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:

Call to Action- Arizona Legislature at it again!

URGENT ACTION NEEDED!
 
Call to Action!
The legislature introduced two bills (HB2248/SB1175) that would strip the Arizona Corporation Commission of its authority to proceed with the final adoption of the Clean Energy Rules package passed last year and its ability to require the procurement of any specific type of generation.
 
Stakeholders have been working with the ACC and each other for nearly four years on the adoption of these Energy Rules. This legislation seeks to undo these years of work and would deprive businesses of the certainty they have been working so hard to achieve through the rule process.
 
The passage of HB 2248 and SB 1175 creates massive regulatory uncertainty for businesses who wish to conduct business in Arizona or expand or relocate here.
Nearly all the largest businesses in the Country are demanding options for 100% clean energy and cannot be expected to look to locate in states that are making it harder, instead of easier, to acquire clean energy. These bills are sending a message that Arizona is not looking to the future, is not keeping up with technology, and is not interested in reaching out to key job creators.
 
Is this really the time to say “Arizona is closed for business?”
Act now and tell the members of the House and Senate Natural Resource, Energy and Water Committee to VOTE NO on HB 2248 and SB 1175.
 
THINGS YOU CAN DO:
1.    Sign into “Request To Speak,” and state you are in opposition to this bill. Create an account here. (Note you will have to activate or have someone activate your account at the Capitol. If you have an account from previously, it will still be active.)
 
2.    Speak virtually against HB2248 in the House Natural Resources, Energy, and Water Committee meeting, happening this Tuesday, January 19th @ 2:00pm.
Email [This email address is being protected from spambots. You need JavaScript enabled to view it.] by 2:00 pm TODAY (1/15) to reserve your spot. Note that you should also sign in on Request to Speak. You will be provided with a Zoom link so that you can testify remotely. 
 
3.    Speak virtually against SB1175 during the Senate Natural Resources, Energy, and Water Committee meeting, happening this Wednesday, January 20th @ 2:00pm. Email [This email address is being protected from spambots. You need JavaScript enabled to view it.] 24 hours beforehand. Note that you also need to sign in on Request to Speak.
 
4.    Email the committee members, ask them to vote no stating the impact that the passage of these two bills will have on Arizona businesses, the economy and jobs. Include your own personal touch and how this will impact YOU!
 
House Committee Emails NO on HB 2248
 
Senate Committee Emails NO on SB 1175
 
Thank you for your urgent actions on this!

Trump Proclamation increases tariff on imported solar panels and revokes bifacial’s exemption

The President Trump released a Proclamation  on October 10, 2020 that will increase the tariff on imported solar cells and panels next year.  Bifacial solar panels will officially lose their exemption status.

The solar industry was the first market to feel the hit of tariffs brought on by Trump in 2018. Beginning in February 2018, imported crystalline silicon cells, modules and AC/integrated modules were tariffed 30% as part of a four-year outline. Imports received a 25% tariff in 2019, a 20% tariff in 2020 and were scheduled for a 15% tariff in 2021.

Update (10/15/20):  A U.S. trade court again denied a request by the Trump administration to end a tariff exemption for imported two-sided solar panels. (caution: paywall)

U.S. Court of International Trade Judge Gary Katzmann refused to lift an order preventing the administration from withdrawing an exemption for two-sided, or bifacial, panels The government didn’t follow the law the first time it moved to withdraw the loophole, and it didn’t fix the procedural errors the second time it tried, Katzmann said. Katzmann said he was taking no position on whether the duties would protect the domestic solar industry “Once again, the court merely continues to...

APS sets course for 100 percent clean energy future

Arizona Public Service Co. has announced that it plans to produce all of its electricity from carbon-free sources by 2050 and will get 45% of its power from renewable sources like solar and wind by the end of this decade.

This is a good improvement from the point of view of sustainable energy.  There are still a lot of details to be worked out such as the role that distributed energy will take.  Will APS APS improve its policies in regard to residential and small commercial systems.

There are several good news articles and the APS press releases on this announcement:

APS:APS sets course for 100 percent clean energy future

Arizona Republic: APS will eliminate carbon emissions by 2050 and close coal plant ahead of schedule, CEO says

The Washington Post: Arizona’s biggest utility says it will get all of its electricity from carbon-free sources by 2050

SRP approves rate decrease as directors argue about solar power and batteries

During March 2019, SRP wrapped up their public pricing process at a final rate setting board hearing.

The board approved new rates for SRP customers, which will translate to a $1 to $4 decrease in monthly bills.
The board also voted to lower rates for solar customers, approve three new options for solar customers, and adopt a new battery/storage incentive.
