| Last week, specifically April 13th, ERCOT conditions caught the market off-guard as the real-time prices skyrocketed to the new regulated cap of $2,000/MWh. The event was a function of the trifecta components known as outages, under-scheduling of load and over-forecasting of renewables in the form of wind generation. The outage numbers were strong as the fallout from the February winter storm still has unit's offline along with planned maintenance to the likes of the South Point nuclear facility. Under-scheduling of load always makes the grid shorter than expectation and with a warmer weather forecast; the grid was on a heightened alert scenario where ERCOT was calling for the evening peak power load to be quite strong. Mother Nature decided to sprinkle a little more ... » read more | |

| This week has a lot in common with the events of this past February. During that fateful cold snap Texas experienced one of the biggest grid outages on record as temperatures dove well below the freezing mark. While the cold had a big impact on the heating load one of the other qualities was the amplification of the jet stream. By flipping from an east to west flow across the continent to a highly amplified state, it caused the wind direction through much of the installed wind farms to become less effective. Combined ERCOT and SPP wind output fell from 25 to 10 GWa for the second week of that month. That drop off in renewables put more pressure on the grid thermal commit to balance the record electric demand. Figure 1 | WSI Forecast Map for April 20 This week is seeing the ... » read more | |

| A drought is caused by drier than normal conditions that eventually lead to water supply problems. In the West, there are three regions that get our attention each year with the Pacific Northwest being the major system that everyone has eyes on as early as November and December of the previous year as Mother Nature can deliver snowpack accumulation or set the tone for what would be consider a low water year if temperatures are above normal and the only precipitation is rainfall. California is the second region that gets the attention of market participants as it only takes three big storms to change the course of a water year. Just like the Pacific Northwest, the flipside of a trifecta winner is when Mother Nature only delivers a single storm and if the pattern persists ... » read more | |

| The good researchers at Lawrence Berkeley National Labs (LBNL) have put out an excellent piece of research quantifying the reduction in power sector CO2 emissions from 2005 through 2020: “Halfway to Zero: Progress towards a Carbon-Free Power Sector” with Ryan Wiser listed as the lead author is worth a read. All of the figures used in this blog come from the LBNL report. https://eta-publications.lbl.gov/sites/default/files/halfway_to_zero_report.pdf In typical LBNL form, this work is rigorous and detailed. Here’s the punchline, the US Energy Information Administration’s 2005 Annual Energy Outlook projected 2020 CO2 emissions from power supply of 3,008 MMT. Direct power sector CO2 emissions were 1,450 MMT. This is 52% lower than projected level and 40% lower than ... » read more | |

| Daytime temperatures in ERCOT shifted up this week, and ultimately drove the power demand to new heights for this time of year. If there is one thing that continues to stand out from the February cold snap, it is the fact that residents of Texas consume a considerable amount of electricity and that seems to be the trend compared to the forecast the past few days. On Tuesday the 13th, real time loads came in much higher than expected were compounded by wind coming in well below schedule and low solar output. ERCOT briefly called for energy conservation from the public on the 13th and issued watches related to its Physical Responsive Capability, but avoided declaring an emergency or shedding load. Still, this week’s warm weather has caused significant real time pricing activity ... » read more | |

| Power burns are a key component to the overall natural gas supply/demand balance and over the years, we have seen the transition from a peer regression model analysis tied to temperature to that of trying to figure out the overall wind generation throughout a given day and how much sunshine will be showing up in certain part of the country. The other attribute that goes with the power burn component is the regulatory/policy aspect as the push for a carbon free market continues down the path of being pursued worldwide. Within the Lower 48, California has spearheaded the fully integrated model when it comes to carbon-based initiatives starting with their Renewable Portfolio Standard (RPS) mandate and extending it with a carbon policy a few years back. Mandates on the ... » read more | |

| This spring was expected to be different. The economic recovery from last years COVID lock downs was expected to push power burn totals above last years levels and provide a base for higher natural gas prices through the summer. But it is not turning out that way. It is not just one factor but many that are leading to the under performance of power burns. Since February the total has posted steadily below the comparisons to last year and 2019 despite the fact that the economy throughout the country is rebounding. And this is the single biggest factor as to why the NYMEX continuous contract has dropped off from $2.84 to $2.55 since the beginning of March. Figure 1 | Lower 48 Power Burns Every region of the country outside of the Rockies is showing a power burn deficit to last year. In the ... » read more | |

| The Pacific Northwest is in full fish spill mode now that April 10th has come and gone, which means that the hydro system is diverting water that once flowed through the turbines at the facilities on the Lower Snake and Columbia to that of the spillway for the little ones migrating to the ocean waters. Figure 1 | Fish Spill Portion of the Pacific Northwest Hydro System During this time of year, there are several moving components that have an impact the overall hydro supply output during the month of April. We discussed some of these in the Platinum Package special report published at the end of March 2021 called Pacific Northwest Hydro 2021. On a more routine basis, we dive into the details as part of the EnergyGPS Pacific Northwest Hydro Package that we offer to clients, where we ... » read more | |

| When Winter Storm Uri pummeled Texas in February, many generators stopped performing on their contracts for physical delivery and claimed force majeure. Many wind projects with fixed quantity hedges with banks played the force majeure card as their blades froze due to the cold temperatures. Of course, the banks and the power marketers on the other side of those trades likely didn’t see it that way. In general, those entities purchase “firm LD power” and they expect delivery else they will replace the energy and charge the seller liquidated damages (“LDs”). The billion dollar question (literally) is whether the high demand, unit outages, and curtailment of load that directly resulted from Winter Storm Uri qualifies as a force majeure event. I’ve been ... » read more | |

| There is a little time before the summer heat is upon us in Texas but ERCOT is working its way through the first real warm period of the spring as temperatures in Houston are projected to hit 86 degrees later today then hold with daytime highs in the low 80's over the weekend. Dallas and Austin are not too far behind when it comes to the influx of Mother Nature's warmer weather fairy dust sprinkled over the Lone Star State. The warmer weather does not equate to sunny skies throughout as some areas of the ERCOT's footprint will be dealing with cloud cover over the next 48 hours. Figure 1 | Texas Temperature Forecast - Daily Average by City Similar situations in the past created a transition from moderate power demand to that of big increases during the later ... » read more | |
