Summer in ERCOT gets most of the attention as the hot days stretch the system.  In such times, system operators see the operating reserves diminish to a point that the Operating Reserve Demand Curve (ORDC) escalator price is added to the energy component within each hour.  We are not to this point yet, but the recent hourly price/implied heat rate pattern is worth discussing. Looking at the graph below, the red line represents load, the blue area shows wind generation, and the teal area shows net load—that is, load minus zero marginal cost resources. The yellow dotted line shows the North Zone’s day-ahead implied heat rate, which is calculated by dividing the auction power price by the bilateral gas price.

Growing up in the Midwest and now living in the Norhwest for over 20 years wrestling has been in my blood since my childhood.  I never have competed at a high level but participated in matches as apart of my middle and high school physical education classes.  When I went off to college, the University of Minnesota wrestling team was decent as they recruited out of the state of Iowa and Washington.  Two of the big time programs at the time were the University of Iowa and Oregon State.  Everyone knew the former as the lore of Dan Gable was present and still is to this day while the latter entrenched itself as being one of the top teams in the country residing in Corvalis, OR.   Figure 1 | Dan Gable Lore If you have ever been to a wresting match or ... » read more

Over the past few days my wife and I have had the opportunity to spend more time with our kids as we have taken the necessary actions to do our part to supress the virus from being transmitted in any way, shape or form.  This means that the lost art of having dinner together and talking to each other has come to light along with walking the dog as a family.  If I stop to think about it a bit, these two items mentioned were a common theme during my childhood as there was no iphone to hold onto, no club sport that required driving to/from practices/matches three times a week and cable television was so primative that it took up hardly any time at all.   Figure 1 | Sitting at the Dinner Table Up until last week, the hustle and bustle of today's world came to a halt with ... » read more

In an effort to avoid spreading COVID19, the population is starting to seclude themselves. Schools are closed. Restaurants have shut down and workers are staying at home instead of coming to the office. This has a toll on our economy. There are estimates that the United States gross national product will shrink by 5% this quarter due to the quarantine efforts. This will have a big effect on the fuels consumption. Since the first of the month we are starting to see evidence of a slowdown in the natural gas metering. Running regressed LDC demand versus temperature there is up to a 10% shift down in the distributed demand. Figure 1 | TCO-Ohio LDC Demand versus Average Temperatures in Columbus Over in Italy, the stats are similar when it comes to the power demand destruction (anywhere ... » read more

Over the years, we have described the State of California's hydro system as a three storm system.  By this we mean that all it takes is three storms to create what would be considered a decent water year hence the slogan 'when it rains it pours'.  Three does not seem like a lot but if you look back in time, the evolution of the jet streams provided the state with drought-like conditions between 2012 and 2016 where it became so dry that engineers were describing how certain foundations to housing complexes were shifting and cracking.  It was not too long after that the weather changed and California saw one of its wettest seasons on record, which in turn helped refill the storage facilitiies.  In fact, for those of you who have been in the business for some ... » read more

It won’t be long before we’ll start looking to the summer season in various power markets to see how the supply demand balance is fairing. Just last week ERCOT published its Seasonal Assessment of Resource Adequacy (SARA) for Summer 2020. Table 1 shows ERCOT’s overall projected supply-demand balance picture for Summer 2020 along with comparable values from ERCOT’s final Summer 2019 assessment.  Table 1 shows major resource categories and planning reserve margin (PRM), which is the percent by which total resources exceed expected (1-in-2) peak demand.  The table shows that year on year, ERCOT has significantly improved its position.  ERCOT is experiencing only  modest retirements, an increase in “mothballed-but-available” units, the ... » read more

Being the team manager for my son's travel soccer team has been quite interesting over the years.  For example, in December of 2018, the team traveled to North Carolina for the first of two National League weekends where they had four matches on the schedule. As they finished playing the second match on Friday, the news broke that the league was cancelling the remaining two matches due to severe weahter moving into the region.  Since I did not travel on this trip, I had to stop what I was doing here in Portland, OR and get on the phone with the airline where I booked the block of 18 tickets to see what my options were to try and get out before the storm hit.  I had no luck at the time as the only option would have been to potentially drive from Raleigh, NC to New ... » read more

The chaos in the market this week has been well documented as the stock market saw its biggest drop since the housing crash over a decade ago, crude prices moved down almost $10.00 prior to the US markets opening up Monday morning and the natural gas space started to follow suite as the prompt month was down $0.08 prior to the open.  All of this downward movement was tied to the COVID 19 virus spreading across the world with countries like China and Italy in full lockdown mode as the number of cases grew.  In the US, the weekend was filled with news tied to the COVID 19 virus being detected amongst many within cities across the country.  This has led ompanies and state agencies to implement tele-communting procedures, travel bans and actual closures to minimizing the ... » read more

As part of the ongoing build out of the Nova Gas Transmission system in Alberta, TC Energy is expanding their pipeline footprint into the United States. The West Side Expansion is a 1 billion dollar investment to bring more Foothills gas production into British Columbia and the Pacific Northwest. But this is only feasible if downstream paths increase their capacity to take the additional gas. Appropriately, they have announced a 335 million dollar expansion of the Gas Transmission Northwest Pipeline which connects down to the PG&E system in Northern California. The new capacity would add another .25 BCF to the existing 2.8 BCF of deliverability onto the Kingsgate compressor station at the Canadian Border.

This blog reports on a paper co-authored by REsurety and Energy GPS titled The “P99 Hedge” That Wasn’t which was originally released in the spring of 2018 and was updated on March 3rd 2020. A copy of the original paper and the update can be found here: https://documentcloud.adobe.com/link/track?uri=urn:aaid:scds:US:40414cea-833b-4b21-99ec-8aba42571c65 For a number of years, ERCOT generation owners, retail electric providers, and traders have anxiously awaited the hot summer months to see if spot prices would finally experience sustained price spikes up into the thousands of dollars per MWh. They rarely did. Forward contracts for on peak August 2018 and then August 2019 deliveries ranged in value from $75 per MWh to more than $200 per MWh in advance of the delivery month. » read more
