Big Win For Solar Revolution, Public as Nevada Reinstates Net Metering

Back during late 2015 and early 2016, wealthy investors aligned with Nevada utilities in an attempt to kill off a wave of rooftop solar adoption rippling through the state.

Campaign money was promised, shady back-room deals were made, and in 2016, the state set forward a policy that would basically make it uneconomical for homeowners to purchase or maintain solar rooftops. Credits to homeowners with solar roofs who sold electricity back to utilities dropped from 12.5 cents per kilowatt hour to 2.5 cents.

This crushing blow to clean, distributed energy resulted in mass protest both from the Nevada public and from the industry itself. Demonstrations erupted in the Nevada capital as Solar City (now under Tesla), Sunrun, and Vivint all decided to pull the plug on state operations in an all-out boycott to protest Nevada’s anti-renewables policy. In total, 2,600 clean energy jobs were lost in Nevada as industries fled the state and solar adoption rates plummeted.

Many thought this was the short-term end for rooftop solar in Nevada. That residents wanting to tap the abundant, clean power source would have to wait for battery prices to drop enough for them to go off-grid. But since 2016, it appears that the Nevada government has now had a change of heart in the face of a powerful counter-lobbying campaign by the solar industry, progressive politicians, and the public. For yesterday, both Governor Sandoval and the state legislature reinstated a net metering policy that is far more benevolent to homeowners with solar roofs and the solar industry at large.

It’s worth noting that the new policy makes far better sense for Nevada — which has no fossil fuel resources to speak of, but possesses an abundance of sunlight and is home to Tesla’s Gigafactory 1. And the fact that Nevada ever turned against renewables at all is a testament to the harmful influence fossil fuel based utilities are sometimes able to exert on state governments. But this effort to stymie renewables and home solar ownership ultimately failed.

Assemblyman Chris Brooks, a Democrat who spearheaded a clean energy push in Carson City provided this gauge of Nevada public sentiment in Scientific American:

“A lot of folks would say, and you would be surprised, ‘Las Vegas has so much sun; why aren’t we putting solar on every roof in Nevada? People across the state, from many different demographics, many different socio-economic situations, all said, ‘Why don’t we use more solar?’”

The newly reinstated policy will provide utility buy-backs for home solar generation at no less than 75 percent of the retail rate (or around 8-9 cents per kilowatt hour) and would be phased to allow new solar purchasers to receive higher payback rates during early years of ownership to help defray system costs. This policy stability ensures that homeowners who buy solar will receive a good return on their investment.

And it’s something politicians in the state are pretty proud of. Republican Governor Sandoval suggested that the program be a model for other states looking to incentivize renewable energy as the bill was signed.

“I believe, humbly, it will be a national model across the country.” he said to a crowd of solar advocates at the signing ceremony. “I’m as competitive as it gets, and I want Nevada to truly be a leader in energy policy.”

Kauai Shows Solar + Storage is Starting to Become Cost Competitive With Fossil Fuels, Nuclear

It wasn’t too long ago that the cost of an average solar energy power plant was above 10 cents per kilowatt hour and the world was raving at the low prices for Middle East solar generation in the range of 6 cents per kilowatt hour. At that time, to the shock, awe, and dismay of many, solar began to become earnestly competitive with traditional power plants based on price of energy alone.

Base Wind + Solar Now Cheaper Than Fossil Fuels, Nuclear

But it’s amazing what a difference just two years can make. Now solar prices have fallen into a range of around 4-6 cents per kilowatt hour with the least expensive solar plants now hitting as low as 2-3 cents per kilowatt hour. These prices are now far less than diesel and nuclear based generation (in many cases 1/2 to 1/4 the price of these systems) and today even out-compete coal and gas fired generation.


(Research by Lazard now shows that wind and solar are less expensive than all forms of fossil fuel and nuclear based energy. Image source: Lazard and Clean Technica.)

