Capacity gives shippers the right to flow gas on and off the National Transmission System (NTS), and so capacity is often also referred to as ‘rights’ or ‘entitlements’. A shipper needs to buy one unit of capacity in order to flow one unit of energy on or off the system. This is known as the ‘ticket to ride’ principle. Units for both capacity and energy are in kWh/day.
