 Go to Increasing/Decreasing Supply for all information on how to change your MIC.
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.
You should discuss your electrical needs with an Electrical Contractor, with whose help you 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.
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 and 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
To connect an electric fence with a load less than 2 kVA go to Unmetered Electric Loads (less than 2kVA).
You will need to establish first if the load is 3 kVA or less if so you can download the NC2 Application Form (PDF | 493 KB) or go to Single House to apply online. Please state that the supply is required for farm lighting.

A modification fee is the fee applicable for processing a modification to an existing contracted connection agreement. This fee covers the commercial and technical processing of the modification application by the System Operator(s) (SOs).