For as you can see in the image above, the cost of new natural gas generation now ranges from 5 to 8 cents per kilowatt hour for the least expensive plants and the price for new coal generation ranges from 6 to 14 cents per kilowatt hour. Utility wind and solar, by comparison, now ranges from 3 to 6 cents per kilowatt hour in most cases.

These, far more competitive, prices for renewable energy based systems provide a very strong case for the base market competitiveness of renewables. One that supports a clear rational economic argument for rapid integration of renewable energy systems. A strong economic case that can now be made even when one doesn’t include the various harmful externalities coming from nuclear energy and fossil fuel based power or the related and continuously worsening climate crisis. Renewable energy detractors, therefore, can now no longer make an argument against clean energy sources based on price alone. As a result, the argument against more benevolent energy systems during recent months has tended to shift more and more to the issue of intermittency.

Facing Down Fears of Intermittency

As an example, in its most recent report on the cost of global energy, the typically pragmatic Lazard Consulting group recently noted:

Even though alternative energy is increasingly cost-competitive and storage technology holds great promise, alternative energy systems alone will not be capable of meeting the baseload generation needs of a developed economy for the foreseeable future. Therefore, the optimal solution for many regions of the world is to use complementary traditional and alternative energy resources in a diversified generation fleet.

It’s a statement that moves the consultancy group closer to reality. One that opens wide the door for a much needed rapid integration of clean energy supplies. But, as with the analysts who failed to predict the precipitous fall in solar prices and the related rapidly increased availability of renewable energy sources as a result, the Lazard report fails to understand the fundamental price and mass production supply dynamics now setting up. A dynamic that will likely transform the cost and availability of energy storage systems in a similar manner to those that acted to greatly reduce the price of solar energy systems during the period of 2011 through 2016. As a result, Lazard’s ‘not for the foreseeable future’ statement is likely to have a life expectancy of about 3-5 years.

Soft Limits

Wind and solar power generation systems do have the base limitation that they only produce energy when the wind is blowing or the sun is shining. Often, these energy sources have to be widely distributed and interconnected to cover a significant portion of demands coming from power grids (30 to 50 percent or more). And in the present understanding of energy supply economies, standby power or power storage systems have to be made available for the periods when majority renewable energy systems go off-line. All too often, this standby power generation comes from conventional sources like coal, gas, or nuclear.

That said, the underlying flexibility of renewable energy is starting to overcome the soft limit that is intermittency. And a recent report by the U.S. National Renewable Energy Laboratory found that as much as 80-90 percent of grid electricity demand could be met by widely distributed renewable energy sources such as wind and solar as soon as 2050 so long as an advanced grid and related energy storage systems are developed.

In order to meet the challenge of transitioning most or all electricity based energy supply to renewables — not only does the cost of renewable energy need to be competitive with fossil fuels, but the cost of intermittent renewable energy + the systems that store them must be similarly competitive. Fortunately for those of us concerned about the growing risks posed by the global climate crisis, it appears that we are now entering a period in which exactly this kind of cost competitiveness for integrated renewable + storage systems is starting to emerge.

Solar + Battery Storage Becoming Cost Competitive

Last year, the Hawaiian Island of Kauai purchased a ground-breaking solar + battery storage system from Tesla and Solar City. The system paired solar panels with Tesla power packs to provide 17 megawatts of solar energy and 10 megawatts of battery storage in order to replace about 10 percent of the island’s expensive diesel electricity generation.


(Tropical Kauai aims to be powered by the sun. In doing so, it’s starting to shift away from dirty and expensive energy derived from coal and diesel generating plants. Image source:

On Kuaui, diesel generation costs about 22 cents per kilowatt hour. Expensive fuel and equally expensive heavy machinery must be shipped from far-flung locations to the remote island. And this adds to the overall cost of fossil fuel generation. During 2016, Solar City and Tesla significantly out-competed the price of diesel generation by offering its solar + storage generating system for 13.9 cents per kilowatt hour — a cost that was comparable to the more expensive versions of nuclear, coal, and gas fired generation plants the world over.

