  • Capacity

    • Capacity gives shippers the entitlement 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 1 unit of capacity in order to flow 1 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
