Frustrating situation with an APS client in Mesa. Found $22,000 in annual savings through rate schedule change and load factor improvements. Client's internal engineer is questioning my demand calculations and wants to see "peer-reviewed methodology." How do you handle technically sophisticated clients who challenge your analysis?
Handling clients who question your methodology
I always include detailed calculation methodology in appendices for exactly this reason. Show your formulas, data sources, and assumptions. If they want to verify, give them everything they need.
Had similar pushback from an engineering firm in Alabama Power territory. I invited them to a working session where we went through the analysis step-by-step. Turned skeptic into advocate once he understood the approach.
Sometimes engineers just want to understand the process. I reference industry standards like IEEE billing analysis guidelines and ASHRAE demand calculation methods. Gives academic credibility to practical work.
Also helpful to reference utility tariff language directly. When you quote the exact rate schedule terms and calculation methods, it's hard to argue with the utility's own documentation.
Don't take it personally. Engineers are trained to question everything. Treat it as quality control and be willing to explain every step. Usually they're just doing due diligence.
Exactly Carol. I've found that detailed methodology sections actually help with all clients, not just engineers. Shows professionalism and thoroughness even if most people skip reading them.
