Grid update: Still extremely low chance of outages. This front is not extreme & won't bring us anywhere close to the 77GW of demand in Feb.

BUT there is a warning sign for future extreme cold: there are 10+GW of thermal plants offline right now.
1/🧵 #txlege #energytwitter
A little more info on that. You can see the amount of outages at the link below. It's updated every hour. (You have to add columns C-F to get total thermal outages).

It adds up to 10,114MW (or 10.1GW) of nuke/gas/coal plants offline right now. 2/

ERCOT forecasters continue to struggle w/ demand on winter mornings. Idk why they continue to miss but ERCOT needs to address this. My guess is that they're undercounting electric heat. Note: FERC & NERC specifically said ERCOT needs to improve this. 3/
Some have noted how low prices are this morning despite moderately high demand. First of all, demand is not that high (53GW). It's less than we had at peak in October or April.

Second, wind is doing quite well this morning.

Again, there is an extremely low chance of systemwide outages. There are localized outages (~11k, w/~3k in the Houston area). These are likely caused by high winds. This is one of many reasons why no one should guarantee there won't be outages. Too many variables #txwx #txlege 5/
Peak demand from this cold weather will be tomorrow morning, projected to be 60.4GW but will likely be a bit higher. We should have enough power to meet that easily.

This is *not* an extraordinary, unusual, or extreme cold front. We get these basically every year.
#txwx 6/
The biggest questions as we prepare for potential extreme cold:
1) Why are the projections of demand still so far off
2) Why are there so many thermal plants offline?
After all the inspections, etc., 10GW (15% of the total) is quite high.

Best books I read in 2021. Lmk which ones you read which you think I should read too. This is an incomplete list but includes most of what I read this year.
Overstory by R. Powers "The hottest year ever measured comes & goes. Then another. Then 10 more.. Species disappear. Too many species to count..Things are going lost that have not yet been found. Look at the life around you; now delete 1/2 of what you see"

Ministry for the Future by K.S. Robinson.
"The invisible hand never picks up the check." Texans will be remineded of this often in coming decades as the costs of Feb 2021 are paid. Great book about what 2035 might look like given the heating of the planet. rollingstone.com/culture/cultur…

Yesterday, w/ no media availability or even press release, ERCOT released its Capacity, Demand & Reserves (CDR) report. As has been a pattern lately, the communications with the public about issues of widespread conern is sorely lacking. #txlge 1/🧵

kvue.com/article/news/l…
Just this week, ERCOT CEO Brad Jones, in an article about political interference at ERCOT, said releasing a similar report (the Seasonal Assessment of Resource Adequacy, or SARA) in the same way was a "mistake." But nothing seems to have changed. 2/
texastribune.org/2021/12/28/tex…
The difference betw than the SARA & CDR is that the SARA looks at the upcoming season while the CDR looks several years out.

3 main takeaways:
(1) absent changes, these reports aren't useful
(2) climate change isn't considered
(3) renewables are increasing reliability

A presentation from @NERC_official to an ERCOT working group provides more info on causes of Feb. outages & on possible gas market manipulation. NERC’s Thomas Coleman says it wasn’t power outages that caused gas to fail and that “price majeure” is being investigated. #txlege 1/🧵
The presentation is linked below. Coleman said FERC is investigating so-called "price majeure" when gas producers/suppliers withheld contracted gas in order to get higher prices. More on this later in the thread. #txenergy 2/
ercot.com/files/docs/202…
NERC’s Coleman disagrees with the Railroad Commission and some O&G spokespeople that power shut offs caused gas supply to fail, saying we had "massive freeze-offs" & Texas "didn't have requisite winterization so gas had to be shut it." (cont) 3/

@PUCTX meeting starts in a few minutes (9:30CT). Lots of agenda items, including one (#52373) on the future of the ERCOT electric market w/ major customer cost and reliability implications. I'll tweet about it here.
Livestream here: adminmonitor.com/tx/puct/open_m…

I put together two threads on the staff memo with the proposed changes.
For reference, the memo is here: interchange.puc.texas.gov/Documents/5237…
Explanation of Phase 1 proposals here
Explanation of Phase 2 proposals here:

#energytwitter
There are lots of members of the public in the room with what appear to be paper mache power lines (hard to tell from the feed). Public comment period was changed to 10:30, would normally be at 9:30.

Market design changes will be discussed at the end of the meeting.

The final @PUCTX meeting of 2021 is tmrw & Cmsrs may make some decisions on market redesign that could add billions in customer costs. The previous🧵summarized proposed Phase 1 changes. This one focuses on the items in Phase 2 & summarizes comments
#txlege
interchange.puc.texas.gov/search/documen…
There are 3 major proposals in the Phase II Market Design Proposals section:
- Load Serving Entity Obligation (LSEO)
-Dispatchable Energy Credits (DECs) (aka Dispatchable Portfolio Standard)
-Backstop Reliability Service (BRS)

I'll explain each below
#txenergy #txlege
The Load Serving Entity Obligation would require each retail electric provider (REP, e.g. TXU, Reliant, etc), municipal utility, & co-op (any entity that serves customers) to purchase capacity ahead of when it will be delivered. This is essentially a form of a capacity market

"'I think demand would exceed supply and some customers would be without electricity' if there's another bout of bad weather comparable to the storms in February, said Beth Garza" of @RSI

"We are only as strong as our weakest link,"said @TimMorstad of @AARPTX. “There has not been nearly enough urgency at the @txrrc...to make sure that gas-fired electric plants will have gas if we get extreme cold"

"'If we get the same weather, we will have outages' attributable to an overmatched power grid, said Doug Lewin... 'They may not be as (widespread), and they may not be as long-lasting — but we will have outages.'"

2 biggest reasons: lack of regs for gas supply winterization &...
