Worlds largest concentrated solar boondoggle is going out of business after just 11 years

 Ivanpah Solar Electric Generation System, the world's largest concentrating solar power plant with a rated gross capacity of 390 MW.

Post-modern temples to the Sun God

By Jo Nova

It was supposed to last 50 years...

The PR writers want us to believe the legendary Ivanpah has been beaten out by better cheap solar, and that this is somehow a “success”. But the truth is, it’s been killed by the same subsidies and crooked market that birthed it.

The Big Government Blob distorted the free market, and created a boom in solar power. But the business case was not that good, there was no miracle in the storage of electricity, nobody wanted fried birds, and the subsidies kept forcing more solar power generation in at the same useless time of day.

Since there were too many generators at lunchtime and not enough customers, the last surviving part of the free market has solved the imbalance.

Just another artificial boom and bust

In 2014, the project cost $2.2 billion dollars. Ivanpah has 173.000 heliostats, and theoretically could make 390 megawatts in a perfect moment. But no one in their right mind would have spent so much to get so little, so the government spent $1.6 billion taxpayer dollars as a “loan guarantee”.

I wonder how that is working out for the taxpayers, especially now that the capital depreciation has shifted from 50 years to 11.

11 years after a celebrated opening, massive solar plant faces a bleak future in the Mojave Desert

LOS ANGELES (AP) — What was once the world’s largest solar power plant of its type appears headed for closure just 11 years after opening, under pressure from cheaper green energy sources. Meanwhile, environmentalists continue to blame the Mojave Desert plant for killing thousands of birds and tortoises.

The Ivanpah solar power plant formally opened in 2014 on roughly 5 square miles of federal land near the California-Nevada border. Though it was hailed at the time as a breakthrough moment for clean energy, its power has been struggling to compete with cheaper solar technologies.

So it was struggling to compete with cheaper solar technologies, and yet, in a market where customers keep paying more and more all the time, it still couldn’t make money?

Even the Sierra Club didn’t like it:

“The Ivanpah plant was a financial boondoggle and environmental disaster,” Julia Dowell of the Sierra Club said in an email.

“Along with killing thousands of birds and tortoises, the project’s construction destroyed irreplaceable pristine desert habitat along with numerous rare plant species,” Dowell said. “While the Sierra Club strongly supports innovative clean energy solutions and recognizes the urgent need to transition away from fossil fuels, Ivanpah demonstrated that not all renewable technologies are created equal.”

Apparently the plant would sometimes blind drivers too. It certainly blinded investors.

The company did not reply to AP questions about what would happen to the giant industrial wreckage.

    By the time this monstrosity was completed, solar panel costs had come down to the point where it was cheaper.
    Also, Ivanpah needed to burn a few truckloads of LPG just to keep steam up until the sunrise each day.

      So it wasn’t so pure after all? I wonder who will pull it down and pack it away. Could it be used in the border wall? I was out around Wellington recently and saw several hundred acres covered in glass. Where will it end up ? And to think one coal plant could replace the whole thing and provide real power. Let’s hope Dutton has the courage to build one while we wait for a nuke or maybe we just build more coal and forget the nukes.

    Unless they had to create a closure plan as part of a permitting process, such as typical power plants are required to do, the facility will likely be abandoned. This has happened with the previous generation’s wind farms. If the facility represents a hazard, it will have to be demolished. With public money. It would be interesting to see if it is designated a RCRCA superfund site. Then, there would at least be an existing remediation process to follow.

      At the very least, the mirrors will represent hazards due to the possibility of blinding pilots and drivers and will have to be removed.

      This remediation work will be a work opportunity for all those woke Leftists doing useless or destructive “green” and other woke jobs who now find their useless jobs cancelled. They can work at minimum wage to help pay off their debt to society.

      Incidentally Ivanpah does not use molten sodium but other CSP’s do.

      When others shut down, the sodium, which is extremely hazardous, will need to be removed. It’s a nightmare to handle, especially in the vast quantities used, so will also be very expensive.

