Early Development of Options and Interested Persons’ (IP) Process overview

The purpose of Interested Persons’ options is to increase the diversity of options considered within the Network Options Assessment (NOA) process through academic and industry participation. Options submitted through this process are required to be new and innovative and not currently assessed in NOA.

For us to consider an option, it must have demonstrable benefits, such as increasing the capability of a boundary whilst keeping costs as low as possible.

The early development of IP options will be an ongoing collaborative process between the provider, National Grid Electricity System Operator (NGESO) and the incumbent Transmission Owner (TO), as appropriate.

We will apply a screening stage to filter options from interested persons. We consider the following factors:

  • genuine network need
  • operability
  • practicality, for instance delivery date
  • costs
  • whether the same or similar option has been considered before and ruled out for good reason.
