Texas Just Got a New 1.1-Million-Panel Solar Farm (electrek.co) 93

An anonymous reader shared this report from Electrek: Renewable developer Clearway Energy Group has completed a 452-megawatt (MW) solar farm in West Texas — and it's huge... It's built on around 5,000 acres of land and features over 1.1 million solar panels... Texas Solar Nova will generate enough electricity to power over 190,000 homes annually.

It's got an offtake agreement with telecoms giant Verizon, and agreements with auto component maker Toyota Boshoku and Swedish bearing and seal maker SKF to purchase renewable energy certificates (RECs). Both Toyota Boshoku and SKF have 12-year agreements for RECs.

The $660 million facility will "contribute significantly to the local tax base," the company said in a statement, "starting with an estimated $5.4 million in property taxes and wages to be paid in the first year."

    Average house power considered 2378 W (452/19000), average power of the farm 22.3 W/m^2 (452/5000), each powered home uses 106.5 m^2 of the solar farm land (5000/190000).

    • 2.6% of an acre of farmland wasted per house. That's actually seems OK to me.

      • The solar farm only takes up about 0.003% of the land in Texas. I think they can manage that.

        Average suburbs home density is around ~50 by acres. It's much more in the city. So say solar farm takes the space of 250,000 suburbs homes to serve 190,000 homes in electricity. Not bad I guess for a place like Texas but some countries just don't have the space available for this to scale everywhere IMHO. Anyway, it would more than double the area taken by housing needs globally.

          But housing needs take up only a small fraction of land use, so that's not really a big deal.

        Texas has a lot of desert and other essentially uninhabitable land, it's a great place to put solar panels. They reradiate most of their heat into space, so they actually will help cool Texas if enough of them are installed.

        You ever been to west Texas? Unless you irrigate the heck out of it, it's not really "farmland".

        Cattle range, maybe.

    • I don't think storage is essential in Texas yet (utilities offer "free nights" plans), but with the company selling the RECs that covers about half the costs, so they would be less dependant on time shifting. If/when it does make sense I am sure they can add it.

        There is a federal statue in place that specifies that all communications published in the USA which discuss any energy or power-related topic MUST include an inappropriate division by some factor of time, such as "KW per day".

      Of course they have energy storage. I suspect people would see plenty of energy storage in Texas if they only know what to look for. Look for large steel tanks full of natural gas.

      The natural gas industry loves to see more wind and solar power project pop up since that means more customers for them. Big steam power like coal or nuclear fission (and in some cases thermal solar) can't follow load well so to make up for the relative rapid gain and loss of solar power every day there must be a reserve of natural gas fuel and power plants to burn that fuel.

      With big steam power there's something of a reverse problem to that of solar and wind but the solution is much the same, natural gas. With big steam not liking to ramp up and down rapidly with changing demand there much be some part of electricity production that is natural gas. Reciprocating engines burning diesel fuel can also work for something that can ramp up power output quickly, and back down again as load disappears, but typically natural gas burned in turbines is much cheaper.

      Solar power is not a threat to natural gas. What might be a threat to natural gas is some form of inexpensive electrical storage but even that is half the battle. With storage there is still a need for production and natural gas produces power as well as provides a convenient storage method, it's a kind of "two for one" deal that solar and batteries are not likely to ever compete with since steel tanks are going to always be cheaper than batteries for energy storage.

      Solar power has a capacity factor of somewhere between 25% and 30%. The sun might shine an average of 12 hours per day through the year but the intensity is going to be less in the mornings and evenings, that's why we aren't going to see 50% capacity factor from solar PV. When averaged over the year a 450 MW solar PV system will produce about as much energy as a 150 MW coal or nuclear power plant with 90% capacity factor. Coal power plants rarely get 90% capacity factors any more, not because they can't do it but because it's often cheaper to burn natural gas instead.

      Solar power has been a proxy for natural gas for a very long time. As more solar power is added to the grid then more natural gas production is added to the grid. Just ask Germany how adding more solar power to the grid has worked out for them.

      • There is a factor which gives solar storage a huge advantage over natural gas, natural gas storage costs a lot of money to produce the fuel you are storing. By contrast the marginal cost of producing fuel to store with solar is close to zero. Of course energy conservation is cheaper than either, which is why we have but abandoned energy conservation as a strategy. There is no money to be made, at least not on an investor friendly scale.

        Of course they have energy storage.

        Some form of storage is a given these days. It can double the profit of the farm.

        OTOH this is Texas, so... maybe they sell the midday excess to Bitcoin miners instead of doing something useful with it

      • I suppose... but then there's this...

        https://www.reuters.com/busine... [reuters.com]

        • Yeah. One of the side effects of solar has been to shut down base load generation and add gas turbines to handle peak loads. This has made natural gas generated electricity much more expensive because the capital expenses have to be amortized over fewer MWh.
    • Not likely. What they do with these solar plants is oversize them, or under max them. If it can produce 100MW at full power, they only rate the plant at 70-80MW. That way they can be at 'full power' over a longer period of the day no matter the weather or season. This is important for grid stability. (in TX....haha)

      And yes you could say the 'extra' is currently wasted. But since there's zero fuel spent, it's effectively zero operational cost. But it's also a future source of additional capacity on
      • The extra unused capacity isn't free. There was capex, the cost of the loan or bond or whatever was used to build it, and a larger facility requires more maintenance, which is opex.

