Monthly average natural gas spot prices in the northwestern United States reached historic lows in 2025, as ample supply from Canada coincided with subdued regional demand for natural gas-fired electricity. At Northwest Sumas, a key pricing hub for natural gas in the U.S. Pacific Northwest, the daily spot price averaged $1.59 per million British thermal units (MMBtu) in 2025 through August and reached its lowest ever monthly average price of $0.56/MMBtu in June, according to data from Natural Gas Intelligence. The monthly average price for the first eight months of this year is the lowest for this period of any year since at least 1999, and it is about 17% lower than in this same period in 2024.
