Update April 27, 2022-- Today Electric companies in Arizona won't have to worry about competing for customers after Gov. Doug Ducey signed the bill described below that repeals laws allowing for Competition.  See the AZ Central article.


The current 2022 session of the Arizona Legislature has passed House Bill 2101 which would repeal most of the state’s electricity retail competition rules.  No surprise that this bill and Senate Bill 1631 are being supported by all the major Arizona electric utilities (APS, SRP, and TEP). 

In 1998 Arizona enacted a law that allowed for a phasing in of a competitive electric energy market. For various reasons this competitive market did not develop. Recently, in reaction to Texas-based Green Mountain Energy's August 2021 application to the Arizona Corporation Commission (ACC) to begin selling what they claim are 100% renewable energy plans to customers in Arizona Public Service (APS) and Tucson Electric Power's (TEP) service areas, the utilities seek to prevent that from being able to go forward. The result is HB2101/SB1631.

Specifically removed from Arizona law is the concept "It is the public policy of this state that a competitive market shall exist in the sale of electric generation service. ".

The Arizona Republic had a good opinion article on this.

The Arizona Solar Energy Industries Association (AriSEIA), a nonprofit trade association representing the solar and storage industry in Arizona, opposes HB2101.

The 9th Circuit Court of Appeals recently issued a landmark decision regarding rooftop solar. Ellis v. Salt River Project (SRP) was decided on Monday, January 31, 2022. The case is a class action lawsuit against SRP for its treatment of rooftop solar customers. In 2014, SRP announced its E-27 rate plan, which increased costs for rooftop solar customers by 65% and resulted in a decrease of rooftop solar applications by 50-96%.

Should HB 2101 become law, the statutes that the 9th Circuit relied on to rule in favor of rooftop solar customers would be eradicated and the outcome of the case would very likely be different.

The Rose Law Group, active in renewable energy, has an interesting article on how the utilities circulated a misleading “fact sheet” to legislators:

Biden releases ambitious plan for solar energy

By Ivan Penn | New York Times

The Biden administration on Wednesday released a plan to produce almost half of the nation’s electricity from the sun by 2050 as part of its effort to combat climate change.

Solar energy provided less than 4 percent of the country’s electricity last year, and the administration’s target of 45 percent would represent a huge leap and will most likely take a fundamental reshaping of the energy industry. In a new report, the Energy Department said the country needed to double the amount of solar energy installed every year over the next four years compared with last year. And then it will need to double annual installations again by 2030.

Here is What it Will Cost You to Achieve 100% Clean Energy -Intro

On August 12, 2021 the Office of Arizona Corporation Commission Chairwoman Lea Márquez Peterson released an interesting summary of the average future bill impact to residential customers  up to 2050, depending on the utility and the amount of emission reductions that each utility achieves within that time.  Worth a read.

PHOENIX - Several clean energy proposals are currently pending before the Arizona Corporation Commission. After several months, the Commission has received an independent analysis of at least two of these proposals: 100 percent zero-emission energy by 2050 and 80 percent clean energy by 2050.

Energy_Bills_2021

The Arizona Legislature's session had many energy bills to oppose (HB2248, SB1175, HB2737 in particular).  These died at the end of the session, but the concepts could be presented in the future.

Status of 2021 Session Bills:
DEAD-HB 2248: Corporation Commission; Electric Generation Resources
Alarm bells are ringing by environmentalists over HB2248 (and Senate bill 1175). These would prohibit “Arizona Corporation Commission from adopting or enforcing any policy, decision or rule that directly or indirectly regulates critical electric generation resources used or acquired by public service corporations within Arizona’s energy grid without express legislative authorization. (Sec. 1) 2.” The bill cripples the ACC from doing its job. (Kerr, Gowan, Gray and others). The House passed a Senate committee 6-4 but was caught up in committee when the Legislature adjourned.

DEAD-SB 1175: Corporation Commission; Electric Generation Resources
See above.

DEAD-HB 2737: Corporation Commission Actions; Investigation
Dead. Environment – HB2737, would allow any lawmaker to order Arizona’s Attorney General to investigate the Arizona Corporation Commission and to require 10% of the commission’s operating budget to be withheld if the AZ Supreme Court determines this agency has exceeded its statutory authority or is not executing or enforcing statute. Sponsored by Jacqueline Parker (R-16). Probably aimed at curbing the ACC environmental regulations. Passed Committee of the Whole but not voted on in time.

Thanks to all who voiced their opposition to the above bills. It is imperative that we convey the negative impact passing bills such as these will have on the regulatory certainty that companies rely on to locate, relocate and grow. We need to protect our state’s economy, our health and our future. Email your representatives.
