Construction contestability

SA Power Networks will inform connection applicants where the design and construction of their connection contains a contestable component.

An extension to the existing electrical distribution network may be defined as contestable where:

• the assets can be constructed in isolation from the existing distribution network, and this construction does not adversely impact the security, safety and reliability of the existing network and customers; and
• the assets will initially be used only to supply the connection applicant(s).

The non-contestable portion of an extension is the works required to connect the contestable works to the existing electrical distribution network. This work may only be undertaken by SA Power Networks.

• Modifications to the existing electrical distribution network are also considered non-contestable, and may only be undertaken by SA Power Networks.

Contestable works must be carried out by contracting companies with appropriate skills, licences, insurances, and qualifications. Contracting companies requirements will include:

• Accredited electrical designer to prepare and submit designs.
• Accredited electrical contractor to construct the new electrical distribution assets, in accordance with SA Power Networks’ standards and specifications.
• Accredited civil contractor to undertake associated civil works, in accordance with SA Power Networks’ standards and specifications.

Connection applicants typically engage a consulting engineer to support them though the contestable works process.

Please refer to our External Contractors Companies - Contact List.

The contestable extension will be vested to SA Power Networks. A two-year maintenance period begins when the asset is vested. The new electrical distribution asset will be owned and maintained by SA Power Networks.

Below are some insights into the contestable process:

• The contestable process involves more stakeholders and process steps, when compared to the option of selecting SA Power Networks to complete all works.
• Additional stakeholders and process steps can mean projects take longer, from application to connection.
• The connection applicant will have responsibility for the design and construction of the contestable component, in accordance with SA Power Networks’ standards and specifications.
• Rebates are paid after contestable works have been constructed, successfully complianced, and all conditions met.
• Bonding will be required for the two year defect liability period (Performance Bond), and for early release of titles in a multi lot land development (Clearance Bond).

If you decide not to proceed with a contestable approach, you may still have the opportunity to take responsibility of civil works. In some situations, the civil works component of the project may be removed from the Connection Offer, with SA Power Networks responsible for the design and electrical components only.

An accredited civil contractor must be engaged by the connection applicant, to undertake civil works in accordance with SA Power Networks’ standards and specifications.
