While North America has got off to a slow start to winter it is about to change in the coming days particularly north of the Canadian Border. Driven by extreme cold coming out of the Arctic, Western Canada is about to see some of the coldest temperatures on record for a December. From tomorrow through the end of the year average temperatures are going to fall to well below zero with departures 20+ degrees below normal. This is in stark contrast to what is happening in the Lower 48. Most of the Gulf Coast continues to see record warmth with daytime highs near 80 degrees.As of right now most of this record cold weather is confined to Canada with some impact in the Pacific Northwest. And as of this morning the ridge that is keeping this formation north of the border is remaining intact so ... » read more

A white holiday season is in the cards for many regions across the northern part of North America as this weekend delivered the goods.  For example, on Saturday morning in rural WI you would have been snowed in as Mother Nature delivered 14 inches of the white stuff.  It is at that time, you hope the wood pile inside your attached garage is stacked so you do not have to go outside until the County snowplowing crew can get to your rural driveway to plow a path for your vehicle to get out if need be. Figure 1 | Recent Wisconsin Snowfall The recent event did not seem very likely given the fact that the start of the winter season was quite moderate when it came to delivering colder weather across key demand regions in the Lower 48. As a result of such conditions, the overall ... » read more

By Tim Belden For many years Energy GPS has been supporting corporate buyers of renewable energy to navigate the often tumultuous and sometimes frothy waters of wholesale electricity markets. In the 2015 to 2018 time period, a chunk of this work entailed explaining to corporate off-takers why their VPPA settlements were negative and re-calibrating expectations for the future. Of course, early deals were done back in the days of jacked-up forward curves and buyers who probably didn’t ask the hard questions. In particular, the forward curves underpinning their expectations were often based on much higher natural gas prices (not to mention renewable “capture rates” or “shape values” that were too high). As natural gas prices languished for many years, the ... » read more

SPP seems to be at the forefront of having too much renewable generation or the simple fact that their transmission infrastructure is not up to par given the influx of wind output over the years.  At the end of the day, either component results in the simple fact that renewable wind curtailments exist and in recent months has an upward trajectory that is a bit concerning. Figure 1 | SPP Curtailments – Year on Year Comparison This is evident in the graph above as it represents the manual and re-dispatch curtailments within SPP. Since SPP is tied to mostly wind generation, the graph is represented of the renewable resource as the main component.  The illustration is simple, it is a comparison of the curtailments year on year starting in 2018.  We reset the volume ... » read more

While most North American gas price hubs are still waiting for weather to drive some pricing action, western markets are getting winter underway.  The Sumas market in the Pacific Northwest, in particular, has been ramping up in recent days and could see some more gains ahead.  The brutal flooding thrashing British Columbia has created yet another restriction of gas flows southward into Sumas at the same time that Sumas demand is rising.  The spot cash prices there have risen by about 20% from the start of the month on the confluence of some seasonal cold plus upstream supply constraints and intra-market power fundamentals. Figure 1 | Sumas spot cash fixed and basis prices, gas winter-to-date. Over the past couple of weeks, seasonal cold has finally moved into the Pacific ... » read more

The story for the first six weeks of the winter natural gas withdrawal season has been the lack of heating load across the continent. The month of November averaged only 27 BCF per day which was 2 BCF per day below estimates. The first half of December is expected to average only 31 BCF per day which is 5.5 BCF per day below estimates. The concern was not only the lack of actual space heating demand but the impression from the weather models that the pattern would have staying power through the end of the month. Without December ResCom demand the storage complex would have ample supply through the end of winter. Since the last week of October the Q1 has fallen from $6.06 to only $3.60.

The Pacific Northwest has gone from moderate temperatures last week to that of a nice chill up and down I-5, specifically Seattle and Portland.  The fluctuation in temperatures will continue this week with the next day or two holding just above the freezing level when it comes to the overnight temperatures whereas the latter part of the week is calling for the potential of lower level snow due to some areas down into the upper 20’s with daytime highs in the lower 40’s.  This will be the first real cold temperature pattern of the winter, which has started out with the atmospheric river system wreaking havoc on the area just north of Seattle and in the lower southwest corner of British Columbia.

The duck curve in CAISO is a well-talked-about phenomenon: during the middle of the day, as solar comes online, it makes a dent in the net load (net load is defined as load minus wind and solar), and the size of the dent has grown over time as more solar has been installed. Plotting several years’ worth of net load data on a single chart results in a distinctive duck shape: Figure 1: CAISO average net load by year from 2013-2020. Credit CAISO, via This has always been a phenomenon unique to the CAISO. However, ERCOT has built out solar at a rapid pace over this past year, and the same sort of shape has begun to show up occasionally in ERCOT net loads.

Over the past few days, ERCOT has delivered some price spikes come the real-time market’s morning and evening ramp block of hours.  You can clearly see from the graph below that we are not talking near capacity levels by any means but the simple fact that both intraday real-time periods mentioned are outpacing that of the day-ahead is noteworthy. Figure 1 | ERCOT North Real-Time vs. Day-Ahead Price and Power Demand Profiles – Hourly The top pane represents the North zone hourly day-ahead (blue) vs. that of the real-time hourly settles (orange).  You can see that the jump up in price started to show up during the evening ramp on the 28th and escalated on the 29th only to fall back in line with the day-ahead over the past couple of days with both markets giving the ... » read more

“I can guarantee the lights will stay on…” Texas Governor Greg Abbott made that statement to an Austin radio station last week.  The comment was in response to a report issued by FERC and the North American Electric Reliability Council (NERC) warning that ERCOT is still at risk of substantial blackouts this winter should intense winter conditions return. Figure 1 | Texas Governor Abbott, who recently issued a guarantee there will not be power outages this winter due to cold-weather events as seen last winter and previous winters.  Image via Houston Chronicle. The crux of the FERC/NERC report was that a hefty chunk of last February’s power and gas system outages could have been avoided if generation owners and pipeliners had implemented previous ... » read more
