We have "Time-of-Use" and Net Meter Energy rates (or words very close to that) through MCE, for our solar PV array, here in California, near San Francisco.
We have an old rate "schedule" which is closed to new customers, but think that mainly changes the time limits for on-peak / off-peak.
Rates vary enormously with season and time of day.
Winter was about 6 cents off-peak, 25 cents on peak.
Now on summer rates, about same off peak, 41 cents on peak.
With lots of hours of sun now, am "selling" (cutting my overall bill -- we cannot make money on this) during peak hours, charging car off-peak, naturally.
