Electricity SO Reform

The System Operator (SO) has a key role in planning and operating the electricity system. The role has already grown over recent years.

Through our Integrated Transmission and Regulation (ITPR) project, we have already made changes to the SO’s role to support more integrated and efficient planning and delivery of transmission investment. The SO has also taken on the role of the Electricity Market Reform (EMR) delivery body.

We think further change is needed to:

  1. The SO’s roles, to ensure it is well placed to both respond to and facilitate the transformation of the electricity system. These changes include both new roles for the SO and clarifying our expectations of how it will undertake existing roles.
  2. The structure of the SO, to mitigate conflicts of interest. We are proposing further separation of the SO within National Grid Group, with a level of independence and transparency to make industry confident in its impartiality.
