Dan Warnick + 6,100 March 5, 2021 12 hours ago, turbguy said: Yes. Can you describe some "shift in culture" that might have made a difference to operating ERCOT as it was designed and built? Anything? I'll wait right here... What CEO worth his stock options would simply be "operating ERCOT as it was designed and built?"? The CEO's job is to make sure the big picture is identified and dealt with properly. If there is a possibly HUGE event like what the world just saw in Texas, he should know about it being a possibility, he should make it his core issue in his daily job. He/she should have come up with a plan to overhaul the system so it can't happen, and implement the plan. Part of that responsibility is to guide the shareholders and subscribers through the overhaul: identify, quantify, costs vs risks, implementation. If all the CEO is doing is collecting his paycheck and, most importantly, his stock options based on share price, then he is absolutely failing in his position and should be removed. I'll give the man credit for not taking his $800k golden parachute: it was the right thing to do and it was high time he did the right thing. The buck stops at the top. I can only imagine the number of engineers, and you of all people should know this, that had to swallow policy and sweat a bad system.

AND ANSWERED IN THE MINUTIA! Else, it WILL happen again, no matter WHAT the "culture" is... Are we after root causes, or just "heads"? Would YOU accept the answer "Who Knows"? I somewhat doubt that. If so, you may want to examine being any part of the industry. Culture is a very real thing, in business and in government, and indeed in a household. I know you know that, but I'll finish the comment. I can tell you from experience what a corrupt government does right down to the teachers in the government schools. I can tell you that a bad culture at the top of a company washes down on every aspect of the company's business. And in a household? Did you ever walk into someone's living room for the first time and go "holy cow, look at this shixxole"? Do you want to blame the government clerk? Do you want to blame the engineers for no budget to upgrade reliability and safety? Do you want to blame the children for doing what their parents do and teach by example? No. The CEO is paid well to make sure the big shit doesn't happen and that the company's growth is in line with reality. He/she is highly compensated for extremely valuable leadership and when the company fails in any major way, it is he/she that has failed, at the cultural level, and usually gets the golden parachute anyway. The only way that is not the case is if the CEO was in the middle of an overhaul and the shit hit the fan before he/she could get the ship righted. I have read nothing that tells me that was the case here. One last thing: Why are you defending the CEO? Why do you give a crap? ALL of the investigations that you have rightly pointed out need to be done will in all likelihood be done. With the CEO axed the staff gets the message that all is not as it was prior to the devastating event. That staff will be what saves them from a next time, not the CEO that led the ship to the iceberg. 3 Quote Share this post Link to post Share on other sites
NickW + 2,714 NW March 5, 2021 14 hours ago, Coffeeguyzz said: Way upthread, Mr. Clemmensen threw out an idea of having a new wind operator be required to also offer an OCGT as backup. One of the state's regulatory bodies was actually considering that as a requirement for new wind approval. (Don't know how that worked out). Perhaps a more practical alternative to this would be a commitment to install some battery storage to supplant a proportion of the wind farms output for a period of time. This would massively improve grid stability under all circumstances. For example if a large thermal plant tripped the batteries can come in at an instant and operate for an hour or two until reserve plant is bought into play. I go back to my original suggestion which is Texas will have at least several GW of emergency gensets at public buildings, hospitals, large factories. If these are bought into play earlier 9taking the demand off the grid) when the grid frequency starts to decay they can offset the situation and prevent a cascade. Diesel gen sets need to be periodically run so why not use as a short term reserve service. It lowers the costs for the owners (they get a capacity payment) and it lowers the investment costs else where because you don't need to start building OCGT / large ICE gen sets to run once in a blue moon.