    The failure of projects like this means Australia will.be even more determined to go ahead with similar projects.

    Australia loves spending taxpayer money on failed technologies and harvesting taxpayer subsidies.

    Vast Solar Port Augusta Concentrated Solar Thermal Power Project

    Funded by ARENA $65m
    Total project cost $203m

    Summary
    The Vast Solar Port Augusta Concentrated Solar Thermal Power Project involves the development, construction and operation of a 30 MW / 288 MWh Concentrated Solar Thermal Power (CSP) plant at Port Augusta, South Australia.

    Start date 27 January 2023
    End date 31 May 2028

    It gets even worse because they want to make “green” hydrogen and methanol as well.

    The Australian Government and ARENA have also provided Vast Solar with $19.48 million in conditional funding through the co-operative HyGATE initiative with Germany. The funding supports Vast Solar’s Solar Methanol production plant, a 10 MW electrolyser producing green hydrogen for solar methanol production.

    And ARENA uses the US as an example, but these prijects are shutting down as per Jo’s article. They simply can’t survive without subsidies from the hard working people Donald Trump represents:

    https://arena.gov.au/renewable-energy/concentrated-solar-thermal/

    Concentrated solar thermal (CST) is a solar energy technology that uses sunlight to generate heat. Spain is the world leader in the use of CST to produce electricity, with around 2.3 GW in operation, followed by the United States with around 1.7 GW in operation.

    About Ivanpah’s subsidies:

    https://www.downsizinggovernment.org/ivanpah-time-end-subsidies

    Ivanpah in California is the world’s largest solar project. The project is owned by Google and NRG Energy, and is heavily subsidized by taxpayers. Ivanpah originally received a $1.6 billion loan from the Department of Energy (DOE) in 2011. Now the company is asking for another government subsidy to pay off its original loan.

    The company is asking the federal government to provide it with an enormous amount of cash to be used to payoff its debt to taxpayers. DOE actually requires Ivanpah to apply for a tax credit to aid loan repayment.

    The process is absurd. First, the government uses tax dollars to provide a loan guarantee to a risky firm. Then, it functionally forgives a large share of the outstanding balance after providing a large tax credit. This is an unjustified giveaway to investors in Ivanpah and a horrible deal for taxpayers.

    Energy subsidies have a long history of waste and mismanagement, but Congress ignores the record and keeps the money flowing. If approved, the Ivanpah tax credit would be another $539 million flushed down the drain.

    And if Goolag, one of the richest companies in the world, is a co-owner of Ivanpah, why do they need loan guarantees and other subsidies?

    David Maddison

    Goolag AI says this about the Spanish concentrated solar power projects:

    Spain previously offered significant subsidies for Concentrated Solar Power (CSP) through a “feed-in tariff” system, providing a fixed price per kilowatt-hour produced, which heavily incentivized CSP development, particularly between 2008 and 2012; however, due to cost concerns, the government later significantly reduced these subsidies, leading to a near standstill in the Spanish CSP market, with retroactive changes impacting existing projects and investor confidence.

    It must be bad if even fully woke Goolag AI doesn’t give it a glowing review.

    Another failure.

    More motivation for Australia and our leading chief “scientist” and “engineer” Chrissy “the simpleton” Bowen to throw more taxpayer money at failed technologies.

    A Solar Power Plant lasting 50 years? They are having a larf’. It would have probably needed replacement after 20 or so years. Was that cost factored in?

    Meanwhile, a well built modern HELE Coal Fired Power Plant or a modern Nuclear Energy Power Plant will last a lot longer than 50 years, all things being equal.

    Peter Dutton, you need to follow the lead of the QLD State Guv’ment who intend to keep all of their Coal Fired Power Plants.

      Most political opinions are industrial products.
      (It’s the reason something like 7 of the 10 wealthiest counties in the US surround Washington DC.)

      But ‘environmentalism’ got hijacked by ‘climate’.
      The ‘decarbonize’ scam was able to disguise itself as ‘environmentalism’.
      Really basic provocateurism to sabotage grassroots popular political power so the establishment faces no viable opposition.
      Similar to if you argue for vaccine safety, you’re labeled anti-vax.

