#ERCOT grid update: Things will be tight on the grid today and tomorrow — very tight. ERCOT projecting 82.9 gigawatt peak @ 4pm and a spread between supply and demand of only 1800 megawatts tomorrow around 7pm. #txlege #energytwitter 1/ 
Solar power is having a massive impact on the grid this summer. Without it, we would be in serious trouble and have a much higher likelihood of outages. #Solar will top out right at or above 12GW and... (cont.) #energytwitter #txenergy
... is still producing ~9GW in the hour of tightest reserves. The 3+GW of batteries in ERCOT are mostly providing backup reserves in case of shortage (like when a major power plant goes offline like a nuke did last week) but is also injecting 500MW to the market when needed. 3/

Chair Lake starts by saying it was "misinformation" that extremes weren't included in the study. They in fact did not include Uri.

The Texas Senate dealt a major setback to the efforts of the PUC Chair & some generators attempting to redesign the #ERCOT market, telling them to hold off. The PUCT's biggest mistake? They never defined the problems they're trying to solve. 1/🧵

Unfortunately, it seems that #txlege is repeating that mistake. I think there are three major problems we need to solve: (1) prolonged extreme winter storms (2) hot summer evenings & (3) cost.
*There is no one thing that will solve all of these problems*

We need to identify & diagnose the problem correctly. Acc'g to @FERC & @NERC_Official, during Uri, Texas had massive demand (spiked by inefficient heat) & frozen gas supply & power plants (made catastrophic by lack of effective regulation). #txenergy 3/
Big day at #txlege today. Hearing in Senate B&C focused on fixing the grid, proposed ERCOT market changes and in Sen Natural Resources on economic development programs (incl. for energy) and implementation of a bill that bans state investment in sustainable investors #txlege 1/🧵
FERC & NERC released their winter reliability assessment & it's not good for Texas. In a Uri-like event we would be short "by about 19.7GW," almost as much as Feb. 2021. To the suprise of few, the ERCOT grid still has major problems.

"For extreme winter conditions, such as occurred during Winter Storm Uri, ERCOT indicates the need to allow for a resource derate of 11.5GW. This would reduce available resources to 64.3 GW for an extreme winter condition, which is below the extreme winter peak load of 84 GW...
"...by about 19.7 GW. During extreme winter conditions, while ERCOT can gain 1.6 GW of benefit from operational mitigations, this still leaves a shortfall of up to 18.1 GW. These above-normal winter peak load and outage conditions could result in the need to employ EEAs...
Demand stayed just below 80GW today. Large customer #demandresponse in the form of a rate structure called 4CP (more in this thread) helped to increase reliability and lower costs. Large customers are paid for their reductions. Small customers are not. 1/🧵

We won't have a reliable and affordable grid without demand flexibility. It’s possible—maybe—to white knuckle it through a summer with aging power plants at an extra cost of billions of dollars each year. But there’s a better and cheaper way...

To have a grid that is reliable and a market that is affordable, regulators need to figure out how to incorporate demand flexibility into market design.

#ERCOT update: New weekend record broken yesterday w/ 77.4GW; expected to be ~77.5GW today. Very low chance of outages today, somewhat higher (though still low) tmrw when 80.5GW expected.
At 9AM, 6.5GW of gas/coal is unavailable, up from 4.9GW yesterday AM.

Yesterday, 500MW additional thermal (gas/coal) went offline as the day went on and overnight another 1000MW dropped. Hopefully some of those will come back on as the day goes on.
Remember, if there are rolling outages, they are likely to be short duration, nothing like Uri. 2/

If you want to help, pre-cool your home or business in the AM tmrw. In a well functioning market, if you choose to help, you'd be paid to do this. This function would be automatic & you'd keep the thermostat where you want it in the PM, just a little cooler in the AM. 3/
@Tesla & @ERCOT_ISO are holding a workshop on changes proposed by Tesla to enable more local power sources to contribute to grid reliability & lower costs. @ArushiSF is kicking off the workshop w/ an overview of virtual power plants

ercot.com/calendar/event…
Virtual power plants (or VPPs) are aggregations of distributed energy resources, or small energy sources close to or at homes and businesses. Take enough small storage or solar or reductions in demand and add them up and you can reach levels that add up to large power plants.
It should surprise no one that the #ERCOT grid isn't fixed. There's a good chance there will be outages at some point over the next 3 days. Here's a look at what's going on.

A LOT of thermal power plants are out for maintenance (~16GW) & Friday, more broke: 6 gas plants = to ~3GW, roughly an Austin worth of power. I'll get into why power plants are breaking below.

Here are four key things to remember as Texans spend the weekend obsessively checking @ERCOT_ISO’s dashboard to see how the grid is holding up. 3/ ercot.com/gridmktinfo/da…
This Saturday, ERCOT expects 69.3GW of demand, an insane amount for a weekend in early May.
Temps likely to be ~92-93 in DFW and Houston, 95 in Austin, 100 in Midland & 104 (!) in Laredo. These would likely be records (or near records) for May 7.

