(a) Application. The provisions of this section are applicable to residential electric water heaters and electric central air conditioners.
(b) Peak Load Cycling Program. The utility shall carry out a peak load cycling program, if such a program has been found to be cost effective for the utility. Under this program, the utility shall offer to install remote load switches in those identified residences in the utility's service area which contain electric water heaters or central air conditioners. The switches shall allow the utility to cycle any of these electric appliances.
(c) Program Implementation. The utility's peak load cycling program shall consist of three phases as follows:
(1) Peak Load Cycling Plan Development Phase. The purpose of this phase is to allow the utility to develop a Peak Load Cycling Plan which will accomplish the program goals set forth in subsection (d) below. The requirements for the plan are specified in subsection (e) below. The utility may conduct experimental Peak Load Cycling Programs prior to approval of its Peak Load Cycling Plan by the Commission. Any such program shall, to the maximum extent feasible, be consistent with the provisions of the Peak Load Cycling Plan which is being developed by the utility or which has been submitted pursuant to Section 1621(d). Any expenditure which the utility makes in connection with any such experimental program prior to the approval of its Peak Load Cycling Plan shall be subject to the approval of the utility's rate-approving body.
(2) Testing and Evaluation Phase. The purpose of this phase is to allow the utility to conduct detailed testing and evaluation of alternative technologies for peak load cycling, of customer acceptance of peak load cycling, and of the benefits of peak load cycling in terms of reduced peak demand, at a low level of implementation. The testing and evaluation phase shall commence as soon as the Commission has approved the utility's Peak Load Cycling Plan and the utility's rate-approving body has approved program-related tariffs and a method for recovering the cost of the program. Once this phase has commenced, it shall last for 28 months.
(3) Systemwide Implementation Phase. The purpose of this phase is to achieve the maximum feasible level of system load reduction in the utility's peak load cycling program. This phase shall commence after the Commission takes action pursuant to subsection (h) below.

While the utility is carrying out these phases of its peak load cycling program, it shall cooperate on an ongoing basis with the Commission Staff in evaluating the relative merits of alternative hardware systems, in determining the optimal approaches for obtaining maximum customer participation in peak load cycling programs, and in improving and refining methodologies for calculating the cost-effectiveness of peak load cycling programs and other load management programs.

(d) Program Goal. The utility's peak load cycling program shall be designed and carried out t achieve the following goals:
(1) By the end of the testing and evaluation phase, the utility shall have installed remote load switches on approximately 8 percent of the total of all identified residential central air conditioners in the utility's service area, except that a utility may install switches on a greater or lesser percentage of those appliances, if, in its peak load cycling plan, the utility provides information which demonstrates that a program goal of more or less than eight percent will be more cost-effective for the utility to implement, and if the Commission approves the utility's plan. The utility shall maintain a level of implementation according to an approved Peak Load Cycling Plan.
(2) By the end of the testing and evaluation phase, the utility shall have installed remote load switches on a sufficient number of residential electric water heaters in the utility's service area to allow the Commission to determine whether it would be cost-effective for the utility to implement a peak load cycling program for residential electric water heaters on a system-wide basis. The utility shall indicate the number of residential electric water heaters which will be subject to this experimental program in its peak load cycling plan as well as the test program methodology for determining cost effectiveness. In carrying out its peak load cycling program for such appliances, the utility shall maintain the level of implementation set forth in its peak load cycling plan.
(e) Peak Load Cycling Plan. No later than eight months after this article becomes effective, the utility shall submit a Peak Load Cycling Plan.
