Level 1 ASP

What is an Accredited Service Provider Level 1?

ASP Level 1 contractors are licensed to carry out electrical and civil engineering work for both underground and overhead projects. They have the skills to complete a wide range of electrical services, from minor connections to extensive infrastructure setups.

All companies and their workers and sub-contractors who wish to do design or contestable work on or near the electrical distribution network must be accredited and/or registered with the NSW Department of Planning and Environment, as well as authorised in the appropriate level and class as an Accredited Service Provider (ASP).

According to the accreditation scheme from NSW Trade & Investment which has been recognised by the Minister for Resources and Energy under clause 88 of the Electricity Supply (General) Regulation 2001, Level 1 ASPs undertake work to extend the overhead or underground electricity network or to increase the capacity of the existing network.

The Electricity Supply Act 1995 establishes the framework for competition in the design, construction and installation of electricity works that comprise or are connected to the electricity distribution networks in NSW.
