| 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 | |

| The Western markets have grabbed the attention of many over the past few years as SoCal Gas's infrastructure seemed to be falling apart starting with Aliso Canyon and then moving to the pipelines themselves as a fire broke out around the Mojave compressor. The constrainted the North Zone of SoCal's system and as a result solidified SoCal Citygate as the gas hub that would get all the attention in the cash market as there were scenarios where the gas volume would not be enough to go around. When this occurred, SoCal Gas has tiered penalities on days when there were low OFO's (Operational Flow Order) on the system. Figure 1 | Socal Citygate Cash Prices This led to several days, early in the week, where SoCal Citygate would trade well over any other hub in the ... » read more | |

| Over the past few weeks, the Pacific Northwest gas system has been restricted in a way that the Jackson Prairie storage facility has not been able to pull gas out of the ground. In essence, it has not been able to help balance the system at a time Mother Nature has brought in colder weather to the region. Yesterday, Northwest Pipe sent out a notice stating the work is now completed and normal operations at Jackson Prairie will be in play starting on the 18th. Figure 1 | Northwest Pipeline Critical Notice - Jackson Prairie This will be another lever that will be accessible once the big wind generation uptick shifts back down and natural gas-fired power plants are needed to help balance the system. In fact, if you look at the Roosevelt Compressor flows in the figure ... » read more | |

| The weather forecasts have been adding HDDs to the 11-15 day forecast and that alone has prompted the November contract to move up roughly $0.15 since the open on Monday. This is a pretty big move all things considered. Figure 1 | HDD Accumulation broken down by Day Buckets ** WSI Data The increase we are talking about can be seen in the following graph as the blue line represents the most recent model run and compares it to last year on same day and what normal HDDs look like given the temperatures in the major city airports. Figure 2 | HDD Accumulation for Days 1 -15 The moment you slice throgh last year's numbers it is cold as the winter timeframe started out rather cold in 2018. We will continue to monitor the direction of the HDD totals by region as the ... » read more | |

| In gymnastics, a perfect score is a 10.0 and is reflective of an athlete doing everything technically correct along with have some major difficulty in the routine itself. The scoring is based on experienced judges who have a trained eye to look at the sub-items tied to the two categories mentioned. If you are watching a local event, college competition or the Olymics, it is a rare but beautiful occurance when you get to witness the athlete actual produce such a score. Figure 1 | The Perfect 10 in Gymnastics In the energy world, specifically the Liquified Natural Gas (LNG) sector, the perfect score level continues to rise with the new facilities going live over the years. It was a commonplace to have the perfect score be as low as 2-3 BCF/d when things first started only ... » read more | |

| This past January, ERCOT adopted a proposed set of changes from the Public Utility Commission of Texas. These changes, affecting the Operating Reserve Demand Curve adder (ORDC), were set to take place in the beginning of 2019 and the beginning of 2020. The first change was in effect this past summer and contributed to the sky-high prices in August. Now, at the end of the summer, it’s time to look ahead at the upcoming second change. The changes cause the ORDC to trigger more often and to have a higher value when triggered than previously. EGPS calculated the ORDC for the prices this past June-September using both the old method and the new method. The figure below shows an example day, July 30. Figure 1 | ORDC New vs Old Methodology Comparison In this figure, Historical LMP is the ... » read more | |

| The recent weather extremes over the last couple weeks have finally given way to moderate weather. In the Northeast, temperatures have shifted into a comfortable range calling few degree days onto the board. With weather across the country shifting into the mild shoulder season, demand for generation has declined. Facilities have begun dropping offline during this period of low demand in order to perform much needed maintenance in order to prepare for the upcoming winter. The PJM outage report exemplifies the increase over the autumn shoulder season. We can see that generation outages started picking up after the start of September and continued to grow moving deeper into the shoulder season. Outages picked up throughout October, but it appears that peak outages have not yet made their ... » read more | |