      A really terrible period of political history.

        ‘environmentalism’ got hijacked by ‘climate’

        Bingo

        I’ve been saying forever that the ‘Green/Net Zero movement’ and the ‘Environmental movement’ are fundamentally incompatible.

        Greens want to raze forests for ‘biofuel’ (which burns dirtier than coal), plow under environments off all kinds to accommodate low-density energy sources like wind and solar (which require 40-100 times more land use than nuclear), and don’t give a tinker’s damn about wildlife endangerment related to their holy power sources, but feign concern for endangerment when it is caused by heretical fossil fuel infrastructure (just look at offshore wind versus offshore drilling). And don’t even get me started on the lack of concern over the ‘CO2 offset’ industry being almost entirely fraudulent. They don’t care if their religious indulgences are a sham, so long as they make them feel better.

        It’s similar to how the transgender movement is fundamentally incompatible with women’s and LGB rights. Women have to give up women’s spaces to dudes in dresses, gay kids are pressured to go through Iranian-style ‘conversion therapy’ so that they can become ‘trans-heterosexuals’, and lesbians are shamed for not wanting to have sex with ‘trans-women’ who are still packing one-eyed love muscles in their panties.

        Or how DEI race-essentialism has made racial tensions WORSE, not better, by making it clear to everyone that it is a zero sum game where people of no-color are discriminated against.

        Every leftist social movement accomplishes the opposite of what it claims to do.

      Streamers

      So many birds have been victims of the plant’s concentrated sun rays that workers referred to them as “streamers,” for the smoke plume that comes from birds that ignite in midair. When federal wildlife investigators visited the plant around 10 years ago, they reported an average of one “streamer” every two minutes.

      In Australia the Hazelwood power station was maliciously destroyed by the Andrews regime. Its cooling water pond contained introduced tropical fish and introduced barramundi (for fishing) and was a year-round refuge for humans and animals seeking warmth.

      Just before the communist Dictator Dan of Victoriastan destroyed it I went there specifically to have a last swim in it.

      The water was a constant 22C (71.6F).

      When Dan turned the power station off the water temperature dropped and all the fish died or were killed.

      Two species of tropical fish Tilapia mariae and Cichlasoma nigrofasciatum have established self-maintaining populations in the Hazelwood pondage. Both species are readily available in the local aquarium trade. Two temperate species also exist in the pondage, the introduced Cyprinus carpio and the endemic Retropinna semoni.

          Shortly before the Andrews regime vandalised Hazelwood Power Station they spent $150,000 of taxpayer money stocking it with barramundi.

          Thu 1 Dec 2016

          Barramundi were released into the warm waters of the Hazelwood power station pondage in April at a cost of $150,000.

          The tropical fish are usually only found in northern Australian waters, but the lake’s balmy minimum temperature of 22 degrees Celsius makes it an ideal southern home for the species.

          Fishing will start on Friday next week and is restricted by a ballot. A community open day will be held in February.

    When will people start talking about coal power? Thirty seven years of ‘dirty’ coal and no one in the West wants coal.

    In the UK, the government is sealing the existing gas fracking wells with concrete, to make sure no one ever uses them again. They used a fake earthquake scare for Theresa May to turn them off. Liz Truss tried to turn them on again but Rishi Sunak reversed it. So the UK is importing gas when it has plenty.

    It’s the same with coal power stations around the world being blown up, dismantled, buried, covered. Again to make sure that no matter how desperate people are, they have to use expensive power which doesn’t work.

    And all the money flows to China which is using its cheap massive coal power to take over the manufacturing world.

      It’s called Crescent Dunes.

      https://www.downsizinggovernment.org/crescent-dunes-another-green-flop

      Crescent Dunes: Another Green Flop
      Chris Edwards

      January 7, 2020

      The Department of Energy called the vast and expensive solar project a “success story” and “milestone for the country’s energy future.”

