Transmission loads, large distribution loads & large generators
Enquire to discuss connecting a transmission load, a distribution load ≥ 10MVA or any large generator ≥ 1MVA to our network.
The information below applies to the following types of load and generator connections (Please note: certain process activities, costs and timeframes may differ for distribution connection):
- All transmission connected loads and generators
- Large distribution-connected generators (≥1MVA)
- Large distribution-connected loads (≥10MVA)
Connection process overview
To start this stage, you will need to complete and submit an enquiry form to connect to a new location or modify an existing connection point and provide the relevant critical project criteria evidence for us to assess the criticality of your project.
By registering for a My Western Power Account you will be able to submit and check status of your enquiry.
During the enquiry stage, we will identify a suitable network connection option to assist you with evaluating the feasibility of your project and preparing a Connection Application.
Learn more about the Enquiry stage process activities, including approximate costs and timeframes,.
After your initial enquiry, if you want to progress with your project, you will need to complete and submit a Connection Application and provide the relevant critical project criteria evidence for us to assess the criticality of your project.
During this stage we use your completed application and preferred connection option to perform network studies to identify network capacity and any network constraints. Based on this we will confirm the scope of work required to support the connection of your facility to the network.
We allow customers to complete detailed design, procurement and construction for greenfield assets, by engaging agreed vendors directly.
Please refer to Customer Design & Construct (D&C) for more information on the requirements and suitability for your project.

Before we commence Scoping stage activities, you will need to provide the relevant critical project criteria evidence for us to assess the criticality of your project.
During this stage we use the confirmed scope of work to prepare a concept design and Execution stage cost/timeframe estimate for the technical solution required to meet your project requirements.

Before we commence Planning stage activities, you will need to provide the relevant critical project criteria evidence for us to assess the criticality of your project. The Generator Performance Standards (generator connections) and dynamic model (all connections) for your facility will need to be assessed and validated before we make you an offer to connect.
During this stage we prepare the business case and Access Offer contracts for the final technical solution, to enable your connection to the network.

During this stage we will complete the dynamic network studies, detailed design, procurement, construction and commissioning of the required network modifications and your facility (as applicable) under the terms of your Interconnection Works Contract (IWC).
Once constructed and commissioned, the new or modified connection assets can begin operating under the terms of the Electricity Transfer Access Contract (ETAC) and we can formally close out your project.
