US natural gas futures remained under downward pressure in midday trade on Monday due to a combination of strong supply and reduced demand.
The front-month Henry Hub contract and the continuous contract both fell 1.33% to $2.901 per million British thermal units.
Monday's losses extended last week's decline as the market struggled to find support despite softened expectations for continued summer cooling demand.
While demand is expected to be strong over the next seven days due to a heatwave in the northeast, Gelber & Associates said demand sentiment was damaged by cooler medium- and longer-term revisions across several major demand centers.
On Monday, regional transmission operator PJM Interconnection issued a "Hot Weather" alert for the entire region it serves for the July 14-17 window, citing high temperatures expected to cross 90 degrees Fahrenheit this week.
"A Hot Weather Alert is an established procedure PJM issues ahead of forecasted hot weather and/or high humidity to prepare transmission and generation personnel and facilities for expected increases in electricity demand, or load," PJM said.
NatGasWeather.com said national gas demand is expected to remain strong this week as a hot-to-very-hot ridge of high pressure dominates much of the US, including the northeast, with triple-digit highs. Overall, national demand is expected to remain elevated over the next seven days.
Gelber & Associates also noted that while the short-term forecast remains warmer overall, the concentration of heat after this week has shifted away from some of the most important cooling-demand regions, limiting the impact of hotter conditions elsewhere.
It also said that ongoing maintenance at Freeport LNG is a key factor weighing on demand. LNG feedgas demand was estimated at 17.7 billion cubic feet per day.
NRG Energy also cited reduced feedgas demand as a reason prices fell below the psychologically important $3/MMBtu level.
Gelber calculates production at 110 Bcf/d and Canadian imports at 5.8 Bcf/d, for a total of 115.8 Bcf/d, versus demand of roughly 110 Bcf/d, resulting in a surplus of around 6 Bcf/d and leaving overall supplies in a comfortable position.
