The price for transport over the main grid is seasonal (which means that it varies from summer to winter for entry and exit points to interconnection points) and annual at storage transport interface points and exit points from the main grid.
The price depends on daily entry and exit capacities, expressed in MWh/day.

This price is made up of a price for transport over the regional grid and a delivery price. It corresponds to the cost of directing natural gas from the exit point on the main grid to the delivery point.
