Advanced meters mean you'll be getting a constant stream of interval data. This needs to be bundled up based on the time of year, week, day and even allow for public holidays to establish the correct tariff. There may be both import and export (solar) meter present, and one or more gate meters with common area’s to measure.

You may model and pass through the network tariff from the gate meter. However unless this is unbundled, it's impossible for the customer to tell how much relates to the embedded network, how much to the distribution network, and how much is for the electricity they are using. It is increasingly important for customers to see this so they can make an informed decision when changing retailers.
