Mid-Week Update

Good morning,


NOAA Forecast Images

The Rockies are doing their best to hold off a dramatic cool front that’s enveloped 2/3 of the country, but if the second-half of the 2-week forecast holds true, we should expect most of the WECC to stay in the normal range at the coolest.  Southern California is on an island with its warmer than normal forecast in both weeks.

Precipitation Forecast

Cool, warm, it doesn’t matter when it comes to precip as the forecast is calling for a dearth of rain, at least in terms of percent of average, for the entirety of the WECC.

LMP Spreads

The SP-PV day ahead spreads peaked at a massive $27 on the 5th but narrowed to $4 on the 6th.  SP-NP showed a difference of $4 and $2 on those same days, respectively.


Crude finished the day down $0.80 after rising as much as $0.35 by midday.  Gas was up $0.02 in what turned out to be a volatile day as well as prices had climbed more than $0.05 by late afternoon.

West Term Gas Prices

December Sumas is staying on its erratic and mostly unpredictable course following a $1.25 rise over the past three days.  That comes off the back of what had been the lowest price since the early stage of the Enbridge explosion at $7.16.  April and July appear stable for Sumas, though July is beginning to rise for Socal Citygate.

Gas Storage

Jackson Prairie made a small climb to 9 MMCF on the 3rd, the first positive storage number in several weeks, but has since fallen back below 0.

Spot Gas

AECO has more than quadrupled over the past three days and now sits at $2.81, compare that to $0.57 from Saturday.  Sumas more than doubled overnight after settling at $9.67 compared to $4.08 the day before.

Mid-C Demand

Seattle is projecting overnight lows tonight at eight degrees below normal, and tomorrow high to come up seven degrees below average.  The following two days appear to climb back to normal before a very slight warm spell approaches.

Peak loads in Mid-C made a moderate increase of 600 MW yesterday, but the main story was in overnight loads as the low jumped 1,200 MW day-on-day.

NP 15 Demand

NP peak demand was down sharply yesterday but managed a small 250 MW increase in overnight loads.  Week-on-week peak demand fell 400 MW yesterday as well.

No doubt Northern California is exempt from the Eastern-half’s sudden chill as San Jose projects highs above normal throughout the remainder of the two-week forecast.  Today calls for a high of 76, eight above normal, while lows should maintain a 50-degree floor.  Sacramento shows much of the same with daily highs in the mid-70s to round out the week.

SP-15 Demand

SP peak demand fell day-on-day as well as loads came up 700 MW short of Monday.  Off-peak demand increased 240 MW at its low day-on-day.

Look for Burbank to get progressively warmer leading into the weekend, eventually welcoming a high of 84 by the 12th, as impressive 12 degrees above normal.  We aren’t seeing as much anomaly in daily lows, however, as most days hug the average line tightly.

PV Demand

Phoenix is projecting very mild temps, some even below normal albeit remaining in the mid-70s.  Just two days over the next 14 are projected in the 80’s.

Vegas is even cooler as the 8th and 9th mark highs in the 60s.

Nuke Status

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

Gas Plant Noms

SP gas noms jumped 70,000 MCF yesterday but remain at their second-lowest point since mid-October.  Mid-C climbed another 58,000 MCF to reach 408,000 MCF, the highest point since October 23rd.


SP-15 solar increased 900 MW day-on-day Monday following Sunday’s sub-5,000 MW output.  Wind averaged more than 1,500 MW over the 4th and 5th, adding to the overall renewable total.

Mid-C wind peaked at 2,700 MW on the 2nd but has seen a sharp decline day-on-day ever since, though it remains well above 1,000 MW in nearly all hours.

ISO Gas Outages

ISO gas outages fell just under 500 MW since the 4th and now sit at 5,354 MW, down 900 MW since the 30th of October.



PNW Reservoirs

Albeni Falls remains a foot under average and continues to set a new 10-year low for elevation on this date.

Snow Anomaly

Cooler weather and measurable precipitation led to a decent amount of snow in the Rockies and Washington’s Cascades.  BC added to its early-season snowpack as well, and Montana shows much of its stations above the 110% mark in early results.

Snow Depth Summary

Clark Fork, Upper Snake, Kootenai, and Clearwater all generated more than an inch in snow build over last week, though Kootenai saw most of that over just the last three days.




Note the first signs of NOBs return, currently scheduled for the first hour on the 19th.

Very subtle changes to the COI line as there are a scattered few hours on the 13th and 14th with week-on-week differences, otherwise everything is moving forward as shown last week.




Have a wonderful day,
