California Replaces Gas Plant with Giant, Billion-Dollar Grid Battery (canarymedia.com) 169

Meanwhile, in Southern California, nonprofit news site Canary Media reports that an old gas combustion plant is being replaced by a "power bank" named Nova.

It's expected to store "more electricity than all but one battery plant currently operating in the U.S." The billion-dollar project, with 680 megawatts and 2,720 megawatt-hours, will help California shift its nation-leading solar generation into the critical evening and nighttime hours, bolstering the grid against the heat waves that have pushed it to the brink multiple times in recent years... The town of Menifee gets to move on from the power plant exhaust that used to join the smog flowing from Los Angeles... And the grid gets a bunch more clean capacity that can, ideally, displace fossil fuels...

Moreover, [the power bank] represents Calpine's grand arrival in the energy storage market, after years operating one of the biggest independent gas power plant fleets in the country alongside Vistra and NRG... Federal analysts predict 2024 will be the biggest-ever year for grid battery installations across the U.S., and they highlighted Calpine's project as one of the single largest projects. The 620 megawatts the company plans to energize this year represent more than 4% of the industry's total expected new additions.

Many of these new grid batteries will be built in California, which needs all the dispatchable power it can get to meet demand when its massive solar fleet stops producing, and to keep pace with the electrification of vehicles and buildings. The Menifee Power Bank, and the other gigawatts worth of storage expected to come online in the state this year, will deliver much-needed reinforcement.

The company says it's planning "a portfolio" of 2,000 megawatts of California battery capacity.

But even this 680-megawatt project consists of 1,096 total battery containers holding 26,304 battery modules (or a total of 3 million cells), "all manufactured by Chinese battery powerhouse BYD, according to Robert Stuart, an electrical project manager with Calpine. That's enough electricity to supply 680,000 homes for four hours before it runs out." What's remarkable is just how quickly the project came together. Construction began last August, and is expected to hit 510 megawatts of fully operational capacity over the course of this summer, even as installation continues on other parts of the plant. Erecting a conventional gas plant of comparable scale would have taken three or four years of construction labor, due to the complexity of the systems and the many different trades required for it, Stuart told Canary Media... That speed and flexibility makes batteries a crucial solution as utilities across the nation grapple with a spike in expected electricity demand unlike anything seen in the last few decades.
The article notes a 2013 Caifornia policy mandating battery storage for its utility companies, which "kicked off a decade-long project to will an energy storage market into existence through methodical policies and regulations, and the knock-on effects of building the nation's foremost solar fleet." Those energy storage policies succeeded in jumpstarting the modern grid battery market: California leads the nation with more than 7 gigawatts of batteries installed as of last year (though Texas is poised to overtake California in battery installations this year, on the back of no particular policy effort but a general openness to building energy projects)... California's interlocking climate regulations effectively rule out new gas construction. The state's energy roadmap instead calls for massive expansion of battery capacity to shift the ample amounts of solar generation into the evening peaks.
"These trends, along with the falling price of batteries and maturing business model for storage, nudged Calpine to get into the battery business, too."

      Your data or math is broken. According to this https://www.iea.org/data-and-s... [iea.org] LiIon alone was about 1.5TWh in 2022 (it is more now). This plant here has 2.7GWh, putting it around the 0,2% mark.

      • by sfcat ( 872532 )
        You are reading that wrong. Global output of Li-ion batteries is about 35 GW/hr / year. That's actually how many batteries are made. Your article says Li-ion manufacturing capacity as in if the Li-ion factories all ran 24/7 how much could they make. Li-ion production isn't limited by capacity of manufacturing. It is limited by the amount of Li available. All that says is that governments are bad at spending money as they have vastly overbuilt (thus wasted) Li-ion manufacturing.
        • by gweihir ( 88907 )

          So you are saying these factories run at 2.3% capacity? That is not plausible at all. If that were true, most of them would just get closed and capacity would _not_ get expanded.

          Cite your sources, they seem to be bogus.

