1 - The number of physical entry points to the transmission system i.e. places of the gaseous fuel delivery with specified physical location. This number includes gas import, gas off-take from the underground gas storage, gas delivery from producing fileds and production (mixing facilities).

2 - The number of physical exit points from the transmission system i.e. places of the gaseous fuel off-take with specified physical location. This number includes transmission to exit points at the point of interconnection with a distribution area and distribution network not being gas distribution area, delivery to the underground gas storage, export and final customers.

3 - The provided amount of gas transmitted includes transmission of low-methane natural gas (L) converted into high-methane natural gas (E). The amount of transmitted gas in volume units (m3) is just approximated value.

4 - The provided amount of gas transmitted includes transmission to underground gas storage, transmission of low-methane natural gas (L) converted into high-methane natural gas (E). The amount of transmitted gas in volume units (m3) is just approximated value.
