Most utilities suspect their rates haven't kept up with costs — what they don't have is a clear picture of the gap. Cost of Service is a screening tool, not a rate study: it pulls your real cost and revenue data to answer one question — is your published rate structure still covering cost, or is it time to call a rate consultant?
This is a screening tool, not a rate study. It tells you whether a formal rate case is warranted — it does not produce a defensible rate schedule. Formal rate studies require a certified rate consultant. LRMS operates on your published rate structure; off-schedule arrangements (reduced rates for schools, grandfathered customers, contract-ops side deals) are not reflected and need to be overlaid manually.
