WIEB Inventory of Clean Energy Policies
as of October 3, 2022
The WIEB Inventory of energy policies seeks to identify and summarize the major clean energy policies of the states and provinces of the Western Interconnection. The Inventory is based upon multiple sources of public information and will be reviewed and updated by the states and provinces on a biennial basis.
RPS targets:
Applies to IOUs and Coops w/ 50% load in AZ:
- 10% in 2020
- 11% in 2021
- 12% in 2022
- 13% by 2023
- 14% by 2024
- 15% by 2025+
DG minimum
30% of RPS energy from DG
Clean Energy Targets:
Utilities required to attain CO2 reductions in 5 steps:
- 50% by 2032;
- 65% by 2040;
- 80% by 2050;
- 90% by 2060;
- 100% by 2070
GHG Reduction Targets:
-none-
Net Metering:
New customer-generators receive a credit for exported energy based on the ACC’s avoided cost methodology. The ACC would apply and review avoided cost rates to individual utilities through the utility rate cases. (ACC Decision No. 75859, 2016)
Energy Efficiency Resource Standard:
ACC adopted energy efficiency standard in 2010 requiring IOUs and Coops to attain cumulative annual saving targets from 2011 to 2020. IOUs cumulative EE target was 22% by 2020. Coops cumulative EE target was 16.5% by 2020. Salt River Project adopted its own target. Utilities can meet their targets through DSM, peak reductions, building codes, combined heat & power, and their own initiative.
Building Codes:
Since AZ is a home rule state, building codes are enforced on the local rather than state level. Majority of construction occurs in jurisdictions that have adopted 2012, 2015 or 2018 International Energy Conservation C+E34+E36
Appliance Standards:
AZ enacted energy efficiency appliance standards covering 12 categories in 2008-10. All were preempted by federal standards. Three new appliance standards were enacted in 2012 covering pool pumps, pool pump motors, and+E34+E36

EV Policies:
ACC adopted EV policies in 2018 and 2019 that encourages utilities to develop rates and pilot programs to promote EV development. IOUs allowed to recover prudent costs for charging infrastructure. Encouraged rate designed that encouraged charging during off-peak hours. HOV lane exemptions for EVs and other alternative fuel vehicles. Reduced license fees for EVs and other alternative fuel vehicles
Energy Storage:
In 2016, the ACC directed APS to develop a $4 million plan to use residential-sited storage for demand response and load management programs. In 2017 rate case, the ACC approved a request of APS to include $2 million annual incentive program to encourage larger commercial customers to deploy energy storage to reduce peak loads.

RPS targets:
Applies to all electric utilities:
- 33% in 2020
- 44% in 2024
- 52% in 2027
- 60% in 2030
- 100% renewable and zero carbon resources in 2045 (SB 100, 2018)
Clean Energy Targets:
Utilities must have 100% retail electricity produced from renewable and zero carbon resources by 2045 (SB 100 in 2018)
GHG Reduction Targets:
GHG reductions from 1990 baseline:
- return to 1990 level by 2020;
- 40% by 2030;
- 80% by 2050
(AB 32 in 2006; SB32 in 2016)
Net Metering:
Net metering available to customer-generators with PV and other energy systems up to 1 MW can export power to grid and receive credit at retail rate. Customers pay an interconnection fee, non-bypass charges on the grid and participate in time-of-use rates. Prohibits fixed charges such as demand charges, grid access charges, installed capacity fees, and standby fees. (First enacted in 1996 with multiple revisions to “Net Metering 2.0”)
Energy Efficiency Goal:
In 2006, AB2021 called for a 10% reduction of energy consumption in 10 years. In 2015, SB 350 raised the goal for a doubling energy efficiency savings in electricity and natural gas end uses by 2030 relative to 2015 level. CEC issues EE Action Plan with steps to attain the EE goal every 3 years
Building Codes:
In 1976, adopted building codes to improve energy efficiency. The current Building Energy Efficiency Standards are updated every 3 years by the CEC (Title 24, Parts 6 and 11). The 2019 code update for residential buildings requires solar PV system for all new homes starting in 2020. The 2019 update for non-residential buildings requires alignment with the ASHRAE 90.1 2017 national standards.
Appliance Standards:
In 1974, CA was the first state to adopt energy efficiency standards for appliances. Federal appliance standards have since pre-empted certain categories of appliances. CA maintains appliance regulations in many areas that cover 15 categories of energy and water appliances. (Title 20)

EV Policies:
In 1990, CARB adopted a zero emission vehicle (ZEV) standard as part of its low emission vehicle (LEV) requirements. ZEV standards require auto manufacturers to produce a specified number of ZEVs each year based on a credit system. Combined ZEV and LEV sales in 2025 are estimated to 8% of CA’s annual car sales. To date, 13 other states have adopted CA’s ZEV and LEV standards including: CO, NV, OR and WA. CARB’s EV Rebate Program provides up to $750 for purchase or lease of new EV or Plug-in hybrid. CPUC advances ZEV deployment through electric rate design, electric infrastructure deployment, and grid management. CEC has funded more than 8,800 EV charging stations across the state.
Energy Storage:
CA PUC established electric storage procurement levels for IOUs: 1325 MW by 2020 among 3 IOUs: SCE: 580 MW; PG&E: 580 MW; SDG&E: 165 MW (AB 2514, 2013 and CPUC Decision No. 13-10-040); Distributed storage 500 MW by 2020 (AB 2868, 2016). Self-Generation Incentive Program set aside $378 million for customer sited energy storage projects from 2017 to 2021. CPUC decision to allow net metering with storage provided power controls prevent the storage device from charging from the grid or exporting to the grid (CAPUC Decision 19-01-030, 2019)
