Rolling Blackouts in California Have Power Experts Stumped (nytimes.com) 260

Energy experts are bewildered as to why the manager of California's electric grid called on utilities to cut power to hundreds of thousands of customers over the weekend. "They said that the utilities had plenty of power available and that the blackouts weren't necessary," writes Ivan Penn via The New York Times. From the report: "They set it up like this is a historic event," said Bill Powers, a San Diego engineer who provides expert testimony on utility matters before the state's regulators. "This should not have triggered blackouts." The California Independent System Operator, the nonprofit entity that controls the flow of electricity for 80 percent of California, said it acted after three power plants shut down and wind power production dropped. It also cited a lack of access to electricity from out-of-state sources.

The energy experts noted that the peak electricity use over the weekend fell below peaks in other years, when utilities were able to handle the demand. They also said the operating reserves of power available to the utilities were higher than the 3 percent level where California ISO has traditionally ordered a reduction in electricity use. "It's just misleading to say that it was because it was a hot day," said [David Marcus, an energy consultant and former adviser at the California Energy Commission]. "I think they were being overly cautious." Saturday's peak demand, according to Mr. Marcus, reached 44,947 megawatts, much lower than the 46,797 he saw on Friday. But both of those amounts fell below the peak year for electricity use, 2006, when demand reached 50,270 megawatts, followed by 2017 with 50,116, according to data from California ISO. [...] What happens in the days ahead will continue to test Californians and the electric grid as California ISO forecast electricity demand Monday at near all-time peak levels.

      Real ecologist libs and left must really learn to shield themselves from the anti nuclear crowd. Hell there's not so ridiculous theories that the German anti nuclear greens were pushed by pro coal lobbies following Chernobyl and now Germany still relies on coal in areas whilst they've shut down many nuclear plants. In some places energy stability can be helped with hydro (storage) or the like but that's not in most of the world so until we find the holy grail of fusion or the like we'll need these plants. Stupidly enough the earlier mentioned greens also opposed more funding for fusion research "in favour of existing green tech". It's like they're hellbent or being more damaging to their cause than the few actual climate change denialist.

      Nope. Nukes are unsuitable for anything except base-load. They take far to long to adjust their power output for anything else. Delivering too much power is just as problematic as too little. Hence it would not have made one bit of difference.

      San Onofre had its own problems. It is vulnerable in the same way that Fukishima was, and was literally on the beach. It was shut down when replacement steam generators did not work. Upgrades designed to last two decades were found to have premature wear in tubes that were only a couple years old.

    ...presser this afternoon. Hidden in it was this little bit, which Democrat-run news outlets are suppressing:

    "We are committed to radically changing the way we produce and consume energy and we are creating now and have more jobs in this green sector than we do in the fossil fuel space. So we see it as an economic imperative and we see it as a moral and ethical imperative as it relates to the kind of world we’re going to leave, the kind of state nation we’re going to leave to our kids and grandkids. And we are not backing off on that commitment, quite the contrary. But in the process of the transition, in the process of shutting down, understandably the desire and need to shut down polluting gas plants, and a desire to go from old to the new. In that transition and the need to shut those down, comes the need to have more insurance, comes the need to recognize that there have been by definition demonstrably, in the last few days and what we expect over the next few days, gaps in terms of that reliability. We cannot sacrifice reliability as we move forward in this transition, and we’re going to be much more aggressive in focusing our efforts, and our intention in making sure that that is the case. We need to make sure that we have a demand-response system and we have reliability that meets the expectations that we have all forecasted around issues of climate change, and around the prospects that this is not the last “record-breaking” historic heat dome and experience that we will have in this state, or in this region, or in this nation or in our hemisphere, in our lifetime, quite the contrary." - Gavin Newsom

    and also:

    "We identify the peak hours, roughly 3:00 PM, about to 9:00, 10:00 PM. Let’s say 3:00 to 10:00 are the peak hours. I can explain in a moment why those evening hours become the most precious in terms of our concerns, particularly as it relates to sun going down, the utilization of solar. The fact that while we’ve had some peak gust wind events across the state have been relatively mild. By the way, that’s a good thing from a fire suppression perspective. That’s unfortunate moment as it relates more broadly to addressing the episodic nature of the renewable portfolio of which we are prideful in the State of California, but vulnerable to in these conditions that I have stated." - Gavin Newsom

