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 28 November 2025), 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 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 worked together to ensure data accuracy and consistency.

### 方法学说明
站点功能位置（Functional Locations, FLOCs）用于将变压器所属变电站与英国电力网络（UK Power Networks）的活跃电网及主站点的关键特征相关联。为便于参考，本数据集已添加ID字段以标识行号。

### 质量控制声明
本次数据采用的质量控制措施包括：
1. 仅将特征与已确认的功能位置进行匹配的验证步骤；
2. 对数据不一致性开展人工复核与修正；
3. 采用额外验证步骤以确保方法学的准确性。

### 数据保障声明
开放数据团队（Open Data Team）与网络洞察团队（Network Insights Team）携手合作，以确保数据的准确性与一致性。
