Its imprint is being felt in the US gas futures market, which in November experienced its longest stretch of extreme volatility in nine years due to demand, low inventories and unseasonably cold US weather.
LNG currently accounts for just a small amount of overall domestic gas demand. But as the country opens more facilities for export to meet growing needs abroad, analysts said more ups and downs in prices are expected.
"As LNG exports increase, so will future gas prices," said Tom DiCapua, managing director of wholesale energy services at Con Edison Energy, a provider of energy management services, including the purchase of gas, for power plants owned by several companies.
Prices at the US Henry Hub benchmark in Louisiana hit $4.929 per million British thermal units (mmBtu) in November - their highest in four-and-a-half years. That was also well above the five-year average from 2013-17 of $3.25/mmBtu.
The United States is on track to export about a trillion cubic feet of LNG by year-end, or about 3 percent of overall US gas demand in 2018.
But LNG exports are expected to rise to 5 percent of overall US gas demand in 2019 and to 10 percent in 2024, according to the US Energy Information Administration (EIA), boosting LNG's potential to affect prices.
"LNG exports will be one of the most bullish demand factors for US natural gas prices over the coming two years, when several terminals are set to come online," Raymond James analyst Muhammed Ghulam said.
There are three LNG export terminals presently in operation in the United States. Those include Corpus Christi in Texas, which shipped its first cargo in December. Three more terminals are expected to enter service in 2019, boosting US LNG export capacity to 8.9 billion cubic feet per day (bcfd) of gas, making it third largest in the world behind Australia and Qatar.
