U.S. Natural Gas Benchmark Falls 3.1% to $3.011

Natural gas futures settled at $3.011 per mmBtu on Sept. 29, down 3.1%, Wall Street Journal market data show. Henry Hub is the U.S. benchmark price point; mmBtu means million British thermal units, the standard gas unit. Lower near-term prices could ease winter heating and power bills, but futures show expectations, not guaranteed savings.
