KwH Usage from Utility

[dvcraven0522!]

Got this printout from the utility for client who wants to add EV charging stations to condo units. I do not know how to convert this numbers to a load data on the services. Not sure either of their is enough info here.

Thanks

You can't convert usage to load.

Ok - I do I get demand loads from the utility other than be placing a demand meter on the service for 30 days.

First ask the utility, or have the customer do so. For residential condos they probably do not have 'demand' data (typically based on 5 minute or 15 minute intervals), but yiu can ask. If they provide 'Greenbutton' data you may be able to get 60 minute data. See here for a discussion of using 60 minute data conservatively. There have been a number of discussions on code section 220.87 that debate what you can do with such data if you have it, try doing a search.

Otherwise you'll indeed have to install metering or use another load calc option.

I agree in this case the document does not have what is needed. People should just be aware that some utilities do not use the word "demand" and instead call it "KW usage", so keep that in mind when looking at utility bills.
