Network Headroom Report

Project Overview

This dataset indicates the amount of unused network capacity for demand (Demand Headroom) over time on our Grid and Primary substations. It shows where we may need to further reinforce our substations or procure flexibility services beyond our existing plans, if the energy system develops as indicated in each of our scenarios. It is an illustrative data set for consultation on the form and scope of the report, and is based on our 2019/20 peak demand and capacity information, but does not factor in generation volumes.

See the guidance and consultation document in ‘Attachments’ and We will update the headroom report in 2022, as part of our ‘Network Development Plan’. The next update consistent with the new Long Term Development Statement to be published at the end of November 2021. We will also add generation headrooms to the Open Data Portal in 2022. Our example generation headrooms have not been included so far as they are based on an initial simple methodology.
