| The past two EnergyGPS Newsletter Articles have detailed the wind penetration and impact to the supply stack in SPP as well as how it and the hydro generation in the Pacific Northwest has reshaped how the month of February has traded. The former has had little impact on the overall natural gas consumption as there is a point of increased wind canabalizing itself and curtailments ultimately occur. The latter does has a direct impact on the natural gas consumption as there are days when both the wind and hydro output is enough to not need as much thermal generation so the marginal cost of energy has to shift down into the lowest portion of the coal stack.

| Recently, we took a look at the changes in the SPP market. It’s easy to miss gradual changes that happen over the course of years, but comparing years can reveal dramatic trends. 2019 was a “wet” wind year while 2018 was a “dry” one. The graph below shows a couple of important details about this trend. In the top pane, the yellow line shows 2019 wind gen and the green shows 2018 wind gen. 2019, unsuprisingly, is higher. However, this isn’t attributable merely to new installations. The bottom pane shows capacity factor, a measure of how efficient a generator is. EGPS defines capacity factor in this instance as the generation for an interval divided by the maximum generation. 2018 capacity factor is each interval of 2018 wind generation data, divided by ... » read more | |

| Yesterday was a travel day for me as I am speaking at the East Meets West conference in Vail, Colorado. As I booked by ticket, the seat selection was important to me as I wanted to have a window seat not by the wing. This is so I could take some time to look out over the mountains as I wanted to see first hand how much snowpack sits along the Snake River Basin, the mountains around Jackson Hole and what is happening in the Rockies. I got my seat and was impressed with what I saw as the mountain basins were stocked with decent snowpack, but it was not until I was in the shuttle from the airport in Eagle to Vail that I realized things will be changing as the avid skiers were talking about feet of new snow. I then received a text on my phone from United Airlines that ... » read more | |

| Over hte past couple of days, Texas weather has moved from being warm to a bit of a chill as temperatures drop across the Lone Star state. For example, the likes of Dallas and Houston have shifted down from the upper 60's for a daytime average to more like 45 degrees and falling today and tomorrow. Figure 1 | Daily Average Temperatures for Key Demand Cities - Texas The shift down has sparked both power burns and rescom demand across the state where the former is tied to the lack of wind that has dropped off as well. If you look at the following net load graph and North Zone price action, you can clearly see that the ERCOT market needed to send a price signal to market participants during the later afternoon hours as the grid needed more natural gas-fired generation to turn on ... » read more | |

| The development of the LNG export industry has become one of the most important pieces of the continental balancing dynamic. In just five short years the volume total has grown from 1 to 9 BCF per day and that total is expected to grow this summer with the completion of Kinder Morgan's Elba Island terminal in Georgia. This would not be possible without the development of the global demand for natural gas. For years, exporters such as Cheniere, have relied on markets across the Atlantic for their cargoes as the prices were multiples higher than what we had seen in the United States. Figure 1 | Lower 48 LNG Export Volume But the price advantage is not what it used to be. In the past year the spread between the United Kingdom's National Balancing Pool (NGP), which is a proxy for ... » read more | |

| Yesterday was one of the biggest sporting events that occurs around this time each year, it is the National Football League's ultimate game called the Super Bowl. This years match up was goiing to be exciting as the Patrick Mahomes led Kansas City Chief took on the San Francisco 49ers and their impressive defense. The game was better than advertised as the both teams played hard in the first half to where the game was tied going into halftime (10-10). After an excellent halftime performance by Shakira and J-Lo, both teams trotted onto the field in Miami to determine the winner and be crowned World Champions. Figure 1 | Super Bowl Sunday - Chiefs vs. 49ers The third quater belonged to the 49ers as they busted open a 20-10 lead on two nice drives of ... » read more | |

| Over the past few months, we have written about the big uptick in wind generation across the state of Texas over the past few years and its impact to the ERCOT power grid. In the blogs/articles we have touched on how Texas has become the leader when it comes to wind capacity being placed on the grid and how it has impacted rule changes such as the Operating Reserve Demand Curve (ORDC) uplift chart during the summer months. Such a price signal is good as it is the lever the system operators can pull in the real-time market as well as a proxy for developers to incorporate into their pricing forecast model to see if a project is economically feasible to finance and put what we would call steel in the ground.

| Yesterday saw the February contract roll off the board as it settled just under $1.90. This symbolizes another month has liquidated (January 2020), which means we are one step closer to the end of the current winter season. As we all know from the EnergyGPS daily commentary within our subscription packages, Mother Nature has delivered a pretty mild winter season to date. The current 15-day forecast is not changing that mindset as the next 5-day period is showing the East, Midwest and parts of the South Central all warming up for Super Bowl Sunday and the start of a new month. The 6-10 day period is holding serve when it comes to warmer weather while the 11-15 day period is hovering around what is considered the normal marks for HDD accumulation. Figure ... » read more | |

| We have written about the wind penetration across the middle third of the country with both SPP and ERCOT really stepping up over the past five years. In fact, when it is all said and done, the Lone Star State is paving the way to be the leader across all of North America as it's cumulative peak generation topped the 19.8 GW this month. The previous peak wind generation number was sitting at 19.2 GW for most of 2019. Figure 1 | ERCOT Wind Generation Breakdown - Monthly The graph in Figure 1 breaks down the monthly capacity factor in the top pane with the bottom pane representing the two parts that make up the capacity factor ratio. The numerator is the monthly average generation, which is represented by the bars while the denominator is the cumulative peak generation ... » read more | |

| The ongoing issues with the lack of heating load across the continent has resulted in a forecasted surplus of gas storage inventory this summer. The current expectation is prior to next winter the Lower 48 will see the in ground supply approach 4 TCF. That bumps up against the storage capability. In an effort to avoid end of season balancing issues, actions are being taken now too incentivize power burn demand. By doing this the increased gas dispatch can buffer the surplus in the balancing. But in order to do that, the gas prices must cooperate. By dropping cash gas values, the heat rates will position gas generation as an advantage in the merit dispatch. We are seeing this in every major power market across the US grid. Figure 1 | Selected Spot On Peak Heat Rate ... » read more | |
