| With the hydro system flowing over 319 kcfs at McNary and 94 kcfs at Lower Granite, the generation out of the turbines is at/near their max capacity. This has led to several of the dams to over-generation spill as the water has nowhere else to go. Despite the higher hydro generation in the region, Midc's heavy load price was strong for today as it averaged $14.09. Using weekend Malin gas that put the implied heat rate at an 8.79. Figure 1 | Midc Heavy Load Price This type of implied heat rate would entice gas fired power plants to nom up as it is ... » read more | |

| The Mid Columbia is a liquid trading hub with a long daily price history. But the daily peak and off-peak Mid Columbia prices provide few insights into the hourly shape or the basis between various Northwest delivery points. Then came the Pacificorp EIM – the game changer. We now have more than a year of – not just hourly data – but rather 15 minute real time price data. While there are certainly some challenges associated with the EIM data, it provides a bright light that can inform decisions the way the standard peak and off-peak Mid Columbia price ... » read more | |

| In the energy industry there is terminology that makes a lot of sense, like on-peak and off-peak when you are talking about a load profile as the highest demand usually come during the daylight hours between HE 7 and HE 22 and the lower demand hours are when businesses are closed and people are getting ready for bed and/or sleeping. When it comes to price, I am still not sure how the West has created its own unique set of on-peak days (Monday - Saturday) between HE 7 and 22 whereas the off-peak days are HE 1-6, 23-24 Monday - Saturday and all day Sunday. If you ... » read more | |

| Baseload supply in the Northeast continued its decline this weekend as NY lost another Nuclear facility. To recap, both NYISO and ISONE were without a major nuclear facility due to a scheduled refueling at Millstone 3 and a maintenance extension at Indian Point 2. On Sunday Nine Mile 2 joined the outage ranks as the unit came down for refueling. The loss of the unit drove up the thermal demand by 1200 MWs in NYISO. Figure 1| NYISO Fundamentals Dashboard - Day Ahead On-peak Average The loss of Nine Mile nuclear ... » read more | |

| Back in October of last year, the Aliso Canyon storage facility experienced a natural gas leak that led to the evacuation of nearly 3000 residents from the Porters Ranch community adjacent to the storage field. Governor Brown called a state of emergency and the largest gas storage facility in Southern California was shut down until a solution could be found. The loss of the Aliso Canyon storage facility in the SoCal Gas system has become a serious reliability concern for gas delivery during the peak consumption months. Aliso Canyon, being the largest storage facility ... » read more | |

| With the warmer weather moving through the Pacific Northwest last week, the Northwest River Forecast Center (NWRFC) started to increase the overall flows on both the Snake and Columbia River tributaries to where this week is showing the former flowing over triple digits by mid-week while the latter has Grand Coulee jumping up to 150 kcfs by Wednesday. Figure 1 | EnergyGPS 10 Day Hydro Generation and Flows Putting both of these together takes the McNary flows from averaging around 240 kcfs last Friday up to 293 kcfs on the 12th and 307 kcfs by the 13th. At these ... » read more | |

| Will the California duck fly to Texas sometime soon? Despite the fact that ERCOT and the CAISO have very different approaches to designing and operating electricity markets, the markets have ended up with the highest concentration of renewables in North America. What happens in one market can foreshadow what may happen in the other. Texas has led the charge in wind development. California has led the charge in solar development. With declining solar panel prices and a tremendous solar resource in Texas, the busbar price for solar projects in Texas keeps ... » read more | |

| California has been breaking records when it comes to temperatures for this time of year over the past couple of days. This has been reflected in the overall load profiles across all of the load serving entities. Figure 1 | CAISO Peak Load - Actual and Forecast With the heat comes the lack of wind across the state as well. As you can see in Figure 2 below, the overall wind output has been down across both regions over the past couple of days. Figure 2 | CAISO Wind Generation - Actual/Forecast You can see that the wind picks up in the North today, while ... » read more | |

| Monther Nature played a good April Fools joke on the Northeast as April (1st) started out with warm weather and some tranquility. How different a weekend makes as Spring has been put on hold in the Northeast as the first full week of April has brought freezing temperatures and snowfall to many parts of New England. Such weather has caused an increase in the overall res/com demand and has wreaked havoc on the current state of the power system in the Northeast. Some of this is due the derate at Stony Point on the Algonquin gas pipeline. The scheduled ... » read more | |

| Over the past few years April has not only been the start of injection season but also the start of summer coal capacity retirements. Last spring almost 13 GW's of coal capacity was retired in favor of new renewable or combined cycle generation. Power burns responded by growing over 2 BCF per day in Q2 2015 alone. There is another round of coal retirements planned this April as well. This is a different year. We do not expect to see any increased power burns this April associated with the shut down of the 4000 MW's of coal capacity listed in Figure 1. Figure 1 | April ... » read more | |
