New Zealand's time-of-day energy rates can total 144 individual rates across the year. For a landlord on-billing tenants, getting every unit of energy into the right rate is difficult to do manually.

Using the Billing module in Schneider Electric Power Monitoring Expert (PME) and custom Quasar frameworks, we calculate the energy consumed through the day, week and month for each individual rate, then generate monthly reports for on-billing tenants automatically.
