National Grid Electricty: Transmission

National Grid is the sole electricity transmitter in both England and Wales. It owns and operates an extremely large transmission network, consisting of 7,200km of overhead line, 690km of underground cable and 337 substations. This transmission network delivers to the electricty to the distribution networks across England and Wales, largely contributing to the delivery of electricity to the approximately 58 million people living within the two countries.

What's a substation?A substation is a place where step down transformers reduce high voltage electricy from the transmission lines to lower voltage electricty, making the electricity safe to be transferred to the distribution network and into homes and businesses.

National Grid do not produce any of their own gas; they receive it from the gas producers at each entry point of their transmission network. This network is indirectly paid for by the end-user/consumer; part of the gas price you are charged by your gas provider is paid to the transmission and distribution networks.
