Re: Previous DCC Employee
Probably because they can already track down power theft pretty accurately.
All the substations have accurate metering, and they know the expected load given what's attached to it. It's not rocket science to spot a substation that's supplying more than the expected load.
While in theory more accurate metering might help, it'd take extremely high penetration >90% or more before it could begin to offer anything they don't already have.
