World's Largest Solar Plants Planned In California

Posted by Soulskill on Sun Aug 17, 2008 12:30 PM
from the go-for-the-gusto dept.
Pickens writes "Two photovoltaic solar power plants will be built in San Luis Obispo County in California, covering 12.5 square miles, that together will generate about 800 megawatts of power, the latest indication that solar energy is starting to achieve significant scale. 'If you're going to make a difference, you've got to do it big,' said Randy Goldstein, the chief executive of OptiSolar. OptiSolar will employ enough of its amorphous silicon thin-film solar panels at its Topaz Solar Farm project to generate 550 MW. Meanwhile, SunPower will install mechanical tracking for its more expensive 250 MW-worth of crystalline silicon photovoltaics at High Plains Ranch II in a bid to boost their efficiency by 30 percent from following the sun across the sky. The power will be sold to Pacific Gas & Electric, which is under a state mandate to get 20 percent of its electricity from renewable sources by 2010. The utility said that it expected the new plants to be competitive with other renewable energy sources, including wind turbines and solar thermal plants. 'These landmark agreements signal the arrival of utility-scale PV solar power that may be cost-competitive with solar thermal and wind energy,' said Jack Keenan, chief operating officer and senior vice president for PG&E." Reader thefickler notes some related news that researchers have developed a method of collecting infrared rays at night to supplement day-time solar power.

      Yes, mod parent -1, because talking common sense when talking about environmental and social concerns is practically sacrilege. Why -1? Because he isnt in your environmentalist hippie nuclear power hating cult? Give me a fucking break. If nuclear power produces that much more power, in a more confined area, for less money, and produces negligible amounts of pollution whats the problem?

      I would love to see solar and wind to become the only needed power source, but that isnt a reality. While this article shows that solar is an improving technology, it is also showing that we have a long way to go for a real alternative to our current reliance on the only real options available: continued use of fossil fuels or nuclear. Reducing consumption is argument non grata. For example: Your still waisting electricity to post on slashdot.

While solar might be particularly well suited to covering energy needs when air conditioners kick in during the summer, what happens when we plug in our electric cars at night, or rely on electric heat when natural gas and propane prices go even higher?

        Perhaps we can use the limited information over power to load balance car charging during night hours, but even then we will either need nukes/coal, or invest in some highly expensive solar storage solut

        Why does this drivel keep getting posted and moderated up? I'd give a -1 myself but I think it's better to post and try to make a point. I haven't seen anyone saying that we are going to completely get rid of fossil fuels. I haven't seen anyone saying that we are going to go to 100% renewable resources. Those seem to be the strawmen that are always trotted out in these discussions.

        The point in renewable technologies is that any additional power that we can get outside of the fossil/nuclear fuel box is a good thing. The power demands of society will continue to increase. I'm not completely convinced that petroleum (note I don't use the term "fossil fuels") is a limited resource. However it is quite possible that we will continue to consume it more quickly than it is replenished by whatever process pumps the stuff into the earth's crust. Nuclear (uranium and plutonium) energy sources are scarce and hard to get to. One of the big reasons we're in Afghanistan is because they have huge uranium deposits there. I'm getting off on a tangent so I will try to draw a couple of analogies here.

        Just because you might never win the Boston marathon doesn't mean that you shouldn't do cardio training to keep yourself healthy. Just because you will never be a body builder doesn't mean you shouldn't exercise and have a good diet. Just because you can't afford a Ferrari doesn't mean you shouldn't drive. Just because wind and solar power might not ever produce base load power doesn't mean that we shouldn't harness them to the best of our ability. Just because one particular technology might be "better" than another does not make the other technology worthless. To use a computer analogy... "Why do you even bother with a stupid desktop computer? Obviously a supercomputer is much more powerful."

              Nature doesn't keep secrets. You can't uninvent anything, ever. You just have to learn to mitigate and live with it.

              The basic principles behind a nuclear weapon and nuclear power are the same, but having a nuclear reactor won't get you much closer to a nuclear weapon all by itself. The bombs themselves are dead-easy. Really all you need to do is quickly bring two sub-critical lumps of weapons-grade fissile material together and BOOM.

              Getting the fissile material and enriching (essentially, concentrating it down) it is the tricky part that takes government-level resources to accomplish. Fuel for a nuclear power plant and its wastes are useless for making a bomb without the critical enrichment step.

              That being said, there are some very real concerns over existing nuclear power plants. No private company will insure them, the high risk and long payback period on the initial investment scares away most investors, and they can't be shut down and spun back up as needed for fluctuating power demands, so they're not suitable for everywhere. Blindly declaring "build more nukes!" isn't going to be very helpful. We need to give careful consideration to if, how and where we build more; and focus on promising new designs that mitigate many of the drawbacks (pebble bed, breeders, thorium, etc.)

