I encourage people to read “Shorting the Grid” in order to understand decision-making on our modern grids. amazon.com/Shorting-Grid-…

Non sequitur. A grid that accomodates ITSELF uncontrolled variation in input, (a.k.a wind/solar) is by default a badly designed grid. BUT, the obvious solution, i.e. demanding FROM DAY one that input to the grid is only "contractual on demand" ( which means that Grid doesn't care if you use solar, wind, or cycling hamster on dynamo, provided you input firm bids in advance with set quantities/period/price) would have DIRECTLY ascribed the increase in costs to them , and specifically to the operators, and in a very visible way: Would you be able to sell those swathes of wind farms and solar panels in lower Spain, if all of them had a gas turbine plant smack in the middle and the country was crisscrossed by gas pipelines? @MeredithAngwin

@gbponz If you give enough money (aka subsidies) you can “sell” anything to anyone. With certain limits. For example, selling children is frowned upon, no matter how great the subsidy.

As @MeredithAngwin told me today, oil is also free, sitting in the ground. You just need to get it out, process it, and make it useful.

@runthestairs Thank you!

@MeredithAngwin That is truly appalling. I hope Julia wins big and there are punitive damages large enough to deter such behavior. I can't read the NYT, but did find this article on Wired. wired.com/story/grammarl…

Our daughter Julia Angwin on how Grammarly has used her name to make suggestions...without her knowing that her name was used, or seeing the suggestions. It is appalling. Why I’m Suing Grammarly nytimes.com/2026/03/13/opi…

@RandySVoges @isabelleboemeke It took me a moment to look this up. The proposed title was a stronger version of “I told you so, you damn fools.” It would have been a satisfying title.

@isabelleboemeke @MeredithAngwin BTW Meredith if you ever publish a follow-up edition of Shorting The Grid, you might consider the alternate title which Kingsley Amis proposed when historian Robert Conquest updated his book The Great Terror after the Soviet Union collapsed. I will leave it at that.

Thanks for admitting the obvious, but how was the entire world duped into thinking closing down nuclear was a good idea? Why were Twitter anons and nuclear bros right about this, while energy experts and world leaders were so impossibly wrong? And the most important question: What are they going to do to fix this?

Monitor Urges PJM to Make Data Centers Bear Grid Burden //www.rtoinsider.com/127963-pjm-state-of-the-market-2025-data-center-burden/ Great quote from Market Monitor Bowring: "....I think part of what the data centers are doing is trying to make things sound more confusing than they are in order to avoid taking responsibility for their load."

@MeredithAngwin Thank you, Meredith. Honored for the retweet.

Europe's self-imposed energy crisis. As @envMENTALsubstk says: There’s a reason that parable is not “He who laughs first.” Not Laffan Now, by @envMENTALsubstk open.substack.com/pub/envmental/…

@jasmine_nisar Good question. I have been happy that PJM stopped paying capacity payments to big box stores that sold the appliances.....Your question is bigger and excellent. meredithangwin.substack.com/p/goodbye-to-c…

@MeredithAngwin Whether thru EPA or DOE, is it even a legitimate role for the govt to oversee producers for energy consumption of the appliances they market?

DOE will be the lead agency for Energy Star, replacing EPA in that role. Industry groups are hopeful. I consider this to be mixed news. If there's less emphasis in DOE on appliances being ready for demand response, that would be good. If they cut too much of the actual efficiency programs, not so good. I remember the old energy hog refrigerators. utilitydive.com/news/energy-st… via @UtilityDive

@simonmaechling Hi! Another chemist here!

This is what a real science looks like. Not an anonymous account. Not a wellness influencer. Not someone selling fear. I’m a PhD chemist working with scientists every day. If you believe data should matter more than drama, follow along. And say “Hi” so I know you’re human.

This was a great podcast with @MeredithAngwin on the grid and the future of power generation. @xiaowang1984 even got a shoutout from Meredith at the end.

During cold February weather, NY ISO had about the same number of forced outages that it had in previous years. But managing them was harder. As one stakeholder put it: "...while the number of forced outages might be roughly on par with what was seen before, ..... New York had fewer resources overall to call on, which made system conditions more stressful....." rtoinsider.com/126854-nyiso-r…

It's back down to 10°F in Hartford, CT this morning. So far the New England electric grid has dispatched only a nominal amount of power from oil-burning plants. That's a welcome change from January, when oil on a few occasions provided over 40 percent of electricity.

I love it! “Energy policy fan fiction.” I wish I’d thought of that phrase. 🙂

And, "Private jets for me, #Sustainable_Poverty for thee"!
