Reverse metering is not yet common in the
United States. If you own your own
wind turbine, there may still be times when you need more
electricity than it provides, in which case you will want to be hooked up to the
power grid so you can buy electicity from the
power company.
There may be other times when you produce more electricity than you need. Reverse metering would require the power company to buy this extra electricity at the same cost they charged when you bought it from them. In most cases this would permit them to create less pollution by making less use of other generating facilities.
Power companies object to reverse metering, and some of their claims may be worth considering in the interests of fairness, but at the very least reverse metering during periods of peak usage in places with peak usage power problems would be desirable. It would not require a major outlay, it could use the same metering equipment already in place.
