in calendar year 2019 through cost-effective energy efficiency programs. The decision ordered that utilities “…allocate a portion of DSM resources specifically to low-income customers,” but does not identify a minimum spending level.

Utility funds dedicated to weatherization, in addition to DOE funds for weatherization, are managed by the Arizona Department of Housing (ADOH).

Cost-Effectiveness Rules for Low-Income Energy Efficiency Programs

Since 2011, Arizona Administrative Code Title 14, Chapter 2, Article 24 (R14-2-2412) has directed that “…an affected utility’s low-income customer program portfolio shall be cost-effective, but costs attributable to necessary health and safety measures shall not be used in the calculation.”

Self Direct and Opt-Out Programs List All

All the major electric utilities offer a self-direct option for large customers. Arizona Public Service (APS) states that large customers using at least 40 million kWh per calendar year can elect to self-direct energy efficiency funds. Customers must notify APS each year if they wish to participate, after which 85% of the customer's demand-side management contribution will be reserved for future energy efficiency projects. Projects must be completed within two years. Self-direction funds are paid once per year once the project is completed and verified by APS. To be eligible for self-direction under Tucson Electric Power, a customer must use a minimum of 35 million kWh per calendar year. The Salt River Project makes self-direction available only to very large customers using more than 240 million kWh per year. For all utilities, a portion of the funds they would have otherwise contributed to energy efficiency is retained to cover the self-direction program administration, management, and evaluation costs.
