Yep, I've heard a number of 3-4GW/million in the past, how much industry though would be a huge factor in the +/- of that average.
Just taking a rough number from the
current Alberta generation, for a population of 3.6 million the demand is currently sitting at 8.1 GW for the entire province, granted it is a Sunday afternoon. I believe our record for demand is around 9.7GW a couple years ago. So we're currently using 2.25GW/million and our record was around 2.7GW/million
