US natural gas consumption increased by 3% in 2019, reaching a record of 85.0 billion ft3/d, according to the US Energy Information Administration’s (EIA) recently released Natural Gas Monthly. New natural gas-fired electric capacity and lower natural gas prices led the increase in domestic natural gas consumption.
US natural gas consumption grew in the electric power sector by 2.0 billion ft3/d, or 7%, but remained relatively flat in the commercial, residential, and industrial sectors. Exports by pipeline to Mexico and as LNG grew by 500 million ft3/d and 2.0 billion ft3/d, respectively. In 2019, the electric power sector consumed 31.0 billion ft3/d, or 36%, of total domestic US natural gas consumption. Natural gas-fired electric capacity additions grew in 2019, especially in the PJM Interconnection, which serves the US 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% of total electricity generation, followed by 23% for coal and 20% for nuclear. New natural gas generation capacity additions have continued to displace coal-fired power plants; about 5% of the total existing US coal-fired capacity was retired in 2019.
Weather largely drives annual and monthly fluctuations in natural gas consumption. During the winter, US 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 US set a monthly record for US electric power sector consumption of 41.1 billion ft3/d in July 2019, then surpassed that level to reach 41.6 billion ft3/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.
