Distribution Connection and Use of System Agreement

The Distribution Connection and Use of System Agreement (DCUSA) provides a single centralised document which relates to the connection to and use of the electricity distribution networks. It includes the charging methodologies for connection to, and use of, the electricity distribution networks.

All licensed electricity distributors and suppliers are required to become parties to the DCUSA.

If you wish to discuss whether you need to be a party to this code and, if so, how to become one, please contact DCUSA.
