| In a previous newsletter, we took a look at how the wind penetration within SPP was impacting the overall generation stack as well as curtailments on the grid. In today's newsletter we dive into the neighboring Independent System Operator (ISO), known as MISO, to see how the wind penetration is impacting its respective supply stack. In order to fully understand what is happening on the grid when wind generation ramps up, it is important to know the location and composition of the supply stack in each ISO. For example, MISO has the majority of its wind output in the northern region, which is dependent more on coal for baseload power. In SPP, the southern portion of the footprint has the majority of wind (Oklahoma and parts of Texas). The good news is that is right in the center ... » read more | |

| The northeast celebrated its first day of spring (3/20) prepping for yet another winter storm as a low pressure system barrels up the coast bringing snow and high wind. This will be the 4th "Nor'easter" to hit the region in about three weeks as March has turned out to be a brutal end to an otherwise mild winter. Figure 1 | Satellite Image of the First Three March Nor'easters The storm system is expected to form over the Outer Banks by Wednesday morning and begin tracking towards the Northeast. The system will hit DC first and move its way up to Philadelphia by Wednesday afternoon. The storm is expected to drop a foot of snow over Philadelphia which would the the largest Spring snowfall the city has seen in over 100 years. The snow ... » read more | |

| Over the past ten years we have seen a litany of pipeline projects in the Northeast designed to reverse the flow of natural gas that typically flowed from the Gulf. Transco, Texas Eastern, Tennessee Gas Pipeline, Columbia and Texas Gas Pipeline have all reversed course with the growth of Marcellus and Utica production. Earlier this month, that flow had jumped all the way out to 7.4 BCF per day that is moving from the production basins down to the Gulf. But since that point, the volume has continually slid lower as a number of factors have weighed on the transport economics. After seeing a mild month of January, the Northeast and Midwest have flipped around to the cold side providing well above normal space heating in the Northeast. Dominion LDC load is averaging .3 BCF above the ... » read more | |

| In case you are not aware, it has been a very volatile winter down in Southern California. Not only have the gas prices been volatile, due to SoCalGas' system having both pipeline receipt and Aliso Canyon storage limitations, such that even normal temperatures can result in price spikes, but also the politics have been quite volatile. In this Newsletter we want to bring to light a recent series of letters between California Senator Henry Stern, the California Public Utility Commission (CPUC), and SoCalGas. The spat between these three brought me great reading joy, so sharing is a must. Starting things off at the beginning of March was a very reasonable letter from SoCalGas to the CPUC, found here (snippet in Figure 1). The letter requested immediate ... » read more | |

| ERCOT is the only centralized market in the US without a capacity market. Generators in ERCOT are expected to earn their revenue via the short term energy and ancillary services markets. ERCOT has been tweaking its market design over the years so that real-time energy prices will spike during times of shortage. Along those lines, in June of 2014 ERCOT implemented its Operating Reserve Demand Curve which is known by its acronym, ORDC. The ORDC creates an adder to the real-time price under certain scarcity conditions. When operating reserves fall below a certain level the ORDC kicks in, increasing the real-time price by increasing amounts as reserves become increasingly scarce. The following figure depicts the ORDC in general terms. Figure 1 | ERCOT Operating Reserve Demand Curve ... » read more | |

| The Northeast just can’t seem to get a break. There have been 3 Nor’easters that landed in the region over the past 3 weeks. While none of the recent storms have matched the bomb cyclone of January, each wintry blast brought massive snowfall and heavy winds to the region that has not been able to shake 'Ole Man Winter'. Figure 1 | Northeast Blocking Pattern Nor’easters develop when arctic winds blow down from Canada. The cold air moves southeast, and storms begin to brew as the winds reach warmer air generally found in high pressure systems over the ocean. This has made New England a prime breeding ground for these storms to develop. Over the course of this year, a blocking pattern has held with a low pressure system sitting over the East Coast and a high pressure ... » read more | |

| After a warm and volatile end to February, we have seen temperatures across the Northeast trend down and shift below normal to start this week. Average temperatures in Philadelphia fell into the mid-30s with similar downside seen across the other major PJM load zones. Figure 1| Philadelphia Temperatures Feb 1st - ... » read more | |

| Winter weather is not going away any time soon. This is a stark contrast to what the forecasters called for just four weeks weeks ago. By this time we were expected to have broad warming across the West with normal temperatures in the East and Gulf. This was seen as an early beginning to spring and an early end to space heating for many areas of the country. ... » read more | |

| This has been a busy winter writing about SoCalGas Company. If you are a gas subscriber you can find our NG Market Flashes here, while if you are a power subscriber you will find our California Market Flashes here and here. Coming into this winter season, SoCalGas' pipeline system was in disorder following the early fall explosion on L235 in the Mojave Desert's ... » read more | |

| The states of Washington and Oregon just finished their abbreviated legislative sessions. Democrats in both states attempted to pass carbon legislation. At this point in time we can’t be sure whether the legislation simply didn’t have enough support or if it was just too big a lift to manage in an abbreviated session. My sense is that in a full session, which ... » read more | |
