        normal consumption patterns of those demand-side resources in 
        response to--
                    ``(A) changes in the price of electricity over 
                time; or

                electricity use--

                        prices; or

                        reliability is jeopardized.
            ``(2) Demand response capabilities.--The term `demand 
        response capabilities' means the hardware or software, 
        including any combination of hardware and software, that is 
        necessary to participate in a demand response program, as 
        determined by the Secretary.
    ``(b) Requirements.--
            ``(1) Initial requirements.--

                water heaters of different storage capacities.
