Many analysts are bullish on US coal production this summer due to comparatively high natural gas prices and utilities’ low coal stockpiles which power companies like to have on hand for baseload requirements. Severely depleted gas inventories that need refilling before next winter could help keep gas prices elevated, but coal companies are reluctant to increase output due to rail shipment constraints and the generally negative longer-term market outlook given the expectation for continued coal plant retirements and increasingly stringent coal-burning regulations. “With natural gas storage at multiyear lows entering injection season, we expect the need to refill storage to be directly at odds with peak demand from the gas-fired generating fleet during the summer,” Scott wrote in comments reported by SNL Financial. “Should weather be normal or hotter than normal, we would expect to see further improvements in coal burns and inventory levels, which would likely provide upward pressure for 2015 tonnage still open.” [Casper Star-Tribune]
