C&I Customers


Rimfire Energy is an electricity retailer operating in the Northern Territory. We sell electricity to eligible customers in the grid-connected regions of Darwin, Katherine, Tennant Creek and Alice Springs and we are currently considering applications from eligible C&I business customers in all regions.

Are You a C&I Customer?

We will consider you to be a C&I customer if your premise is used for operating a business and has annual electricity usage of more than 750 MWh p.a..

It is likely that we will consider you to be a C&I customer if you are a business customer and have either of the following arrangements:

  1. A negotiated contract and are currently being charged based on negotiated rates (instead of standard published rates); OR
  2. A standard contract and are currently being charged based on unregulated commercial default tariffs.

Indicatively, this means that if your current bills are more than $18k/month, then you will probably fit into the category of a C&I customer.


In order to be able to choose your electricity retailer and become a Rimfire Energy customer, you must have an eligible "smart meter" installed at the premises, also referred to as a remote-read interval meter.

Product & Pricing

Our C&I customers are all provided with customised pricing specific to their consumption patterns, payment terms and external market prices at the time of contracting. C&I customers are charged on an "un-bundled" pricing structure, meaning that your bill will include:

  1. Separate charges for your peak and off-peak energy charges;
  2. Separate charges for your network energy, demand and access charges; and
  3. Separate charges for your LGCs and STCs environmental charges.
