Cost Rate Studies

A Cost of Service Analysis (COSA) is a study that confirms the utility’s revenue requirement and its equitable allocation across the various customer classes of service. Output from the COSA was designed to facilitate the development of rate designs—that is, the electricity rates for the various classes of customers (residential, industrial, small commercial, etc.). 

An in-depth COSA was performed by EES Consulting in 2015 and updated in 2016.
