Do you need to upgrade your supply to accommodate more electrical goods? Or not using your full supply and looking to reduce it? Below you will find answers to the questions we get asked most frequently along with some useful contact information.
All half hourly metered customers’ are allocated a Maximum Import Capacity (MIC), many of these are legacy values from when the site was first connected, and the value remains unchanged unless requested to be increased or decreased by the customer.
We may contact you if you are consistently over or under achieving your assigned Maximum Import Capacity. This is to ensure that your capacity is in line with your demand and that you are charged appropriately.
The full set of charges per connection voltage can be found in our Use of System Charges section.
Your monthly meter readings can be provided by us or your electricity supplier.
The MIC value should reflect the maximum amount of power that will be consumed on site. We recommend your MIC should be set to 10% above the peak achieved in the last 12 months to allow for any seasonal variations or anomalies.
For supplies up to 300kVA you can apply for an additional load online or download a PDF application form here.
There will be no charge associated with reducing your MIC, however increasing your MIC could result in the need for reinforcement of the network in order to cope with the additional demand.
DCP161 is a modification to the Distribution Connection and Use of System Agreement (DCUSA) which has changed the charging structure for excess capacity. As of April 2018, any capacity used in excess of your Maximum Import Capacity will be charged at a higher rate, whereas previously all capacity used was charged at the same rate.