#txlege #txenergy #txwx 1/5
I believe the previous record demand in May is ~67GW & all time summer peak is 74.8GW. That we would reach that much demand on a Saturday in May is extraordinary. Usually demand is much lower on the weekends. Extreme weather from #climatechange is already happening.
#txlege 2/5

#ERCOT expects 20GW of thermal plants to be offline. Wind expected to be @ 12GW & solar's likely to break a record ~9GW. I expect every battery on the grid will be ready for peak @ 5pm. Still, there will likely be tight conditions. Buckle up.

First off, I do NOT expect outages this evening. I could be wrong but despite the graph below, w/ temps in the 40s in Houston, there shouldn't be any issues tonight.
But this highlights why storage and dispatchable demand response are needed in ERCOT right now.

Demand is high bc inefficient heat is driving the peak higher than expected. Because we have very little committed, paid residential #demandresponse, and most of that peak is residential demand, there's little ERCOT can do about it. This is a policy failure. #txenergy

Note that the mismatch between supply and demand is not large, and doesn't last very long. If we had more storage and more dispatchable #demandresponse, this wouldn't be an issue at all.

The memo is from staff but is quite obviously reflective of Chairman Lake's position. The first thing in it is Operating Reserve Demand Curve (ORDC). This was created after the 2011 winter outages (and near misses that summer). It adds $ for generators in scarcity conditions.
Big day @PUCTX as two new concepts are introduced & discussed by Commissioners and stakeholders:
*Dispatchable Energy Credits from Cmsr McAdams
*Strategic Reserve Service from Cmsr Cobos
I'll tweet about it on this thread and put some key links below. #txlege #energytwitter

The dispatchable energy credits would come from a kind of Dispatchable Portfolio Standard akin to the Renewable Portfolio Standard and renewable energy credits. There are traded RECs for renewables, there could be traded credits for DECs soon.

Cmsr Cobos proposal is to take a phased approach with a lot of quick actions to increase resilience and reliability while building toward a Strategic Reliability Service, mostly designed for winter, which is described here:

ERCOT's Jones tells Carrollton City Council: Generation fleet lost 50,000MW because of equipment failure and lack of fuel supply. That's equal to all of California's peak and was more than half of Texas' entire generation fleet.
#txlege #txenergy
#txlege #txenergy
When we lose supply, we have turn to the load side to keep balance. We turn to large facilities that have given us the ability to turn down their usage. (he's talking about #demandresponse which we need more of!!!) Once that's exhausted we have to turn off residential customers.
This work session at the @PUCTX is starting now. I will tweet about the discussions throughout the day on this thread.

They begin by delaying a decision on HCAP, the $9000MWh price cap until they've decided on ORDC (Operating Reserve Demand Curve) as the two are related. Their analysis of ORDC change impacts is not ready so they will hold off on any decisions on either.
Tmrw, @PUCTX will hold an extraordinary work session w/ implications for all Texans w/in ERCOT and relevant broadly to folks who care about energy everywhere. They’re considering about 7-8 different market redesign proposals. Some context in this 🧵. #txlege #energytwitter 1/
First, a few absolutely critical big picture points: (1) no amount of market redesign will prevent winter outages if gas supply is not weatherized which, as far as anyone knows, it is not. #txenergy 2/

Point (2): In Feb, our problem was not capacity. We entered Feb with 40+% extra capacity in ERCOT but 50-60% of it didn’t operate. If the PUC focuses on adding capacity, it’s solving the wrong problem. Need to focus on capacity that can operate in extremes

Starting now. After brief opening statement by Chair Schwertner. Sen @whitmire_john asks why do we have to incentivize power plants to do what they're supposed to? Sen Nichols says they're profit seeking companies and they won't invest unless they can make money.
Whitmire responds: are you talking about providing government subsidies for gas generation? Tells Nichols he's sounding like the Biden Administration. Not sure why we would throw incentives at thermal generation.

Texas' energy woes will persist, and costs will be higher, unless demand side resources like #energyefficiency and #demandresponse, #solar and #storage, are deployed at scale. Alison Siverstein wrote a great piece in @UtilityDive about this. A quick 🧵
utilitydive.com/news/fix-texas…
utilitydive.com/news/fix-texas…
Silverstein is a former FERC & PUC staffer w/ decades of energy experience. She wrote that Texas policymakers and the @PUCTX and @ERCOT_ISO need to "shore up grid reliability by aggressively managing electricity demand, not just throwing money at supply-side measures." #txenergy
She writes that over the last decade TX population increased 16% while energy use increased 20%. Much of that increase is driven by inefficient homes & buildings. We have #energyefficiency programs in Texas that deliver savings at 1 penny per kWh. Try to buy energy for that!
