Whilst the ACCC is looking at the supermarkets, maybe they should look at the power companies, look at your feed in tariff in comparison to your grid price per Kw and I’d guess most are being stung by a markup of 500 to 700% of what you receive. Power companies will bleat about network up keep etc, but don’t we have the same with maintaining our own solar panels, wind generators, batteries, up graded switchboards etc.
