How to change your level of supply

Increasing or Decreasing Electricity Supply

Each connection point on the electricity network has a Maximum Import Capacity (MIC) associated with it. We design our network to provide you with an electricity supply that is in accordance with the specified MIC. If you recently added a large extension to your home or added electrical equipment at your premises that requires extra power, then your current MIC may no longer be sufficient for your needs. An increased MIC may be required in such cases. If you removed some electrical equipment from your business premises, your current MIC level should also be reviewed, as you may need to apply for a MIC reduction. Charges may apply.

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.

How do I change my MIC?

To find out how to increase or decrease your MIC select a option below for domestic or business premises and follow the steps.

Note: If you have not significantly increased the amount of electricity you are using and you are experiencing voltage fluctuations there could be a voltage problem in your premises or on our network. Go to Voltage Issues to find out more.
