America's Next Hot Import Might Be Record Energy Prices

It isn’t as though the U.S. hasn’t seen natural-gas prices this high before. They occasionally touched double digits before the shale boom, but that was during the winter, when every molecule was employed to keep the lights and heat on at home. Today the rest of the world might be in dire need of that gas, as well as America’s coal, just when a crunch arrives.

The U.S. is shipping out an order of magnitude more than it did even a few years ago. During the first half of the year, the U.S. has exported roughly 10% of its natural-gas production and continues to export at near full capacity. Before opening its first export terminal in the Lower 48 states in 2016, the U.S. exported less than 1% of its natural gas.

Coal exports are running high too. The U.S. exported 52.5% more coal in the second quarter than it did a year earlier, according to S&P Global Market Intelligence.

Europe and Asia are in worse shape, with Europe’s natural-gas inventories at a record low for September. Both regions are seeing benchmark prices soaring above $20 per MMBtu as they compete to attract liquefied natural gas cargoes.

Back at home, meanwhile, there is less coal for utilities to fall back on if the winter becomes harsh.

“We’ve heard of instances in the middle of the U.S. where power plants just can’t get the coal,” said Ethan Paterno, energy-markets expert at PA Consulting.

The Energy Information Administration expects U.S. power plant coal inventories to fall to 61.3 million short tons at the end of the fourth quarter, less than half last year’s levels. That is the lowest figure since at least 1997, according to Argus Media.

Thermal coal prices have been running hot alongside natural gas, partly because of strong export demand. In particular, China has been importing a lot more coal from the U.S. after banning the commodity’s import from Australia over a diplomatic spat. Newcastle Coal futures, among the more liquid benchmarks for thermal coal, are priced at $176 per ton, more than three times where they were a year earlier. High fuel prices are spilling into the U.S. electricity market. Analysis from EBW Analytics Group shows that electricity futures prices in all major power markets have surged over the past month. In the New England power market, forward power prices for January-February 2022 are already trading at nearly $150 per megawatt-hour, a significant jump from the $40 to 50 per MWh average seen during the winter in recent years, according to Mr. Paterno.

The cure for tight markets, of course, is high prices that spur more supply. But that is hardly a guarantee. There are capacity constraints at coal mines and limited available transportation, according to the EIA. Meanwhile, U.S. natural-gas producers who have pledged discipline to their shareholders aren’t likely to turn on the taps quickly. There were 34% fewer active natural-gas rigs than there were a year earlier as of Sept. 10, according to Baker Hughes.

The Industrial Energy Consumers of America, a trade group representing manufacturers, sent a letter to Energy Secretary Jennifer Granholm on Friday urging immediate action to reduce LNG exports so that the U.S. can stock up on enough natural gas before winter. The group said many manufacturers can no longer compete in the market if Henry Hub prices rise above $10 per MMBtu.

It is tough to tell exactly how much of the energy-price surges are due to the market “being on edge” and how much is fundamentally justified, said Christopher Louney, commodity strategist at RBC Capital Markets.

By the time we find out, it may be too late.
