• New Discovery Could Improve Organic Solar Cell Performance

    While there is a growing market for organic solar cells ­­– they contain materials that are cheaper, more abundant, and more environmentally friendly than those used in typical solar panels – they also tend to be less efficient in converting sunlight to electricity than conventional solar cells. Now, scientists who are members of the Center for Computational Study of Excited-State Phenomena in Energy Materials (C2SEPEM) a new Read More
  • Know Your Rights

    Arizona law protects individual homeowners’ private property rights to solar access by dissolving any local covenant, restriction or condition attached to a property deed that restricts the use of solar energy. This law sustained a legal challenge in 2000. A Maricopa County Superior Court judge ruled in favor of homeowners in a lawsuit filed by their homeowners association seeking to force the homeowners to remove Read More
  • Home Battery Systems

    Rooftop solar panels are common in Arizona thanks to abundant sunshine, but to get even more use from the technology, homeowners are beginning to pair them with large home batteries. Batteries allow homeowners to store their surplus electricity, rather than send it to the grid in exchange for credit from their electric company. Read More
  • Solar Hot Water

    There are two types of solar water heating systems: active, which have circulating pumps and controls, and passive, which don't. The typical solar water heater is comprised of solar collectors and a well-insulated storage tank. The solar collector is a network of pipes that gathers the sun's energy, transforms its radiation into heat, and then transfers that heat to either water or a heat-transfer fluid. Read More

What’s Really Green and What’s Really New

Ask Americans what the Green New Deal is all about, and you’ll get two basic answers. Most often you’ll hear, “It’s about moving to renewable energy in order to fight climate change.” You’ll also hear, from a camp further right, “It’s all about socialism!”

Some things to pay attention to in Arizona


Arizona Legislature 

Call to Action - HB 2248 and SB 1175 would create massive regulatory uncertainty for businesses who wish to conduct business in Arizona. Call your representatives now. Click on 'Call to Action' for details.

 

The Arizona Legislature is in session and there are some energy bills to oppose (HB2248, SB1175, HB2737)

Status of Bills:
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. Last action early April.

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

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.

Please continue to tell your state legislator to vote no on HB 2248, SB 1175 and HB 2737. It is imperative that we convey the negative impact passing these bills 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.

Arizona Corporation Commission 

On May 26th 2021, the Arizona Corporation Commission reconsidered and passed a Clean Energy Rules package. The energy rules package includes 100% carbon-free energy in Arizona by 2070. And the carbon reductions are requirements and not goals.

Revised carbon emissions reductions levels by the following:
• 50% by December 31, 2032
• 65% by December 31, 2040
• 80% by December 31, 2050
• 95% by December 31, 2060
• 100% by December 31, 2070

Most importantly, the passed rules retained all the beneficial policies and requirements around storage and distributed storage. Specifically, the rules include a 35% energy efficiency requirement, which is the nation’s first distributed storage/solar requirement, preferential treatment for energy procurement from coal-impacted communities and tribes, as well as a complete rewrite of the IRP rules that will require the Commission to approve, rather than acknowledge a preferred portfolio of resources.

This is not yet final, as a result of substantive changes made to the original Recommended Opinion and Order, the amended energy rules package will be sent back through the formal rulemaking process. An updated schedule will be implemented that will allow for written comments and public comment on the record. Interested parties can submit formal written comments to the docket beginning July 9, 2021 through August 20, 2021. Public comment sessions will be held on August 16 and 19, 2021, at 10am.

The passage of the Energy Rules as they presently stand reflects a significant win for ratepayers, for the people of Arizona and for the Solar Energy Industry.

The Nature Conservancy has submitted their report "Arizona Thrives - A Path to a Healthy and Prosperous Future" to the ACC. Interesting.

APS has submitted their report,  The Solar Center has slightly reformatted this report by rotating the pages for easier viewing.  APS has provided two presentations to address the ACC questions. Worth a read.

Update July 30, 2020: 

When the Arizona utility regulators met to decide these issues they deadlocked over whether they should increase the state's requirements for renewable energy. It proved not possible to obtain the agreement of at least three commissioners, the meeting was adjourned.

See the Arizona Republic article on this:  Arizona utility regulators hit roadblock on clean-energy rules, abruptly end meeting.

The Arizona Corporation Commission (ACC) has released the Notice of Final Rulemaking Interconnection of Distributed Generation FacilitiesInterconnection of Distributed Generation Facilities document.

With this rulemaking, the Commission adds a new Article 26, entitled " Interconnection. of Distributed Generation Facilities" to 14 A.A.C. 2, the Chapter containing the Commission's rules for fixed utilities, with the new Article 26 including 28 new rules. The rules for Interconnection of Distributed Generation Facilities ("DGI Rules") establish mandatory technical standards, processes, and timelines for utilities to use for· interconnection and parallel operation of different types of distributed generation ("DG") facilities; customer and utility rights and responsibilities; provisions for disconnection of DG facilities from the distribution system; specific safety requirements; more flexible standards for electric cooperatives; a reporting requirement; and a requirement for each utility to create, submit for initial approval and submit for approval periodically and when revised, and implement and comply with a Commission-approved Interconnection Manual.

The first dozen pages are basically legal stuff.  The document defines how an utility must review, then accept/reject/etc. an application to connect distributed generation to the utility.  It defines both customer rights and utility procedures.  There are a lot of utility, installer and customer comments along with the ACC staff recomendations.

Utility Information


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

 

Tucson Electric Power (TEP) plans to provide more than 70 percent of its power from wind and solar resources as part of a cleaner energy portfolio that will reduce carbon emissions 80 percent by 2035.

TEP has filed its integrated resource plan (IRP) with the Arizona Corporation Commission, outlining plans for 2.5GW of new solar and wind over the next 15 years and 1.4GW of energy storage capacity as it progressively shutters its coal power stations.

See the TEP Press Release for more information: https://www.tep.com/news/tep-plans-clean-energy-expansion-carbon-reduction/

TEP customers intending to install a new PV system now need to check that their system can be safely installed and connected to TEP’s grid.

TEP now has service areas that are saturated with PV systems where new PV systems are subject to additional review and requirements under Arizona’s Distributed Generation Interconnection Rules. TEP has prepared DG Saturation Maps showing these areas.

This further described at https://www.tep.com/get-started-with-solar/

This requirement stems from the recent Distributed Generation Interconnection Rules issued by the Arizona Corporation Commission.

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...
