Can smart thermostats optimize heat pumps under TOU rates in Charleston?
Yes. Smart thermostats pre-cool or pre-heat homes in Charleston during cheaper off-peak hours and coast through expensive 4 PM–9 PM peak periods, reducing utility costs without sacrificing comfort.
How much can scheduling EV charging into off-peak hours save in Charleston?

What hardware is required for dynamic pricing in Charleston?
An automated AMI smart meter installed by your local electric utility in Charleston is required to measure interval electricity consumption on a 15-minute or hourly basis.
How does rooftop solar interact with TOU dynamic tariffs in Charleston?
Under modern TOU net billing tariffs in Charleston, midday solar exports receive lower wholesale credits. Pairing solar with battery storage prevents exporting at low rates and covers expensive evening peaks.
