That depends on what your KW charges are as well as the cost of the unit. Remember, you will pay the same kWh charges because you aren't getting free electricity. You are just reducing the demand, your consumption remains the same. If your demand charges are only $10/month then the payback may be way too low. Think of this as snake oil in a way. Fundamentally, it works to reduce demand but unless you're paying seriously high demand charges it won't pay back in your lifetime.
edit for your edit. If the incentive nearly pays for it then you are not really losing anything. The utilities will offer incentives to customers to reduce demand. This helps utilities like SRP keep from building higher capacity plants.
