Understanding Connection Capacity

What Connection Capacity should you apply for?

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.

The ultimate electrical load being connected should be carefully considered and we advise that you consult with your Electrical Contractor to obtain the information we require to complete your New Connection Application form.  You can print out the information you will need here and add it to your application when you are ready.
