  • Modification Application

  • In some situations generators that have an agreement with National Grid may need to modify the existing agreement.

    To alter an existing agreement, customers will need to complete and submit a modification application to National Grid, pay the relevant application fee and submit the required technical data. This modification application is known as Exhibit I Modification Application.

    More information on the fee to be paid can be found in the document - Use of System Charges.

     If you would like to discuss the modification application or technical data required further, please contact your Customer Account Manager or a member of the Electricity Connections Team.
