Our bills were getting up around the $600 mark. We recently installed a 1kw solar power system on the house and still haven't got the updated meter that will give us 60c per kW/h produced. Our last bill went down a smidge but everyone else has been complaining about how much their bills have gone up. It looks as though the solar power will take a bit of sting out of the power bills at least. Winter might be a bit different with less daylight hours and solar power production reduced.