    The problem is a really simple one which a great number of people predicted years ago when the Democrats became so powerful in the state that they now ignore all opposition in the legislature: They shuttered nuclear plants, oil-fired plants, coal-fired plants and hydro plants. All they have now for significant power generation are wind, solar, biofuels, and nat gas... most of that capacity (by type, not volume) is variable and unpredictable with only nat gas available for surge production. When you get very hot weather as CA does several times per year, you sometimes get clouds and a lack of wind... so those sources reduce and when you have severely limited nat gas plant licenses because you have committed to eventually eliminating that too, you are already using most of your gas generators and lack the ability to bring much more online.

    We used to live in a free market economy, where we got quantity discounts on stuff including water and electricity. We now live in a much more controlled economy run by people with Marxist leanings and we have rationing. Gavin Newsom and his legislature have no solutions other than "conserve!" (i.e. use less than you want/need because there's not enough to go around because government has caused an artificial shortage in order to serve some ideological groups). The man even admitted in his presser:

      That's interesting. I came to a similar conclusion based on completely different, non-political evidence - looking at the CSIRO dashboard data, this looks like an actual power shortage at around sunset due to the classic solar duck curve, and the figures quoted by the New York Times to claim there was no shortage are misleading. They point to the fact that CSIRO had a 12% operating reserve at 6 PM, and if you go to the dashboard [caiso.com] and view the renewable energy graph from Friday the 14th using the dropdown there's a rapid dropoff in solar output, which is already down to 5.2GW at 6 PM and drops to basically zero over the next hour and a half - some quick back of the envelope math shows that alone would consume roughly all of the operating reserve. Even if the instantaneous figures looked OK, there was an imminent shortfall due to something literally as predictable as the sun setting in the evening.

      There are also a couple of other interesting things in the 2019 resource assessment this article is based on that it fails to mention. Firstly, total supply isn't the only constraint - apparently there's also a risk of "shortages of upward ramping capability" which "are most prevalent in the late afternoon when solar generation output decreases", and this was considered to be a more likely problem that total supply shortages. Basically, they might have enough total supply on paper, but some of it would be unable to ramp up fast enough to keep supply and demand balanced. You can see the cause of this sharp ramping requirement on the net demand graph on the dashboard - actual demand slows down towards the peak, but net demand minus solar and wind keeps increasing rapidly right to the peak due to sunset. Secondly, it predicts that the highest risk period is pretty much right when they had blackouts: "The CAISO will be at the greatest operational risk during late summer as the availability of hydro energy wanes and potential high peak demands in neighboring balancing authority areas decrease the availability of imports into the CAISO. The continuing decline in dispatchable generation as gas units retire creates further challenges for meeting the CAISO flexible capacity requirement and the peak demand, which is now occurring later in the day when solar output is at or near zero."

      • "Basically, they might have enough total supply on paper, but some of it would be unable to ramp up fast enough to keep supply and demand balanced."

        Shouldn't a power company that's been in business for over a century be able to predict that demand and have the resources on line in time to avoid blackouts?

        • Even if you predict a shortage, how would you ramp up the sun and wind?

          Solar and wind are great, as long as you donâ(TM)t need to rely on them. Germany has twice its needs in terms of GWh in potential production capacity from solar and wind.

          Their total energy consumption from solar and wind stays hovering around the 13-20% range and people are paying upwards of 30c per kWh, though even though some times of the day they are selling energy to neighbors, most of the time they are buying nuclear from Franc

          • Even if you predict a shortage, how would you ramp up the sun and wind?

            That is not the argument. If all they had was solar and wind, then they wouldn't have enough on paper either.

          • Germany has twice its needs in terms of GWh in potential production capacity from solar and wind.

            That's ludicrous; if that were true, they'd be done with the energy transition already. At 50% curtailment you're near 100% RE penetration with minimal storage.

