If you live in an apartment building, a mobile home, an RV park, or any other multi-family dwelling, your electric bill is probably set up on your landlord's “master meter/sub-meter” billing plan.

What Is a Master Meter?
In a multi-family dwelling like an apartment building or a mobile home park, the landlord will receive a “master meter” electric bill. The landlord uses this master bill to charge tenants for each unit’s electricity use. Rates billed to tenants by the landlord must be the same as the rates billed to the landlord. These rates must be posted in a place where tenants can read them.

What Is a Sub-Meter?
A “sub-meter” measures the electricity use of a single unit in a multi-family dwelling. These meter readings are added together to make one main “master meter” reading. Your landlord can use the sub-meter readings to bill you for your unit’s electricity use, but must use the rates you would receive if you were billed separately.
