The natural gas procurement market was officially deregulated in February of 1991 with Commission Decision (D.91-02-040).  This decision followed a pilot aggregation programs established in November of 1990 by D.90-11-061.  Decision (D.91-02-040) offered core gas customers the opportunity to aggregate their loads in order to participate in competitive gas markets.  The decision to allow customers to choose where to buy their gas from was seen as aligned with the Commission's efforts to limit utility presence in gas procurement.  Later, in 1995, the Commission ordered the unbundling of transportation rates from procurement rates.  This decision sought to reduce customer CTA customer liability for interstate capacity, lowering CTA customer prices and enabling core aggregators to better compete with utilities and weaken monopolies.
