What is the issue?

Polyphase meters are electrical meters used for measuring three phase electricity supply. Polyphase meters are sometimes used in scenarios where each phase is used for a specific purpose e.g. for heating and/or Electric Vehicle charging. Currently smart polyphase meters only provide profile consumption data as a combined value across the three phases. Therefore, the tariffs offered to those consumers who have polyphase metering equipment is applied to the cumulative consumption of all three phases combined, rather than individual phase data. Although, some electricity meters support the measurement of each phase, the Smart Energy Code (SEC) and DCC systems do not currently support functionality that would allow the individual phase data to be retrieved.
