Power prices fall after polar vortex; ERCOT facing another hot summer

Power prices have fallen back down as warmer than normal temperatures follow the polar vortex. ERCOT is facing another summer of tight reserve margins, with summer 2019 forecasted to be hotter than normal.

Utility Highlight

  • The current Price to Compare for Connecticut’s United Illuminating (UI) Residential Service rate class is $0.112263/kWh, in effect from January 1, 2019 to June 30, 2019. This rate is a 24% increase from the previous rate of $0.090496/kWh for the July 1, 2018 to December 31, 2018 price period.

  • TrueLight Energy’s expert analytics and proprietary models indicate that headroom in UI is available in the 6, 9 and 12 month terms. Headroom of $0.01171/kWh and $0.01409/kWh is likely for the 6 and 9 month terms, respectively. Please contact TrueLight should you need more detailed information about current default rates and headroom, or would like to receive our forecast for future default rates and headroom by market.

  • Over the last week, the UI Connecticut ATC 12-month strip has trended slightly lower, falling by approximately 3% to finish at $43.44/MWh yesterday.

  • In the past 3 months, the ATC strip has reached a high of $58.43/MWh on November 20, 2018 and a low of $42.87/MWh a month ago on January 4, 2019.

Natural Gas

  • For the week ending January 25, the EIA reported net withdrawals from storage of 173 Bcf, which is higher than last year’s net withdrawals of 126 Bcf for this week and the 5-year (2014–18) average net withdrawals of 150 Bcf.

  • Working natural gas in storage totaled 2,197 Bcf, which is 14 Bcf (-0.6%) lower than last year’s level and 328 Bcf (-13%) lower than the five year average of 2,525 Bcf. Total working gas is back within the five-year historical range.

Supply & Demand

  • Average total supply of natural gas did not change week/week. Dry natural gas production remained constant, while net imports with Canada increased 7%.

  • Total US consumption of natural gas increased 8%. Consumption for power generation was up 6% week/week, industrial sector consumption gained 4%, residential-commercial consumption increased 11%, and exports to Mexico increased 3%.

  • US LNG exports increased week/week, with seven vessels departing US ports for a combined 25.5 Bcf.

Market Intelligence

  • ERCOT expects to see tight reserve margins (the excess capacity buffer during peak demand) for summer 2019, as higher forecasted summer peak load and fewer than expected new generation projects drive reserves down. Furthermore, NOAA forecasts a hotter than normal summer this year in Texas, which would drive up demand as folks crank up the AC to cope with the heat. Similar to last summer, a tight supply stack would result in price spikes and greater risk for brownouts. ERCOT remains confident in its ability to navigate another hot Texas summer.

  • As coal demand in the US has continued to decline, the number of active coal mines has shrunk by more than half, from 1,435 mines in 2008 to 671 mines in 2017. This decline has been largely due to economics, with smaller and less efficient mines being the first to close. The majority of mine closures have occurred in the Appalachian region, including both underground and surface mines.

  • According to the EIA, the US is on track to export more energy than it imports by 2020, which hasn’t occurred since the 1950s. The US has imported more energy than it exported every year since 1953, however, increases in crude oil, natural gas, and natural gas plant liquids production are on track to outpace consumption by 2020. This trend is expected to continue to 2040- 2050 and then once again return to importing more than exporting.


  • A brief warm-up to start the month of February quickly gives way to another round of winter cold, this time not nearly as severe as the last week of January but still a sufficient arctic air mass likely to drive well below normal temperatures across most of the western US. The Pacific Northwest is expected to see the strongest cold anomalies.

  • Cold temperatures will return to the Northeast as well, though this will be more of a return to typical February temperatures. Further south along the Atlantic coast, temperatures trend warmer relative to seasonal norms.
