A giant flaw in Texas blackouts: It cut power to gas supplies

When the Texas power grid was on the brink of collapse and its operator plunged thousands into darkness, it didn’t make an exception for the oil and gas field.

Power was, unsurprisingly, diverted to hospitals and nursing homes. Ercot, as the grid manager is known, was staving off utter catastrophe, its chief executive later said.

But leaving shale fields like the Permian Basin dark had an unintended consequence. Producers who depend on electricity to power their operations were left with no way to pump natural gas. And that gas was needed more than ever to generate electricity.