                Ok, if you say so. However, just a few catches.

                How large lumps?
                What shapes should they be?
                How pure do they need to be?
                How quickly do you need to bring them together?
                How long will they have to stay together?
                How powerful will the explosion be?
                How powerful explosives do you need to bring them together quick enough?
                Will you need a neutron source to ensure the chain reaction begins at the right moment?
                If so, how will you build it? Will you use Polonium-Beryllium or D-T fusion?
                How do you ensure the neutron source triggers at the right time?
                When should the chain reaction start to ensure a powerful yield?
                How many neutrons does your neutron source produce?
                Does it produce the same number of neutrons every time?
                Is the fissile material you use pure enough for a gun triggered design (hint, plutonium will not be)?
                If not, how do you build an implosion type weapon?
                What explosives can you use for the explosive lenses?
                What shape should the lenses have?
                What is the detonational velocity of the explosives you use?

                Otherwise I agree with you. Once you have worked out those tiny details there, and a couple of others like them, you just need to bring two pieces together. Of course, this all assumes you have the fissile material to begin with. Weapons grade Uranium is not exactly easy to manufacture, and getting Plutonium-239 pure enough from Pu-240 that you can use a simple "bring the pieces together" design is extremely challenging.

          I believe that this is the first time I've heard of 'wave away' being used to disparage recycling. With recycling the waste is split 90/10 into usable fuel and waste that only needs to be stored for a couple hundred years - much more doable.

          This is another example of the environmentalist's fallacy.

          First, why focus on nuclear waste while ignoring all kinds of other long-lived, harmful industrial outputs from processes like semiconductor manufacturing or steel refining?

          Second, the volume of nuclear waste is tiny [world-nuclear.org]. The waste produced by a nuclear plant in a decade might fill a house. And by reprocessing the waste, we can reduce its volume by 90%. Compared to other forms of power generation, nuclear plants are practically clean.

          Third, the waste that is produced is not all that dangerous: the way radioisotopes work, the more radiation a substance produces, the shorter its half-life. Long-lived waste products will be low-radioactivity and inert.

              Plutonium is not very radioactive. Its activity is fairly low. The half life of Plutonium 239 is approximately 24,100 years, meaning that any given atom probably lasts a very long time before decaying. In turn this means that the number of atoms decaying at any given moment is quite small. Furthermore, Plutonium decays in the form of alpha particles, which don't penetrate at all. Alpha particles are stopped by human skin, still in the dead bits, and thus are completely harmless when external to the human body. You can hold a big lump of Plutonium in your hand all day and not have the slightest ill effect. It only becomes dangerous when ingested, and even then it tends not to be absorbed by the body except in certain forms, for example fine particles breathed into the lungs.

              As for toxicity, it's pretty bad, but not nearly as evil as it's made out to be. I'd certainly rather have a little more Plutonium around than live with the many tons of mercury per year emitted straight into the atmosphere by the average coal plant, given the choice between the two.

              Lastly, consider that several tons of Plutonium have been released straight into the atmosphere as a result of nuclear bomb testing, and there hasn't been any real environmental harm from this. It's certainly no good thing, but on the other hand this is vastly worse than what happens with nuclear waste, which is safely stored rather than being vaporized and released into the air.

      There are simply only few places where a power plant can be built at all, even if no humans lived everywhere and had something against it.

      In the summer last year multiple nuclear plants in Europe had to get special permissions to make the rivers boil or they had switched off, just because there was not enough cool enough water in the rivers. So limiting a nuclear power plant to the area is takes itself it just absurd, you need much more place.

            I see your point. But we can mitigate the problem:

            According to wikipedia [wikipedia.org], we can build turbines that reach 90% efficiency. That leaves us with 100MW of power to dissipate (not a 1GW "hair-dryer").

            First of all, the output of that turbine is going to be barely warmer than the surrounding air. (Think about it: if it weren't, you could use it as the input to another turbine stage.)

            Sure, there will be a lot of this output, but it won't be particularly hot. Also, I imagine you'd use a condensing turbine, so you get most of your original cooling fluid back. What's left is a large volume of warm, dry air. Lots of industrial processes produce that kind of output today, and we don't see birds dropping out of the sky.

        Again, reprocessing vastly increases the power obtainable from a given amount of uranium, and use of breeders also means that we can use lots of other radioactive elements, many of which are far more common than uranium.

        The power plant that you can see four miles from your house is just a tiny part of the whole complex.

        A fact that is even more true of PV solar plants.

        Fission is the cheapest, cleanest energy technology we have, and one of the safest as well. Unfortunately, it's bound up in nearly-intractable political problems. Eventually, though, oil and coal will be expensive enough, and we'll have seen that solar, wind, wave, etc. technologies simply aren't workable on a sufficiently large scale, and then the political obstacles will disappear.

