NT residential customers are supplied on regulated tariffs with no competing retail offers, so there is no plan to switch to.
How we worked this out
The Northern Territory operates a separate regulated market, with Jacana Energy the main residential supplier and rates set by the Territory Government.
Typical bills use average single-rate residential rates for 2026–27 (effective 1 July 2026), from the AER Default Market Offer and ESC Victorian Default Offer determinations, reviewed 20 July 2026. Cheapest plan figures are indicative, based on the lowest-cost plans on our panel excluding conditional discounts. Your bill depends on your retailer, tariff type, meter and usage pattern. This is a guide, not a quote.
The Northern Territory has a regulated electricity market with very limited competition. Jacana Energy and Rimfire Energy are the main retailers, operating on the Power and Water Corporation network. Prices are regulated by the Utilities Commission of the Northern Territory.
The NT has one of the most unique electricity markets in Australia. Extreme heat drives very high air conditioning usage, particularly in the Top End, where cooling can account for 50% or more of a household's electricity consumption. The NT also has a growing solar industry, with Darwin's high irradiance levels making rooftop solar highly productive.
Our take on electricity in the Northern Territory
The NT market offers limited retailer choice, but tariff optimisation matters. The NT has a unique off-peak period from 9am to 3pm daily, reflecting the surplus of solar generation during those hours. If you can shift your air conditioning pre-cooling and other heavy usage into that midday window, the savings are meaningful.
Solar is extremely effective in the NT, particularly in Darwin and Alice Springs which have some of the highest solar irradiance in Australia. If you do not have solar panels and own your home, the payback period in the NT is short due to the combination of high irradiance and high electricity usage from air conditioning.
For remote communities in the NT, electricity is often supplied by local microgrids or diesel generation. Prices in these areas are regulated to be comparable to urban areas through government subsidies, but the actual cost of supply is much higher.
