Customer considerations

Customers are responsible for completing all activities related to securing land for the Western Power owned customer connection assets and shared network assets required for connection to the network (e.g., line route and/or terminal yard), including:

Community engagement and land access negotiations
Environmental spring surveys
Easements and line route corridors
Clearing, working near other asset approvals
3rd party permits, approvals and land acquisitions

Generator connections will proceed under constrained access via AEMO’s Security Constrained Economic Dispatch (SCED) engine and your facility would be subject to SCED control. You are encouraged to consult AEMO’s constraint equations and perform Market modelling to understand the commercial impact SCED may have on the proposed facility, before proceeding with your Connection Application.

It’s suggested that customers consider the following items before commencing the connection process:

Familiarisation with the relevant government policies and Western Power’s guidelines and contract templates
Key project driver:
- Time i.e., progressing faster with less scope/cost/time certainty vs more certainty i.e., prioritising increased scope/cost/time certainty over progressing faster
Appetite for performing self-serve options:
- Steady State Studies
- Load Model Assessment
Engaging an appropriate consultant(s) to support your project with the following if/when required:
- Understanding the energy market, future tariffs and project staging requirements
- Western Power’s connection application process
- Performing network studies and other constraint analysis
- Equipment compliance to WEM/Technical Rules and Generator Performance Standards (GPS) 
- Identifying potential line route(s) for connection assets
- Conducting environmental, planning and heritage assessments and surveys (if/when required)
- Community Engagement consultation with affected landowners, residents, and businesses
Appetite for early procurement of long lead materials
