Florida Utility To Close Two Natural Gas Plants, Build World's Largest Solar Battery System (electrek.co) 102

An anonymous reader quotes a report from Electrek: Florida Power & Light has joined the race to build the world's largest solar battery storage system, announcing plans for its massive Manatee Energy Storage Center. The utility plans to build a 409 MW/900 MWh battery, to be powered by an existing FPL solar plant in Manatee County, Florida. It will begin serving customers in 2021. FPL says the battery system will be able to power 329,000 homes for two hours. For comparison, FPL notes the battery system is equivalent to 100 million iPhone batteries, or 300 million AA batteries. The system will be used in periods of high demand. The utility company also said that it will accelerate the retirement of two natural gas facilities at a nearby power plant. "FPL says the project will save customers more than $100 million while eliminating more than 1 million tons of carbon emissions, though no cost estimates for the project were disclosed," reports Electrek.

And while the Manatee Energy Storage Center is projected to be the "world's largest solar-powered battery storage system," it will have some competition from Texas where there are plans to build a 495 MW battery storage system that would be paired with an equivalent 495 MW solar farm in Borden County, Texas. It too is due to come online in 2021.

  • They build it in Texas, they close fossil fuel plants so you can bet your ass that money can be made this way.

    • ...they're NOT closing anything in relation to this announcement. In fact, had someone clicked on the article they wouldn't have to scan too far to find this:

      "Texas’s power grid operator has stressed the need for more electricity resources in the region to power oil and gas drilling operations."

      So no, they're not closing fossil fuel plants in favor of this...and the reason they're building this is BECAUSE of fossil fuel efforts.

          Not an admission by the Texas grid operator, they've been big on wind for awhile. The problem is that the pols are big on wind too, but only when it issues from their mouths.

          How the grid owner can profit most with solar and batteries. It sells those systems, supplied and installed, first profit, it handles and sells the electricity coming off those systems for profit. For those who can not afford to buy outright, it leases those systems and the energy they sell, helps pay for them over time. As the grid operator it will have a monopoly of the buy price and sell price of that electricity and will not have to negotiate with a major energy corporation, so the margins will be big.

          • Going forward, for sound investment reasons, you have to separate grid owner and operators from power station owner and operators.

            I agree. All electricity generation should be nationalized.

        This is a good demonstration of something few people realize: oil, outside of the conventional reserves in the middle east and a few other places, isn't really a viable energy source. American shale oil extraction is energy positive, but not enough to be really worthwhile. Oil's value is mostly as an energy storage mechanism to power transportation.

        So it doesn't make sense to burn that oil to power your extraction operations. It does make sense to build a solar facility to power extraction.

          Your assertions seem plausible, but do you have some cites to support what you said?
          • by ceoyoyo ( 59147 )

            Try starting here: https://www.sciencedirect.com/... [sciencedirect.com]

            Energy return on energy invested is the basic idea: how many barrels of oil do you get if you invest one barrel of oil in production? Shale oil and tar sands are quite a bit below the world average, which means middle east conventional oil must be considerably above that average.

            Now, this is my speculation, but a bit of math with fuel prices would probably support it. Oil is a famously inelastic resource, meaning it doesn't really obey the law of supply an

    • >"They build it in Texas, they close fossil fuel plants so you can bet your ass that money can be made this way."

      Hopefully, yes. Trying to force something to work that isn't ready doesn't pan out well for anyone. This could mean the technology is finally ready. That is good, because we need reliable, long-term energy independence.

  • So..... Floridans have finally figured out that they can use the sun to run the air conditioning systems they use to escape the heat of the sun?

      What if a combination of a reflective roof, improved sealing and insulation of attic ducts, and a higher-efficiency A/C unit is more cost effective than a solar photovoltaic panel?

      The reflective roof is more than covering your house in tin -- there are coatings that reflect sunlight with better combined ability to reflect incoming radiation along with emit heat that gets in as infrared. Florida houses typically lack basements, so the A/C ductwork is in the hot attic -- sealing air leaks and insulating the ducts helps a lot. Newer A/C units are much more efficient.

      "Uh, why not do both solar electric and A/C efficiency?" Indeed, why not, but all of the resources and press attention is going into the production side over the demand side. Low-hanging fruit, baby!

      • Indeed. What's the point of adding all these new "green energy" systems everywhere if you're going to keep wasting most of it?

        "What if a combination of a reflective roof, improved sealing and insulation of attic ducts, and a higher-efficiency A/C unit is more cost effective than a solar photovoltaic panel?"

        Then do that too.

        I think you're missing the point that this is not a rooftop system. That's important. For argument's sake, let's say this system is 1GW peak. To deploy that on homes you'd need to install 200,000 average 5k rooftop systems. Or, as you suggest, you could improve existing systems to lower the energy use. If that's 1kW per home, then you need 1,000,000 homes to be upgraded.

        Current pricing on utility-scale solar is about 80 cents/W. So installing one 1 GW plant will cost you about 800 million dollars. In contrast, installing on the rooftop costs about $3.25/W, so that option would be 3.25 billion dollars. Re-doing the homes as you suggest will cost thousands per home, so I would not be surprised if it was tens of billions.

        So the end result is the same, 1GW offset. One solution costs many times less than the others. Done like dinner.

      • all of the resources and press attention is going into the production side over the demand side.

        American demand for electricity is declining, and is 4% below the peak.

        LED lights, better insulation, more efficient appliances, are all driving the decline.

        This doesn't make the news because it isn't flashy like a big new solar battery installation.

        The adoption of electric cars may reverse the decline.

