Demand users who are connected to the transmission network on a boundary between different demand zones will pay an average Transmission Network Use of System (TNUoS) charge, under changes approved by Ofgem. A code modification to the Connection and Use of System Code, approved by the regulator Ofgem, was needed due to a number of demand users being expected to connect at a boundary point between multiple distribution network operators (DNOs) during the 2022/23 charging year.
