This article is totally weird. To begin: “scheduled pipeline maintenance in Colorado reduced the system’s capacity to export out of the Rocky Mountain region”. So then what happened? “gas supplier Colorado Interstate Gas dropped the price” I have no idea why they did that. And there were buyers, in particular the city owned utility in Colorado Springs. Now this stuff “normally trades at $3 to $4” but the utility did pretty well: “2.6 cents”. Sadly most of their storage was already full; so they only managed to save a few million dollars. Too weird.
