I believe the primary reasons for GPS receivers for the power industry
is power line fault location. They use time tagging to measure
disturbances to locate a fault and it's accuracy directly determines its
resolution.

Interestingly, one of the markets that Symmetricom/TrueTime/Datum sells
into is GPS disciplined receivers used for power control. Power
transmission is managed by controlling relative phases in the system,
not to mention things like synchronizing generators.