        I'm in favor of over building infrastructure but let's not fudge the math on it. That's how everything turns into an unexpected cost over run and budgets get fucked and so on and makes the next project harder to fund.

        • 'effectively'. There's no fuel cost to it.

          And it's literally planned. The cost of building 120% of planned power output is the cost of being able to provide 100% over longer periods and less than perfect sun. It's smoothing out the variable output of solar. The extra power you curtail at noon without storage is part of the system and is costing 'effectively' nothing. It's part of the design.

          Cost overruns aren't at all the same thing.
          • That's all good, I'm with you except it's not 'free' or even effectively free. The cost is built in as you say which makes the cost per kWh go up.

            • Citation needed.

              The 'cost' of oversizing isn't compared to not building it. It's compared to having to provide the extra power a 100% sized system can't provide.

              And that extra power is costing actual fuel per kwh, not a fixed cost of infrastructure (and yes that fixed includes loan amortization rates, since those do not cost 'per kwh').

      • by AmiMoJo ( 196126 )

        Another option is to just use the excess power when it is available. If you can find industrial processes that you can run intermittently, with a day or less notice of cheap excess power availability, you can just consume that energy.

        • That would certainly be ideal. Unfortunately from grid mgmt it's not really viable. Coordinating various industrial plants temp processes with the weather and cloudy days isn't an easy endeavor.

          That's precisely why they oversize the installs, to smooth out that variability.

          Local battery storage or hydrogen solves that coordination issue.
        • Or design processes to operate with some flexibility or seasonality. Like maybe desalination in California. Or synthesizing hydrocarbons using solar for those applications which can't be electrified.
    • It looks from the summary that they already have contracts with large scale consumers that will pull every joule they can crank out even during peak output. Maybe they can add storage later if those contracts expire or if the grid in Texas for some reason loses their backup natgas capacity.

      • The Texas grid collapse? Gasp! That could never happen!

        That was one of the major reasons I skipped Texas when looking for a new place. They don't know how to run a state. Coming from California it would just have been frying pan to fire.

        • I'm not talking about a grid collapse. In that event, no manner of battery storage would help. I was more thinking that if political forces conspire to strangle the natural gas industry in the United States, making it effectively impossible to generate power with it.

    • But surely, they must have also built some storage to go along with that, right?

      No need. Texas can just build more crypto farms to stabilize the grid. /s

      Almost certainly, yes. I say this from first-hand knowledge, working for a utility in Texas. The last several solar farms we've connected into our transmission system in the last five years (which has been quite a few, as solar farms of all sizes are booming across Texas) have all included a BESS [wikipedia.org] (Battery Energy Storage System) component as part of their design.

      Now, these are not long-term storage systems. On average they provide approximately two hours, though up to five hours is not uncommon. They're meant more to keep the output of the farm stable and consistent since things like cloud cover can significantly affect power production.

      As for long-term storage, there are some pure-battery storage farms in operation in Texas. One called KCE TX 11 comes to mind off-hand. It's a 50 MW facility. There are others as well, and more being planned.

      • 5 hours is WAY better than nothing.
        • by shilly ( 142940 )

          I saw some work a little while ago that suggested that the addition of just a modest amount of storage can drive up reliability dramatically -- to something like the low 90s%. And that overcapacity can take it to the high 90s, which should be ever more attractive as a strategy as solar and wind costs fall. With the free bonus of increasing amounts of cheap power that we can do funky things with at some times of the day / month / year

    • They might not need storage. It seems wind power lags during the day, when solar is at its best. So the two tend to roughly even out. There are some graphs here that help visualize how wind and solar complement each other.

    • by AmiMoJo ( 196126 )

      Many solar farms have small batteries to smooth the output.

      Another technique is to build vertical panels, which help cover the times early in the morning and late in the evening, when the sun is low in the sky.

      Solar is so cheap now that it's become viable to have double sided panels, to pick up reflected light too.

  • Finally they may have a backup power source next time their crappy jury-rigged power grid fails due to their conservative politicians constantly working to uninvent electricity!

Their attorney general is famously on video saying that he personally prevented the Democrats from taking the state with the implication being that voter suppression is what made it possible. He's under multiple investigations for a corruption and eventually he'll come down. If the Democrats can take that and maybe the Secretary of State then they'll be able to have Fair elections and in all likelihood the state will flip blue and they'll get some federal money for the upgrades and changes they need and connect to the grid like everybody else..
    • Japan is about half the size of Texas and manages to run their own independent power grid. Of course Japan's GDP and population is much larger. And Texas's GDP is roughly similar to Brazil's but the population is about an eight. Japan, Brazil, and Texas are quite capable of running an electrical grid.

        Japan has 2 mostly separate grids, one running at 50Hz and one running at 60Hz, with not much interconnectivity.

You can exchange electricity between different synchronous grids, regardless of frequency when you use modern HVDC interconnectors. Japan doesn't do this much, but the technology is there and it is used quite a bit in the US.

      On the conservative sites I troll they are perfectly aware solar works when the sun is up and not when it's down, but so not specifically hate it. They just want power 24 hours a day, not only when it's sunny.

      Solar provides independence. You can have an on-grid setup and reverse meter, or have an off-grid or hybrid system and keep a battery bank charged. I've known people who threw panels on a roof of their house and carport, enough to keep a battery bank going that provided power
