EC Enterprise: What are EnergyCAP "Best Practices" for demand tracking

Question: What are EnergyCAP best practices for demand tracking?
Answer: We don't have a single best practice recommendation; it depends upon the reporting and analysis needs of the user. Some clients prefer simple while others prefer detailed.
Simple: The user has no need for time-consuming detailed demand tracking because of (1) low overall demand cost or (2) lack of interest in demand analysis and reporting. We recommend a single Billed Demand line item be tracked on electric templates. Usage and demand cost (if itemized on bills) can be tracked as a single Total Cost line item. Template KW_01 is a good choice.
Detailed: The user accepts the trade-off of spending more time/expense on more detailed and lengthy bill entry templates in order to collect more demand information. Templates KW_02 and above provide a number of options, depending upon such factors as:
- Do bills show both Billed Demand and Actual (metered or registered) Demand?
- Are electric accounts on time-of-use rates (On Peak, Off Peak, etc)?
- Are Reactive Demand and Power Factor costs itemized on the bill and important elements of total cost?
- Do bills itemize cost for each line item, or are costs summarized?
- Are electric rates based on hours used in which case demand is very important but not evident as a cost item?
- Do rates have ratchets which are indicated by billed demand in excess of actual demand?
- Is more than 25% of total cost attributable to demand charges?
Each item above requires a thorough understanding of fundamentals of electric service, electric bills and especially electric rate schedules. A good place to learn more is www.FreeEnergyManagerTools.com. The BGE and Schneider links offer valuable, and free, training resources.
