Solar power in Arizona

{{short description|Overview of solar power in the U.S. state of Arizona}}

File:CSP prospects for the SW USA (3% slopes).jpg

Solar power in Arizona has the potential to, according to then-Governor Janet Napolitano, make Arizona "the Persian Gulf of solar energy". In 2012, Arizona had 1,106 MW of photovoltaic (PV) solar power systems, and 6 MW of concentrated solar power (CSP), bringing the total to over 1,112 megawatts (MW) of solar power. As an example, the Solana Generating Station, a 280 MW parabolic trough solar plant, when commissioned in 2013, was the largest parabolic trough plant in the world and the first U.S. solar plant with molten salt thermal energy storage.{{cite web|url=https://www.computerworld.com/article/2485916/u-s--flips-switch-on-massive-solar-power-array-that-also-stores-electricity.html|title=U.S. flips switch on massive solar power array that also stores electricity|last=Mearian|first=Lucas|website=Computerworld|date=October 10, 2013|access-date=July 10, 2021}}

A Renewable Portfolio Standard set by the Arizona Corporation Commission requires 15% renewable energy by 2025 among regulated utilities, 4.5% of which must come from distributed renewable energy sources.

History

File:Solar array asu.jpg

The first commercial solar power system in the state was a 95 kilowatt (kW) single-axis tracking photovoltaic plant in Flagstaff, Arizona, opened in October 1997 and operated by Arizona Public Service (APS).{{cite web|url=https://www.bizjournals.com/phoenix/stories/1997/05/05/daily7.html|title=First solar energy plant planned for Arizona|newspaper=American City Business Journals|date=May 8, 1997|access-date=July 10, 2021}}{{cite web|url=https://www.businesswire.com/news/home/20131001005575/en/APS-Solar-Plant-in-Flagstaff-Celebrates-%E2%80%9CSunny-Sweet-16%E2%80%9D|title=APS Solar Plant in Flagstaff Celebrates "Sunny Sweet 16"|publisher=Business Wire|date=October 1, 2013|access-date=July 10, 2021}} In 1999, the city of Scottsdale covered an {{convert|8500|ft2}} parking lot with photovoltaic panels, to both provide shaded parking, and generate 93 kW of solar power. In 2001 APS and Embry-Riddle Aeronautical University constructed a 190 kW single-axis tracking photovoltaic power plant.

In 2001, the Springerville Generating Station Solar System was built by Tucson Electric Power, one of the first large scale photovoltaic power stations. Originally 4.6 MW, it has been expanded to 6.4 MW.{{Cite web|url=https://www.tep.com/careers/springerville/|title=Springerville Employee Enjoys Connections and Community|website=Tucson Electric Power}}{{Cite web|url=http://www1.eere.energy.gov/solar/review_meeting/pdfs/p_20_moore_snl.pdf|title=Five Years of Operating Experience at the Springerville PV Generating Plant}} In 2002, Love Field Airport, in Prescott, Arizona, began construction of a 5 megawatt (MW) photovoltaic power plant. By July 2006, it had a peak capacity of 2.879 MWAC.{{Cite web|url=http://www.aps.com/my_community/Solar/Solar_22.html|archiveurl=https://web.archive.org/web/20070717134226/http://www.aps.com/my_community/Solar/Solar_22.html|url-status=dead|title=APS Solar Power Plants|archivedate=July 17, 2007}}{{Cite web|url=http://www.aps.com/_files/renewable/SP002PrescottAirport.pdf|archiveurl=https://web.archive.org/web/20090419094537/http://www.aps.com/_files/renewable/SP002PrescottAirport.pdf|url-status=dead|title=Prescott Airport Solar Power Plant|archivedate=April 19, 2009}}

The two operating concentrated solar power plants are the 1 MW Saguaro Solar Power Plant completed in 2005, the first commercial CSP plant of the 3rd millennium, and a 5 MW solar trough system at the University of Arizona Solar Tech Park project which was completed in 2011.[http://www.nrel.gov/csp/solarpaces/project_detail.cfm/projectID=84 UA Tech Park Thermal Storage Demonstration Project] The 280 MW Solano Generating Station is under construction.

Historically, Arizona has had one of the most successful solar incentive programs in the United States. However, as of February, 2013, the Arizona Corporation Commission has completely eliminated commercial incentives and has severely reduced the amount of residential incentives available.{{cite web | url= http://www.clearskyadvisors.com/3265/ready-or-not-arizona-takes-steps-toward-incentive-free-solar/|title= Arizona Takes Steps Towards Incentive Free Solar|date=March 13, 2013|publisher=ClearSky Advisors | author= Mark Bissegger|access-date=2013-03-18}} Still, some of the country's largest solar providers continue to do business in the state, including the largest solar contractor in the US, First Solar.{{Cite web|url=https://www.solarpowerworldonline.com/2013/10/solar-power-world-top-250-top-contractors-arizona/|title=The Solar Power World Top 250: The Top Solar Contractors In Arizona|first=Frank|last=Andorka|date=October 1, 2013|website=Solar Power World}}

