| If you have been in the electricity sector for some time, there are several revolving concepts and topics that always seem to pop up for discussion and/or debate depending on the time of year or circumstances around a specific market. One of those topics is the 'Capacity Market' within each ISO and RTO sector across all of North America. At the end of the day, this hot topic serves as a foundation to what most would consider reliability to the power grid. As stated, each market acts a little differently depending on the governing body and policy makers tied to the specific electricity balancing authority. The discussion have takend several turns over the years with PJM being the pioneer over the years. While other ISO's have been formed since the inception of ... » read more | |

| If you have every been to Phoenix there is a good chance you have seen Camelback Mountain as it is within the spawling metropolis in the desert. If you were there for vacation some might have even stayed at the resort that sits at the bottom of the mountain while others just decided to hike up to the top to get a glimpse of the city and surrounding area. It is a gorgous view at any time of day but the early morning to me is the best time as the city is just waking up and it is not too hot. Figure 1 | Camelback Mountain - Phoenix, AZ The reason for this introduction theme for the newsletter is that it ties in with the camelback demand profile terminology used in the power sector when the morning and evening ramp net load is much higher than the middle of the day ... » read more | |

| There are certain times of the year in the Pacific Northwest that crabbing on the coast is worth the drive in October, November or December It is a time where you can get all bundled up in your rain gear or waterproof high water boots as you make the journey into the bays that are deemed the best crab fishing east of the Mississippi. Figure 1 | Oregon Crab On my way home from work yesterday, I was listening to the local sports radio show and that is when I learned of another type of 'crabbing' that took place in Oregon yesterday. Like any good radio show, they would lead into the capture of the discussion minutes before and then break for a commercial. The head person started out by saying there was some crabbing at the airport yesterday so the co-anchor thought there ... » read more | |

| SoCal Gas can finally start wiping the mud off its face. For the past four years the utility has been under fire due to a number of infrastructure issues that have plagued its system. The ruptures at the Aliso Canyon storage cavern and the 235-2 pipeline outside of Bakersfield forced the utility to cut back on system pressures. This safety measure put service reliability at risk. Now after years of public humiliation, the utility has turned the corner. Restoration has now been finished on several pipes in the north part of their system and they are starting to return pressures. Aliso Canyon has also been deemed safe to operate and should see increased use this winter as a source of in ground supply. The hard work and efforts by SoCal Gas employees to overcome these hurdles should garner ... » read more | |

| With the Pacific Northwest overnight lows dropping this week, all eyes will be on the power and natural gas markets as the former still is exposed to electric baseboard heating demand as well as other power resources such as space heaters to warm up the space. The latter is looking at restrictions at the T-South compressor that have been in play all month. The current flows out at the top of the system have been sitting around the 1.25 BCF/d mark in recent days with roughly .65 BCF/d making its way into the Pacific Northwest via the Sumas compressor (which connects the Westcoast and Northwest Pipelines). With moderate rescom demand this past week and ample power burns, this was still enough to not pull from Jackson Prairie as long as the .52 BCF still moved from the ... » read more | |

| Over the past year, the Pacific Northwest natural gas market has been on it's tippy-toes as the 36 inch Enbridge pipeline explosion rocked Shelley, BC last October. Since that time, the T-South compressor flows have been the focal point as it is the main artery to getting gas down to Vancouver, BC and ultimately into the Pacific Northwest via the Sumas Compressor. We track these flows in our BC to PNW Natural Gas Balance dashboard in a daily basis as it gives us a good proxy to where the pinch point have been, will be and what to expect as in the coming days. Figure 1 | BC to PNW Pipeline Balance Summary Over the past year, we have seen the Sumas gas hub cash market explode at times when there were not enough molecules to go around for rescom, industrial and power ... » read more | |

| The nuclear bailout plan in Ohio doesn’t appear to be going anywhere soon. It is the latest in a long line of nuclear subsidies that have kept uneconomic generation running throughout the East and Midwest. The rival group, Ohioans Against Corporate Bailouts (OACB), attempted to put the legislation on the 2020 ballot but was unable to obtain the necessary signatures. Figure 1 | Davis-Besse Nuclear Facility Outside Toledo While other plans also faced challenges, the Ohio bill was the most strongly opposed. Unlike other nuclear subsidies that have gone into effect recently, the bill that was passed in Ohio also includes a subsidy towards coal generation. The law was initially proposed under the guise of reducing carbon and increasing air quality. However, later amendments lumped coal ... » read more | |

| The Tuesday day-ahead CAISO heavy load auction print ripped up to $56.59 for SP15 as the power demand was something to be wreckoned with. When you throw in the fact that the AC and DC interies are derated and Mead flows flat-lined due to a constraint on the grid, the only option to balance the grid was to turn on in-state generation. With PGAE's system already flexing as much as it can between the midday and evening ramp, the solution was to turn on generation within SCE's territory. Figure 1 | CAISO Day-Ahead Heavy Load Scheduled Generation This is evident in the figure above as the top pane represents PGAE while the bottom two detail the scheduled day-ahead generation profile for SCE and SDGE respectively. If you look at the past two days (furthest to the right), you ... » read more | |

| Reliability concerns have caught up with the Alberta gas market this month. Now that we are on the cusp of the withdrawal season they are making a last ditch effort to shore up supply. From April through September, the NGTL system injected 52 BCF which took the cavern inventory to 256 BCF. That was an average of 9 BCF per month and left the total storage capacity at 59% full. In just the first 20 days of October they have been able to inject 19 BCF taking the inventory up to 275 BCF. That narrows the year on year storage deficit from 80 to 59 BCF. This does not cure all of Alberta's woes but it certainly helps the cause for a stable supply environment for the coming heating season.

| It is not quite $9,000 but the concept is the same within ERCOT as Saturday's day-ahead auction clear saw a spike during the middle of the day. This spike was due to the fact that the wind hourly profile was taking a nose dive while the power demand was at its peak for the day. The figure below has the 19th sticking out like a sore thumb as the light blue coloration at the bottom of the graph is the closest thing to 0 mw while the red line (power demand) shoots up. Figure 1 | ERCOT Net Load Display From a price perspective, the auction clear for the given hour in question spiked up to $124.70 in the North Zone whereas the previous day saw the same hour (17) settle in at $20.70. This is just another indication that every grid tied to the growing renewable known as ... » read more | |