Fast forward to early 2017 and another solar + storage provider was being contracted to add still more renewable based electrical power to Kauai’s grid. AES Distributed Energy is now contracted to build 28 megawatts of solar photovoltaic panels mated to 20 megawatts of battery based storage. The price? About half that of diesel-fired power generation at 11 cents per kilowatt hour.

This is about 20 percent less than the Solar City + Tesla offering just one year later. A system that hits a price comparable to mid-range coal and nuclear generation systems. And, more to the point, AES’s solar panels + battery packs will enable Kuaui to produce 50 percent of its electricity through renewable, non-carbon-emitting sources.

Renewables + Storage to Beat Fossil Fuels in Near Future

Compared to the cost of renewable energy, the price of batteries is still comparitively expensive — effectively doubling the price of base solar. However, widespread adoption of battery-based electrical vehicles is helping to both rapidly drive down the cost of batteries and to provide a large global after-market supply of batteries useful for storing energy. By 2017, it’s likely that about 50 gigawatts worth of energy storage will be sold on the world market in the form of electrical vehicle batteries. By the early 2020s, this number could easily grow to 150 gigawatts of storage produced by the world’s clean energy suppliers every year.


(Global lithium ion battery production is expected to hit more than 120 GW and possibly as high as 140 GW by 2020. This production spike is coming on the back of newly planned battery plants in China, the U.S., and Europe. Presently, the largest plant currently operating is LG Chem’s China facility which was completed in 2016. Tesla’s Gigafactory is already producing batteries and is expected to ramp up to 35-50 GW worth of annual production by 2018-2019. Volkswagen has recently announced its own large battery plant to rival Tesla’s Gigafactory [not included in chart above]. FoxConn, BYD, and Boston Power round out the large projects now planned or underway. Image source: The Lithium-Ion Megafactories Are Coming.)

As electrical vehicles are driven, the batteries they use lose some of their charge. However, by the time the life of the electrical vehicle is over, the batteries still retain enough juice to be used after-market as energy storage systems. Meanwhile, the same factories that produce batteries for electrical vehicles can co-produce batteries for grid and residential based energy storage systems. This mass production capacity and second use co-production and multipurpose versatility will help to drive down the cost of batteries while making energy storage systems more widely available.

Though mass produced batteries represent one avenue for rapidly reducing the cost of energy storage systems mated to renewables, other forms of energy storage including pumped hydro, molten salt thermal storage, flywheels, and compressed air storage also provide price-competitive options for extending the effectiveness of low-cost variable power sources like wind and solar. And with the price of solar + storage options falling into the 11 cent per kilowatt hour range, it appears likely that these varied mated systems have the potential to largely out-compete fossil fuels and nuclear based on price alone well within the foreseeable future and possibly as soon as the next 3-5 years.

In Defiance of Harmful Fuels — Is Tesla/Solar City the New Model For What an Energy Company Should Look Like?

It could well be said that we are subsidizing our own destruction. Despite centuries of use, fossil fuels around the world today receive about 500 billion dollars annually in the form of economic incentives from Earth’s various governing bodies. With alternatives to fossil fuels becoming less costly and more widely available, and with the impacts of human-forced climate change growing dramatically worse with each passing year, such wasteful and harmful misuse of public monies is starting to look actively suicidal.

Fossil Fuel Funding for Global Catastrophe

Given so much money going into the hands of what are already the wealthiest corporations in existence, one would expect that the practice of providing these economic powerhouses with such a massive largess of public generosity would result in some kind of amazing overall benefit.

Energy itself is certainly a benefit. It allows for the rapid and easy transportation of groups and individuals. It lights up homes, powers machinery, keeps us warm in the winter and cool in the increasingly hot summers. But despite what the industry would like you to believe, fossil fuels themselves only represent a small fraction of the global energy available to human civilizations. And the kinds of energy fossil fuels provide is often in its lowest efficiency and most highly externally destructive forms.