      But you can’t trust what the government says. Crescent Dunes is a flop and taxpayers are set to lose $737 million on it, according to a new Bloomberg report. That is even more than the $535 million taxpayers lost on the corruption-soaked Solyndra solar project.

      With 10,000 mirrors arrayed in the Nevada desert, Crescent Dunes does look cool. But with the much lower costs of solar photovoltaic and natural gas projects, the government’s gamble on this alternative technology was folly. Politicians never apologize for their mistakes, and the main politician responsible for this one, former Senator Harry Reid, has retired and won’t face any tough questions about wasting our money.

      Crescent Dunes was apparently undermined by mismanagement, unreliability, and excessive costs. The various players are now pointing fingers of blame at each other, which is typical of government-funded projects because they tend to diffuse responsibility.

      Another solar-array boondoggle is the Ivanpah project in California, which received $1.6 billion in federal money. It generates less energy than was promised and at very high costs. I discuss other failed federal energy projects in this essay.

      The lesson is that political daydreams about green new deals ultimately need to confront reality. And the reality is that the government’s track record at guiding our energy future has been pretty dismal.

    I am making guesstimate of 500GWh/yr average output over 11 years to total 5.5TWh. Amortising the capital of $2.2bn over that output gives $400/MWh. And that is just the capital. No O&M, no lost opportunity of the money, no repairs, no compensation for the environmental destruction and no removal cost.

    QLD is proud to announce that not to be outdone by the yanks, we also have our own failed concentrated solar array out in the desert which failed spectacularly years ago after relieving the taxpayer of at least $4,500,000.

    It died because of lack of maintenance, being so far from the bright lights that no one with the expertise wanted anything to do with it, plus desert dust and wildlife did it in.

      Barcoo Shire chief executive Mike Lollback said while the solar dishes never worked properly, they were “quite iconic” to the area.

      “By today’s standards, when you look at them you wonder what the devil they are,” Mr Lollback said.

      The solar farm was meant to provide Windorah with about 300,000 kilowatt hours of electricity a year.

      But 14 years later, the town of just over 100 people still relies entirely on diesel-powered generators.

      Windorah pub owner Marilyn Simpson said the solar dishes were a “big focal point” for curious tourists, but residents never saw any savings.

      “They like to pull up and view it,” Ms Simpson said.

      It was meant to save fuel, but it didn’t really save anyone’s power bill.

      Not surprisingly it was partly taxpayer funded:

      (From Wikipedia.)

      The total cost of the project was A$4.5 million with $1 million being provided by the federal government.

    Speaking of Boondoggles they tell me that Snowy 2.0 has slowed to a crawl, again and virtually doubled it’s potential cost. It’s still 10 years away from producing any power or at least more than it needs work. So here we are subsidizing solar panels that, on average, only produce electricity for about 30% of plated values. Wind mills limited to low – moderate wind speeds. Too little and they require diesel generation to maintain viability and too much they are turned off to minimise the chance that centrifugal force might self destruct and send the blades into orbit. The only thing that doesn’t stop are the subsidies and the cost power to consumers. We are the original crash test dummies.

    A post at Climate Etc by Planning Engineer also argues that solar and wind are not the efficient energy source they are purported to be” The main reason
    is their asynchronicity with the grid.

    ‘The green energy narrative is misleading in presenting intermittency as the major problem and implying that as we address this problem,
    wind and solar become comparable resources to more conventional generating resources. The green energy narrative hides the problems of asynchronous
    inverter-based generation when it can, and minimises the concerns around this technology when it can’t.”

    The Uniparty won’t stop until we revert to living in caves (or bark or stick lean-tos as per the previous inhabitants as we don’t have enough caves). Under the Liberal Party faction of the Uniparty (fake conservatives) the destruction may be slightly delayed.

    It’s (Solar Thermal) sometimes difficult to explain, really.

    The problem with Ivanpah is that basically, they wanted to see if it could work, so they used Units of 125MW and 133MW, and I’ll get to that in a second comment here.

    When it comes to Concentrating Solar Power (CSP) or as it is referred to, Solar Thermal Power, about the best they can manage is Units of 50MW.

