About Us


Rimfire Energy, is a privately owned electricity business operating in the Northern Territory since 2014.

During that time, we have grown to become the largest non-government retailer operating in the Northern Territory market.

With more than 40 years of relevant electricity industry experience, Rimfire Energy's team is here to provide you with Competitive Energy.

We have customers in all segments of the market, ranging from smaller domestic and SME business customers, through to the larger C&I business customers.

We are currently the only electricity retailer in the Territory offering discounted pricing below the regulated tariff for our domestic and SME business customers.

In addition to our discounted tariffs for the smaller customers, our competitive customised price offerings have saved tens of thousands, and in some cases hundreds of thousands, of dollars on their electricity bills each year for our larger C&I business customers.

We are committed to reducing the cost of electricity for all our customers through lower prices, improved efficiencies and finding better ways to deliver electricity to you and better ways for you to consume that power.

In short, Rimfire Energy is committed to Competitive Energy and that means we are committed to providing you with competitive energy prices and quality customer service.