What these deleterious industries instead provide is the dirtiest sources of energy in the world. Harmful energy whose particulate pollution alone results in the death of 7 million people each year. More deaths than warfare, more than natural calamities such as earthquakes, and more than even those two combined. That doesn’t even begin to add water pollution from practices like coal burning and fracking. Nor does it add in the ramping up of a global mass extinction event due to the pumping out of hothouse gasses at the rate of 13 billion tons of carbon every single year. A rate that is likely faster than during even the worst previous periods of hothouse extinction in all of Earth’s long geological past. Probably faster than during the Permian, and certainly faster than the last heat spurred mass die off — the PETM of 55 million years ago. A harmful emission that threatens to, by mid Century, wreck much of global civilization and ruin the prospects of all of the children of humankind, not to mention that of millions of species living on this planet.

(Arctic glacier melts under the heat of human-forced climate change as Ludovico Einaudi plays a haunting requiem. Fossil fuel burning has led us to this pass, and things are now about to get much worse. But, for some inexplicably immoral reason, we continue to pump billions of dollars every year into the very industries that are causing the trouble in the first place.)

As such, the fossil fuel industry produces the exact opposite of a public good and its very continued operation is a dire existential threat. One that grows worse each and every time any of us light up a fossil fuel fire. Back during the 1930s, at a time when the US was recovering from another destructive period of corporate excess, it was thought that a corporation should not exist unless it produced some form of benefit to civilization. So the question must be asked — why do the destructive fossil fuel industries continue to receive so much support from the political bodies of the world when the use of these fuels results in so much harm inflicted upon the very publics they are supposed to serve?

It’s not as if there aren’t any viable alternatives.

Tesla Plans to Merge With Solar City

One example of a corporation that could produce an amazing public benefit by speeding the transition away from harmful fossil fuels is Tesla. Since its inception, this auto company has dedicated itself to producing only electrical vehicles. And it was the first Western company to do this successfully on a large scale despite a massive opposition coming from the fossil fuel special interest political and economic bodies themselves.

The reason for such opposition is due to the fact that the electric vehicle represents the potential to radically transform the way people across the world use energy. The electric motors and batteries that drive electric vehicles are themselves 2-3 times more efficient than fossil fuel based internal combustion engines. So even if the global EV fleet were powered by fossil fuels, it would result in less overall fossil fuel demand.

But an EV can be charged by anything, including wind turbines and solar panels. And this mating of battery powered vehicle with these two sources provides an amazing opportunity for individuals to dramatically reduce fossil fuel use yet again. Finally, the batteries produced in electrical vehicle manufacturing can be used, after and during their use in cars, as a device to store renewable energy produced in homes, commercial buildings or cities.

Energy Storage Tesla

(Tesla has long marketed itself as an energy storage provider. Its expanding battery supply chain, increasing reductions in battery cost, and recent proposed merger with Solar City provides the potential for Tesla to provide fully integrated renewable energy systems. Image source: Tesla Motors.)

The average home in the US uses about 10 kilowatt hours (kwh) of electricity on any given day. The Tesla Model 3 will come with a 60 kwh battery pack. Fully charged, this battery could power a home for nearly a week. But just sitting in the garage or driveway, the vehicle could take in energy from rooftop solar panels during the afternoon and evening hours, and with the simple application of some smart electronics and software, provide that energy back to a home during the night.

It’s an integrated system that largely can remove a person’s dependence on oil, gas, and coal for energy all in one shot. One that can reduce individual carbon emissions by 60 to 80 percent. And one that can result in greater systemic carbon emissions reductions if it becomes integrated into the full chain of manufacturing and transportation. And even more alluring is the fact that the more batteries are produced, the more solar panels that are sent down manufacturing lines, the lower the prices and the greater the public access to these energy transforming technologies. In such cases, it becomes more and more likely that an EV + solar combo will be supplemented by an inexpensive home battery capable of smoothing out times when the vehicle is not longer parked.

