Metering data

In practice

Metering data is the foundation upon which all settlementTurning metering data into money. Consumption and production per metering point become what each party owes or is owed., billing and balance settlementFinancial settlement between BRPs and the system operator for energy imbalances in a given period. rests. In practice, data flows as follows: the AMSAdvanced Metering and Control System - the digital electricity meter Norwegian households received from 2019, reporting consumption hourly to Elhub. meter logs hourly consumption → the AMIAdvanced Metering Infrastructure - comprehensive system for two-way communication between smart meters and power suppliers' systems. sends data to the grid companyCompany that owns and operates electricity grids and is responsible for power supply to end users. → the MDMMeter Data Management - system for collection, storage, quality assurance and distribution of metering data from the electricity grid. system runs VEEValidation, Estimation, Editing - systematic process to ensure quality of raw metering data from electricity meters. validationThe first step in VEE - automated checks of metering data against technical and logical limits to detect obviously erroneous values. → approved values are sent to ElhubNational hub for metering data and market processes in the Norwegian electricity market. → the KISCustomer Information System - the core system at power suppliers and grid companies for customer management and billing. retrieves data for billing. A single missing hourly value over one week for one customer triggers estimationThe second step in VEE - calculation of missing or rejected metering values based on historical patterns, neighbouring meters or statistical models. - and the estimated value may deviate from actual consumption, which in turn produces incorrect settlement. For MDM systems, the data completeness rate (the share of metering points with complete time seriesMeasurements of the same quantity repeated over time. The order and the timestamp are part of the data, not decoration.) is the most important quality metric.