    Now, all of that depends on the amount of steam (high pressure high temperature steam) that the solar part of the operation can ‘make’. The mirrors are focussed onto a central point, and the heat from those (concentrated on one point) mirrors is used to heat (up to a molten point) a ‘salt’ compound. Once molten, that (supposedly) now immense (loosely speaking) heat boils water to steam ….. the steam ‘drives’ the turbine, and the turbine ‘drives’ the generator. There has to be enough drive in the turbine to ‘turn over’ the weight of the rotor in the generator itself, and the bigger the generator output, (in MW) then the larger the weight of the Rotor on that generator. (See the point here) It all works backward from that rotor weight. bigger generator, bigger turbine, bigger steam (both pressure and temperature) bigger furnace, bigger heat source, and here that heat source has to be a constant heat, not cold (overnight) then slowly warming up, (morning) then reaching that point (midday into the afternoon) and then cooling again.

    As an example here, look at this image of a large coal fired Unit, just the one Unit here. (and for perspective, see the men standing around in the image) The 1350MW generator is in the foreground, with the green pipes. Behind that is the (really) immense multi stage turbine with the huge steam piping on top, feeding in that immense quantity of mega hot super high pressure steam. That size turbine is REQUIRED to actually be able to turn over the rotor inside that generator and then keep it rotating at a speed of 50 rotations ….. per second, so 3000RPM.

    It is all dependent upon that steam.

    Now, what has been found is that all the heat they can muster to make the best steam they can get to drive a turbine to turn over the generator and then keep it rotating, is to have a generator with a max power output of 50MW, so every CSP plant you see has Units with multiples of 50MW Units.

    Okay, back in 2008, when I started all this, it intrigued me, so I chased it all up. Numerous word structures in word searches etc and days and days of looking. Hidden away on around page 12 of one particular search was a huge 286 page ‘Paper’ on the future for CSP, (it’s referred to as ….. ‘Modelling’) commissioned by the US Department of Energy, and dated back in 1996, so now almost thirty years back. It was as dry as all get out, but it gave me an insight into CSP.

    Now as it got further into the modeling, the end resultant thinking was that feasibly, they could scale it up across the years with better improving technology. And, with confidence, the thinking was that they could end up with CSP being able to drive 660MW generators and have enough residual overnight heat to have the generator operational for 24 hours a day, all year round, and the prediction of the modeling was that all this was achievable by ….. 2012 at the earliest.

    Needless to say, they haven’t even got remotely close to this.

    More to come.

    So, Ivanpah believed that they (Ivanpah) had got THEIR modeling right, and that they could drive a 126MW and 133MW generator.

    Needless to say, they couldn’t, on the scale they actually thought possible.

    Now, (and this is something not really known by many people) most of these CSP plants, even those 50MW Units as well by the way, use Natural Gas (NG) fired technology every morning to, umm, ‘start up’ their Units for an hour, and usually more than that, while the solar process is heating up the compound to that molten stage where it can make the steam required, and then that cuts in and the NG cuts out.

    Now, once Ivanpah was up and running, they found the problem that they couldn’t get enough steam from the solar process as early as they expected, so the NG portion of the plant was operational more than expected. So much so in fact that the plant itself ran into the problem that it was in danger of now being classified as a NG fired power plant. In 2015 in fact there was the thinking that because of this excess NG consumption, then this ‘Renewable’ power plant was in danger of becoming subject to the Cap and Trade tax, and, umm, that might have just proved a tad embarrassing even.

    Okay, so blah blah blah, the plant operated, delivering its power since 2014, so ten years of operation.

    Most of you wouldn’t remember, but these plants were touted to be the future of renewable power, the great saviour in fact, the ACTUAL future replacement for coal fired power.

    It was originally expected that this Ivanpah plant could deliver its power at a Capacity Factor of 30%. (and shh! don’t tell anyone that this figure is supposedly fantastically fabulously incredibly good, being as high as that)

    It never reached that figure, and is currently delivering at around 20%, not much better than solar panel power plants, and in fact at a lower CF than wind power even.