It’s a combination that the fossil fuel industry is apoplectic to prevent from hitting the market in a way that is broadly accessible. And, up until this point, there has never been one company that had the ability to integrate all these various systems in one go and under one roof. It’s a situation that changed yesterday when Tesla Motors offered to purchase Solar City.

Solar City Tesla

(The Solar City + Tesla merger has the potential to provide a number of integrated renewable energy solutions there were not previously available. EV charging stations mated with solar power generation is just one of many potential innovations that are likely to provide the opportunity to transition away from fossil fuel use. Image source: Clean Technica.)

The announcement came as CEO Elon Musk spoke of Tesla’s plans to fully solarize its network of charging stations. An innovation that would essentially begin to replace gas stations with solar and battery stations — and a huge step away from fossil fuels in itself. But the real transformative potential of the first fully vertically integrated renewable energy company in the form of Tesla + Solar City would be in its ability to provide single family homes with the potential to operate on renewable energy in a manner that is completely independent of any outside fossil fuel based source. And that, unlike oil, gas, and coal, is a public benefit that is entirely worthy of a government subsidy.

If You Live in Arizona, Salt River Project Wants You Shackled to Fossil Fuels For Decades to Come

Remove all the empowerment. All the individual benefit and pride that comes from owning your own energy-producing resource. Remove all the financial benefit — all of the increasing opportunities for middle class families to cut energy costs, to increase property values, and to expand their economic opportunities. Remove all the added benefit of expanding US energy independence — both for the US nation and for individuals.

Remove it all, and you still end up with the staggering singular opportunity that home solar energy generation provides — to cut individual and family carbon emissions through electricity generation to net zero.


(Solar neighborhoods like these are popping up all over Arizona. Monopoly utility Salt River Project wants to stop that through the imposition of fees. Image source: GOYO.)

It’s a staggering empowerment in that it gives each and every homeowner the opportunity to say no to a future in which the world is dragged further and further into a global warming nightmare. It’s a right. In essence, a basic human right, to be given a choice to avoid such a terrible outcome and to play a personal role in making responsible choices for the future benefit of ourselves, our spouses, our children.

And, just a few days ago, a major Arizona utility — the state-sanctioned monopoly Salt River Project — did everything they could to take that choice away from homeowners. To shackle them, for decades, to devastating, carbon-emitting energy sources.

The Salt River Project — Green Washed, Carbon Fueled

The Salt River Project is an old, mostly smoke-stack driven, utility. Having existed for more than 100 years, it now provides power for more than 1 million customers — primarily in the Phoenix metro area.

Of the power SRP generates, about 85 percent comes from dirty sources. Though hydroelectric dams are among its assets, though solar energy accounts for 120 megawatts of its generation, though wind accounts for about the same, SRP is primarily powered by fossil fuel sources. It owns stakes in nine massive fossil fuel generating stations — half of which are coal, the other half gas. As a result, SRP is responsible for many millions of tons of carbon emissions each year. All emissions it generates and dumps into the atmosphere — scot-free of costs for the harm it is continuing to inflict on the world’s atmosphere, oceans, glaciers, and weather.

Coal power plant SRP

(The Four Corners coal power plant and associated strip mine — one of many coal plants operated wholly or in part by SRP. SRP’s stifling of renewable energy adoption by homeowners would ensure the continued use of dirty plants like this for decades to come. SRP pays nothing for the harm plants like these inflict on the global climate system. Image source: High County News.)

But all this damage doesn’t come without its own share of greenwash. The Salt River Project touts goals of reaching 20 percent renewable capacity by 2020. It also hosts a home solar project which funds 12.5 megawatts of solar energy capacity for the current year (May 1 2014 to April 30 2015). A rate of adoption that would take 300 years to remove its fossil fuel generation even if energy consumption levels remained flat.

At best, given the amazing achievements of renewable energy on cost, ease of use, and access (especially for wind and solar), the energy transition efforts by Salt River Project (SRP) can be described as foot-dragging. An effort far too paltry and slow to be an effective mitigation to the damage resulting from human-caused climate change.

