Grid Connections

These open source and commercial resources have been gathered and shared to give users access to a varied collection of grid connection tools. This includes maps, visuals as well as data processing/planning tools to make the process of connecting small domestic and larger commercial projects to the grid easier and more efficient. These tools are also essential in identifying areas of constraints or potential locations for planned projects.

ENTSO-E Transmission System Map

Transmission – Europe

This map is a comprehensive illustration of the transmission system network operated by members of the European Network of Transmission System Operators. In general the map shows all transmission lines designed for 220kV voltage and higher and generation stations with net generation capacity of more than 100MW.

Transmission Network Capacity Map

Distribution – Midlands, South-West England, South Wales

Map provides an indication of the networks capability to connect large-scale developments to major substations. The colour gradings are intended to guide the user to areas of the network where a connection is more likely to be achieved without significant reinforcement.

ConnectNow Research Assistant

Transmission – England and Wales

Map with potential demand connections, where location is chosen and the tool generates estimated distance from substation, as well as generation rate.
Designed to provide connection information and investigate options, see connection timeframes, estimate cost profiles, enquire directly to National Grid Elec Transmission for connection. Helps to understand potential connection options, submit enquiries ahead of applying for connection. Gives different charges and options. Not only limited to the area that they are the energy network provider for.
