What is a “time of use” (TOU) or interval meter and will I need one in order to participate in the customer choice program?
A TOU or interval meter is used for customers larger than most residential customers. The meter records how much power is being used at any given time (in kilowatts [kW], usually at 15-minute or half-hour intervals), as opposed to an energy use meter or kilowatt-hour (kWh) meter that measures how much energy has been used over a longer duration.
