Distribution Future Energy Scenarios Network Scenario Headroom Report (DFES NSHR)

Our Distributed Future Energy Scenarios Network Scenario Headroom Report (DFES NSHR) is part of our Network Development Plan (NDP). The April 2024 DFES NSHR dataset uses our 2023 network, loading and scenario data, with the Long Term Development Statement November 2023 as baseline.

For further information on the NDP and the methodology to produce the DFES NSHR dataset please see Long Term Development Statement and Network Development Plan Landing Page

The DFES NSHR indicates the amount of unused network capacity for demand and generation over time to 2050 on our Bulk Supply Point 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. Since the report indicates unused substation capacity in each year, please note unused capacity may be contractually committed to customers. Those seeking connection should contact our connections gateway to understand the latest view of available capacity.

The headroom tables show firm capacity - more capacity may be available for customers on a non-firm, flexible or curtailable connection. 

The demand headroom tables reflect our latest firm capacity figures for demand, consistent with the May 2024 LTDS.

As noted in the methodology, unused substation capacity (headroom) is indicative and may be already contractually-committed to specific customers.
