With current technology getting through long days of sunshine linked demand is not an achievement worthy of celebration.

> sunshine linked demand The demand lags the sunshine which is why it's a non-trivial problem.

With a lot of overlap though. The correlation with sunshine is still helpful.

Texas also has higher energy demands (residential AC + industry + bitcoin friendly). Seems intuitive that they would have more to gain from larger battery infrastructure.

CA also shoots itself in the foot by having all its wealth and population in mild areas so those places run the show and nobody takes it seriously until it's a hot-summer, everyone cranks the AC, the grid keels over and then "how could this have happened". It's literally the stick in spokes meme. Sure there's some guy in the desert who's been screaming about how this stuff matters, but nobody listens to him because t…

Can you be a bit more explicit? Do you have a specific person in mind as a model of this "guy in the desert" that people keep calling a "dumb yokel" but who actually a power-grid savant or whatever? Aside: alongside your hero, there are some extremely kooky people living out in the CA desert.

2022, not 2023. That was due to one time effect of corrosion repairs. For 2023 and 2024 EDF was profitable, with net income of those two years exceeding that 2022 loss.

And I’m generally a nuclear proponent but one of the worst investments the French utility made was investing in the UKs reactor debacle at Hinkley C.

Per wiki, cost midrange is now 45 BEUR. That's ~14 MEUR/MW capacity (v. solar @ ~1MEUR/MW).

Ouch!

The electricity mix in France is still way cleaner than in California: - France: https://app.electricitymaps.com/map/zone/FR/5y/yearly - California: https://app.electricitymaps.com/map/zone/US-CAL-CISO/5y/year... And their kWh costs less than 20 Cents in the standard plan: - https://particulier.edf.fr/content/dam/2-Actifs/Documents/Of... They even offer flex prices going down as low as 12,32 Cents/kWh. Nuclear power…

Quebec has them both beat. Hydro rules! https://app.electricitymaps.com/map/zone/CA-QC/5y/yearly (To be transparent, there's controversy around calling hydroelectric renewable.)

I am a bit biased, as an engineer who works exclusively in hydro powerplants, but i think they're awesome too. With that said, it's becoming more apparent that in addition to the biosphere issues they cause, they also cause a pretty significant amount of methane to be released. https://www.hydropower.org/blog/new-study-sheds-light-on-res...

It would put me out of a job but I'd still rather see a surge in nuke generation and solar with storage, at least until we get fusion figured out.

> Or we could treat nuclear rationally and stop increasing the price three orders of magnitude past diminishing returns Who is we here? Do you have examples of any countries having successfully done what you are proposing?

China https://x.com/bataille_chris/status/1981476968202752109

And still even China is adding as much solar as their total nuclear capacity on a yearly basis.

CATL is just dumping

CATL had a profit of $2.6B last quarter on sales of $15B. That indicates they're pricing well above cost rather than below it.

dumping doesn't depend on profit or loss. Also the legal definition of dumping is less-than-the-"normal value." (see Article VI ANTI-DUMPING AND COUNTERVAILING DUTIES of GATT 1994).

But then China is a non-market-economy, so none of these rules apply in a hypothetical anti-dumping case -- ie, China's local price, or "normal value" doesn't matter.

Are you saying Texas doesn't have much rooftop solar? That's surprising. I suppose largely due to low electricity costs making the investment not worth it? (And, I suspect, secondarily, utilities not really incentivizing it)

And the hail, I suppose.

I never thought about the impact of Texas hail storms on solar energy. Is there an industry standard practice to shield the panels during hail storms? Or do they use stronger glass? I am curious to learn more.

> California hasn’t issued an emergency plea for the public to conserve energy, known as a Flex Alert, since 2022. Feels like that statement deserves to be contextualized with weather data. There were a few summers leading up to that where all of the major metro areas shared concurrent record high heat days, and sometimes coincided with poor air quality from wildfires (meaning more people closed their windows and ran…

Electricity prices are set by the French government not the wholesale cost or cost of production. Which is why EDF - the operator of the French nuclear fleet - regularly posts massive losses. Like the €18 billion loss in 2023. https://www.lemonde.fr/en/france/article/2023/02/17/france-s...

It should be noted that most of EDF's massive losses are due to the ARENH. The European Union insists that EDF must sell energy at very discounted prices, so that third-party "providers" can make an entry on the energy market. The idea was that they would eventually sell their own energy supply, but most just pocketed the difference between the dirt-cheap energy & what they charged customers, then ran away the moment…

So that's an European thing? huh. We have this in Romania - a couple years back when the war in Ukraine started just as the green deal took effect, the gov started spending like crazy on subsidizing energy. But they did it in a convoluted way with a layer of intermediaries that basically were allowed to invoice the state for price differences from arbitrary price levels. Almost "I'd like to sell at twice the price but you're not letting me, so gimme the difference" - if not exactly that.

I'm not sure if I'm feeling better or worse that it's a EU invention. Either way, it's hellof a corrupt practice.
