Storage Capacity

Rough is a seasonal storage facility - value is derived from injecting gas in the summer when prices are low and withdrawing gas on the highest priced days in Dec/Q1

Rough’s flexibility enables customers to change nominations at short notice to take advantage of attractive spot and forward price changes. Rough capacity is priced based on the difference between the forward Q1 and Summer.
