| Amidst the high power prices that hit southern California this week, was Tuesday’s announcement by LADWP (beautifully reported in the New York Times[1]) that it wants to augment Hoover Dam with a $3 billion pumped storage facility ostensibly powered by renewable energy. Figure 1 | Hoover Dam Hoover Dam is truly a wonder of the modern world. It is an icon known to millions and its specific features and history are well known by many energy geeks, including myself. The “colossus of Black Canyon” was conceived of by engineers and promoters of Southern California development beginning in the 1920s. The 726-foot dam was ultimately built by the “Six Companies”, a consortium of engineering and construction enterprises owned ... » read more | |

| Zone A congestion has seen several spikes so far this summer with LMPs remaining significantly above last year. While part of the elevated prices are undoubtedly due the hot weather, other fundamental factors have also affected the region. In order to get the big picture of what’s going on, let’s first take a look at the constraints in Zone A, as seen in Figure 1. The Niagara dam helps provide hydro generation across the ISO and is also the largest supply source in Zone A. This hydro generation can flow along a 345 kV line out to the rest of the state showing up on the Dysinger East Interface. In order to reach load in Zone A, flows have to step off of the 345 kV and onto a 230 kV system. Comparing this to our road system, flows out of Niagara exit the highway and get stuck in ... » read more | |

| Since the settle of the July NYMEX contract almost one month ago the price action for the August futures has been a one-way ticket south. The contract has lost 26 cents to settle at $2.72 to begin the week. The weight of production growth has overwhelmed the big year-on-year power burn gains throughout the EIA South Central region. That said we are wary of further price drops. There are a number of fundamental factors that have changed in the recent days that cause us to temper any additional downside expectations. The first is we have seen a dramatic rise in the coal to NG price ratio since the beginning of the month. In previous episodes this has been sign of price support for the natural gas curve.

| Over the past several weeks, the West has been the topic of discussion with many in the marketplace as Los Angeles Department of Water and Power saw record loads and some isolated blackouts post 4th of July. Last week, the major transmission highway between the north and south was derated (Path 26) due to an unplanned maintenance outage as well as the Desert Southwest recovering from its monsoon type weather where some key transmission towers toppled (within SRP's balancing authority) due to high winds. Figure 1 | Toppled transmission towers in SRP due to high winds All this got the party started as SoCal Border's cash started to get lively as the marginal megawatt sat in the Desert Southwest as the likes of Pacificorp was buying for their load in their East system as well as ... » read more | |

| Last night my seven-year-old son and I went to a Portland Pickles baseball game. For those of you not in the know regarding this powerhouse baseball squad, the Pickles are part of the West Coast League (WCL), a college wood bat baseball league. Pretty much this league is where good college players come to play during the summer to keep their skills honed. While this is no Major League Baseball, it is great baseball, and when you throw in $10 tickets for the seats from where Figure 1's picture was taken, and $3 beer/soft drinks/hot dogs, I will buy the WCL/MLB value spread all day long. Anyways, as we sat there watching the game, the Corvallis team hit a couple early home runs on us that got my son asking me how they hit the ball so far. I told him that the ... » read more | |

| We are in the full swing of summer, and that means it is fire season. Last weekend I rafted 50 miles of the Deschutes River in Oregon from Warm Springs to Maupin. The Deschutes River drains the Oregon Cascades running south to north before feeding into the Columbia River just above The Dalles Dam. The 500 kV DC lines running from The Dalles to Los Angeles are close to the Deschutes in this part of the state. Just a few weeks ago that portion of the Deschutes was hit by several wildfires, including the Boxcar Fire depicted below. The landscape along the river for most of my trip was charred. We saw a lot of wildlife, presumably hanging out close to the river where there was still plenty of vegetation. Figure 1 | Boxcar Fire in Central Oregon along Deschutes River In recent days the fire ... » read more | |

| Since the founding of the United States of America, we have seen a struggle between the East and West. From squabbles over which coast is the leader in industry with tech in the West and our finance centers in the East, to city residents arguing over which side of town to live. Looking at PJM, the East/West divide is ever present with new natural gas fired plants popping up in the East while the West is mainly comprised of large coal generators. The West Hub is situated right in the middle of PJM between Ohio coal and coastal gas generators which has resulted in an interesting tug-of-war. Looking at Figure 1, we can see that the West Hub LMP reflects this as it generally sits between the East and AD Hub LMPs. Figure 1 | Select PJM Hub LMPs PJM covers a vast geographical area ranging from ... » read more | |

| The time is now in the Lone Star state as the power demand numbers are ready to move up another 2-3 GW during the later afternoon hours. This is due to continued extreme heat hitting the Dallas and Austin areas while Houston is finally joining the party as its daily average moves up into the low 90's for two days. Figure 1 | ERCOT Daily Average Temperatures for Major Cities - Actual and Forecast As a result, the ERCOT Day-Ahead clears have been moving up with Wednesday's hubs sitting around $350 across the heavy load. If you look at the hourly price profile for the North, the later afternoon hours have moved up from the $841 mark yesterday to over $1,500 for today.

| A lot of time has been spent on the Southern California gas market issues this year. This is for good reason. The region has reliability issues due to storage and transportation outages that are causing the supply to be severely constrained. This has largely overshadowed the dynamics that are playing out in Northern California. The two rate cases that were negotiated with the CPUC over the past ten years has caused a number of structural issues on the system that seem to be coming to a head this summer. PG&E had quite a few cost increases go through as a result of the rate cases. That has led to a dramatic increase in transportation prices into and through their system. As a result, the long term contracting for transport services has continually dropped which puts a ... » read more | |

| When people throughout the country think of the Pacific Northwest (PNW) it is my belief that they imagine Washington, Oregon, Idaho, and Montana. At least growing up in the region that is what I always thought of when I heard a reference to the PNW. In the power markets however most traders think of the PNW, or rather, MidC, as Washington and Oregon, with bits of the Idaho panhandle thrown in for good measure (Avista loads). This is the region folks look at for calculating the MidC load associated with its supply/demand balance, using transmission flows to/from British Columbia, Montana, Idaho, Wyoming, and California to finish off the MidC's equation. Estimating the flows to/from these other regions is always difficult, and best done with a production cost model ... » read more | |
