Alternative Connections

On some of our networks, it is not possible to connect further amounts of generation without making changes to our assets. These changes are due to the network reaching the physical limit of power able to be transferred through it and are usually due to thermal, voltage, protection or fault level issues. Network modifications are designed to be the lowest cost solution, however, areas requiring upstream reinforcement may introduce additional costs or timescales for new connection.

Western Power Distribution is now rolling out alternative connections across its four license areas which enable customers willing to have their capacity temporarily reduced to connect ahead of the required reinforcement.

The level of curtailment experienced by the connection can be fixed or dynamic, depending on the type of alternative connection offered. The conditions which will require curtailment to be applied will be detailed in the connection offer and historic data can be provided in order for the customer to estimate the likely level of curtailment, but the actual curtailment level will depend on load, generation and system availability in that area, and is outside of Western Power Distribution’s control. A tool has been developed to model the curtail-ment levels for proposed connections and this will be rolled out to a greater number of areas.

Customers may choose to accept an alternative connection as either an interim connection, pending completion of works required for a standard unconstrained connection, or as an enduring connection which would not attract the apportioned costs of any reinforcement in that area. In both cases, the additional costs of implementing the alternative connection will be applied.
