What is Time-of-Use (TOU) metering?
A TOU rate plan from APS bases the price you pay for electricity on the time of day and the time of year you use energy. With TOU, you typically pay more for electricity during peak hours (9 AM to 9 PM weekdays) in the summer. You pay less during all other hours (off-peak, partial-peak) and in the winter. TOU can be very beneficial to solar PV owners since, under the net metering laws, the power company must credit you at retail rates for any excess power you produce. So, if you can “sell” your excess electricity at peak rates and buy it back at off-peak rates, your PV system will have a greater impact on lowering your energy costs.
