    Customer procurement connection model (MP/IP only)

    To allow you further ownership of the delivery of the connection we can facilitate a self procurement model that offers the same ownership and responsibility as the Minimum connection model with the additional activity of you undertaking the procurement of the ROV and RTU.

    These items, after commissioning will be owned and operated by National Grid, subject to meeting required specifications/designs.
