Contracts, costs and timeframes
Contracts, costs and timeframes
The table below summarises the Western Power contract(s) used, indicative cost and timeframe estimates, and the Western Power deliverable customers will receive, for each activity during the various stages of the connection process.
Please note, all Western Power time spent on your project is cost recoverable and will be reconciled based on actuals upon completion of the work. Work will not commence until payment has been received. The estimated costs and timeframes shown above are to be used as a guide and will vary depending on project specifics, such as facility size, connection voltage, complexity and geographic etc. Some of these activities can be conducted concurrently so the information above is not an indication of the total duration of all activities. These timings do not factor in queuing times, waiting for payment and delay to customer deliverables.
In addition to these costs, each relevant contract throughout the process will contain Management Support costs to cover the Western Power project support and management resources required to support the delivery of the customer project processing works, including but not limited to administration of contracts, preparing project documentation and deliverables, meetings and communication with the customer, and ongoing sponsorship of the customer Enquiry/Connection Application within Western Power. These cost estimates will be based on an allowance of up to 8 hours per week over the duration of the contracted timeframe.
Following the cancellation, expiry, termination or variation of any invoice the applicant may be liable to pay an administration fee of $550 (inclusive of GST).
A generic schedule containing all the connection process activities, timeframes and customer deliverables can be found here. This will be tailored to your project once we have received and assessed your Connection Application as being complete.
