The Arizona Corporation Commission has directed its staff to develop a set of rules to achieve 100% clean energy by 2050, said Commission Chair Robert Burns in a\u00a0letter\u00a0on Wednesday.<\/p>\n\n\n\n

Commissioner Sandra Kennedy\u00a0wrote\u00a0the same day that while she preferred a standard of 100% clean energy by 2040, because \u201cthe science is clear regarding the need for aggressive decarbonization,\u201d she would support a 2050 deadline to achieve majority agreement.<\/p>\n\n\n\n

Commissioner Lea Marquez Peterson voiced her support for 100% clean energy by 2050 in a\u00a0letter\u00a0last week. The three commissioners constitute a majority of the five-member commission, and a fourth commissioner, Boyd Dunn, voiced his support for the standard in an informal \u201cvote\u201d called by Chairman Burns at a recent meeting, said a press release from conservation group Western Resource Advocates.<\/p>\n\n\n\n

Burns said in his letter that \u201cwhen it comes to renewable energy resources, I believe everyone agrees that these costs are dropping.\u201d As evidence, he provided a link<\/a> to recent renewable energy prices in Arizona and the West, published by WesternGrid.net.<\/p>\n\n\n\n

Burns also noted recently established Commission requirements for utilities to develop an integrated resource plan (IRP), a process in which the Commission will oversee both the utility\u2019s load forecast and its all-source request for proposals, and consider stakeholder input. The utility must then choose its future resources from the results of the RFP. \u201cThe IRP process is the most important\/crucial part of the rules we will be adopting,\u201d Burns wrote.<\/p>\n\n\n\n

Kennedy in her letter added that \u201cenergy efficiency is the least cost resource, while renewable energy and battery storage technologies are consistently beating out natural gas and other resources on price. This is the case even when social costs of carbon, water use, coal ash, and other externalities are not included in the pricing.\u201d<\/p>\n\n\n\n

Western Resource Advocates is one of 32 groups, shown below,\u00a0calling for\u00a0Arizona to reach 50% renewables by 2030, up from about 7% now, which is mostly\u00a0solar. The groups also call for 100% clean energy by 2045, and define \u201cclean\u201d as emitting no carbon dioxide\u2014a technology-neutral standard that would permit solar, wind, nuclear, and gas with carbon capture and storage, said Adam Stafford, Western Resource Advocates\u2019 staff attorney in Phoenix.<\/p>\n\n\n\n

Fourteen other states have mandates or goals for 100% clean or renewable electricity by 2050 or earlier, as do Washington, DC and Puerto Rico, as shown in the map above from Advanced Energy Economy.<\/p>\n\n\n\n

The Arizona Corporation Commission is the state\u2019s \u201cco-equal, fourth branch of government,\u201d says a commission press release. It was established by the state constitution to regulate public utilities, and its members are elected by the voters of Arizona.<\/p>\n\n\n\n

Arizona could join 16 other states and territories that have targets of 100% clean or renewable electricity by 2050 or sooner. Thirty-two groups in Arizona have called for 50% renewables by 2030. The Arizona Corporation Commission has directed its staff to develop a set of rules to achieve 100% clean energy by 2050, said Commission…
