Location: Scottsdale Granite Reef Senior Center, 1700 N. Granite Reef Road (northwest corner of McDowell and Granite Reef, behind the convenience store)
Since electric lights first appeared in buildings, the electrical grid and buildings have had an important relationship. To date, the relationship has been one-sided - the grid provides electricity and buildings have been passive consumers.
Renewable energy coupled with energy efficiency provides multiple benefits including distributed (decentralized) energy, lower energy costs and reducing the need to build more electric power plants. Energy efficiency alone is among the most cost-effective ways to reduce carbon emissions, making it a part of fighting climate change. Hear about the role you can play in this transformation to reduce environmental impacts and improve the prospects for a bright future with the buildings we live and work in.
Jeff Grout is a senior energy consultant and project manager who has been working on energy efficiency projects with large commercial and industrial customers in Arizona for over 10 years. His experience includes many energy efficiency projects, energy audits and working on demand response and demand side management programs with major utilities from coast to coast. As an active participant in the clean energy revolution, his current dream is to see Arizona become the solar power leader that it is destined to be.

Interconnection Application Checklist
The checklist used to review applications has been revised to include RCP qualification criteria, and is attached for your convenience. Please use this tool to ensure applications meet the qualifications and Interconnection Requirements for expeditious approval.
In order to qualify for RCP (see RCP requirements above), customers installing solar systems over 10 kW DC on a newly constructed home that does not have established usage history will need to provide load calculations stamped by an Electrical Professional Engineer in Arizona. These load calculations will need to be uploaded to the application under the document type “New Build Load Calculations”.
Resubmittals After Approval
In order to continue our efforts to streamline the application review process, applications that have new diagrams submitted after approval (i.e. change in equipment and new diagrams are uploaded) will need to be canceled and a new application will be required. The new application will be subject to the rate rider in effect at the time the complete application is submitted. This change is effective immediately. (See below, APS has extended this) Applications with resubmittals prior to today will continue to be manually processed.
Saver Choice Tech Plan Qualification (Formally known as R-Tech)
The Saver Choice Tech Plan Qualification application will be available online August 22, 2017. Customers interested in this experimental rate can apply if they meet the requirements.

The must-see panel of Intersolar North America (if you could only see one) discussed the most pressing issue in distributed solar today: What’s happening with net metering – and where does the industry go from here?
At 9 am on Tuesday morning, one of the most important issues in the industry was being debated in a conference room as part of the Intersolar North America trade show: net metering.
Across the nation, net metering policies are changing. The largest solar market, California, has moved to a successor policy, while other states including Hawaii and Indiana have shut the policy down entirely.
But looking beyond the more severe instances, an exploration of different states shows a definite shift in the direction of policies that attempt to put a more precise value on the electricity exported to the grid by distributed solar, along with a move to time-of-use rates. And more often than not the shift is more incremental than a step-change.
The assembled experts attempted to grapple with these big-picture issues, fragmented as they are in the individual experiences of different states.

The net-metering battle has begun, as utilities across the US are lowering the price they are willing to pay for customer-generated electricity from solar. I am predicting a series of solar wars in the near future. They will be mainly between the existing monopoly electric utilities and the solar industry that is involved with behind-the-meter solar installations. Utilities are not against solar, as this new technology gives them another method to meet electricity demand, but what utilities dislike is their customers producing their own electricity by any means such as solar, wind, or other on-site generators. It means customers purchase much less energy from the utilities.
Up until about 2005, the United States was the leader in solar electric installations, but other countries such as Germany have become larger players. As we can see on the graph, solar was not growing much in the US until about 2011-2012.
This surge in solar installations starting in 2011 has created this first solar battle about net-metering. Before 2012 utilities in the USA had no reason to see solar as a threat to them, as the amount of revenue lost to customer self-generation was extremely small. So during this timeframe, utilities did not mind giving customers full retail credit for their excess energy.
Net-metering typically occurs between 10 am and 4 pm when a customer’s solar system is producing more electricity than the onsite loads require: the sun is shining and the occupants are off at work. This “extra” energy is sent back through the utilityowned meter and into the grid; typically, it amounts to about 20-30% of the electricity produced by the solar system.
Net-metering means full retail credit for one’s excess energy; your bill would have it energy usage reduced, and if your usage goes negative, then you get a rollover credit for you next month’s bill. The battle is about the utilities wanting to change this credit on customers’ bills so that it’s lower than the retail rate of electricity. This has started discussions about the concept of “the value of solar” for utilities in many states.
Many utilities were startled after 2012 by the large increase in rooftop solar installations. In many locations this lost revenue was still not significant, but the growth and trends were disturbing.
Utilities are regulated on a stateby-state basis by their respective public utilities commissions, or PUCs.
The first three states to enter into the net-metering battle were California, Arizona and Nevada, due to excellent solar insolation and relatively high electric rates. Earlier this year, in California, the PUC rejected any changes to net-metering, while in Nevada the PUC allowed the utility NV Energy to reduce its credit to customers by 75% reduce how much they credit consumers bills by 75%.
The Nevada decision is still being altered and reviewed, but Solar City, one of the nation’s largest residential installers, has left Nevada due to this PUC decision.
What happens next in the net-metering battle?
We had an electricity war over 100 years ago – the current wars. This battle was between Thomas Edison and George Westinghouse: Edison wanted a direct current grid, while Westinghouse fought for alternating current. This war was fierce and very public, as the solar wars are becoming today. Nikola Tesla’s patent for the inductive motor was the innovation needed to help decide the “war of the currents.” Inductive motors work with AC, not DC, so when Westinghouse licensed Tesla technology he was able to defeat Edison, and now we have the AC electric grid. Free markets today are helping to decide our solar war about net-metering. This free market competition in the solar industry has brought down the cost of solar-generated electricity to under 3 cents per kwh.
We are seeing innovation in the energy storage space. Remember the typical residential solar system only nets back to the grid about 20-30% of its production. Most of the electricity produced by a solar system is consumed directly in the home. The reason this is important is that to effectively eliminate net-metering back to the grid, you don’t need a lot of storage. Could it be a strange twist of fate that the company called Tesla can use technology, just as the firm’s namesake Nikola Tesla did, to decide this battle in energy?
The short-term impacts of the net-metering battle will adversely affect residential solar installations in the United States. This will happen on a state-by-state basis, depending on the political leanings of each state’s PUC. Here are some of states that are either in, or may soon enter, the net-metering battle: Arizona, Nevada, Maine, Florida, and Alabama.
The biggest short-term loser may be Sun Power due to its exposure to the United States residential market, and its weak cost structure as mentioned in my last article on solar.
The longer term impacts on the solar industry are much more interesting. This net-metering battle is driving innovation in the energy storage and inverter space. Tesla has already announced that it will develop the solar roof and its own inverter/storage technologies. Tesla is buying Solar City, so the combination of the two firms can continue to innovate to eliminate the need for net-metering.
In my opinion within a few years, all residential solar installations will have storage, smart inverter, and curtailment control. In this case with no electricity being passed to the utilities equipment and grid, customers will not even need to notify their utility of their new solar system – or ask for “approval.”
With these longer term impacts in mind, I see this as a positive for several companies: Enphase Energy , Solaredge Technologies, Tesla, and Aquion Energy. All these firms are spending money on research and development on smart energy storage, and have shown to be quite innovative. I do see a technological battle between lithium ion battery and aqueous flow type technology in the near future.