      Not sure what you mean by 'size', but automotive lithium ion batteries in 2022 were 70.6GWh in the United States alone. The 620MW that will be operational this year of this plant is less than 1 percent of the US car batteries per year. The total future ambition size is 2GWh which would put it at about 3% of the US yearly car total.

      That's just automative and the US. The total global 2023 lithium ion shipments were 1200 GWh. To hit 7% of that it would have to be a 87GWh plant, but for now it's just a 0.6GWh plant so well off from that.

      • it's just a 0.6GWh plant

        No, it's a 2.7GWh plant. Its peak output is 680MW. The rest of your point is fine, though.

  • Interesting that this project was awarded to BYD. Does anyone know if Tesla bid on the project and if so why BYD won?

    • by quenda ( 644621 )

      The fact that Tesla buys batteries from BYD (as well as making their own) may offer a clue.

  • Is it water cooled ? Solar charged ? More important, what happens when the batteries reach end-of-life ??
  • Think of how many people could have been fed clothed and sheltered for that.

    Think of how significant the 'inflation' is as the costs are passed on to rate payers, which impacts both housholds and producers.

    All to replace a gas generated we already had.

    • Why would an energy company spend their money feeding people?

      The peaking plant it replaced was too expensive to even turn it on. Natural gas can be cheaper than coal, but only for base load generation. Peaking power is way more expensive.

  • I wonder if there are batteries that cater to the specific use case of storing power for no longer than 24 hours. Conventional batteries are able to store power for months but clearly this is not required for this use case. So perhaps a much cheaper or more efficient technology exists that stores power for 24h max but does so more cheap and efficient than EV-style batteries.
    • Redox flow batteries. They're getting close if not already surpassing Lithium for cost. But they are a lot bigger and take longer to build. I think the up-front cost is higher, but they last longer. Long enough that it makes sense to build a Lithium one first to buy you the time to build the other.

    What I wonder is why flywheel storage isn't a popular alternative to batteries for fixed installations. Creating heavy flywheels isn't hard, nor does it require the kinds of toxic materials used in batteries. Tungsten carbide with a steel casing anyone? Mount them on good bearings and you should get >90% efficiency from them, and I'd guess the energy density should be higher as well. I'd have to do some calculations to see if units small enough for home installation would have enough capacity to be useful for a reasonable length of time, but large-scale industrial/commercial installations should be.

  • This gives an idea of the size of the task. The policy for net zero is to run on wind and solar. Since there are calms and nights, the question is how much storage you need to get through them.

    California demand is 25-30 GW. This installation will supply 0.68 GW for four hours. Assume that is allowing for the fact that you cannot totally discharge to flat.

    Typically wind has periods of calm when generation falls to about 5% of faceplate, for several days. To be able to move to wind and solar, you'd need

      Very similar to the UK case. Anyone trying to convert to wind and solar to get to net zero is going to run into the same problem.

    • by shilly ( 142940 )

      You absolutely do not need to build storage capacity to supply 20GW for several days. That would assume calm conditions, including offshore, with no sun, for several days across all California. When was the last time that happened? I don't mean this as a rhetorical question, it's a direct question to you: when did the whole of California last experience multiple consecutive days of no sun and no win including offshore (and many nights of no wind too)?

  • Remember when this was the Penguin's "evil plan" in the 1991 movie?
  • Clearly a battery doesn't generate power, but the main point of this unit is to store energy that would otherwise NOT be generated by wind and solar facilities because there was insufficient demand at the time. If you want to dive in to the details the keyword you're looking for is "curtailment", and you can see for example Solar and wind power curtailments are rising in California [eia.gov].

    Responsive energy storage on the grid can also provide ancillary services to keep the grid stable - particularly frequency sup

  • And, a fun amount of money to protect it all from spontaneous combustion, or at least putting fires out. And then there's the lifespan of the batteries.
  • But even this 680-megawatt project consists of 1,096 total battery containers holding 26,304 battery modules (or a total of 3 million cells), "all manufactured by Chinese battery powerhouse BYD, according to Robert Stuart, an electrical project manager with Calpine.

    Hopefully, no federal $ is going into this. Or perhaps federals SHOULD produce some $, but require that all of the cells be made in america, with american, if not western elements.
