Kim from Denver. Want to share my initial demand review checklist because I see a lot of questions from newer members about where to start. Three questions I ask on every first bill review: what is the demand rate per kW, what is the billed demand, and does the billed demand match the interval data. Everything else follows from those three.
How I catch demand errors on the first bill review
Dave from Charlotte. Simple and useful. What do you do when you do not have interval data yet?
Kim again. Cross-reference the billed demand against the account's connected load. Request the utility's service order showing the installed load they used to size the service. If the billed demand is close to or above the installed load estimate that is a flag for investigation.
Maria from Austin. I also look at the demand-to-energy ratio. For a given type of business there is a reasonable range of peak demand relative to monthly energy consumption. A grocery store at 8 kW per 1,000 kWh is normal. Same store at 14 kW per 1,000 kWh is a flag.
Maria that ratio approach is something I have been developing informally. Do you have benchmarks by business type written down somewhere?
Maria again. I have a rough table I built from my own engagements. Not perfect but useful as a screening tool. Happy to share in a separate thread if there is interest.
Phil from Denver. Maria please do share those benchmarks. Even rough ranges would be very useful for initial screening.
