Maximum Import Capacity
All half hourly metered customers are allocated a standard Maximum Import Capacity (MIC). Many of these are legacy values from when the site was first connected, and the allocated capacity remains unchanged unless requested to be increased or decreased by the customer.
kVA is a measurement of apparent power, and tells you the total amount of power in use in a system. The MIC value should reflect the maximum amount of power that should be consumed. You may need to upgrade your kVA to accommodate more electrical goods or reduce your kVA if you are not using as much electricity. Did you know that you could be charged up to twice as much if you are using more than your allocated capacity? This will be reflected in the electricity bill you receive from your supplier which outlines how much kVA you are using each month. There will be no charge associated with reducing your MIC, however increasing your MIC could result in the need for reinforcement of the network in order to cope with the additional demand.
