WE KNOW FOR A FACT THE SUN WENT OFFLINE LAST NIGHT
Speculative, but hardly improbable.
Weak winds and solar power are routinely cited in ERCOT alerts, but thermal plants tripping offline gets hidden behind a screen.
WE KNOW FOR A FACT THE SUN WENT OFFLINE LAST NIGHT
Last night, ERCOT skipped the level 1 alert at 7:30pm.
What caused the sudden drop in frequency and energy supply?
i.e., an occluded front will bring partly cloudy conditions to north Texas, then the sun will set.declining solar power generation into the afternoon & evening hours

even if it's "just weather," Texas needs to be prepared for what it is and what it will be.

https://www.douglewin.com/p/ercot-ha...ions-to-answerThe agency put out a press release citing low wind and the sun going down (as well as high heat and demand) for the disruption, even though wind was consistent with forecasts and delivered 60-100% above what ERCOT defines as “low wind” in its Seasonal Assessment of Resource Adequacy (SARA). As Katie Coleman, an attorney for the Texas Industrial Energy Consumers, told Bloomberg, “We knew wind was low and demand was high, but there was no reason to expect conditions to be worse than many other days this summer.”
ERCOT has yet to address an apparent 400-megawatt drop in coal output during the same hour frequency dropped yesterday. More than that, ERCOT hasn’t addressed the apparent congestion and curtailment issues — which they might have caused — that reduced the flow of electricity from South Texas to North Texas.
ERCOT’s own posted data also shows that there was a 1,000-megawatt drop in wind output right after 7:00 p.m. — even though there was no reduction in wind speeds.

Transmission emergency: too much wind and solar.

Two years after Uri, Texas fails to deliver energy reliability.
https://www.kut.org/energy-environme...ergy-emergencyDuring the power emergency, ERCOT worried that a transmission line that runs power from South Texas to the rest of the state could overload with electricity. That put the transmission line itself at risk of, essentially, frying. Rather than risk the line tripping off or breaking down, ERCOT cut the flow of power running over the system right when people needed it most.
Given the fact that the power was moving from wind-rich South Texas, it seems likely it was wind-generated electricity that was curtailed.
That complicates the grid operator's frequent suggestions that low wind output is responsible for this summer’s requests for energy conservation. There was, apparently, wind power being produced in the state on Wednesday. The grid simply didn’t have the capacity to move it.
“All the wind that was on in the south was struggling to get to Dallas to help meet demand,” former ERCOT head Brad Jones told Bloomberg. “So right in the middle of this, ERCOT had to reduce generation in the south to prevent that line from being overloaded.”
Jones says ERCOT needed to cut about 1,000 megawatts. That’s about enough energy to power 200,000 homes, a significant amount of power in an energy emergency.
In an email to KUT, ERCOT confirmed that “a transmission limitation in the south Texas region that restricted the flow of generation out of South Texas to the rest of the grid” factored into Wednesday’s emergency.
On Thursday, current ERCOT CEO Pablo Vegas wrote a letter to the Department of Energy requesting permission to suspend emissions rules for some power plants, allowing them to operate during this time of high energy demand in Texas.
ERCOT says it needs to allow power plants to pollute more than usual in order to keep the lights on.
In the letter, Vegas outlined the reasons for recent grid instability, citing the transmission congestion that the grid operator has been aware of "for a few weeks." He writes that trouble on the transmission line “required a decrease in output from certain units” on Wednesday and said the same problem may occur Thursday and Friday night as well.
“Such an overload would require ERCOT to reduce output of resources impacting the loading on that element, exacerbating ERCOT’s scarcity concern,” Vegas wrote.
The Department of Energy approved the request.
Natural gas interests have lobbied against investing to upgrade transmission lines to deliver wind power where it is needed.
the flooding in Greece is mind-blowing. they just got a years' worth of rainfall in a few days.
Figures.
Who's lobbying to keep us off the national grid?
Those blue low prices seems to stop at the first major city of San Antonio. Houston also got left out.
Just a little bit further and we could have been in the light yellow.
How unfortunate...
"We are business friendly Texas. We dont need California ideas. If our residential customers freeze this winter thats just the way it is."
The more ERCOT refuses to answer questions, the more libs get to speculate on unsavory money grabs.
You would think they would want to explain their problems clearly and stop all this "gossip"
RELAX. COOLER WEATHER IS COMING SOON.
THE UNRELIABILITY OF SOLAR POWER AT NIGHT IS UNQUESTIONED BY ALL CREDIBLE AUTHORITIES, SAVE THOSE POSSESSING BATTERY STORAGE CAPACITY...
...OR TRANSMISSION LINES SUFFICENT TO DIRECT THE ENERGY TO MEET PUBLIC DEMAND EFFICIENTLY.
