In most of Australia, renewable energy funding is framed around reducing grid emissions. In the Northern Territory, a large share of it is framed around something more immediate: cutting how much diesel gets shipped, trucked or flown into a remote community to keep the lights on. That distinction shapes almost every funding program worth knowing about in the Territory, and it explains why NT programs look quite different from the state schemes running in NSW, Victoria or Queensland.

Why the NT’s Grid Context Matters
Much of the Northern Territory sits outside the National Electricity Market entirely. Darwin and Katherine run on an interconnected system, but a large number of remote communities operate on standalone microgrids that have historically relied heavily on diesel generation. That changes the economics of renewable energy projects significantly. A solar or battery installation in a remote NT community is not just displacing grid electricity purchased at a retail tariff, it is directly offsetting the cost and logistics of trucking or flying diesel fuel into locations that can be hundreds of kilometres from the nearest depot. This is why diesel displacement, rather than grid decarbonisation in the abstract, is the framing used across most NT specific renewable funding.
NT SETuP and Diesel Displacement
The Northern Territory Solar Energy Transformation Program, known as NT SETuP, is one of the clearest examples of this framing in practice. Funded by the Northern Territory Government with support from the Australian Renewable Energy Agency, known as ARENA, the program integrated 10MW of solar PV capacity with existing diesel power stations across remote communities. According to ARENA’s own knowledge bank documentation, the majority of the systems installed under the program were designed to achieve around 15 percent diesel fuel displacement at their respective sites.
Some sites went considerably further. A 1MW high penetration solar system installed at Daly River, known locally as Nauiyu, achieved roughly 50 percent diesel fuel displacement, according to ARENA, demonstrating what is technically achievable when a solar and storage system is engineered specifically for high renewable penetration on an isolated microgrid rather than simply added on top of existing diesel generation.
The Borroloola Microgrid and What It Signals
More recent projects show where NT renewable funding is heading. The Borroloola microgrid project, comprising a 2.1MW solar array paired with a 1.8MW, 6.6MWh battery energy storage system, known as a BESS, has been designed to help the township reach up to 80 percent renewable energy penetration. According to reporting current as of April 2026, the project is expected to save the Northern Territory Government around 1.2 million litres of diesel every year once operational, and secured ARENA funding as part of a broader push toward First Nations led solar microgrid projects across the Territory.
Projects like Borroloola illustrate the direction NT renewable funding has taken: fewer standalone rebate style programs, and more targeted co-funding of specific, large scale microgrid projects, often developed in partnership between the NT Government, ARENA and local or First Nations organisations.
The Remote Power System Strategy
Underpinning these individual projects is the Northern Territory’s Remote Power System Strategy, which has set a target of 70 percent renewable electricity generation for Indigenous Essential Services communities by 2030. This target gives a sense of the trajectory NT energy policy is on, and it is a useful reference point for any business or organisation considering a renewable energy proposal connected to a remote community power system, since projects that align with this strategy are more likely to attract government and ARENA interest than standalone commercial proposals disconnected from the broader remote power planning.
Current NT Government Business Grants
Checking the NT Government’s business grants and funding directory directly, as of August 2026, shows a smaller and more targeted set of live programs than in some other states. The Solar for Multi Dwellings Grant Scheme is currently open and provides funding to cover up to 50 percent of the total cost of a shared solar system, solar sharing technology, smart meters and battery storage systems, aimed at multi dwelling arrangements rather than single commercial sites. By contrast, the Home and Business Battery Scheme, which previously supported homeowners and businesses purchasing batteries and inverters, is currently listed as closed.
The NT Government also currently runs an Energy Bill Relief program for small business, jointly funded with the Australian Government, which provides relief on electricity bills rather than capital funding for renewable energy equipment. It is not a renewable energy grant in itself, but it is worth being aware of alongside any capital project, since it affects the baseline electricity cost a renewable investment is being compared against.
Federal Pathways Available to NT Projects
Given the relatively narrow set of NT specific business grants currently open, federal programs carry significant weight for Territory based renewable projects. ARENA’s Advancing Renewables Program funds mid to late stage renewable technology deployment on an open, year round basis, and NT projects, particularly those involving remote microgrids, diesel displacement or First Nations partnership, have historically been well represented in ARENA’s project portfolio given the technical case such sites present. The Clean Energy Finance Corporation, known as the CEFC, also provides concessional finance rather than grants, and can be relevant for larger commercial projects that need debt or equity support rather than a co-funding grant.
What This Means for a Business Case
For a Territory business or community organisation building a case for a solar or battery project, the practical implication is that the strongest applications tend to frame the project around diesel displacement, resilience and alignment with the Remote Power System Strategy, rather than purely around emissions reduction in isolation. Diesel logistics costs in remote NT locations are real, quantifiable, and often substantial, and a well documented diesel offset calculation, backed by genuine site data, tends to carry more weight with funding assessors than generic renewable energy framing that could apply to a project anywhere in the country.
What to Do Next
Funding pathways in the Territory are narrower and more targeted than in the larger states, which makes getting the technical case right at the outset even more important. This is the point where an early feasibility study, quantifying diesel displacement, renewable penetration potential and microgrid stability implications, can materially strengthen a funding application or investment case. We’ve helped project teams work through this kind of assessment before approaching ARENA, the CEFC or the NT Government, and would encourage any organisation considering a remote or regional NT project to start with that groundwork.
FAQ
Does the Northern Territory have a state battery rebate for businesses?
The NT Government’s previous Home and Business Battery Scheme is currently listed as closed on the NT Government’s business grants directory as of August 2026. The Solar for Multi Dwellings Grant Scheme remains open and covers battery storage as part of shared solar arrangements.
What is NT SETuP?
NT SETuP is the Northern Territory Solar Energy Transformation Program, funded by the NT Government with ARENA support, which integrated 10MW of solar PV with diesel power stations in remote communities, with most systems designed for around 15 percent diesel fuel displacement.
Why is diesel displacement such a focus in NT renewable funding?
Many remote NT communities operate on standalone microgrids reliant on diesel generation, so solar and battery projects there directly offset diesel fuel logistics costs, not just grid electricity, making diesel displacement a central metric in project business cases.
What renewable energy target has the NT set for remote communities?
The Remote Power System Strategy sets a target of 70 percent renewable electricity generation for Indigenous Essential Services communities by 2030.
Can NT businesses access federal renewable energy funding?
Yes. ARENA and the CEFC both operate nationally and have a track record of supporting NT projects, particularly remote microgrid and diesel displacement projects, alongside any current NT specific programs.
Is the Energy Bill Relief program a renewable energy grant?
No. It is a jointly funded NT and Australian Government program that provides relief on small business electricity bills rather than capital funding for renewable energy equipment.
