A Power Company Electrical Engineer gave me the following equation to convert KWhrs to KW demand:
KWhrs/Number of hours per month/Load Factor

Just for practice I've reviewed several power consumption reports for our buildings and when I plug in 40% load factor it seems rather accurate. I use it as my "default" load factor figure.

My very limited knowledge of load factor is: The percentage of load during demand.

Just for an example most residential electric meters are not of the demand type.
At times it would be nice to know the approximate, converted KW demand.
Do you think using my "default" Load Factor figure of .40 is a good idea?

Sounds good. I'm gonna try it out here and there [the 0.4 load factor].

Have a few various Residentials to test this on. Each have different electric loads which are used randomly.

I'll take some Digital shots of various Commercial KWH Meters with the Demand Scale, plus chart the data. Most of the Meters have no "seals" on the reset crank for the Demand reading, so this test is easy. Hope it doesn't get the PoCo guys mad [aka Illegal to reset Demand Data!]. If this is a No-No, please let me know before my next address becomes:

Scott-

Please be sure to post your findings. I'd really like to know what you came up with.
