Mid-Week Update

Good morning,


NOAA Forecast Images

Warmer than normal temps should peak this week, but there are strong signs that they will linger into next week as well, albeit a bit more subdued.  What can otherwise be a cold area in mid-October, Eastern Washington and the Rockies of Northern Idaho and Western Montana look particularly warm this week.

Precipitation Forecast

Look for a wet Northwest and a dry Southwest over the next two weeks.  Temps are still too warm to do much to snowpack in most elevations.

LMP Spreads

The SP-NP day ahead spreads hit their peak with $19 of difference on the 16th at 12:00.  We’ve seen congestion from 9:00 to 17:00 every day this week.  Peak loads, on the other hand, have typically been within $1 of each other.


Crude was off $0.54 yesterday after falling almost immediately after opening and settled at $70.91.  Gas moved the opposite direction with a $0.04 raise to $3.35.

West Term Gas Prices

November Sumas is still shooting up and has now passed SoCal Citygate ($4.85) as yesterday settled at $5.23.  January has increased a more modest $0.90 since the pipe explosion while April and July appear unaffected.

Spot Gas

AECO posted a $0.58 decrease day-on-day after falling to $0.63, nearly equal to a $1.90 decrease in just a week.  Sumas has fallen $0.50 over the past two days and $0.40 day-on-day.

AECO and Sumas shot off in opposite directions since the BC pipe explosion.

Mid-C Demand

Seattle gets a massive 15-degrees above normal high today at 73, and warm weather should persist through the rest of the two weeks as each day projects above-normal highs.  Portland shows highs in the 70’s through the 21st as well, and a high of 75 today.

Northwest loads fell 600 MW at their peak yesterday as temps climbed closer to a neutral degree-day level.  Yesterday also represented a 1,050 MW increase in loads week-on-week.

NP 15 Demand

NP peak demand fell just under 16 MW day-on-day yesterday, essentially unchanged, but was down more than 500 MW week-on-week.  Light loads showed a 350 MW increase day-on-day.

San Jose’s forecast is filled with daily highs several degrees above normal.  Today checks in at 78, four above normal, and eventually climbs to 80 by the 19th, six degrees above normal.

Sacramento is forecasting predictably warmer as every day over the next two weeks shows a high of at least 80 degrees, and a peak of 85 on the 19th.

SP-15 Demand

SP peak demand jumped more than 230 MW at its peak yesterday compared to Monday, but still fell 600 MW short in the week-on-week comparison.  Light loads climbed another 150 MW on their low late last night.

Burbank gets its share of warm weather this week as well.  Temps will reach into the high 80s through the 21st before temporarily dropping three degrees from normal on both the 22nd and 23rd.

PV Demand

Phoenix falls well below normal for each of the next three days, especially today with a high of just 77 (11 degrees below normal).  Just three days over the next 14 are projected above normal with many falling more than five degrees from average.

Nuke Status

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

Gas Plant Noms

SP gas noms increased 230,000 MCF over the past ten days and now sits at the second-highest level of the month.  Mid-C dropped to 296,000 MCF on the 14th coming off the explosion where it was at 585,000 MCF, but now has risen to 428,000 MCF.


SP-15 solar topped out at just 5,400 MW on Monday, an 1,100 MW decrease week-on-week.  Wind added 1,500 MW to make up for some of the lost solar production, but overall renewables remained down.

Mid-C wind has been quiet since the 12th’s 1,582 MW production as the previous two days failed to reach even 200 MW.

ISO Gas Outages

ISO gas outages began their climb on the 30th of September and have maintained that level for the most part ever since.  Outages totaled 4,656 MW yesterday, a 600 MW increase day-on-day.

The highlighted plants show the source of the day-on-day gas outage increase.



PNW Reservoirs

Mica shows the largest year-on-year differential as the reservoir sits 10 feet lower than it did on the same date last year.

Snow Anomaly

It’s a bit too early to look at anomaly percentages, but we can at least start to peek at our snow map.  A quick look shows that the majority of snowpack is taking hold in the Rockies while the Cascades and Sierra Nevada remain mostly bare.

Snow Depth Summary

Only a handful of basins are showing a greater than 1/4″ increase of snow depth week-on-week.




The BPA-COI line will increase its TTC from 2,000 MW to 3,500 MW by the 19th.




Have a wonderful day,
