Fewer rate cases mean better utility performance and growth, LBNL finds


The more often a utility takes a rate case to its regulators, the more its customers and performance are negatively impacted, according to new metrics. Traditional cost-of-service ratemaking (COSR) generally requires frequent rate cases and frequent rate cases are statistically associated with poorer utility productivity, according to a new report from Lawrence Berkeley National Laboratory (LBNL). More frequent rate cases are also statistically correlated with higher customer costs, the new metrics reveal.
