The U.S. West Coast natural gas market is at the forefront of the energy transition, but regional natural gas prices are instead signaling the need for construction of newbuild gas pipeline capacity to the region. Without it, markets west of the Permian Basin have been hard-pressed to take advantage of the supply growth in West Texas and have struggled to consistently maintain adequate natural gas supplies for some time now. To make matters worse, last month, a segment of El Paso Natural Gas Pipeline (EPNG), a primary artery for moving Permian gas west, experienced a rupture, further tightening supplies. Today, we highlight the major market impacts and longer-term implications of the pipeline blast and subsequent flow restrictions.

Usually when we write about natural gas markets in the Western third of the U.S., we spotlight the Permian Basin and its Waha gas hub. The focus on Waha has been for good reason, as the last three years have been nothing if not exciting in the Permian’s primary gas market. The basin’s huge volume of associated gas production and Waha’s volatility and deeply negative basis — even negative absolute prices — have made the West Texas market eminently watchable. Though a flurry of new pipelines out of the Permian have helped tame the market somewhat recently and driven Waha to the point of positive basis on its best days, the markets west of the Permian are a different story. They have seen very little in the way of new gas infrastructure, and the constrained inbound pipeline capacity has recently driven prices in the Desert Southwest to some incredible premiums. In today’s blog, we take a look at the gas markets there.
