Network Development Plan

info iconOn this page you'll find our updated 2022 Network Development Plan
(NDP) documents
 following stakeholder feedback. 
 

Sharing data is key to the efficiency of the energy system as we decarbonise to Net Zero.

It enables customers and stakeholders to assess market opportunities and participate in flexibility markets as well as promote network companies and key stakeholders to work together to facilitate efficient whole system planning and operation.

As a DNO we already publish network planning and development documents including Long Term Development Statements (LTDS) and Distribution Future Energy Scenarios (DFES).

The LTDS and DFES provide information and forecasts of our existing network and the availability of capacity in the short and long term respectively.

NDP

The aim of the Network Development Plan is to bridge this gap providing a medium term outlook to our stakeholders. It provides details on available network capacity to accommodate future demand and generation growth, as well as our planned interventions which increase network capacity.  


Our Network Development Plan structure

Our NDP is structured as summarised below and aims to provide stakeholders with transparency on our planned network developments and the resulting forecast network capacity headroom.

  • Executive Summary:
  • Network Development Report – this provides detailed information on our intervention plan
  • Network Capacity Headroom Report – demand and generation headroom at each substation to 2050 with planned interventions
  • Methodology Statement

Summary

A summary document to introduce our NDP, summarise the contents, and set out our consultation questions.

Part 1: Development report 

Contains detailed information on the interventions we plan that will increase capacity.

This includes non-load interventions which are not done to provide capacity but will increase capacity nonetheless (e.g. asset management interventions such as replacing an end-of-life transformer with a larger equivalent).

Part 2: Network capacity 

The indicative demand and generation capacity available at each primary substation (down to and including the HV busbar).

Forecasts are produced for every year for the first 10 years, and then for every five years after that out to 2050. These capacity forecasts must take account of known planned interventions which will increase capacity (Part 1).

Part 3: Methodology statement 

A document explaining how we have produced Parts 1 and 2. As the methodology is the same, this is a combined document for both our SP Distribution and SP Manweb licence areas. This includes a summary of the feedback we received.

Your feedback

We consulted upon our NDP documents between 16 March – 16 April 2022. We updated our NDP documents following stakeholder feedback and would like to thank our stakeholders for sharing their views with us.

To ensure that our plans and publications cover the needs and wants of our stakeholders, customers, and the communities we serve, we welcome ongoing feedback. Feedback can be emailed to RIIO_ED2@spenergynetworks.co.uk.