The glacial pace of energy transition for this massive utility is bad enough on its own. But, even worse, SRP has leveled one of the most heinous attacks on individual renewable energy ownership now ongoing in the United States. And it is with this action that it has basically nullified even the paltry progress it has made toward reducing carbon emissions from its own generation sources.

A State-Supported Monopoly Assaulting Home Solar Ownership

For as of this year, SRP has decided to levy a $50 monthly fee (we could well call it a fossil fueled tax of 600 dollars per year) on home solar owners for use of grid services. The fee directly targets home solar users for discrimination, penalizing them for their choice of power source.

The fee is so high as to have stifled solar energy adoption in the Salt River Project territory. Last year, users in the SRP grid region installed nearly 40 megawatts of home solar energy (four times that proposed by SRP). This year, installations could have hit as high as 60 megawatts or more — equaling half the total SRP solar generation capacity installed within just one year.

But rumor of the fee alone was enough to snuff out new solar adoption. The monthly rate of installation swiftly fell from more than 600 homes per month last year, to less than 10 per month this year.

Though Salt River Project is not alone in adding ‘grid maintenance fees’ for solar energy users, it is the first to set the fee high enough to stifle solar energy adoption. Other fees range from 5-25 dollars per month — well less than half what SRP charges and the net effect has not been so great as to reduce solar adoption. Arizona Public Service, for example, leveled a 5 dollar fee and home solar adoption has continued at the rate of nearly 8,000 per year in its region of control.

Homeowners in the SRP region simply have no other choice. SRP is the only grid services provider. And its policies, as a government-private partnership, are sanctioned by Arizona state legislation. SRP has thus used its monopoly status to snuff out individual solar adoption in its area of operation. And this, in itself, is an egregious stifling of the individual rights of energy choice and energy freedom.

Lawsuits, Massive Public Backlash

Salt River Project’s suppressive action is already very unpopular. At the board meeting in which solar fees were assigned an angry crowd of over 500 people gathered. As SRP announced decisions on solar fees, they were met with loud boos from constituents.

But the stifling of public solar adoption hasn’t just inflamed the grass roots — it’s also bringing some of the heaviest hitting solar corporations and public alliances into the ring. Today, Elon Musk’s Solar City Corporation joined Solar Alliance (a solar interest consortium) in suing SRP for anti-trust violations. The Solar City statement is one of historic significance and reads as follows:

Last Thursday, [SRP] approved a new pricing plan designed to punish customers who choose to go solar. Under the new plan, SRP customers who generate their own power have to pay additional ‘distribution charges’ and ‘demand charges’ that other SRP customers do not. These discriminatory penalties add up to hundreds of dollars per year, and make a competitive rooftop solar business impossible within SRP territory . . . SRP has sabotaged the ability of Arizona consumers to make this choice if they happen to live in SRP territory. We can already see the intended effects: After the effective date of SRP’s new plan (December 8 of last year), applications for rooftop solar in SRP territory fell by 96%. (Emphasis Added).

Recent filings by Solar City and Solar Alliance are likely the first of many. For SRP’s action is so egregious as to materially impact anyone who previously desired or planned to install solar, effectively removing their economic ability to do so.

Such removal of choice is anti-competitive by nature and will likely end up with SRP facing off not only against environmentalists, Tea Party activists interested in individual energy choice, solar leasers, installers, financiers and homeowners alike, but also against the US Department of Justice’s Anti-Trust Division.

Like SRP, many utilities hold but often do not so punitively wield monopoly powers over their regions of control. The current struggle by SRP to suppress home solar energy adoption highlights a potential abuse of power by many utilities going forward. Utilities are, therefore put on notice, solar energy providers and users will not be bullied by fossil fuel special interests into reducing adoption rates. Any actions to suppress adoption are anti-competitive and amoral. They will be challenged accordingly.
