a watch that has been cancelled, not an emergency http://www.ercot.com/services/comm/mkt_notices/opsmessages/2021/04 Apr 13 2021 19:22:55 CST Physical Responsive Capability < 2500 MW: ERCOT has cancelled the following notice: ERCOT is issuing a Watch due to Physical Responsive Capability being below 2500 MW. Watch Cancelled there was no supply shortage in day ahead market (not a generation capacity shortage) http://www.ercot.com/content/cdr/html/20210413_dam_spp day-ahead forecast peak was ~2800 MW lower than current-day forecast, as a result actual load exceeded current-day HSL (High Sustained Limit). The gap peaked 340MW at 4pm http://www.ercot.com/content/cdr/html/loadForecastVsActualPreviousDay.html https://imgur.com/a/6MW5qU4 (screenshot) ancillary services (10 minute responsive reserve service, 30 minute non-spin) were deployed to meet higher than forecast demand and worked as expected reserve never dropped under 2300MW which would have triggered an emergency (EEA-1) emergency response service (additional generation/load resources reserved for emergencies) wasn't deployed http://www.ercot.com/services/programs/load/eils
Pity, I can't access ERCOT's web site (I believe others had the same issue last time). They say I need to show a business reason why access should be granted. I can't be asked.
There appears to be some discrepancy between what ERCOT are publishing and what the media are sharing. Wouldn't be the first time.
But considering it's all over the place, no smoke without fire. Mark.
