US natural gas prices in 2016 averaged $2.49 per million British thermal units (MMBtu) at the national benchmark Henry Hub, the lowest annual average price since 1999.
The monthly average price fell below $2.00/MMBtu from Feb. through May, but later increased, ending the year at an average of $3.58/MMBtu in Dec.
Warmer-than-normal temperatures for most of the year and changing natural gas demand were the main drivers of natural gas prices in 2016.