Community solar farms

{{main|Community solar farm}}

Arizona has two community solar farms. Tucson Electric Power has a 1.6 MW community solar farm southeast of Tucson. Consumers can purchase 150 kWh for about $3/month. The 227 kW Trico Sun Farm in Marana allows Trico customers to purchase solar panels in one quarter increments for $920, and receive a credit of the output, about 36 kWh, each month for 20 years, worth about $5.{{Cite web|url=https://tucson.com/news/local/northwest/trico-customers-can-buy-power-from-sun-farm/article_15f524cc-8d71-54ba-a058-e8189a273054.html|title=Trico customers can buy power from 'sun farm'|first=Shelley Shelton Arizona Daily|last=Star|website=Arizona Daily Star|date=24 March 2011 }} Customers can purchase up to their average usage for the last 12 months, up to 10,000 watts.{{Cite web|url=http://www.trico.coop/documents/SunWatts%20Sun%20Farm%20FAQ_Final_03092011.pdf|title=SunWatts Sun Farm FAQs}}

Net metering

As of June 2021, Arizona was served primarily by Arizona Public Service company, Tucson Electric Power and UniSource Energy Services.{{cite web|url=https://tucson.com/lifestyles/home-and-garden/rosie-on-the-house-tips-so-tep-customers-can-stay-cool-save-money/article_77939e48-cdf3-11eb-8c7a-fb4040edf0d8.html|title=Rosie on the House: Tips so TEP customers can stay cool, save money|last=Romero|first=Rosie|newspaper=Arizona Daily Star|date=June 17, 2021|access-date=July 10, 2021}}

In 2008, Arizona had one of the most consumer-friendly net metering laws in the country. Excess generation is rolled over month to month, and any surplus was returned annually to the consumer at the avoided cost rate.{{Cite web|url=http://www.dsireusa.org/library/includes/incentive2.cfm|archiveurl=https://archive.today/20120801014751/http://www.dsireusa.org/library/includes/incentive2.cfm?Incentive_Code=AZ24R&state=AZ&CurrentPageID=1&RE=1&EE=1|archive-date=2012-08-01|url-status=dead|title=Arizona Net Metering}} IREC best practices, based on experience, recommends perpetual roll over of kWh credits.{{Cite web|url=http://irecusa.org/wp-content/uploads/2011/01/ASES-2009-Paper-0131-net-metering-and-IC-best-practices-1.pdf|title=Net Metering and Interconnection Procedures Incorporating Best Practices}} Arizona had 642 MW of rooftop solar in 2015.[https://www.wecc.biz/Reliability/2016%20SOTI%20Final.pdf 2016 State of the Interconnection] page 10-14 + 18-23.

Renewable Portfolio Standard

{{main|Renewable portfolio standards in the United States}}

The Arizona Renewable Portfolio Standard calls for 15% renewable energy by 2025, and 4.5% (30% of that) from distributed generation from renewable sources.{{cite web|url=https://cleantechnica.com/2018/05/29/the-states-of-distributed-solar-2017-update/|title=The State(S) Of Distributed Solar — 2017 Update|last=Farrell|first=John|website=CleanTechnica|date=May 29, 2018|access-date=July 10, 2021}} Renewable Energy Certificates (RECs), may be purchased to meet the requirement.{{Cite web|url=http://www.dsireusa.org/library/includes/incentive2.cfm?Incentive_Code=AZ03R&state=AZ&CurrentPageID=1&RE=1&EE=1|archiveurl=https://web.archive.org/web/20080414191115/http://www.dsireusa.org/library/includes/incentive2.cfm?Incentive_Code=AZ03R&state=AZ&CurrentPageID=1&RE=1&EE=1|url-status=dead|title=Renewable Energy Standard|archivedate=April 14, 2008}}

Arizona Solar Business Directory

The Arizona Solar Business Directory[http://www.meetup.com/arizona-solar-power-society/pages/Arizona_Solar_Buyers_Guide_and_Business_Directory/ Arizona Solar Business Directory] contains almost 100 solar installation companies that do business in Arizona and is maintained by the Arizona Solar Power Society. The business directory allows consumers and commercial customers to contact a number of different companies to get the best deal and best performing products in the solar industry.

Arizona Solar Watchdog Program

The purpose of the Arizona Solar Watchdog Program[http://www.gosolarinarizona.com/solar/arizona-solar-watchdog-program.asp Arizona Solar Watchdog Program] {{webarchive|url=https://archive.today/20120731101223/http://www.gosolarinarizona.com/solar/arizona-solar-watchdog-program.asp |date=2012-07-31 }} is to teach consumers how to check a solar installation contractor's license, credentials and work history. Every contractor in Arizona needs to be registered with the Arizona Registrar of Contractors (ROC).{{Cite web|url=https://roc.az.gov/search/node/clsc%20AZROCLicenseQuery|title=Search | Arizona Registrar of Contractors|website=roc.az.gov}} Each contractor is issued a Registrar of Contractors' license number, which can be looked up using the step-by-step process outlined under the Arizona Solar Watchdog Program.
