Moderate weather in the Midwest, Northeast, and Pacific Northwest this winter should diminish total residential and commercial electricity and natural gas demand – and ample production and storage will drive prices down. That’s a promising scenario for the energy industry and a reason for ratepayers to “chill out” about how the climate will affect their consumption, according to a report released on October 15 by the Federal Energy Regulatory Commission’s (FERC’s) Office of Enforcement.
The 2015-2016 Winter Energy Market Assessment, presented by staff at FERC’s regular meeting, finds that, as always, weather is one of the primary and least predictable drivers for the natural gas and electricity markets. However, the three-month outlook for December 2015 through February 2016 is promising: In fact, some analysts at the National Oceanic and Atmospheric Administration (NOAA) project this winter to be 7 percent warmer than last year’s and 3 percent warmer than the 30-year average, the researchers reported.
Temperate conditions in the Midwest and Northeast should help depress total residential and commercial natural gas demand during the winter, although LNG exports and industrial facilities could add to total demand as operations begin.
Natural gas storage inventories began this year’s storage injection season (running from April 1 through October 31) below the five-year average, the report states. However, storage refilled quickly during the spring and summer, as strong production growth outpaced demand. As a result, the assessment shows that natural gas inventories may reach 4 trillion cubic feet (Tcf) by the end of this month, which would be a record level. Even if inventory withdrawals matched Polar Vortex levels this season, the research finds that storage would remain adequate.
What’s more, the U.S. natural gas market should be well-supplied by producers this winter. Gains early in the year helped total production set a new year-to-date record at 72 billion cubic feet per day (Bcfd), up 4 percent.
Electricity prices also increasingly track natural gas markets as gas-fired generation increases. In addition, increased integration of renewables can cause price volatility, particularly in the Western markets, such as the California Independent System Operator (CAL-ISO).
In early September, FERC approved a three-year extension to the New England Independent System Operator’s (ISO-NE’s) Winter Reliability Program. The Program is designed to prevent over-reliance on natural gas-fired generators, as well as to implement other proactive measures during the winter months. The three-year term is intended as a bridge to the initiation of the Pay-for-Performance, capacity market reform. Once Pay-for-Performance has been implemented, ISO-NE believes that the winter reliability program will no longer be needed.
Overall, the report finds, regional transmission organizations (RTOs) have increased situational awareness and understanding of natural gas market fundamentals. Maps highlighting natural gas pipelines that overlay electric transmission maps exist in many RTOs, including the New York Independent System Operator (NYISO), ISO-NE, and Southwest Power Pool (SPP). These maps help system operators plan for fuel restrictions on their system when making dispatch decisions. More generally, RTOs – and particularly CAL-ISO – have learned more about natural gas system outages and the domino effects on the electric grid.
In addition to a broad overview, the market assessment offers a look at RTO/ISO preparations for the coming season, and two up-close reports on efforts in CAL-ISO and ISO-NE.
