A lot of utilities either do a straight swap kWh for kWh or where time of use pricing is in effect they only buy electricity at the lowest tier price.
What they are trying to prevent is people installing a battery system, charging it at night on cheap utility power and then selling it back to the utility at peak rate.
For people with residential solar peak production should be at the same time as peak electrical pricing.
