Submetering the Electricity

[Kenneth Garrett]

I have a four unit building with one meter for the building.  I am looking at submetering the elecric for each unit.  Each unit has its own panel in the furnace area plus a common panel.  The idea would be to submeter each panel that serves each unit.  We would have to send individual bills to each tenant after we calculate the cost from the bill (dollar per kw). 

Any advice on anyone who has done this from billing to the actual submetering equipment.  Pros and cons.  I know there are companies that will provide the billing per unit.  We are implementing as each units lease expires.  The tenants were in the building when we bought the building in the spring.

Thanks.
