Our new legally separate company

The Electricity System Operator (ESO) is a legally separate business within the National Grid Group. 

The ESO became a legally separate entity within the National Grid Group on 1st April 2019.  Separating the ESO business from National Grid Electricity Transmission provides transparency in our decision-making and gives confidence that everything we do will promote competition and is ultimately for the benefit of consumers.
