We have a responsibility to keep the National Transmission System (NTS) within safe operating limits. This includes us acting as a balancer by taking energy balancing trades from the On The Day Commodity Market (OCM) and matching it with supply and demand needs. On these pages you will find out more about how we are balancing the NTS.

On this page we provide an overview of the commercial elements of GB gas balancing activity and feature our end-to-end balancing guide which outlines the commercial elements of GB gas balancing activity.
