What is smart sub-metering and how does it work?
Smart sub-metering puts residents in multi-unit residential and commercial buildings in control of their own electricity costs by using a dedicated meter to measure the energy used in each individual unit. Smart sub-meters integrate time and use so that they measure not only how much electricity is used but when it is used. Any interval of time can be used however the Ontario Energy Board has set a standard of hourly use for residential consumers.
