I can't remember Greg, apologies, it was in 2005. However, it was the
culmination of examining data from the various participants in the
transmission network over three years for the entire grid on the Eastern
Seabord of Au and taking the lowest aggregate number.
The majority of the data was from the Nemmco archives and with obvious
differences in aerial versus submarine. We concentrated on only the
aerial numbers as being the majority of power distribution across long
distances in Au.
As a sanity check I remember we cross referenced it with some data from
France and Germany (Alsace) and discovered many parallels.
