EIA: U.S. natural gas consumption rises in 2019

U.S. natural gas consumption increased by 3 percent in 2019, reaching a record of 85.0 billion cubic feet per day (Bcf/d), according to the U.S. Energy Information Administration (EIA).

New natural gas-fired electric capacity and lower natural gas prices led the increase in domestic natural gas consumption, EIA said in its Natural Gas Monthly.

U.S. natural gas consumption grew in the electric power sector by 2.0 Bcf/d, or 7 percent, but remained relatively flat in the commercial, residential, and industrial sectors. Exports by pipeline to Mexico and as liquefied natural gas (LNG) grew by 0.5 Bcf/d and 2.0 Bcf/d, respectively.

In 2019, the electric power sector consumed 31.0 Bcf/d, or 36 percent, of total domestic U.S. natural gas consumption. Natural gas-fired electric capacity additions grew in 2019, especially in the PJM Interconnection, which serves the U.S. mid-Atlantic region.

Natural gas continues to account for the largest share of electricity generation after first surpassing coal-fired generation on an annual basis in 2016.

In 2019, natural gas accounted for 38 percent of total electricity generation, followed by 23 percent for coal and 20 percent for nuclear. New natural gas generation capacity additions have continued to displace coal-fired power plants; about 5 percent of the total existing U.S. coal-fired capacity was retired in 2019.

Weather largely drives annual and monthly fluctuations in natural gas consumption. During the winter, U.S. natural gas consumption levels are at their highest because natural gas is the predominant fuel for space heating in the residential and commercial sectors. In 2019, demand for natural gas as a heating fuel was similar to 2018 demand.

Natural gas consumption has a smaller peak in the summer when demand for air conditioning, and therefore electricity, is greatest. In the summer of 2019, relatively high temperatures increased electricity usage and natural gas consumption. The United States set a monthly record for U.S. electric power sector consumption of 41.1 Bcf/d in July 2019, then surpassed that level to reach 41.6 Bcf/d in August. The electric power sector has been shifting toward natural gas in the past decade because of competitive natural gas prices and power plant technology improvements.
