Wonder if there’s one for blackout central — CA.

CA has had blackouts, not for lack of power, but recently, rather for liability reduction vs wildfires sparked by woefully behind the times maintenance of the grid.

Ah so such a dashboard would need to display expected vs actual.

We had capacity blackouts in 2020.

Yeah, I was part of those. Sometimes living in CA feels third-world, and due to completely preventable maintenance items.

Also huge tariffs on Asian solar panels cuts demand.

Tariffs are a thing, but there is absolutely no shortage of demand right now, and hasn't been for a while.

What makes you say there is no shortage of demand? If demand is elastic then lower price would mean more demand. I know that’s just econ101 which is often misleading, but what makes you say otherwise?

The surprising inference from me, as an energy layman, is that solar output coincides with periods of peak demand. Obviously this is seasonally adjusted, but in an era when the Saudis have solar contracts being supplied for $10USD/MWh [0], the potential profits for a solar provider at periods of peak demand seem more than sufficient to encourage investment, especially with interest rates still at a historic low for b…

I found this really interesting as well as here in New Zealand that relationship is inverted - we don't typically have residential air conditioning yet use a lot of electric heating so our peak demand is in the mornings and evenings, and most intense in the winter. This makes the business case for solar a lot trickier here as the periods of max generation (daytime during the summer) coincides with low demand and subsequently low wholesale energy prices.

Solar capacity in Texas tripled since last summer . https://www.washingtonpost.com/opinions/2022/07/21/heat-ener...

Another factor for building solar right this moment is that the price of polysilicon has jumped to the point where large projects are potentially at risk of cost overruns/delays. Growing pains.

For one, the peak price of electricity was ten times the usual low point (~$36) I'm not sure what to make of the frequency drift; federally operators are supposed to balance it out for timekeeping, among other reasons. Taking a week to get on-frequency is...not good.

TX is not a federal operator, correct? And what is the problem with drifting a bit? I know back in the day lots of peoples' clocks used it as a time reference, but that can't be very true today.

It means the power plants are over capacity is all.
