Long Term Development Statement (LTDS) Table 2b Transformer Data - 3W

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 2b from our current LTDS report (published 29 November 2024), showing the Transformer information for three winding (1x High Voltage, 2x Low Voltage) transformers associated to each Grid and Primary substation where applicable.

Methodological Approach

Site Functional Locations (FLOCs) are used to associate the Substation which the transformer is located 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 correct of data inconsistencies

Use of additional verification steps to ensure accuracy in the methodology

Assurance Statement

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