Discussions may have been prudent on the HV system as we have a significant network at 110kv.
I never realized that N.I. used anything other than the standard British transmission and distribution voltages. Presumably this was due to influence from south of the border?
For those not familiar with the British system, the standard levels are 400, 275, 132, 66, 33, and 11kV. There are also a few old 6.6kV systems still in use in a few areas.
