We both know I’ve lived in the deep north too!
The catch here is between social equity where electricity is supplied at the same price whereever you live in Australia,
The user pays, which in a commercially driven market allows users in the more expensive to supply north to be charged more. Of course establishing the real cost of supply to the far north remains an elusive goal.
We also have national competition policy, imposed by the Federal Govt long ago, with one desire. To dismantle state run enterprise in favour of private ownership. Whether in the end the other stated outcome of lower costs to consumers delivered through privatisation has come about remains highly contentious. Except for those invested in the private ownership?
Observing how the not quite ready for sale NBN project has treated us all equally (NOT) and delivered or not cheaper internet, perhaps the Deep North may be better of as is with Ergon for electricity the time being.
The downward trend in solar feedin tariffs may see all equal in the near future. Although those in the larger markets around Sydney, Melb, Bris may in the future see competition for customers deliver them the best deals.
