Understanding network tariffs

What is a network tariff?

A network tariff is a classification assigned by your electricity network distributor that determines how your electricity usage is charged. It reflects the type of connection, usage patterns, and metering setup at your premises.

The Network Tariff is represented by a Network Tariff Code. Each tariff code defines:

  • The structure of charges (e.g., flat rate, time-of-use, demand-based)
  • The technical requirements (e.g., smart meter, controlled load)
  • The customer category (e.g., residential, business)

How do network tariff codes relate to retailer energy plans?

Retailers may use your network tariff code to determine which energy plans you’re eligible for. This is because:

  • Retail pricing is built on network charges: Your tariff code affects the underlying cost structure.
  • Plan compatibility: Some plans (e.g., time-of-use or solar feed-in) require specific tariff codes.
  • Metering requirements: Plans may require advanced metering that aligns with your tariff code.

Is it possible to request a new network tariff code?

If your electricity usage has changed or you’ve made upgrades (e.g., installed solar panels or changed business operations), you may be eligible for a different network tariff code.

Steps to request a change:

  1. Contact your electricity retailer (the company that sends your bill).
  2. Provide: Your National Metering Identifier (NMI) or account number A brief explanation of the change (e.g., added solar, wish to access different plans)
  3. The retailer will:
  • Assess your eligibility
  • If you are eligible, submit a request to the network distributor
  • Inform you of any metering upgrades or costs involved
