Voltage costs

On this page, you’ll find outturn voltage costs for the regions detailed on a map.

To give greater insight on balancing decisions, the map provides outturn system costs for maintaining voltage levels on the network.

Maintaining the electricity system at the correct voltages enables safe and efficient power transfer across the network.

This requires the right balance of reactive power injection and absorption to be maintained in real time.

 

From 2nd March 2020, Voltage files will be published on our new National Grid ESO Data Portal.
