| Ever wonder how much is flowing on the interties in and out of MISO? Or, Interested in which balancing authorities are giving or receiving megawatts from MISO? Energy GPS is now offering a daily MISO Transmission dashboard that gives provides insight into the hourly activity associated to market participant schedules in the day-ahead market. The figure below was featured in yesterday’s MISO transmission dashboard. It shows day-ahead planned transmission over the last week in and out of the three major MISO regions: North, South, and Central. Imports into MISO are positive while negatives represent out megawatts flowing out the region. In the last week, South MISO has mostly exported, and Central MISO has mostly imported while North MISO has seen a mixture of the two. If ... » read more | |

| South Central gas markets exited winter with a modest softer tone, as power-sector demand failed to match prior-year levels for much of the first quarter. Even during periods of colder weather, the lift in gas burns was brief and faded quickly, pointing to a system that required less gas overall. This wasn’t due to a lack of electricity demand—total load still reached typical winter peaks—but rather the growing impact of renewables and less harsh winter conditions. Stronger wind and solar generation, supported by continued capacity additions, consistently reduced net load and displaced gas-fired generation, keeping overall gas demand modest.

| I’m not a big AC guy. In the summer I prefer open windows, sounds of birds, a breeze maybe, and I don’t mind sweating it out a little bit on warm summer nights. If it gets too hot, then usually a fan in the bedroom will do it for me. But I live in a democratic household where my wife and I each get one vote and according to our bylaws, the vote of the matriarch breaks all ties. We live in an older home, built in 1905, with deep awnings, a great wraparound front porch but smaller closets and bathrooms and importantly, no central AC like newer homes have. So, the annual debate comes down to when exactly I’m going to install the window AC units as the weather begins to warm. I generally push for some time in mid-August or never (Figure 1), while my wife usually votes for ... » read more | |

| Higher daytime highs this early in the spring are not a common occurrence across the Northeast but no worries as Mother Nature is bringing back moderate temperatures heading into the weekend. This past week has seen an uptick in prices across Northeast ISOs as planned outages to both generation and transmission swung the make-up of the supply stacks. This leads to entities that once were sending megawatts across the transmission lines to keep volume at home, which then results in the higher marginal cost of energy. The good news for the power entities that saw their peak load values increase to create shortness is that spot natural gas prices are modest as the molecules do not have to compete with any sort of heating demand.

| Our latest Renewable Quarterly report, published yesterday, takes a retrospective look at the winter and the differences that played out across the country. One of the key points from this winter was the geographic split in cold versus warmth. While much of the country was dealing with a blast of frigid winter weather during January, CAISO (along with the rest of the West) was facing the opposite. Unusually warm temperature characterized the quarter, keeping the cold at bay in January and February and even bringing a burst of significant heat during the middle of March. We can see how stark the difference was from the norm in the figure below, which compares total monthly HDDs for CAISO against previous years. January and February HDDs came in well below the norm, while the month of March ... » read more | |

| On Monday, pool prices shot over $620/MWh in Alberta. As is often the case, lower-than-expected wind generation was part of the equation that led to volatility. Renewable and demand forecasts on Monday morning expected a peak net load level of under 10 GW. In just a few hours, that forecast was proven to be incorrect as net load topped out at 10.3 GW. Pool prices started to move up to the high double-digit range in HE 7, then to the low triple-digit range in HE 8-9 before finally shooting over $600/MWh in HE 10. Exacerbating the tightness was a previously scheduled transmission maintenance that left the Alberta grid mostly on its own.

| As Western Canada transitions out of winter, the shift from withdrawals to injections has occurred, with storage dynamics now shaping the market through a different lens. Alberta entered the heating season from a position of strength, with inventories near maximum capacity at 475 Bcf, signaling ample supply heading into peak winter demand. Through the season, drawdowns were modest, with storage bottoming just below 300 Bcf—largely in line with recent years. Despite periods of colder weather, the system never faced meaningful stress, as strong production and manageable demand swings kept inventories resilient rather than pushing toward tighter levels.

| Western Canada has a lot going on these days with LNG Canada trying to take advantage of the higher global prices associated to the Middle East conflict that is now on its second month. This has helped keep AECO prices afloat for the time being while Westcoast Station 2 works through planned maintenance that typically occurs after the winter season. On the electricity side of the equation, British Columbia is sitting on the healthiest snowpack in the entire West (US and Canada) and that is going to help keep the generation values for the Pacific Northwest at levels higher than the past three years starting in June and working through July. When it comes to electricity prices in the West, two markets stick out with the first being California’s Independent Operations (CAISO) and the ... » read more | |

| As the first week of April concludes, the focus shifts from monitoring heating degree days (HDD) to evaluating cooling degree days (CDD) for potential increases in power demand. This seasonal transition also introduces weather patterns that influence both wind and solar generation across SPP’s region. We detailed the renewable curtailment impact around such conditions in our latest content publication, titled SPP Curtailment Call. SPP-South has seen daytime temperatures in the 80s lately, while SPP-North remains cooler, with Omaha at 58 degrees and Oklahoma City bridging the gap at 75 degrees. By the weekend, Omaha's high temperature will approach Oklahoma City's, and Little Rock will reach 84 degrees. When daytime highs exceed 75 degrees, CDDs become the focus for degree-day ... » read more | |

| One week ago our blog focused on an important event each April in the Pacific Northwest, the beginning of spring fish spill. Fish spill for the 2026 water year began last Friday, April 3rd with the four dams on the Lower Snake, from Lower Granite down through Ice Harbor, and marks a transition in hydro operations lasting from early April late into the summer (the past two years ending on July 31st but this year is set to continue through the end of August). For spring spill, a large portion of all outflows is redirected away from the powerhouses and into spillways to travel over the top of the dams, instead of through the dams for generation. We can see the impact on overall hydro generation for the Lower Snake projects together in the figure below, which plots average generation by day ... » read more | |
