Debating training methodology with a colleague and wanted to get input from the group. When teaching new auditors how to interpret utility tariffs, do you start with simple residential rate schedules and work up to complex industrial rates, or throw them into the deep end with complicated commercial schedules from day one? Eversource Connecticut has some pretty straightforward residential TOU rates but their Schedule LM for large manufacturing gets incredibly complex with multiple demand components and seasonal variations. I've been starting simple but wondering if that actually slows down the learning process.
Teaching tariff interpretation - start with simple or complex rates?
Vince, I've tried both approaches and definitely lean toward starting simple. The foundational concepts of energy vs demand charges, time-of-use periods, and seasonal adjustments need to be solid before tackling complex industrial rates. Georgia Power's Schedule PL has enough moving parts that junior auditors get overwhelmed if that's their first exposure to tariff analysis. Better to build confidence with straightforward calculations before introducing ratchet provisions and transformer loss adjustments. My two cents anyway.
I actually go straight to complex rates now after years of trying the gradual approach. Here's why - junior auditors working for consulting firms are going to be analyzing large commercial and industrial accounts anyway. Starting with residential rates creates habits that don't translate well to industrial billing analysis. Entergy Louisiana's Schedule LGS is complicated but if they can master that, everything else seems easy by comparison. Takes longer initially but they become better auditors faster in my experience.
Both approaches have merit but I think it depends on the person's technical background. Engineering graduates can probably handle complex rates from the start, but business majors or career changers might need the progressive approach. CPS Energy here in Corpus Christi has some moderately complex commercial schedules that work well as intermediate steps between simple residential and complex industrial rates. Maybe the real answer is customizing the training path based on each junior auditor's background and learning style.
