Planning, processing, and analyzing data for residential load studies
Well-designed electricity rate experiments can yield a large amount of quantitative information that should assist ratemaking and policy evaluation over a wide variety of circumstances. Specific examples from the Los Angeles Electricity Rate Study, a cooperative study by The Rand Corporation and the Los Angeles Department of Water and Power, illustrate the design of a rate experiment, the data processing needed, and the types of analysis that can be performed. In the end, the analyst must balance considerations of analytic costs and difficulty of interpretation against overly simplified analysis that may fail to address questions of central interest. In any case, the complexity and potential value of data from rate experiments raise a new level of challenge to traditional load research.
