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 administration announces goal of 5 million homes

The Department of Energy on November 5, 2021 announced a target of the equivalent of five million homes powered by community solar energy by 2025.

The target would save $1 billion and contribute to administration goals of fully renewable electricity by 2035, according to the department.

“Community solar is one of the most powerful tools we have to provide affordable solar energy to all American households, regardless of whether they own a home or have a roof suitable for solar panels,” Energy Secretary Jennifer M. Granholm said in a statement. “Achieving these ambitious targets will lead to meaningful energy cost savings, create jobs in these communities, and make our clean energy transition more equitable.”

The Build Back Better plan for renewables-2021

On OCTOBER 28, 2021 President Biden Announced the Build Back Better Framework. This will have a major impact on Renewable Energy and sustainability. Some of the major components are:

  • The largest effort to combat climate change in American history. The framework will cut greenhouse gas pollution by well over one gigaton in 2030, reduce consumer energy costs, give our kids cleaner air and water, create hundreds of thousands of high-quality jobs, and advance environmental justice by investing in a 21st century clean energy economy – from buildings, transportation, industry, electricity, and agriculture to climate smart practices across our lands and waters.

 

  • Ensure clean energy technology – from wind turbine blades to solar panels to electric cars – will be built in the United States with American made steel and other materials, creating hundreds of thousands of good jobs here at home. The Build Back Better legislation will target incentives to grow domestic supply chains in solar, wind, and other critical industries in communities on the frontlines of the energy transition. In addition, the framework will boost the competitiveness of existing industries, like steel, cement, and aluminum, through grants, loans, tax credits, and procurement to drive capital investment in the decarbonization and revitalization of American manufacturing.

 

  • Advance environmental justice through a new Clean Energy and Sustainability Accelerator that will invest in projects around the country, while delivering 40% of the benefits of investment to disadvantaged communities, as part of the President’s Justice40 initiative. The framework will also fund port electrification; facilitate the deployment of cleaner transit, buses, and trucks; and support critical community capacity building, including grants to environmental justice communities. In addition, the framework will create a new Civilian Climate Corps – with over 300,000 members that look like America. This diverse new workforce will conserve our public lands, bolster community resilience, and address the changing climate, all while putting good-paying union jobs within reach for more Americans.

Scottsdale Proposes Adoption of new Energy and Green Construction Code

In alignment with Scottsdale’s overall building code updates, the city is preparing to adopt the 2021 edition of the International Green Construction Code (IECC) and the International Green Construction Code (IgCC). These updated codes will replace the currently adopted 2015 editions.

The IECC addresses residential and commercial energy efficiency on several fronts including cost savings, reduced energy usage, conservation of natural resources and the impact of energy usage on the environment. Key changes to the 2021 IECC improve efficiency by 11.1 percent and reduce greenhouse gases by 10.7 percent over the 2015 IECC. These changes include new provisions that increase efficiency and encourage greater flexibility in design and construction. Amendments include electric vehicle charging infrastructure for new homes, apartments and hotels to support future EV charging demand. The IgCC is applicable to new commercial buildings and contains measures to help mitigate heat island effect, reduce water waste, mitigate greenhouse gas emissions, support renewables, improve indoor environmental health and lower the impact on natural resources.

The updated codes are planned to be presented to City Council for adoption in the first quarter of next year. The IECC and IgCC have already received support from the Scottsdale Environmental Advisory Council and is currently being reviewed by the Building Advisory Board.
