Overview

The Long Term Development statements provide information for anyone connecting to our distribution system at extra high voltage (EHV) level (including HV busbar of primary substations). It is designed to help to identify and evaluate opportunities for entering into arrangements with us relating to use of system or connection. Our statements include the following: network data; the likely development of our distribution system; plans for modifying the distribution system; and identification of parts of the distribution system that are likely to reach capacity limit in the next years. A long term development statement is available for each of our distribution network areas in central southern England and northern Scotland. Each statement has two sections, a summary (Part 1) and a detailed section (Part 2) both of which are available for download below.
