So, what gives? Where's the solar?

Being installed as fast as the fabs can churn it out? Production capacity isn't infinitely elastic, factories take time to build. Solar is growing very rapidly, for reasons exactly like this, but it's not magic.
Initial cost would be higher, but long term cost of Solar is ridiculously cheap.
Also wonder how much kWh batteries one would need for winter heating (generate at day, use at evening). Kinda feel NZ, especially north island should have enough. Over in Eastern Europe you can get recycled batteries for $150/kWh!
In the end, you'll always need a mix of supply. Or simply better insulation and efficient heat pumps rather than wasting electricity on heating at above freezing.
So much for "sometimes the wind doesnt blow" as well. Looks like they are doing just fine with their wind power in texas.
Yet Texas doesn't have such a policy statewide. Because a simple money saving idea got politicised and lots of people got convinced they were subsidizing liberal elites, rather than paying their neighbours for providing a useful service.
Also, trying to follow to the data source of the Ercot website https://www.ercot.com/ I get blocked with things like this:

This doesn't surprise me. One of my projects as an intern was to generate reports from public data from ERCOT and a few other North American ISOs (organizations that control a region's power grid). Some of them are happy to reply to a basic cURL request. Others are more particular about things like your user agent or cookies set (even sites that didn't require authentication would set a cookie on first load and would reject requests to certain pages without that cookie). A few were very particular and ran some Javascript code to serve requests that made it so something like Selenium was required.
It was a bit surprising to me how many hoops we had to jump through considering this is public data that tax payers are entitled to.
If I recall correctly PJM was the best to work with because they had a well-designed REST API and provided a developer guide with sample code.

I'm not sure if these controls are in place to safeguard against abuse. Most people don't even know these companies exist and I doubt they get too many requests. I'm assuming this is just a symptom of software sold to the lowest bidder.
All gists are actually GitHub repositories — you can clone them, branch, and commit changes. There isn’t PRs or an issue tracker, though.
(Same with GitHub wikis.)
It's easy to blame them, but if you provide any data on the web, the load you get from scrapers is insane.
Two weeks ago I even threw together a simple Twitter bot[0] because I was annoyed with some of their communications there. This datadog dashboard has been around for a while - it shows up on energy Twitter somewhat frequently when the Texas grid is having issues.
The grid being under-frequency for days at a time shows they didn't have enough generation capacity.
Outages can have a lot of causes.
I wish it were easier to see the moments when demand and capacity were at their closest, as those are the "interesting" moments.
It's only odd if you assume that any type of data presentation is always targeted to those living in the area the data is collected for, which of course is not always true. And as others have pointed out, Celsius is in fact used in the US by scientists, physicians etc. -- just not by laymen.
This dashboard gives you an overall of the capabilities and capacity of the grid.
Capacity and Demand - How much capacity the system has available against how much is being used in real-time. As the two lines get closer together, it can indicate that the grid is nearing capacity and the need for conservation or an EEA may be necessary.
Grid Frequency - While related to load, a lot of appliances keep their clocks based off of the grid frequency. Our grid is 60Hz. Deviations from that are expected and usually OK. However, anything greater than ~.5% is considered bad and a 1% variation (e.g. 59.4 Hz) can actually cause equipment damage. In fact, the reason we had load shedding back in Feb '21 was because we got down to 59.4Hz.
Wind & Solar Generation - How much of our capacity is coming from those sources. The days where Wind is down usually is when conservation notices come in.
Energy Flow to/from Other grids - How much power are we getting/sending from/to other grids. We have ties to MX, a "railroad" tie as well as ties to the eastern/western grids. We can and do import/export up to about 800 MW from those grids when needed.
ERCOT Ancillary Real Time is where things (IMO get interesting).
Supply Regulation (freq. adjustment) and ancillary supply are really the big indicators of issues. The more "supply regulation" that goes online the more we are having to adjust the frequency of the grid to compensate. If the grid frequency is too low and all of the regulation freq. up has been deployed—that's a BIG issue and indicates that the system cannot deliver enough.
If the system has deployed all of its online/offline reserve capacity, then there simply is no more generation capacity available. When things "get bad" THOSE two are the ones to watch because those are the ones that are engaged in ensuring the overall stability of the system.
Sometime in the next few years, power grid vendors will start to understand they're in the real-time information business.
All good, it's just a ton of numbers without explanations. Here's a couple very basic insights tho:
Grid frequency below 59.8 is always bad, 60 is perfect
Capacity should be at least 1 GW above demand
Demand equaling capacity is bad

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.
Honestly it's an interesting trainwreck to observe from far away. Shame that it affects real people locally.
In case you're not familiar with Ercot https://en.wikipedia.org/wiki/Electric_Reliability_Council_o...
With natural gas and nuclear, there would never be a power shortage in Texas. But for some reason people are obsessed with ugly, bird killing windmills and giant solar farms.
I believe the CA power grid gets similar attention here whenever there's any news. A post for a dashboard would've probably attracted as many upvotes.
Texas has had several power failure related disasters in recent years; which have cost many lives and much value, as well as caused shocks to the rest of the US.
Much of the rest of the US does not have those issues, or has them in only very small predictable circumstances, mostly caused E.G. by huge windstorms (trees), earthquakes, fires, other 'natural disasters'. Climate generally not regarded as a natural disaster since it's something that should theoretically be planned for. Even the windstorm example, for metro areas power should not go out. It's only poorly managed rural areas that tend to go off the grid.

For me it was relevant to answer “oh that interesting, someone posted this ERCOT data I wonder what’s going this week”
Kind of weird my comment was downvoted so heavily - but whatever. The dashboard was posted to Reddit over a year ago during DIFFERENT issues for ERCOT so it seemed relevant to find out what’s going on this time around.
