Long Term Development Statement (LTDS) Table 4b Fault level data - Earth

Introduction

The Long Term Development Statements (LTDS) report on a 0-5 year period, describing a forecast of load on the network and envisioned network developments. The LTDS is published at the end of May and November each year.

This is Table 4b from our current LTDS report (published 29 November 2024), showing the earth fault level at each Grid and Primary substation. More information and full reports are available from the landing page below:

Methodological Approach

• Site Functional Locations (FLOCs) are used to associate the Substation to Key characteristics of active Grid and Primary sites — UK Power Networks
• ID field added to identify row number for reference purposes

Quality Control Statement

Quality Control Measures include:

• Verification steps to match features only with confirmed functional locations.
• Manual review and correction of data inconsistencies.
• Use of additional verification steps to ensure accuracy in the methodology.

Assurance Statement

The Open Data Team and Network Insights Team together ensure data accuracy and consistency.
