What this class covers
ANZSIC class 2620 categorises businesses primarily engaged in operating Australia's high-voltage electricity transmission infrastructure. These entities manage the critical systems that move bulk electricity from generation sources, such as power stations and large-scale renewable projects, to distribution networks that serve end consumers. The classification encompasses operations maintaining the National Electricity Market's backbone infrastructure, including interconnectors between states and regions.
Typical operations in this class include businesses that own or manage:
- High-voltage transmission line networks (typically 66kV and above)
- Transformer substations that step voltage up or down
- System control centres managing electricity flow
- Inter-regional transmission connectors
- Maintenance and operation of transmission infrastructure assets
In Australia, this classification primarily applies to transmission network service providers (TNSPs) who operate regulated monopoly assets under the National Electricity Rules. These businesses play an essential role in maintaining grid stability and enabling competitive wholesale electricity markets.
Primary activities in plain English
Businesses in this class primarily engage in:
- Operating and maintaining high-voltage electricity transmission lines that carry bulk power across long distances
- Managing transformer substations that adjust voltage levels between transmission and distribution systems
- Controlling and monitoring electricity flow through transmission networks to maintain system stability
- Providing transmission services to electricity generators, distributors, and large industrial users
- Planning and developing transmission infrastructure to meet future electricity needs
Exclusions and nearby codes
This class specifically excludes electricity generation activities (classified under ANZSIC 2610) and electricity distribution to end users (ANZSIC 2630). Businesses that primarily generate electricity, even if they operate some transmission assets, typically fall under generation classifications. Similarly, entities that distribute electricity to residential and commercial customers at lower voltages are classified separately.
Nearby classifications include ANZSIC 2640 (Electricity Asset Management) for businesses that manage electricity infrastructure assets without operating them, and ANZSIC 2659 (Other Electricity Supply) for auxiliary electricity supply services not elsewhere classified.
Practical guidance
Businesses operating in electricity transmission must register with the Australian Energy Regulator (AER) and comply with the National Electricity Rules. Most transmission network service providers in Australia are subject to revenue regulation under the National Electricity Law.
For tax purposes, these businesses typically need to register for GST (required if annual turnover exceeds $75,000) and may be eligible for fuel tax credits for eligible activities. Infrastructure investments may qualify for capital works deductions, but specific advice should be sought regarding depreciation schedules for transmission assets.
Workers' compensation classifications for this industry typically fall under high-risk categories due to the hazardous nature of working with high-voltage equipment. Businesses should ensure appropriate safety certifications and compliance with electrical safety regulations in their state or territory.
When applying for business grants or reporting statistics to the Australian Bureau of Statistics, use ANZSIC code 2620 to accurately identify your industry classification. This ensures correct reporting for energy sector analysis and policy development.
