The potential growth rate, location and size of new generation raises a number of challenges in terms of grid connections. This has resulted in the requirement to consider a coordinated (or integrated) design of the offshore and onshore transmission system. This page includes information on:

·          The Offshore Transmission Network Feasibility Study

·          Charging

Charging

 

Our initial thoughts on the areas of the electricity charging regime that may benefit from changes to facilitate the development of an integrated onshore-offshore transmission network are available below, considering:

 

·          The challenges for the existing charging arrangements

·          Areas requiring development to accommodate integrated onshore-offshore

·          Principles that should be applied

View the Integrated charging note

Further work on charging for integrated onshore - offshore transmission has been undertaken in conjunction with industry members through an informal working group.  The report below outlines the results of those discussions and requests feedback from interested parties on the work undertaken so far.

The Offshore Transmission Network Feasibility Study: A coordinated offshore approach

In order to investigate the feasibility of an integrated offshore and onshore transmission approach National Grid and The Crown Estate worked together on the Offshore Transmission Network Feasibility Study which is available below.