Gerry Maddoux + 3,627 GM March 5, 2021 The ink spilled in talking about nature's attack on the Texas electric grid has been all over the place. Mostly germane, the jargon has at times been wild and inappropriate. It has ranged all the way from hacks mockingly blaming Texas for gross incompetence to well-informed and educated scientists and grid engineers compassionately offering suggestions and sharing data. Reading the New York Times and the Washington Post, for example, gives a lay person a much different gestalt than reading the Wall Street Journal. But so far not much if anything has been written about what is likely much more of an existential threat. From a senator's report, I understand that EMP (electromagnetic pulse) from a nuclear weapon detonated high above the United States is in the military strategy doctrine of China, Russia, Iran and North Korea. Of these, China is by far America's largest threat. That's not xenophobic, but fact, pure and simple. And if we ignore it, we could be falling into a Thucydides' Trap much larger than the one that has already subsumed the NBA. Just as the extent of the economic, physical, and soul-crushing effects of Covid-19 very likely surprised and awed President Xi, we must assume that they also wakened him to the always-present fallback possibility of biological warfare--for hegemony if matters get grim enough. The utter chaos imposed by the second-largest state effectively losing its grid has not been lost on President Xi, either. Much longer in blackness and zero temperatures, crippled by roads and runways that were rendered unusable, and Texas would have begun a logarithmic decay: death by hypothermia, pestilence, loss of dialysis equipment and operating rooms, dehydration, starvation, even theft and murder by fathers desperate to keep their loves ones alive. Texas is going to build back its grid system, and it will be much more redundant than before, and certainly equipped for the capacity demand of an ever-increasing population and the always-present nuances of severe weather. There will be blood--mostly at the top. A lot of engineers and lower-level workers very likely saw a vulnerable system and had to swallow bad policy designed by an old-boy club. This will be fixed. What I'm equally concerned about is an EMP. What happened to Texas could very well happen to massive swatches of the United States. According to administrative mandates bolstered by massive bribes barely masqueraded as incentives, we are about to quadruple electricity demand, more and more using power generated by wind and solar farms. EV charging is going ballistic. So is heating and cooling--but not from NG; instead, from electricity generated by "renewables." Ironically, with an average electricity distribution infrastructure of 35 years (dog years for power lines), we are entering a new and much-hyped "Decade of Electricity." The threat of EMP has been around so long and we've become so comfortable in our belief that we could identify a weapon and destroy it before it hit our troposphere that it--in some ways--poses a "chilling" analogy to the recent weather event in Texas. Complacency is not our friend. Not when it comes to energy-security. Our grids--yours and mine, no matter where we live--are vulnerable. And censorship, along with the continuous barrage by thought police telling us what is politically-incorrect or xenophobic, made all the worse by tiptoeing by our president and his Secretaries of State and Defense, will only make grid-security more questionable. It is a time to be nice to people, but vigilant. The world--no matter if we kill off Dr. Seuss and the rest of his ilk--is a dangerous place. 2 1 Quote Share this post Link to post Share on other sites

I criticized that, naturally, but when you've become indoctrinated into the clown world that is the EU things that make no economic sense become de rigeur. So why not build a massively underutilized generating system, raising the cost of power for all, all in the name of "green"? I mean, if you just built the gas plant you'd be $Billions ahead! The electricity produced would be dirt cheap and reliable! Logic, common sense? Thought crimes now. Did I? I have said time and time again which seems to fly past you along with the fairies and pixies.... The back up needed in Texas is already sitting there in the form of emergency Gen sets at hospitals, public buildings, large factories etc. All it needs is to be is tied into the system so that ERCOT can call on it as the grid frequency starts to decay to prevent a cascade failure. No need for any more generating plant investment (may need to moderately increase fuel storage) The owners of the emergency gensets get to offset some of their costs for equipment they have to buy anyway (win-win) Emergency gensets need to be periodically run to cycle through the diesel so why not use this to strengthen grid resilience Lots of smaller units reduce the risk from one sudden failure / failure to start Lots of smaller units spread across the state allow the operator to bring into play and stand down the exact number of units needed and in the locations where they are needed.

I got you and @Dan Clemmensen mixed up a bit. He commented back and I'd assumed you saw that, my bad. The EU interties are interesting and it is clear that king coal is holding the fort over there, keeping the grid stable while politicians take bows and claim green supremacy. French nuclear is also helping. I'm intrigued in your idea of emergency sharing and we discussed it at length before. Absent laws and major incentives I'm unconvinced altruistic behavior will win out. Back when I owned a medium data center with very expensive uninterruptable power (Liebert) and a large diesel genset, the last thing on my mind would have been sacrificing any of it to help out the utility. I had a system to keep online with maximum uptime and only that was on my mind. We had two separate grid connections from two different utility generating sources, part of the initial site selection. I sold that business and I'm glad I did, thinking about all the things that count go wrong, all the time is very wearing on a man. I heartily concur with @Gerry Maddoux's points above. The poor folks in the trenches were worried about these things and I'm confident memos were floated up the flagpole for budget money to deal with them, no doubt to be shot down so those funds could go into extending power lines to where no customers would ever be, but windmills sat. There's a world of difference between bringing a gigawatt of grid capacity to a single power plant versus stringing out the same capacity over a hundred miles to pick up megawatts at a time from wind turbines. Both engineering, but one makes pragmatic sense the other decidedly doesn't. 1 Quote Share this post Link to post Share on other sites

