Each substation and circuit are assigned to one of the following categories:
- Green: All operational factors are within tolerable limits and so opportunities may exist to connect additional Distributed Generation without reinforcing the network (subject to detailed studies).
- Amber: At least one factor is nearing its operational limit and hence, depending on the nature of the application, network reinforcement may be required. However, this can only be confirmed by detailed network analysis.
- Red: At least one factor is close to its operational limit and so installation of most levels of Distributed Generation and a local connection is highly unlikely. It may also require extensive reinforcement works or, given the lack of a local connection, require an extensive amount of sole user assets to facilitate such a connection.
The table gives the following information:
- Generation connected by substation
- Generation contracted by substation
- Capacity per substation
- Maximum load per substation
