National Grid Electricity Transmission

We have awarded funding to four National Grid Electricity Transmission projects.

RICA - 2020

The project aims to develop a method of using insulated crossarms (ICA) to increase the voltage rating on existing 275kV overhead line towers to 400kV. This will allow increased power to be transmitted on existing routes without replacing the towers

Transmission & Distribution Interface (TDI) 2.0 (National Grid Electricity Transmission) - 2016

TDI 2.0 will demonstrate how services traditionally offered by transmission-connected generation to the SO (such as voltage stability and thermal capacity) can be provided by distribution-connected energy resources. The distribution company will effectively act as ‘gatekeeper’ in providing some of these services to the SO. The project will also examine how these new services interact with the existing commercial arrangements.

Off-grid Substation Environment for the Acceleration of Innovation Technologies (OSEAIT) - 2015

This project aims to modify an existing 400kV electricity substation into a field trial facility to host electricity related innovation projects in a live substation environment.  

Enhanced Frequency Control Capability - 2014

This project will develop and demonstrate an innovative package of tools to enhance the capability to deliver system frequency control.
