ERCOT daily briefing
Issue of Nov 13 · generated 8:03 AM CTLatest
Bottom line
The late-evening surge did not repeat; South versus West now deserves attention from 5 PM until 8 PM CST. Tonight prices only a $2/MWh South premium after yesterday’s $18/MWh.
Hub Average averaged $56/MWh against $64 day-ahead from 8 PM until 11 PM Nov. 12, leaving the repeat late-surge case weaker.
South averaged $18/MWh above West from 5 PM until 8 PM Nov. 12, reversing a cleared $23/MWh discount and breaking West’s evening lead.
Tonight’s clearance puts South $2/MWh above West from 5 PM until 8 PM Nov. 13, with Hub Average priced at $40/MWh.
South averaging at or below West from 5 PM until 8 PM Nov. 13 would weaken the case for a new evening leader.

Both hubs beat their own day-ahead prices in the early-evening window: South by $57.99/MWh and West by $16.23/MWh. South outperformance, rather than West weakness, drove the reversal. Demand averaged 429 MW above forecast then, versus 456 MW during the quieter late-evening window.
West’s rolling Nov. 12 at 8 AM to Nov. 13 at 8 AM mean fell from $104.12 to $51.49/MWh, below its $60.14 seven-issue baseline but above its $37.14 30-issue baseline. South averaged $51.60/MWh across the same window—effectively level with West—so its clear leadership remains an evening observation, not an all-hours pattern.
Metis 1 Preview’s 6:55 AM CST middle forecast averages $32.11/MWh against $39.84 cleared for Nov. 13 from 5 PM until 8 PM. That softer central outlook accompanies the regional repricing; the more distinctive desk question is whether South retains its evening lead.
