For a large utility, Brattle experts provided analysis and testimony in support of the utility’s proposal to offer new rate choices to its residential customers. In addition to the standard rate, the utility proposed to offer two new rate options: a rate with an increased fixed charge and a lower volumetric charge, and a three-part rate with a demand charge. Our work included bill impact analysis on the cost and risk shifting from the new structures across different types of customers within the same rate class, simulations of the likely adoption, and revenue impacts of the various rate options.
