Wash. Admin. Code § 480-85-010 - Purpose
(1) The purpose of
these rules is to establish minimum filing requirements for any cost of service
study filed with the commission. These rules are designed to streamline,
improve, and promote efficiency in analyzing rate cases, clarity of
presentation, and ease of understanding. The minimum filing requirements will
allow for comparisons of cost of service studies.
(2) The cost of service study is one factor
among many the commission considers when determining rate spread and rate
design. The commission may also consider, as appropriate, such factors as
fairness, perceptions of equity, economic conditions in the service territory,
gradualism, and rate stability.
