Electricity Network Charges

All users of the GB electricity network pay to use it in some way. Generators use the network to transport their electricity to where it is needed. Demand users use the network to consume electricity when they need it.

Users of the network pay for use of the distribution and transmission network through four charges: 

  • Connection charge
  • Transmission Network Use of System charge (TNUoS)
  • Distribution Use of System charge (DUoS)
  • Balancing Services Use of System charge (BSUoS)
