Temps in the low 20's-30's in the South and renewables holding it down again today: Texas (ERCOT) - ~50% solar! v. ~30% gas, with batteries dispatching earlier at ~ 6GWs #energysky

Temps are going to be even lower tonight than last week in the South, getting down to 18F in Northern MS, where currently outages from ice last week are leaving over 60k people without power still with little more than blankets to keep them warm💔. #energysky

MISO - 10% solar before sunset, ~12% wind and climbing tonight SPP - ~30% wind and climbing tonight #energysky

Aside from the persistent outages in LA, MS and TN, things were mostly back to normal today on the grid, with another big showing from solar and storage in ERCOT (once again solar outperformed nat gas for a good chunk today), great wind and solar in MISO, and lower wind in SPP. #energysky

Tuesday, and outages still number close to half a million in TX, LA, MS and TN as temps start to thaw. Temps will plummet this weekend too however, and MISO has already declared a Capacity Advisory for this Friday in the North of the footprint. www.misoenergy.org/markets-and-... #energysky

Entergy LA and MS's system got really hard by Fern, as did TVA's. At this time I have not heard of loadshed in either territory so it seems likely that this is probably heavy distribution damage from ice loading. #energysky

In North Louisiana it's also proved fatal with 5 lost to the storm weather.com/news/weather...

Currently ERCOT is serving more load with solar than natural gas 25,207MW's of solar vs. 23,787MW's of gas The average price in ERCOT is currently ~$23 #energysky

With subzero temps as far south as Jefferson, MO, and freezing temps all the way down to NOLA, outages are still around 800k in the South. SWEPCO and Entergy maps show a lot of the same outages, likely from ice + sustained freezing temps. #energysky

LMP maps in SPP and MISO show price separation between the North and South. Both footprints show wind picking up, but also a lot of solar in MISO. SPP - ~10GW's MISO - 14.1GW wind, 9GWs solar #energysky

A lot of outages with the amount of ice loading throughout TX, LA, AR, MS, TN and already a lot of others in the Southeast. #energytwitter

Another bright spot is that wind is forecast to be up later this evening into tomorrow, and solar as well (almost double what it was today). Same deal in ERCOT (already starting to see the strain there though on the LMP map) #energysky

It's cold comfort for folks in MISO who are currently enduring brutal freezing temperatures without power, but currently LMP's are elevated, but capacity margins seem to be in a good spot, which means that there's no imminent threat of load shed at the moment. #energysky

Already seeing some outages in the South with Winter Storm Fern. Around 900k are without power currently. Simultaneously, TVA is importing about 2GW's from SOCO, while simultaneously exporting ~ 2GW's to MISO. #energytwitter

Right when things get heavy in ERCOT according to their forecast (h/t @conorwaldock.bsky.social). It'll be interesting to see how storage and solar perform in ERCOT tomorrow given the generous amount of capacity in their footprint. Also, will be interesting to see flow on the DC ties #energysky

Later this evening MISO will be implementing EEA1 Max Gen for MISO North. Currently, imports from PJM and SPP are doing a lot for the footprint with 5-7GW's of imports at peak from both over the last day / night. Now SPP is providing about 3.75GW's #energysky www.misoenergy.org/markets-and-...

As the sun sets in Central Timezone, here's a couple energy trends as precipitation is at a lull in Eastern TX and AR (where there's currently sleet and snowfall already), but building towards a second round later this evening. weather.com/storms/winte... #energysky

Wind is at 21% but declining in SPP, around 3% in MISO, and 14% in ERCOT. It looks like SPP is in a lull until it picks up bigtime around noon Monday #energysky

In MISO EEA2 has already been called, and the N/S constraint has flipped to importing ~1GW. Also, MISO is pulling from SPP as of about noon to the tune of ~2GW's. Meanwhile forced outages remain down at the moment, but the LMP map looks a bit irritable. #energysky
