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:

Arizona HOA demands extra cash for solar-panel review

In Arizona it is common for homeowners associations (HOA) to require homeowners or their contractors to obtain the HOA's permission to install a solar system.  There is usually a minor fee.  At least one HOA has taken this to an extreem, charging for an architect to review the plans and installation for $1500 ($500, to have an architect review plans, plus a $1,000 refundable deposit to ensure the installation happens as submitted.).

Tim Steller of the Arizona Daily Star has a good article on this situation:Steller column: HOA demands extra cash for solar-panel review

Seeking Arizona agriculture producers who are using small solar systems in their operations in Arizona

Dr. Bonnie Eberhardt Bobb, Executive Director of the Western Sustainable Agriculture Working Group, is looking for agriculture producers who are using small solar systems in their operations in Arizona who might be willing to help her with preparing ACC testimony, discussion with representatives, writing letters of support, signing petitions, etc. to further their goal of increased renewables in agriculture. She would love to hear from ag producers and listen to their stories of how solar has benefited their operations. Thank you so much.

SRP Solar Information

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.

The Challenge of Closing the Navajo Generating Station coal-fired power plant near Page

The Navajo Generating Station in Page, Arizona will soon be closed. This is one of the largest coal fired power plants in the U.S and is supplied by a dedicated mine (Kayenta Peabody Mine) about 80 miles east of Page. The plant and mine have provided the Navajo Nation with employment and income, but at high enviromental cost (one of the biggest polluters in the nation). The decision by the plant owners (Salt River Project owns 42.9% of the plant and runs it for the owners, which include the U.S. Bureau of Reclamation (24.3%), Arizona Public Service Co. (14%), Tucson Electric Power Co. (11.3%) and NV Energy (7.5%)) was based on the economics of operating the plant. The economics of electrical power generation are changing and coal fired plants are now the most expensive to operate. Renewable sources such as solar and wind, and the low cost of natural gas are causing the early retirement of many coal fired power plants.

The plant was completed in 1975 for a total cost of about $650 million. Since then far more has been spent on polution controls and more would have been needed to continue operations. In addition, the plant and its supply of coal have a major user of water in an arid area.

The main decision to close the plant was made in 2017. A Replacement Lease was negotiated by the Navajo Nation to extend operation to 2019 in the hopes of finding a new owner to continue the operations. On March 21, 2019 Navajo lawmakers voted to end their efforts to acquire the plant and keep it running.

A Navajo Nation brochure in 2017 has a good summary of the situation then. The Replacement Lease was approved and one of the plant assets transferred to the Navajo Nation are the transmission rights. The Navajo Nation or its assignee can use the transmission rights to have electric energy from new solar or other generation sources delivered to markets such as California, Phoenix and Las Vegas. These transmission rights are a valuable new tool that will position the Nation’s movement toward a cleaner energy economy.

There is also a good 2017 summary on High Country News: https://www.hcn.org/articles/the-wests-coal-giant-is-going-down

There is also a good article, funded by NREL, on the potential for solar on the Navajo Nation that pre-dates the decision to close the Navajo Generating Station: Growing Interest in Developing Navajo Utility-Scale Solar Industry.

UPDATE 3-3-19

Utility Drive reported that On Sunday 3-31-19, an Arizona federal judge granted a motion to dismiss a lawsuit that sought to force a state water agency (the Central Arizona Project) to buy coal-fired electricity from this facility.