          • Last year 34.5% of German electrical power came from the sun and wind. As for France, Germany is a net exporter of electrical power. It only looks like Germany buys a lot from France, but in reality it is transit from France to Poland and Austria. Germany just happens to be geographically between them.

        • by makomk ( 752139 )

          Being able to predict demand isn't enough - as I understand it, a lot of these power plants have fundamental design limits on the rate at which they can ramp up power output and how low an output they can operate at. Remember, you're not just turning coal or gas or uranium directly into electricity, you're using it to heat up steam and pump it through massive turbines, and if you ramp up the heat too quickly different parts of the massive building-sized equipment expand at different rates and the whole thin

      Did you really just say we can't predict the weather? Or are you saying that when supply falls below demand (the classic economic problem [wikipedia.org]--unlimited wants but limited resources), the only way it should be solved is by increasing supply?

    Disclaimer: I work for a utility, and get the gossip. These are personal opinions, not my employers.

    This isn't a mystery, the people running the grid just don't want to admit the cause. California is currently dominated by intermittent generation. It has been getting away with it until now because they hadn't quite shuttered enough of their baseload resource, and they were relying on import power from nearby states. When those states were hit with a heatwave, there wasn't any day ahead or same day resource to procure. They used to have nuclear plants, and a few baseload gas plants that would have ramped up to take advantage of the high power prices in a heatwave... now they don't.

    The article mentions that they CAISO supposedly had enough reserve, but there are real headwinds in the utility industry that are making even that harder to count on. With fewer fossil units to rely on, the remaining plants run harder and wear out faster. Maintenance gets harder to schedule, because those resources are needed and the grid operator has the authority to reschedule maintenance even over the objections of the utilities. Additionally, with the constant threats of closing down those plants the plant owners aren't going to make any major investments in them. No one is going to invest millions in a plant that the governor might order scrapped in a couple years, or that might be uneconomic to run under the current reimbursement scheme if a carbon tax is implemented. The plants will become less reliable as a result, which is a battle that is being fought all over the country. I'm sure COVID isn't helping either... I'm personally aware of a few instances where outages have been shifted or extended because large populations of contract workers caught COVID mid outage.

    Frankly theres going to have to be a come to Jesus moment where someone just bites the bullet and develops a scheme to ensure profitable operation of those fossil units through the renewables transition period. It will suck politically, since people have been fed the unicorn farts version of renewable power capability and that will have to be walked back. But I can guarantee that if they stick a bunch more batteries on the grid with the markets structured the way they are, those batteries will suck away any remaining profitability of these baseload and fossil peaking plants and the utilities will try and walk away from them. CAISO can stop those closures for a while, but eventually the owners will either sue to exit or go bankrupt. The battery systems being built are designed to shave the peak profitability off of each day, not cover an unexpected grid disruption because the wind didn't blow or brushfire smoke blotted out your solar field.

    Higher level, I have trouble rationalizing a world where renewable energy dominates in a wholesale market system. You're trying to promote power that is inherently less reliable and more expensive in a free market system, via an ever increasing array of rules and taxes and subsidies. If you really want renewables, admit the wholesale markets no longer meet your goals and either reestablish the utility monopolies or buy out the generating resource and make it a publicly owned venture like the water system is.

      Except it's actually cheaper. You said it yourself - the others can't compete.

      The rest of your analysis might be right for California, but there are grid operators elsewhere that face similar problems to a much greater extent and manage to solve them without blackouts (or curtailing for that matter).

      And yes, you need to develop a market for longer-term reserve capacity. These things are not rocket science.

        "Can't Compete" depends a lot on the rules of the game, doesn't it. The energy markets are structured in such a way that they favor renewables, as they don't weigh any cost of intermittency against renewables and you can buy and sell power with high certainty. You could just as easily structure a market where a generating resource has to bid into a market at some yearly minimum capacity (say 40% of max) guaranteed by the generator outside of maintenance periods declared in advanced to the ISO/RTO.

      Subsidizing the grid has-fired generators is likely unnecessary— simply allowing rule 6 (IIRC, been a while) interties with backup generators in buildings can get you the missing 5GW capacity for the 30-50 hours per year it is needed (until batteries are available).
