Increase or Decrease your Business Supply (MIC)
The strength of the electrical connection applied to your business is called the Maximum Import Capacity (MIC).
If you recently added electrical equipment that requires extra power, your current MIC may no longer be sufficient for your needs, and an increase in MIC may be required. Also, if you removed some electrical equipment from your commercial premises, your current MIC level will need to be reviewed. A new MIC may be applied for in such cases.
Note: In all cases please consult with your Electrician/Consultant on your appropriate MIC for your commercial premise as MIC costs may vary. ESB Networks do not provide this service.
A change in MIC may also require a change in DUoS group. Please refer to the Rules for Application of DUoS Tariff group in the link below. This document outlines the rules for applying the correct Distribution Use of System (DUoS) tariff (DUoS Group) to a customer’s premises or connection point.

Note: In all cases please consult with your Electrician/Consultant on your appropriate DUoS Group for your commercial premise as DUoS costs will vary according to the size of your connection. DUoS costs can be found in the ESB Networks Statement of Charges.
