Renewable Energy: Fees and Charges

Asked by Claire CoutinhoConservativeDepartment for Energy Security and Net ZeroTabled Answered 2 May 2025UIN 47813

The question

To ask the Secretary of State for Energy Security and Net Zero, what estimate his Department has made of the proportion of Transmission Network Use of System charges that were caused by the (a) expansion and (b) reinforcement required for renewable energy in each year since 2002.

Answered by Michael Shanks

The Government does not hold this information. Transmission Network Use of System (TNUoS) charges recover the cost of installing and maintaining the high-voltage transmission network, which are paid for by electricity suppliers and transmission-connected generators and administered by the National Energy System Operator (NESO). The charges reflect the costs imposed on the network by generators and demand in different locations. NESO publishes annual TNUoS charges here: https://www.neso.energy/industry-information/charging/tnuos-charges#TNUOS-tariffs-and-notifications-of-changes.
