There are two parts to the TIGF grid: the main grid and the regional grid.
The main grid provides a two-way link between the grids operated by adjacent transporters in France and Spain, enables access to the Lussagnet and Izaute storage sites and links in the Lacq production site.
The size of the regional grid depends on consumption needs within the area and enables gas to be taken from the main grid to directly connected consumers (generally high-consumption industrial sites) or to the distribution grids supplying consumers in urban areas.
