WASHINGTON, D.C. – The U.S. Energy Information Administration’s (EIA) short-term energy outlook projects gasoline prices will fall even further during the fourth quarter of 2013.

The weekly U.S. average regular gasoline retail price dropped by 18 cents per gallon during September, ending the month at $3.43 per gallon. EIA’s forecast for the regular gasoline retail price averages $3.34 per gallon in the fourth quarter of 2013. The annual average regular gasoline retail price, which was $3.63 per gallon in 2012, is expected to be $3.52 per gallon in 2013 and $3.40 per gallon in 2014.

Contributing to the lower gas prices, Brent crude oil spot prices decreased from a recent peak of $117 per barrel in early September to $108 per barrel at the end of the month as some crude oil production restarted in Libya and concerns over the conflict in Syria moderated. EIA expects the Brent crude oil price to continue to weaken, averaging $107 per barrel during the fourth quarter of 2013 and $102 per barrel in 2014. Projected West Texas Intermediate (WTI) crude oil prices average $101 per barrel during the fourth quarter of 2013 and $96 per barrel during 2014.

Meanwhile, EIA projects average U.S. household expenditures for natural gas and propane will increase by 13% and 9%, respectively, this winter heating season (October 1 through March 31) compared with last winter. Projected U.S. household expenditures are 2% higher for electricity and 2% lower for heating oil this winter. Although EIA expects average expenditures for households that heat with natural gas will be significantly higher than last winter, spending for gas heat will still be lower than the previous 5-year average.
