6 candidates debate for positions within the Arizona Corporation Commission

The Arizona Corporation Commission (ACC) has posted STAFF'S THIRD REVISED PROPOSED DRAFT RULES (DOCKET no. RE-00000A-18-0284) That lay out a clearer framework for Electric Utilities to report their compliance with the proposed standards for the Renewable Energy Standard, Clean Peak Standard, Distributed Renewable Storage Requirement, and Electric Vehicle Infrastructure.

See the ACC Staff Report: docket.images.azcc.gov/E000004960.pdf

ACC Staff has made substantial changes to the draft rules that were filed on July 2, 2019 based on feedback received at each workshop held in this matter, comments to the docket, and a review of relevant energy policies across the United States.

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. 

This is a good report that provides a conceptual framework for the Statewide Transportation Electrification Plan for Arizona, including planned or proposed near-term utility actions to support the growth of Electric Vehicles (EVs) in the state.

The report is part of a filing on the Arizona Corporation Commission website: Arizona Statewide Transportation Electrification Plan

The City of Phoenix is now (January 2020) requiring a special permit from the Fire Department for most solar systems and batteries.  The fees and required plans varies with size and content.  See this link for an application and details:  https://www.phoenix.gov/firesite/Documents/Solar Photovoltaic OTC Bundle Rev 01-2020.pdf

This is in addition to a building permit from the Planning & Development Department and must be separately obtained at a different address (150 South 12th Street) or on-line via the above link. Also noted is that residential PV permits are no longer over the counter and as of March 2020 are estimated to take 29 working days to process.  Separate inspections are required.

The code requirements are contained in Phoenix-Chapter 12 BESS R-3-1.pdf

Also note: All Phoenix solar building permits are now electronic submittal only. Contact the Electronic Plan Review (EPR) Triage Team at 602-534-5933 or epr.support@phoenix.gov. For more information on EPR, visit us at https://www.phoenix.gov/pdd/onlineservices/electronic-plan-review.

The US House passed the Moving Forward Act, H. R. 2, on July 1, 2020. The US$1.5 trillion infrastructure support bill includes a raft of measures in support of America’s clean economy. The bill proposes to extend the solar Investment Tax Credit (ITC) scheme to 2025. Major resistance is expected in the Senate.

Update August 4th: 07/20/2020 Senate Received in the Senate.  No action since.  Call your Senators!

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...

Update July 18, 2020

APS has posted a Final report on the McMicken Battery Energy Storage System Event Technical Analysis and Recommendations.

See the full article:  https://azsolarcenter.org/update-utility-solar-battery-fire-in-arizona 

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.
