Grid tariff

In practice

In practice, grid tariff calculation is one of the most complex IT tasks in the electricity market. The capacity element requires the MDMMeter Data Management - system for collection, storage, quality assurance and distribution of metering data from the electricity grid. system to identify the three highest hourly averages per month, deduct any solar contributions, and calculate averages per grid level. For grid companies, the KISCustomer Information System - the core system at power suppliers and grid companies for customer management and billing. system must handle different tariffs per grid level (low-voltage residential, low-voltage commercial, high-voltage), seasonal variation, and transitional arrangements. An error in tariff calculation can result in thousands of customers receiving incorrect invoices. For electricity suppliers, the grid tariff is a separate line item on the invoice that is passed through from the grid companyCompany that owns and operates electricity grids and is responsible for power supply to end users. - the supplier requires KIS logic to handle this correctly and separately from the electricity price.

SEFTATvimenning’s VEE engine: validates, estimates and edits metering series with versioned time series and a full audit trail, before data goes to Elhub. delivers the hourly values the tariff calculation rests on. Faulty or missing AMSAdvanced Metering and Control System - the digital electricity meter Norwegian households received from 2019, reporting consumption hourly to Elhub. data feeds straight into the capacity element calculation - SEFTA's job is to make sure that basis is correct before the KIS system calculates the invoice.
