WEST Strong winds and wildfires across California have necessitated power shutoffs for thousands of customers and made index prices quite volatile. More-over, approximately 18,000 MW of resources remain offline for planned mainte-nance. Any heat event during early November could drive Day-Ahead prices up. In the term market, prices in CAISO have reversed their upward trend and moved slightly down along with NYMEX. Forward prices have also fallen in the Pacific Northwest on word of increased natural gas capacity before winter begins.
ERCOT Term prices have been mostly flat to down throughout the curve as term heat rates and natural gas have been mixed. Real-time prices have also been low for most days this week, save October 26, when operators curtailed wind output because of weather threats from a front moving south into Texas which happened to bring cloud cover that also reduced solar output. Conse-quently, the real-time average is nearly $230 / MWh for the on-peak hours. In addition, the ORDC adder for the month is now over $4/MWh, well above the $3/MWh and $1 / MWh for October 2019 and October 2018, respectively.
EAST Prices have continued to pick up this week amid the colder weather but are generally still soft. The DART spread in ISO-NE is averaging only $11/MWh in the on-peak hours this week, although RT was as much as $60/MWh over DA yester-day, thanks to strong load over-performance cloud coverage that reduced be-hind-the-meter generation, and marginal wind and hydro production.
