Energetics explains different tariffs in the Queensland region.

 

Energex

The key changes to Energex's network tariffs are to the prices of the tariff components. There have been no significant changes to the underlying structure of the tariffs. Sites within Energex's supply area are divided into the four categories below. For those categories for which network prices are published, an indication is given of the likely changes a site will see in its network charges:

  • Standard Asset Customers: Most sites using less than 4GWh per year are likely to be classified as a Standard Asset Customer (SAC). For SACs, network prices have generally increased by between 5 and 10%.
  • Connection Asset Customer: Sites consuming between 4GWh and 40GWh are likely to be classified as a Connection Asset Customer (CAC). For CACs, depending upon the network charge category applicable to the site, the published components of the network prices (ie non-site specific components) have increased or decreased by up to 10%.
  • Embedded Generators: Pricing is similar to that for CACs.
  • Individually Calculated Customer (typically greater than 40GWh): prices are site specific and not published.

Ergon Energy

The network charges that apply to a site are highly dependent upon the physical location of the site within Ergon Energy's supply area. Ergon's network charges are divided into the following two components:

  • A "transmission" component which is determined by the node of the transmission network the site is supplied from.
  • A "distribution component" which is determined by the size of the site, how it is connected to the distribution network, and whether it is located in the "East" or "West" zone of Ergon's supply area. This component is usually greater than 60% of a site's network charges.

Significant changes have occurred to the prices of both components. The price changes for the transmission nodes are typically in the range +10% to -20% however some have increased by up to 80% and others decreased by 30%.

Prices in the distribution component (based on those which are published) have generally increased by anywhere between 0% and 50% depending upon the distribution charge category the site falls into. Sites in Ergon's West zone will see significantly greater increases than those in the East zone, and in some cases prices in the West zone have increased by over 50%.
