A. Introduction
The load profiling workshop had several objectives. In addition to developing statistical load profile methodologies, the workshop addressed a process for updating and revising statistical load profiles, ways in which load profiles can be made more accurate, and whether load profiles should be developed for certain kinds of customers whose maximum demand is greater than or equal to 20 kW but less than 50 kW.
D.97-05-040 permits customers with maximum demands of less than 20 kW to participate in direct access through load profiling. The UDCs proposed at the workshop that the Commission adopt the UDCs' approach for developing and implementing load profiles as an interim measure. The UDCs propose to create load profiles in existing rate categories that are based on daily load shapes. The load shapes would be derived from the UDCs' existing systems, procedures, load research meters, and samples. The UDCs propose that the 20 kW threshold be determined using existing rate schedule breakpoints. When existing rate breakpoints are not aligned with the 20 kW threshold, in most cases, the UDCs propose to screen the 1996 billing data for demand of less than 20 kW.
The Workshop Report states that this approach builds on proven techniques borrowed from current ratemaking practices, and that the implementation of this proposal is straightforward, cost-effective, and achievable by January1, 1998.
The UDCs' proposal calls for a single load profile to be used for all customers in a rate category, regardless of whether the customer takes service from the UDC or a retailer. Thus, the UDCs would create load profiles for the existing rate categories, and provide this information to all retailers. If a customer chooses another retailer, then the same load profile would still apply to this customer.
The Workshop Report indicates that some of the workshop participants disagree with various aspects of the UDCs' proposal. They believe that the Commission should direct the UDCs to modify their proposed implementation of load profiling by January1, 1998, or as soon as practical thereafter.
