If only we had something that could transfer power between regions...? Although the map is looking pretty red everywhere - maybe ERCOT could be exporting?

Gonna be a long hot night on the east coast. @gridstatus.io
Check out the prices in NYISO - almost $1,500/MWh.

@gridstatus.io - great shot of the heat wave driving up prices across the Eastern Interconnect. But Texas? Doing just fine thanks to solar, wind and storage - prices are muted even at 6:00 Central.

Check out the ERCOT Large Load queue. F*ing wild. 156GW on an 80 GW system, more than *doubled* since December. 20 GW under study (pretty firm!).

Here's Adam Keech, VP at PJM, stating that inter-regional transmission won't help PJM "because other regions don't have excess capacity" - has he not hear of coincident peak?
This is from the FERC conference on Resource Adequacy last week.

Look at this gorgeous chart from @gridstatus.io on the energy transition in California. Those that said solar would not be able to replace gas were wrong. The drop in gas from 2023 to 2024 is real, but it also includes a change in the way @californiaiso.bsky.social tracks gas generation.

Transmission Congestion 101. This is the snapshot of the Entergy New Orleans load shed event. Look at the negative pricing (dark blue) just ~200 miles away from the $2,000/MWh (dark red) in Southern LA

A great visualization of how the @californiaiso.bsky.social grid has changed dramatically. Here's the 2020 load shed event (Aug 15-16 - left) compared to the same days 4 years later. Look at how much solar and storage have changed the power mix - so much less imports and gas. @gridstatus.io

2/ This new accreditation regime was bad for solar and storage, storage got roughly what a gas CT did - 60%. Solar was a measly 13% - this is what happens when the risk moves to winter. Then PJM did an analysis assuming gas winterized. That shifts risk to summer - and behold, ELCC's shoot up

Affordability of electricity is crucial if we are going to use the grid to decarbonize other sectors. Distribution system capital deployment continues to outstrip other sectors (generation, transmission). Not clear what we are getting for all those $$.

Great takeaway from Aurora and @douglewin.bsky.social modeling what would happen should TX pass this awful bill.
Killing clean energy will drive up prices, and likely more than than this, because more gas demand will also drive gas prices us (h/t to @robinsonmeyer.bsky.social for pointing this out)

🔌💡 #PJM published its final RRI list of "Queue Jumping" projects. Less batteries than the previous (now just 2.2 GW), and less gas upgrades (just 2 GW). 6 GW of new gas. Check out ~900 MW of new nuclear - that's Three Mile Island restart! Nearly 12GW of new resources online by 2030/31.

5/ Generation and Distribution are roughly equivalent at about 45% of the customer bill (each). Rooftop solar does not provide significant distribution deferral value. It can only defer the generation portion of the bill, but it receives full retail credit under NEM. This is the major issue with NEM

@californiaiso.bsky.social - has only 16 GW of utility scale solar online, almost 10 GW less than #ERCOT (but if you add rooftop back in, CA is probably close to TX?).
CA's record utility scale solar is ~19GW.
But Solar is 60% of load in CA - only 50% in TX.

This is such a great chart from @wilson-energy.bsky.social, @robgramlichdc.bsky.social and team. Let's remember where we came from so we can navigate the future. We have dealt with load growth before, and it's a good thing. Flat load wasn't great for customer bills.

#ERCOT has been running at 85% clean today: 75% wind and solar and 10% nuclear. You would have been laughed out of the room if you predicted this 10 years ago. But the smallest interconnection in North America is cranking away at 75% variable resources. Beautiful sight.
