Are you sure? If you are on the 66c/khw. then you should be sending 100% of your power to the grid, as it should be gross metering. You then buy back everything you use from your electricity company. You might have a Nett invoice (what you feed vs what you consume) that indicates a cost difference of 70% of the value.