    Back in 2013, when the hype was at its highest for CSP, I did some research on these CSP plants, and I honed in on Spain, where they were building them at a large scale. At that time, they had 24 of these CSP plants, so I ‘did the maths’, and made this Post with a chart listing each plant, comparisons, the whole deal, and again, the overall CF was below 30%, and this was not for just one isolated plant, but for the whole ‘fleet’ of them in Spain at that time. At that Post of mine, there’s also an image and text explaining the process as well.

    So, you’ll hear all sorts of stories on why Ivanpah closed down.

    But basically, it’s just a failure stemming from ….. Physics really!

      A while back now, I, umm, rationalised my collection of bookmarks, and sometimes it’s like which ones to keep. I got rid of around 300 plus, and now I only have around 200 or so, and since then, I’ve added 70 or so recipes, now I’m ‘into’ cooking.

      One of the ones I got rid of, and perhaps inadvertently was the reference I used for those Spanish CSP power plants.

      Luckily, at the bottom of that Post, I actually included that link I used for those solar plants.

      Here, if you click on any of the plants and look closely in the ‘Description’ box of data, you’ll see that most of these CSP plants use Natural Gas for Startup and Backup.

      On the menu bar at the top, you can also ‘chase down’ and power plant you want to as well, so I’m glad I have this link back. (Phew!)

        One of the ones I got rid of, and perhaps inadvertently was the reference I used for those Spanish CSP power plants.

        I used to teach about one of the Spanish (Acciona) parabolic trough systems in Nevada. If I remember it’s rated at about 70MW. One wonders whether drill baby drill is going to rule a red line through this and other heliostat and trough systems. After all, cap. factor is a concern for all solar systems, no matter how fancy the design.

        Thanks Tony.
        I wonder what the physics and engineering folks were doing when these CSP facilities were first proposed.

    For Australia it’s critical that we stop building any more toxic ,unreliable W & S disasters and only build safe, reliable base-load energy like Gas, Coal or Nuclear.
    IOW if it isn’t base-load energy we should forget about it, because the W & S CFs are a joke and will make our future very uncertain if we have to defend ourselves against China, Russia, Iran, Nth Korea etc.
    I think everyone who has the time should watch Alex Epstein’s latest video and he makes this most important statement at the beginning and the data supports him…… “Fossil fuels didn’t take a safe climate and make it dangerous, instead fossil fuels started with a dangerous climate and made it safe”.
    Today we have 8.1 billion people at risk and yet we also live in the safest period in Human history.
    OWI Data shows this to be true and the honest Scientists compare the 1920s deaths to 2024 and extreme weather deaths have dropped by 98% over the last 100 years.
    Under 2 billion people in 1920 and over 8.1 billion today and yet the death toll is only one fiftieth today. And Dr Koonin always wins his debates easily when he quotes the honest data.
    Here’s Alex Epstein’s latest video and his important statement is at the beginning.

    One of the problems for early Concentrated Solar Power (CSP) electricity generators like Ivanpah has been no electricity generation between sundown and sunup and also intermittant electricity output on claudy days. Just like with solar panels. Also, with China flooding the market with cheap panels, energy generation by CSP at Ivanpah became unprofitable.
    However one advantage of newer CSP electricity generators, like the 110MW Crescent Dunes power plant in Tonopah, Nevada, is the successful use of heat storage by various means that allows electricity to be generated after dark. Unlike solar panel electricity generators which use huge banks of potentially dangerous Li batteries to run electricity to the grid for a few hours after sundown, the latest CSP generators use either water or sand to store energy for use in efficient heat exchangers to keep generating electricity after sundown. Molton salt is also being trialled.

    For 1.6 Billion dollars, I’m truly shocked. They told us all that solar energy was cheap. / sarc

    Anything that isn’t market driven, ought be funded by the salaries and pensions of the companies and pollies that advocate them.

    Or, their salaries and pensions ought be inversely paid according to residential electricity costs, with a reference base of $30/Mwh.
