El Niño helps reduce US winter heating demand and fuel prices

Above normal temperatures during the 2015 - 2016 winter were a key factor in lowering heating demand and winter fuel expenditures. Compared with the 2014 - 2015 winter, propane and heating oil demand decreased by 16% and 45%, respectively, and residential electricity demand decreased by 6%. The 2015 - 2016 winter season (October through March) was 15% warmer than last winter, driven in part by one of the strongest El Niño events in decades.El Niño is a large scale warming event that affects temperature and precipitation patterns in the Pacific Ocean. It occurs every three to five years, and it is caused by warmer than normal ocean temperatures in the east-central equatorial Pacific. El Niño events typically last 9 to 12 months. The 2015 - 2016 El Niño was one of the three strongest on record, and contributed to the warm winter weather experienced in the US.

In addition to record high winter temperatures reducing the demand for space heating, abundant natural gas supplies and low crude oil prices were major factors in lowering heating fuel prices. Warm winter temperatures reduced the overall number of US heating degree days (HDD), a temperature-based measurement reflecting the heating needs of buildings in a location. At the national level, the number of heating degree days was 18% lower than the previous winter season and 12% lower than the National Oceanic and Atmospheric Administration's forecast in September 2015.

Highlights for the four most common heating fuels include:

Natural gas

Nearly half of all US homes use natural gas for space heating. Residential natural gas prices during the winter of 2015 - 2016 were about 5.6% lower than in the previous winter. Throughout this past winter, natural gas inventories remained high. As of 7 April, working natural gas in underground storage increased to 1472 billion ft3, 69% higher than the level at the same time in 2015.

Heating oil

Prices for petroleum-based fuel have also been lower because of falling crude oil prices. Residential heating oil prices were about 29% lower this winter compared with the previous winter. As the El Niño event dissipates and demand increases, refinery heating oil prices are forecast to increase 18% by next winter.

Propane

Residential propane prices remained relatively flat during the winter season, averaging US$1.98 per gallon. As of 1 April 2016, US propane stocks were up by 2.0 million bbls to 64.9 million bbls, 6.9 million bbls (11.9%) higher than a year ago. On average, US households paid 15% less for propane this winter compared with the previous winter. In the Midwest, which uses more propane than other regions, prices declined by more than 22% from the previous winter.

Electricity

Electricity prices change more slowly than the prices of heating fuels because electricity rates in many areas of the country are set using regulatory mechanisms with long time lags. Residential electricity prices fell slightly, declining 0.5% from winter 2014 - 2015 to winter 2015 - 2016.
