| Temperatures started to move above normal over the course of this weekend with Monday reaching the high watermark at 93 degrees in Columbus, Ohio. The rest of the Northeast was not far behind as Boston and New York both moved into the high 80s. As people cranked up their AC units, demand across the regions rose as well. Looking at Figure 1 we can see a red blob covering the entire northeast for Monday. Figure 1 | Historical Temperature Anomaly for June 18th The rise in temperatures caused electrical demand to hit its high so far this summer. With the hottest weather in the PJM region, the West Hub LMP rose to $64.19, head and shoulders above the rest. Looking at figure 2, we can see a cascading effect as LMPs settled a bit lower as you move north. Figure 2 | Select Northeast LMPs for ... » read more | |

| Aloha, from the island of Oahu!!! Over the past couple of days my family and I have been able to hangout in Honolulu while our son's soccer team participates in the FarWest Regional Tournament. On our first full day, local friends took up to the North Shore where we got to drive past the Dole Plantation Factory (we did not stop and take a tour). A little further up the two-lane road, over the tall stalks of grass that shielded us drivers, was the first glimpse of the new regime on the island. In the distant stood anywhere between 15-20 wind turbines, nonchalantly spinning as the wind blew off the Pacific Ocean and up the hillside.

| Coming into this week there were big expectations for power burns. The net load was expected to soar from 471 to 511 GWa which at face value should have produced the highest power burns of the year. But we noticed something different about yesterday's net load to power burn relationship. Gas consumption remained relatively flat despite the material gain in power demand. The original forecast was showing power burns climbing to over 35.5 BCF per day but the realized burns only measured 33.7 BCF. The implication was that there was another generation source getting dispatched ahead of natural gas once the load moved up to levels usually seen in July and August. Figure 1 | Lower 48 Net Load and Power Burns for the Past 20 Days Coal generation still remains a significant premium to natural ... » read more | |

| Every year the water year in the Pacific Northwest is different. Not only is the cumulative volume of water that goes through the various dams within the river system different each year, but so is the timing of when the snow melts and hits the rivers. Further, every sub-region of the PNW (Snake basin, west side, Willamette Valley, Above Grand Coulee, etc) receives different volume and timing of their respective flows. All of this said, at some point every year each region's runoff comes to an end. As you can see in Figure 1, flows at The Dalles are coming off hard, a strong indicator that this year's runoff is nearing a wrap. Figure 1 | Outflows at The Dalles (KCFS) From a generation perspective, as seen in Figure 2, hydro generation has fallen from a peak ... » read more | |

| The first time I analyzed batteries as a wholesale power market asset was in 2013. A private equity outfit was looking into a battery company and asked me to help them evaluate the wholesale electricity market application of the batteries. The company was too far over its tips financially, and the applications for batteries in the electricity sector were largely behind the meter load management plays. Given the costs at the time and the revenue opportunity, there was simply no way to make the math work outside of a few niche opportunities. I learned a ton on that project about battery control technology, state of charge, degradation, and behind the meter applications. I learned about how accurately batteries can follow a signal and how much better they perform on performance based ... » read more | |

| The recent heat wave that moved through the Ohio Valley is a reminder to those in the Northeast that summer is almost upon us. In many markets across the country, electrical demand peaks during the summer time. As people start to switch on their AC units, driving up load, the ISOs are doing their best to have all resources available. With the calendar shift between seasons just a week away, we are seeing resources in PJM and New York return from maintenance. Figure 1 | Columbus Historical (Bar) and Forecast (dotted lines) Temperatures Last week in our newsletter we discussed how the Zone A LMP rallied due to line outages in the region. Multiple transmission lines coming out of Niagara took planned maintenance outages which drove congestion to the highest levels we have seen in ... » read more | |

| Over the past couple of weeks, we have written about the weather in ERCOT as well as the recent price spike that drove HE 16 on June 5th up to $8,000 (ERCOT's Price Spike). In the article underlined, we detailed the key components one needs to watch for as we move into the back half of June and look forward to the months of July and August. One of the key components is the ERCOT wind profile as its volatility has an impact on the net load numbers on the grid. Figure 1 | ERCOT Wind Generation Hourly Profile - Actual and Forecast In the graph above, it shows the hourly ERCOT wind generation by day for the last 8 days as well as the next 7 day forecast. If you look to the far left, you will see the later afternoon hours dip down below 1.8 GW HE 14 and sit around the 2.1 GW ... » read more | |

| SoCal Gas continues to have a number of issues on their system that are expected to continue through next winter. Pipeline capacity into the Los Angeles Basin is severely restricted due to a number planned and forced outages. The result is that moderately high gas demand days will have to be met with storage draws to maintain pipeline reliability. That poses a bigger problem. The beleaguered Aliso Canyon storage cavern has also added to the supply woes because of the restraints placed upon its use by the California Legislature. The government imposed mandate will keep the regions largest storage cavern sitting on the sidelines unless its usage is deemed crucial to maintaining system integrity. In anticipation of the supply issues during the peak of summer heat, SoCal ... » read more | |

| A month ago in a newsletter found here, we discussed the fact that the bulk of the CAISO's stated quarterly economic benefits are mainly driven by the fact that the $10 to $30/MWh in transmission costs that participants see in the day ahead WECC markets, simply vanish in EIM. In today's Newsletter I would like to discuss what companies will benefit most from a market that is more about optimizing free transmission than it is about true imbalance (generation/load deviation from forecast). With that, let's start off with this past quarter's benefits, as seen in Table 1. You will notice in here that the CAISO, PacifiCorp, and APS are the biggest winners, with the first two making the majority of the haul. The CAISO's benefits are pretty obvious, as they are able ... » read more | |

| As an electricity market analyst I’d like to take this opportunity to thank the states of Texas and California for keeping work interesting for me (and keeping me employed). As the grid continues its long journey transitioning from thermal resources to renewables, California (What's your CCV West Power?) and Texas (ERCOT's Price Spike, The Heat is On (ERCOT Stack) are the pioneers. These unlikely renewable bedfellows have taken very different paths to this point and likely have different paths looking forward. The ERCOT renewable engine runs on a combination of abundant, cost-effective renewable resources and competitive market forces. Renewables are cheap compared to other alternatives, and forward curves support new build economics. Importantly, the renewable build out in Texas ... » read more | |