        • Peak electricity demand during the 24 hours of a day will still decline when electric cars are widely deployed. Electric car owners will be incentivised to use cheaper off-peak electricity tariffs during the night. Therefore, the minimum electricity demand will increase during the night to charge up electric cars. This will benefit the Nuclear industry and wind industry by allowing the baseload limit to be increased to accommodate electric cars. It is likely that the number of power plants will go down desp

      Geez .. don't you know .. the manatees are going to be the operators of the plant! Thats why it is called a Manatee Energy Storage Center - the Manatees are operating it.

      This is really forward thinking by Florida. When climate change floods the whole state and everything is underwater you'll find that the manatees are eminently suited for manual labor. So its essential to start getting them trained up now for the job.

    First of all, is it true there's only the equivalent of three AA batteries in an iPhone?

    Secondly, 100 million iPhone batteries or 300 million AA batteries may sound like a lot, but when divided by the power required by houses, it doesn't seem like much. Can someone convert that in a how-many-tesla-car-batteries-can-fit-in-a-stadium number?

    We used to call Florida Power and Light (FPL) "Florida Flicker and Flash" when I lived in the Orlando area. They had terrible power. Blackouts weren't that bad, though not rare. But constant brownouts, momentary flickers, occasional spikes were daily life. They couldn't control it worth a damn. Then they brought plants like those two natural gas plants online and things got much better. Guess that was too good, so they want to go back to the flickering and flashing...

    • Frequency control is a big part of stable power and batteries are very good at instantaneous adjustments. Better and more efficient than gas. People have it kind of wrong when they think of batteries powering 100s of 1000s of homes for a number of hours, it will never be used loke that. Instead when systems detect a short term drop in power generation they use the batteries for a few minutes to stop it cascading into something worse. That's what stops brownouts and flickering power.
  • Will tripple or even quadrupole. So far all this "alternative energy" stuff on a large scale has shown not to be less expensive but more expensive. If they really want to sell solar or wind as a better alternative - they need to make it cheaper in cost. It's still cheaper to use natural gas, coal or fossil fuels. I bought solar panels to put on my property to take advantage of the "free" sun. But wow was it costly. It will take me 20 years to recoup the cost......

    • If you can recover the costs within its lifetime compared to using fossil electricity, it's not more expensive, it's cheaper.

    In CA PG&L is closing three natural gas plants replacing them with batteries. Four systems, two experimental at 10 GWh each. Two large systems 350 MW x 4 hours and 175 MW x 4 hours.

    South Australian grid using wind mills widely separated was the first one to go in with a 50 MW system. It stabilized the grid and flattened the spot market prices so much they saved millions of dollars. Every dollar saved by the utility is a dollar NOT EARNED by gas powered plants. The ROI on natural gas plants are going to take a serious rework, they are losing juicy profits in the spot markets.

    Now, Florida. Cost of storage batteries [twitter.com] is falling so rapidly, it is like the micro chip revolution in computing. There is a Moore's Law for batteries, with a time period of about 7 years.

    The neck of the famous "duck curve" [wikipedia.org] is after sunset in CA. Solar has stopped, but a/c load is yet to peak. That one hour after sunset is the last critical piece needed for solar to become totally effective against natural gas. It is at hand. It is very exciting for the renewable energy fans.

    Some of the gas plants operating in the peak load are "quick response" gas turbine plants. Their quick response is still measured in tens of minutes. The batteries are responding in milliseconds. The key thing about spot market electricity is, the price can go negative. If the gas plant is producing power and the grid could not absorb it they need to pay someone to take their power. The gas plant will not throttle down for several minutes. Who can absorb that power and get paid? The Batteries! Once the battery systems reach a critical mass, all natural gas fired power will be sold at long term pre negotiated fixed contract prices. Not the spot market. This will seriously change the ROI calculations of these plants that were already built. I am expecting the owners of these plants to cry uncle and come with hat in hand asking for "relief" from the utility rate payers.

      Which is pretty much what FL is doing. Note that what is closing is NOT coal plants. They're replacing one (relatively) clean system with another (cleaner) system, NOT replacing a dirty system with a clean one....

      Which, interestingly, is something I saw predicted a few months ago - that solar isn't going to be replacing coal, but natural gas,,,,

        ...that solar isn't going to be replacing coal, but natural gas,,

        Coal is disappearing all on its own. In 1997, coal accounted for 52.8% of the electricity generated in the US. In 2017, it accounted for 27.4%. The reason for the decline is that coal plants have been replaced by...natural gas plants.

        And now, natural gas plants are being replaced by solar plants. You could correctly say that solar is generating electricity where coal once did. So, solar is replacing coal, but there is an intermediate step.

      • Coal to natural gas conversion is very cheap and natural. So as soon as the gas prices fell below coal per megajoule they switched to gas. Easier to transport, adding a bunch of nozzles to an existing coal fired furnace is trivial, without ash removal issues it is so much simpler.

        So natural gas will kill coal very quickly. Solar will kill natural gas slowly.

        Natural gas is cleaner than coal. Thats about it. Megajoule per megajoule it emits same amount of CO2 as coal.

          Except Florida only has one active coal plant left in operation, and that is already scheduled to be shut down by the end of the year.

          Traditionally, Florida used oil-burning rather than coal-burning electricity plants. Those have steadily been converted to natural gas over the years.

      I think it varies depending on the location. In the Miami-Dade they actually use recycled automobile batteries [fpl.com]. However, I think that's probably a one-off project.

      FPL already has 18 solar farms in Florida, and at least one large-scale battery storage project at Babcock Ranch [babcockranch.com], a town designed from the ground up for solar.

      According to their 10-Year Power Site Plan [frcc.com] that was filed in April of 2018 they are still experimenting with battery configurations, and purchase through competitive RFP.