    So, what would it cost to replace California's carbon point sources with 'renewable' (I know it costs energy to make these things) energy? I'll share my math, others can expand:

    It says here [ca.gov] that California in 2007 used 230,931 of 'non-renewable' energy. It says here [ca.gov] that California's peak demand was 52,863 MW when total usage was 265,000 GWH (2002). Adjusting to the current levels, a 14% increase, we get a current peak of 60,264 MW.

    So, if these solar plants can produce a combined 800MW, you'd need 75 of these projects to handle peak energy generation. If we factor in 10% for transmission losses, and another 14% increase over the next six years (while they get built) then you're looking at 94 of these projects, which is really two projects, so 188 plants, or by 2020, 214 plants, using 1,338 square miles of desert. That's only 5% [desertusa.com] of the Mojave Desert, ignoring mountains, ignoring environmentalist lawsuits preventing destruction of desert habitat, not thinking about what happens when Joshua trees want to grow up under solar panels (Monsanto Roundup?).

    So, that's 18 plants a year to build. It's probably possible, though what that would cost in rare earth elements, and what would the construction of such project do to the market prices of those rare elements? I don't know, except to think it would be bad.

    OK, so how about replacing natural gas, outside of electricity generation? Using the information from here [ca.gov] it says that half of the natural gas is consumed for electricity generation, so we can double that part of the number for the total energy budget of electricity and natural gas. That increases the GWH total to 298,962 GWH, or a 29% increase. So, we're up to 276 solar projects.

    So, how about converting all the motor vehicles to plug-ins? It says here [ca.gov] that CA uses about 24 Billion gallons of transportation fuels a year. This calculator puts that at 3,032,000,000 GW, or if divided by the number of hours in the year, gives 345,881 GWH (TODO: check units?). So, add to our current total and multiply by 2.16 and get 596 solar projects, at 3725 square miles, or about 15% of the Mojave Desert, and 50 of these solar projects a year to get CA largely carbon-neutral by 2020.

    Now, this is a bit of a simplification. This is meeting peak demand with current generation. There might be some opportunity for storage, though demand somewhat parallels light availability. What is the quoted efficiency, average (during what time period) or max? This doesn't count wind power as I don't know the rules of thumb for standby generation (I heard recently 90% standby needed to be in production for wind to account for variability and startup time). I'm assuming no new hydro will be built (probably safe). I'm assuming solar won't get more efficient (it will). I'm assuming the installed solar won't lose efficiency over time (it will). I don't know what the proper rule of thumb is for calculating demand based on time-of-day usage. etc. So, it's much complicated, but I wanted to understand what scope people were talking about when they advocate an all-solar solution.

    I'm also counting nuclear as 'non-renewable' in this calculation as folks who want all-solar usually are anti-nuclear. If you factor in the existing nuclear generation it gets a bit better. If you wanted to power CA on all-nuclear instead you'd need about 300 reactors covering 22 square miles of land, if they're like the 1.6GW one they proposed in Fresno. Or you could use newer, safer technologies instead and clean up our existing nuclear waste by feeding stuff currently bound for Yucca Mountain into these reactors and

      Indeed. I'm convinced that if big solar plants are ever going to be worth building, they'll have to be based on a thermal approach rather than PV technology.

      The molten salt system looks quite promising from the standpoint of solving the time of generation/time of use problem.

      • Whatever technology they use it'll be out of date before they finish installing 12.5 square miles of the stuff, and replacing it will mean starting from zero.

        Compare this with thermal plants (mirrors focused on something to heat it up). The mirrors and focusing system remains the same, you just change the central element.

        Thermal plants are far more sensible at the moment. This plan is yet another example of environmentalism gone mad.

        12.5 square miles of silicon, and it still generates less than a single average sized block of a nuclear power plant (~1000 MW).

        is that counting all the space taken for the railways to bring in and store the coal? (or for the mine for the coal)

        Me: Since when does Nuclear or Solar require Coal?

        • Make the market efficient enough that the trillion or so spent on the Iraq war comes out of the oil company pockets, instead of adding to them, and I'll agree with you.

          When the industry/consumer actually pays _all_ the costs associated with the technology, then we can do away with taxes that favor one approach over another. Until then, I'm all for taxing polluting & non-renewable industries and giving tax-breaks to non-polluting & renewables.

              My point is that government regulation and intervention is often a good thing. Let's look at energy specifically. Coal is cheap if you ignore its huge, disastrous externalities. In an unregulated market, we'd all be using coal. Now, we can ban coal outright, but that's very disruptive. A far better idea to simply make it expensive (or equivalently, make its competitors cheaper).

              In this way, government tax manipulation makes markets work better.