Take a look at this. Its an energy mix for Europe (EU+ UK) for yesterday. Peak demand is around 400GW of which coal (inc Lignite) totals about 59GW so about 15% of supply Nuclear in contrast is about 90GW and Hydro 101 GW. Its the hydro that keeps the system stable and that doesn't include what can be drawn off Switzerland, Turkey, some of the balkan states, Ukraine and Russia.

By switching it on they lift their demand off the grid helping to alleviate the supply shortfall. If the grid fails due to a cascade event they will be switching it on anyway. A more timely intervention by the collective call in of gen sets can prevent the cascade from ever happening. If the grid fails then the hospital islands itself and runs off its generators. There is no risk to the hospital. The only thing they may need to consider is a moderate increase in fuel storage if working under these arrangements. 2 Quote Share this post Link to post Share on other sites

I would think they might have had that worked out, but I just don't know. I do know that they would have been armed with abundant reserve generator capacity. You make a very good point. They most likely have grid frequency monitoring where if the frequency drops below a certain level the generators fire up automatically. On a more formalised arrangement with the grid operator, the operator can fire up the generators remotely when it perceives a need arising (probably a bit earlier than in the scenario above) . In return the owner of the genset get a reserve payment which helps offset the cost of the generator. There is a cost involved here but its far lower than investing in loads of OCGT that are only really needed every 5/10 years. Dan said earlier that the reserve capacity of ERCOT was only 8% against a national average of 15%. That needs addressing but the most practical option here is to build some more modern CCGT plant and downgrade some older CCGT as the operating reserve or at least the OCGT part of that generating plant. 1 Quote Share this post Link to post Share on other sites

Dan Clemmensen + 1,011 March 6, 2021 1 hour ago, NickW said: Wouldn't have been unreasonable in the circumstances to ask the public to avoid unnecessary usage - dishwashers, washing machines / hunt down the ghost loads etc I think that the public is willing to respond and that the response would be meaningful, but it takes awhile to get their (our) attention, and the there are limits to the amount of power the public is capable of shedding. I think the Texas shortfall was so large that any likely response would have been too small to make much difference. I base these speculations on our experience in California last summer. on 13 August, the day before our first rolling blackouts, the public was asked to cut back on usage, but we were not given a lot of guidance as to how to do it, or what parts of the state could usefully help, and the whole thing seemed fairly theoretical. As a result, only a minor cutbacks occurred, as we had a period of two hours of rolling blackouts affecting about 800,000 customers, some for over an hour. This got our attention, so when the requests to cut usage went out the next day, more people paid attention, and there were fewer blackouts, lasting for less time. On the third day, although the same record-breaking heat recurred, even more people were paying attention, and no rolling blackouts were needed. The Texas blackout was worse, so I speculate that people were less able to shed load and would have had a harder time getting the word that they could help. People also had the horrible double whammy where there was a need to conserve natural gas in addition to conserving electricity, and that would have been difficult to explain, especially to people whose cable and Internet were down due to lack of electricity. The next time a call to conserve goes out, people will respond more quickly and more effectively, but only if it happens within the next three years. After that, we will have forgotten. 1 3 Quote Share this post Link to post Share on other sites
JustMe 0 JM March 6, 2021 Texas's grid went down because a nuke reactor went down because of the cold, and the oil and gas fields also froze and went down and there was no way to get any gas from storage because very little is stored and even that couldn't be brought online because of the cold. I am sorry to say but not only does oil and gas cause climate change, it is also unreliable and unable to meet the energy needs when it is most needed. Texas needs to tie its grid to the other provinces so that it doesn't freeze in the dark when the climate change calamity plays out. It was the same story in 2011. There are plenty of turbines in the frozen North and they run just fine in the icy cold, if Texas has been cutting corners on its wind turbine installs, then that is something to look at perhaps via regulation lol. Search for live.gridwatch.ca to get a feel for how little gas contributes to that state's electrical grid, coal and the rest are non players only needed as last resort in extraordinary circumstances which is rare. The wind speeds increase during the freezing conditions making it a great time for wind energy. Quote Share this post Link to post Share on other sites
