PARLIAMENTARY WRITTEN QUESTION
(24 April 2025)

To ask the Secretary of State for Energy Security and Net Zero, what estimate his Department has made of the proportion of Balancing Services Use of System charges that were caused by the management of renewable energy generation assets in each year since 2002.

Asked by:
Claire Coutinho (Conservative)

Balancing Services Use of System (BSUoS) charges are administered by the National Energy System Operator (NESO). The variable nature of renewable and low carbon intermittent sources of generation can require NESO to undertake additional grid balancing actions. The Government does not hold data apportioning overall balancing costs to these generation sources specifically. NESO publishes BSUoS charges here: Balancing Services Use of System (BSUoS) charges | National Energy System Operator
