Reposted by Andy Kowalczykathada.bsky.social @athada.bsky.social · 07/02/2026Big jump in the record solar production for MISO today. Hit 20% of total demand, besting wind. I've not seen it surpass fossil gas yet, but I'm betting that happens this spring. #EnergySky 032
Reposted by Andy KowalczykJohn Hanger @jrfhanger.bsky.social · 03/02/2026US utility-scale wind & solar is on track to reach 430 GW by November 2028. That's up 28%! Small solar is ~58 GW now and will add another ~21 GW by 11/2028. So, total W&S capacity will be ~509 GW by 11/2028! Petrostate politicos are losing the war on W&S. cms.ferc.gov/media/energy... #energysky 3215
Andy Kowalczyk @ascottkoala.bsky.social · 31/01/2026A silver lining is that at least it appears we won't have any forced outages in MISO. Boy howdy the gap between wind / solar with only ~600MW's of storage is rough to look at in MISO. #energysky 001
Andy Kowalczyk @ascottkoala.bsky.social · 31/01/2026Temps 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 101
Andy Kowalczyk @ascottkoala.bsky.social · 31/01/2026Interesting intertie stuff: ERCOT: Welsh Eastern DC Tie into NW LA has been dispatching at max (600MW's) into SPP all day. MISO: About 5GWs - SPP 900MWs at peak - Manitoba Hydro - SOCO ~1GW all day - PJM looks like they get wind, but not solar from MISO looking at the shape #energysky 100
Andy Kowalczyk @ascottkoala.bsky.social · 31/01/2026MISO - 10% solar before sunset, ~12% wind and climbing tonight SPP - ~30% wind and climbing tonight #energysky 100
Andy Kowalczyk @ascottkoala.bsky.social · 31/01/2026Temps 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 1148
Andy Kowalczyk @ascottkoala.bsky.social · 27/01/2026However, LMP's show constraints related to getting this power where it needs to go, and in MISO, price separation continues to show there's a MISO South market and a MISO North Market, but not really a MISO Market... #energysky 001
Andy Kowalczyk @ascottkoala.bsky.social · 27/01/2026Aside 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 102
Andy Kowalczyk @ascottkoala.bsky.social · 27/01/2026It could be that since the May 25th loadshed event, ops is prioritizing MISO South to a greater extent and reducing imports from MISO South - but this is speculation #energysky Interesting flows going south over the last day in any case. ~1k to SOCO from MISO ~600 to SPP from ERCOT (to N LA) 000
Andy Kowalczyk @ascottkoala.bsky.social · 27/01/2026Tuesday, 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 210

Andy Kowalczyk @ascottkoala.bsky.social · 26/01/2026Entergy 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 110

Andy Kowalczyk @ascottkoala.bsky.social · 26/01/2026ERCOT is putting up some interesting numbers on storage! Earlier Today: 7.5GWs! around 8am Yesterday: just shy of 2GW dispatch in the AM, and about 1.5 in the evening and charging overnight Big numbers for solar and wind later today. Currently solar @17,812 MW(24.0% of the mix) #energysky 021
Andy Kowalczyk @ascottkoala.bsky.social · 26/01/2026LMP 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 101
Andy Kowalczyk @ascottkoala.bsky.social · 26/01/2026TVA is doing what they to restore power, but report that there have been issues with ice loading on transmission. Otherwise they are saying that the system is functioning well. www.youtube.com/watch?v=mqA-... #energyskyyoutube.comTVA crews working to restore power across the stateYouTube video by WKRN News 2 101
Andy Kowalczyk @ascottkoala.bsky.social · 26/01/2026With 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 111
Andy Kowalczyk @ascottkoala.bsky.social · 26/01/2026MISO is only pulling about 1GW total across all interties, mostly with PJM currently. ERCOT's DC ties are pulling about 500MW's from the east, mostly from SPP after doing the opposite while the sun was out (duck-curve related?) #energysky 020
Andy Kowalczyk @ascottkoala.bsky.social · 26/01/2026Another 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 100
Andy Kowalczyk @ascottkoala.bsky.social · 26/01/2026However, as mentioned MISO will be implementing EEA1 from 9pmCT-midnight. 100
Andy Kowalczyk @ascottkoala.bsky.social · 26/01/2026It'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 110

Andy Kowalczyk @ascottkoala.bsky.social · 25/01/2026Right 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 210
Andy Kowalczyk @ascottkoala.bsky.social · 25/01/2026Wind and solar are forecast to show up big in ERCOT tomorrow as well as in MISO, with a healthy serving of wind around 8amCT in SPP as well. #energysky 101
Andy Kowalczyk @ascottkoala.bsky.social · 25/01/2026Later 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-... 100
Andy Kowalczyk @ascottkoala.bsky.social · 25/01/2026Already 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 202
Andy Kowalczyk @ascottkoala.bsky.social · 25/01/2026I remember hearing at recent MISO Board Meetings that due to drought conditions Manitoba Hydro was also set to be in a pinch - hoping for the best for our neighbors to the North! #energytwitter 011
Andy Kowalczyk @ascottkoala.bsky.social · 24/01/2026MISO will be one to watch tonight and all three of these footprints might be in white knuckle mode the next 48 hours #energysky 000
Andy Kowalczyk @ascottkoala.bsky.social · 24/01/2026Wind 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 101
Andy Kowalczyk @ascottkoala.bsky.social · 24/01/2026Clearly ALOT of congestion in SPP and South Texas - perhaps a lot of wind stuck in OK, North TX and KS. Gee those ITP projects can't get here fast enough can they? #energysky 100
Andy Kowalczyk @ascottkoala.bsky.social · 24/01/2026In 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 101
