| Yesterday morning, Alberta’s pool price went to the $1000/MWh cap and AESO declared an Energy Emergency Alert Level 3. It occurred in hour ending 8 as Albertans were waking to chilly temperatures as overnight lows had dropped below the freezing mark. Demand was on the rise at 10.3 GW, below the eventual morning peak and below the 10.7 GW peak from the night before. The region’s growing solar resources had only 150 MW to offer to the grid in the cold autumn morning. The solar profile narrows during this time of year. However, the biggest gap came from the region’s other renewable resource: wind. On average this October, wind generation at HE 8 has been around 1.6 GW. Yesterday in HE 8, wind generation was below 0.4 GW. In the early morning hours, it was even lower. The ... » read more | |

| As October draws to a close and autumn deepens, cooler temperatures begin to make their presence felt, signaling the seasonal shift from mild days to the crisp chill of fall. This change marks a turning point in the natural gas market, where heating demand begins to rise once again, reversing the summer lull. The shift in weather not only impacts demand but also marks the end of the storage injection season, transitioning into the crucial period of withdrawals from underground caverns. This dynamic sets the stage for the upcoming winter, shaping market strategies and price movements in the weeks ahead. Taking a step back, the summer of 2024 began with Alberta's natural gas storage caverns well-stocked, following a mild winter with minimal withdrawals. This surplus laid a solid foundation ... » read more | |

| Halloween is just around the corner, as signaled by the giant skeletons appearing on front lawns and bulk bags of candy crowding grocery store shelves. Everyone knows we are close to the event of the season, in terms of candy consumption. But now, candy storage is at a high, and tricker treaters don’t even have their costumes together yet. Trade out candy for natural gas, and Halloween for Winter and you have the situation in West gas markets. Everyone knows the cold is near, but that does not do much good when most of California can go to dinner in a T-Shirt. The massive quantities of gas sitting in storage caverns mean that there’s no critical need to inject gas, just as there’s no critical need to run to the convenience store for a Snickers.

| There are many ways to describe a set of numbers: max, min, average, sum, median, mode, variance, standard deviation, etc. Each tells us something but doesn’t always describe the whole picture. As we look at wind generation in ERCOT over the next few days, we focus on one metric: the daily average (flat). A substantial amount of wind is in the forecast for ERCOT for the end of this week, with Friday October 18th expecting a daily average that is well above the norm for this time of year. In Figure 1 below, taken on 10/17/24 from the EPGS ERCOT Real-Time Dashboard, the dark blue line shows actual hourly wind generation, and the light blue line is the forecast. Shown as a grey horizontal line, a daily average wind generation of 23.0 GW ... » read more | |

| Last week saw the final piece of information made available to look at how the renewable scene played out in ERCOT over the past summer. Always on a delay to be posted all at once for the prior month, last week ERCOT’s solar and wind curtailment numbers for September were posted to round out the Q3 period. This is one of the markets focused on in our latest Renewable Quarterly report, “Q3 2024: Solar Wows for the Summer”. Fears were sparked heading into the summer based on the expectation for structural load growth to leave ERCOT facing new highs in summer demand. This was the case last summer, when the structural changes tied to new data centers and cryptocurrency facilities combined with a warm August to push prices to their highest levels seen ... » read more | |

| Last week was big for the largest battery fleets in the country. Both the CAISO and ERCOT battery fleets reached new peak dispatch levels last Monday, October 7th. For CAISO, the new maximum output is 8.4 GW while ERCOT’s fleet development remains a few years behind. The ERCOT fleet peaked at 4.0 GW. For both, the new records just barely surpassed the old ones, moving up around 100 MW. The figure below displays each fleet’s running maximum output for 2024. This time of year, dispatch growth tends to be more stagnant while the spring and summer typically offer more capacity growth and times of scarcity that lead to broken dispatch records. In our latest battery report, titled ‘New Peaks for Battery Fleets’, we checked in on the growing capacity levels for both ... » read more | |

| Typically, the month of October is the time when the weather changes, with the transition from summer conditions to autumn cooler temperatures. However, it has not been the case across the Southwest Power Pool region as Mother nature delivered some heat during the first half of this month (October). We see that in the matrix below which displays the cooling degree days (CDDs), by showing the difference from the normal conditions, with the red color indicating much above normal conditions and purple showing the opposite. Except for the two days of October where we observed below normal conditions, the month of October has been unusually warm. Figure 1 | South SPP CDD – Departure from Normal As a result, the energy demand has been strong this month, much higher than the levels ... » read more | |

| October arrived with a bang to the West’s natural gas markets. In recent blogs we have already covered the shifts in energy market fundamentals which drove up October pricing, where unseasonal heat overlapped with the start of outage season. Last week upped the ante as that tightness translated to price spikes. The critical factor was congestion, as California’s north became an island, unable to draw in MWs from surrounding regions while Sacramento scorched. Figure 1 | CAISO Day Ahead Transmission Market by Region The table above shows the regional LMP and cost of congestion across CAISO regions. The standout feature is the elevated prices in NP15/PGAE compared to their southern neighbors. California does not publish transmission data from their critical path 15 and path 26 ... » read more | |

| We may be approaching the end of the Washington Cap and Invest Program. In just a few weeks, residents of the Evergreen State will be casting votes to either repeal or keep the Program. It could be the end of a Program that we have referred to as a Wild Roller Coaster ride with huge price swings driven by policy rather than fundamentals. From a pricing perspective, there are three ways the program can go from here. First, if the program is repealed carbon prices will no longer exist in Washington. Second, if the program is not repealed it may link with the California\Quebec market. In this outcome it is likely that the carbon price will settle at a price near the current California carbon price because of the relative size of each market. Finally ... » read more | |

| The month of October is displaying some extreme weather events starting with Hurricane Helene and Milton and ending with the above normal temperatures seen across the Westcoast states. In between the two are daytime highs in the low 80’s in the Upper Midwest while the South Central is holding its power demand profile while the wind is fluctuating. Figure 1 | Impact of Hurricanes and/or Tornados Starting with the hurricanes mentioned, the devastation around the two storms is massive as Helene stretched into part of the country that were once deemed safe from catastrophic events that make landfall along the Gulf of Mexico or Atlantic Ocean coastline. Milton made landfall yesterday evening so the daylight hours will start to show the damage created by the category 3 ... » read more | |
