When Shippers Seek Release
Price caps, secondary markets, and the revolution in natural-gas portfolio management.

A majority of the commenting parties appear to favor a lifting of the price cap on capacity release in the secondary market. Some favor that only for short-term releases (less than one year’s duration). Still others (including the commission itself) have suggested a different type of price ceiling, using basis differentials from commonly published price indexes to put a value on released capacity.

“Using ‘basis differentials’ to value capacity has at its core a fatal circularity. Any particular ‘basis differential is the market-clearing value. … It makes no logical or practical sense to place a ceiling on a market price by reference to that price itself, for surely that would mean that there was no cap at all.”
