| The SPP market continues to deal with its fair share of wind generation, especially when compared to the overall demand across the North and South region. As far back as October, the system operators have resorted to renewable curtailments to balance their grid often. The block of hours that have less exposure to such curtailments are those associated to high demand which in the winter usually is tied to colder weather moving through the central vertical third of North America. In recent weeks, the SPP grid has also seen the two nuclear units return to full capacity as their respective refueling maintenance period has ended, adding roughly 2.0 GWa of baseload energy that falls in the ‘must run’ category. Over the long holiday weekend, SPP’s ... » read more | |

| Over the past decade PG&E has made a number of changes to reduce operating costs on their gas distribution system in order to fund the growing costs attributed to renewables transition as well as the most recent bankruptcy settlement. Some of those decisions included the retirement of two gas storage fields at Los Medanos and Pleasant Valley as well as the reclassification of 51 BCF of working gas over to base gas. The retirements and reclassifications were done in the aftermath of the Aliso Canyon rupture in Southern California which has forced more reliance on import pipeline capacity to meet the natural gas demand needs in Northern California. The decision to remove of gas storage capacity has now come home to roost as PG&E has not only entered into the withdrawal ... » read more | |

| The month of November flown by rather quickly as December 2022 is right around the corner. If you lived in Western Canada or the Pacific Northwest portion of the Lower 48, you have dealing with well-below normal temperatures throughout and the last few days of November are no different. In fact, we see the start of December to look like that of November as Mother Nature is continuing the trend of brisk overnight lows across both regions and extending into the Rockies and Northern California. This is going to keep the balancing act around molecules and megawatts quite interesting as the systems that once delivered power to other regions will be pricing themselves to keep the units at home.

| Last Friday, the EPA announced a decision to deny General James M Gavin Power Plant an extension to continue disposing waste in an unlined coal ash pond. Located in Ohio and serving PJM, the plant is the ninth-largest coal plant in the country with a capacity of 2,680 MW. The decision comes from EPA’s Coal Combustion Residuals rule which aims to protect groundwater from contaminants, such as mercury and arsenic. Plants were given until April 11, 2021 to cease waste disposal in these ponds or upgrade their management by using lined ponds, closing unlined ponds, and monitoring groundwater contamination. Over 50 plants filed for an extension and the Gavin decision is one in a string of decisions from the EPA over the last several months.

| For the past months there has been plenty of talk about how natural gas prices have surpassed the price of ethane, a natural gas liquid, in MMbtu terms. While there is no perfect substitutability between the two fuels there are scenarios where natural gas can be switched out as a feedstock in industrial applications in lieu of ethane. On the supply side it becomes more profitable for NGL fractionators to bleed ethane into the natural gas pipeline stream when the economic incentive exists like it does today. The ability for ethane to be supplemented in the storage balancing puts ethane on the margin in those areas where the fractionators enjoy the optionality of the natural gas stream.

| The holiday season is upon us as the first of many get togethers with family and friends will be this Thursday and go through the weekend. From the looks of things, the weather should cooperate across the country as the coldest days look to be behind us. For those who live in Upstate New York, the warmer weather cannot come soon enough as the weekend snowstorm was one for the ages. Turning to the South Central region, the colder days will be met with some warmth during the day along with an increase in the wind generation once again. Figure 1 | SPP 12x24 Wind Profile The figure above illustrates just how impressive the wind generation has been within SPP this November compared to the past couple of months and years. The monthly shape represents the average ... » read more | |

| The flu season is upon us as many have been rushing to get their seasonal shots as the strands seem to be more potent in 2022-2023 than in years past. The flu can be something that disrupts your routine for days as a congested chest and cold symptoms turn into a fever and the chills. Once all this is present and the over-the-counter medication does not relieve the pain, Zoom Care or an appointment with your doctor is in order to get a more potent prescription. In the energy space, the CAISO system operator has been playing doctor when it comes to the growing pains brought about by the growth in the renewable technologies. For example, CAISO has basically fast-tracked the battery technology over the past two years as the rising need for flexibility during the evening ... » read more | |

| Each month as part of our Newsletter Platinum Plus package, we publish a report on the developments relevant to the renewable space over the previous month across the country, touching on CAISO and the West, ERCOT, SPP, and PJM in particular. In our latest report, “October 2022 – Where the Wind Blows”, we discussed the explosion in wind production that set off during the last week of October but has extended through the first half of November as well. The impressive wind performance was present in California but has been most eye-popping in the Southwest in ERCOT as well as to the North in SPP. Figure 1 | SPP 7-Day Average Net Load Focusing on SPP, the winds have been strong enough to push net load down to the lowest levels seen in the past three ... » read more | |

| The holiday season is almost upon us. Turkeys, stuffing, and mashed potatoes will be laid out on tables across the country next week. And many will soon start shopping for presents to be wrapped up and placed under a brightly decorated tree come Christmas morning. In the energy business, this holiday season brings the wrapping up of the nuclear outage season and the gift is having baseload, low-carbon energy back on the grid. With temperatures falling and heating demand rising, this will be a welcome return for many regions. This past spring, we at EnergyGPS revamped our nuclear outage forecast. The figure below is delivered daily to subscribers to our NRC nuclear report. Email [email protected] if you’re interested in receiving these to your inbox. The figure shows historic ... » read more | |

| The looming question over the head of the natural gas market over the past months is about the return of the Freeport LNG facility. And it should be as the terminal will consume up to 2 BCF per day of Gulf Coast natural gas when the go ahead is given to restart operations. In the meantime the molecules dedicated to tanker loadings and exports are being backed into the Gulf storage balancing. Since the rupture happened on June 8 the rejection of 2 BCF per day of feed gas has been the single biggest contributor to the rebound in EIA South Central storage inventory. Since the event occurred the storage inventory has climbed from .8 to 1.2 BCF per day. Absent the shut down the injections would have missed some 320 BCF of volume leaving the regions inventory at only .9 TCF. That would be a ... » read more | |
