ConnectNow Research Assistant

Our digital research functionality

Our digital ambition places our customers at the heart of everything we do, and our Connect Now tools have been designed to help research and manage connections to the Electricity Transmission system in England and Wales.

Our Research Assistant tool helps you to understand potential connection options and submit enquiries to us ahead of applying for a connection. Once you have applied for a connection to our network, the Connect Now portal enables you to track your project's progress. Further details are explained below.
