Changing your level of Supply

Maximum Import Capacity (MIC) is the maximum electricity demand level that can be catered for by your connection to our network. MIC is stated in kilovolt-amps but this value is, in most cases, similar to the number of kilowatts that may be catered for by the connection.

We offer connections that provide for many different levels of electricity usage. When applying for a new connection, you need to specify the maximum electricity demand level you require. This level is then written into the connection agreement as the MIC. We then design our network to provide a connection method in accordance with the agreed MIC.

You should discuss your electrical needs with an Electrical Contractor. Your contractor or consultant will be able to determine what the correct MIC is for your requirements. From our experience, it is almost always much lower than the sum of the kilowatt ratings of the equipment you plan to install.

• It sets an upper limit on the total electrical load you may use.
• It impacts how much you will be charged for your connection.
• If the MIC is too high, you will be paying for more capacity than you need.
• If the MIC is too low, your equipment may not operate correctly and you may incur an excess capacity charge.
