Mid-Week Update

Good morning,


NOAA Forecast Images

Enjoy this what’s remaining of this week’s warm weather as next week looks like the kicking-off point of autumn for much of the West (particularly east of the Cascades and east of Southern California).  The coastal regions will cool down from where they stand today but should still sit slightly above normal.

Precipitation Forecast

The Northwest will get its share of precipitation this week before seeing the weather pattern trend back toward normal.  Northern California appears particularly dry compared to normal where we might expect some measurable precip.

LMP Spreads

The SP-NP day ahead spreads are showing a difference of just $2 at their peak each of the past several days.  SP-NP increased that difference to $3 on the 22nd but fell back to $2 by the 23rd.


Crude came off nearly $2.00 yesterday and is now $10 off from its high on the 3rd of this month.  Gas is moving the opposite direction after tacking on another $0.08 yesterday, reaching as high as $3.29 in the process.

West Term Gas Prices

Sumas isn’t showing signs of slowing down in either November or January as it’s reached $11.22 and $9.96 in each month respectively.  Both months have seen Sumas more than double in just the past week as the pipeline explosion shows a more lasting effect on the market.

Spot Gas

AECO dipped as low as $0.41 on the 19th before climbing back to $1.23 as of yesterday.  Sumas isn’t showing any signs of letting up in spot gas either, reaching $7.79 yesterday without many signs of letting up.

Mid-C Demand

Seattle gets a moderate increase over normal today with a high of 59, three degrees above average.  Daily lows show the largest variance, however, as nights as falling only to 50, five degrees above where they typically sit this time of year.

The mild weather isn’t showing up as mild loads as week-on-week demand appears slightly up at its peak (100 MW), and up 200 MW in the daily average.

NP 15 Demand

NP peak demand increased just over 200 MW yesterday and was up more than 300 MW week-on-week.  Overnight low demand increased 150 MW day-on-day.

San Jose’s is showing a high right on track for normal today, but we’ll see temps slowly creep up heading into the weekend where highs will eventually reach the 80’s by the 26th.

While San Jose gets highs in the low 80’s, Sacramento gets highs up to 86 by the 27th, a full 13 degrees above normal.

SP-15 Demand

SP peak demand jumped more than 240 MW at its peak yesterday and saw an even larger 900 MW week-on-week increase.  Light loads climbed another 500 MW from their low Monday/Tuesday night.

Watch for a high of 88 in Burbank on Thursday, a seven degree increase over normal.  Heat will linger in the high 80s through Saturday before falling back to normal to begin the following work-week.  The beginning of November is showing potential for cooler nights with temps make their first appearance in the 40’s.

PV Demand

Phoenix will make its return to above normal temps, albeit only slightly, by the 26th.  While temps peak a couple degrees above normal, there aren’t any 90-degree days on the horizon.  Keep an eye on falling temps in PV during the first week of November as well.

Nuke Status

PV2 remains in refuel mode at 0% while all other plants stay at 100%.

Gas Plant Noms

SP gas noms fell to 795,090 MCF, down from 1.1M MCF on the 18th.  WECC Interior is still in free-fall mode as well after settling at 889,831 MCF, the lowest point since May 14th, and down from 1.4M MCF at the end of September.


SP-15 solar followed up last week’s low generation with a peak of 6,278 MW by the 18th, but that fell to just 5,737 MW by the 21st.  Wind didn’t add much during peak hours, but managed close to 1,000 MW in the late evening hours.

Mid-C wind has fallen nearly flat since the 13th with a high of just 83 MW of generation since then.

ISO Gas Outages

ISO gas outages set a new recent high at 5,589 MW yesterday, up from 4,600 one week prior.

The highlighted plants show where much of the day-on-day gas outage increase originated.



PNW Reservoirs

Mica remains on course for new 10-year lows in reservoir elevation, just as it’s done since the end of July.  Contrast that to Arrow which is more than 10′ above most of the previous five years.

Snow Anomaly

Last week’s warm weather burned off what little snowpack there was in most of the West, though the Canadian Rockies managed to add on to its early season pack.

Snow Depth Summary

Grand Coulee and Chief Joseph added on a fraction of an inch while every other station sent their snow down the river.




The BPA-COI line originally showed the TTC increase set for the 19th, but it is now scheduled on the 2nd of November, and should lead to an eventual TTC of 4,800 MW.

NOB remains down for maintenance.




Have a wonderful day,
