The Alternative Technology Association (ATA) has identified a need for all twin element meters to be able to calculate net export and net import both of active power (kW) and active energy (kWh) values.

Of the metering configurations specified in NSMP SMI Functional Specification version 0.21, this capability is required for the following:

- Single Phase / Two Element meters with Controlled Load Contactor (second element measures controlled load); and

- Single Phase / Two Element meters for on-site generation (second element measures on-site energy generation).
