Every state and territory in Australia runs its own mix of renewable energy grants, rebates, and financing schemes, and almost none of them line up with each other in eligibility, funding cycle, or technology scope. Mapping the right combination for a specific project is a genuine piece of technical and administrative work, which is exactly what AGILE Consulting Engineers’ government grants service is built to support, from feasibility documentation through to the independent technical assessment that most programs require.
This guide sets out the federal and state-level programs relevant to solar PV and Battery Energy Storage System (BESS) projects as they stand in July 2026. Grant programs open, close, and change eligibility criteria on short notice, so treat the figures below as a starting map rather than a final answer, and confirm current status directly with the administering agency before relying on any of it in a business case.
Federal Programs to Map First
Before looking at any state scheme, it is worth establishing what federal support already applies, since most state programs are designed to sit alongside it rather than replace it.
The Australian Renewable Energy Agency (ARENA) funds projects through targeted rounds rather than a single open grant, with current priority areas including large-scale storage, offshore wind infrastructure, hydrogen, and community-scale solar and storage. ARENA’s Community Batteries for Household Solar program is a useful example of how this works in practice: Round 1 committed $124.7 million to 318 batteries, and Round 2 has a further $46.3 million available, with awards expected from April 2026 (source: ARENA, current as of mid-2026). Historically, ARENA has co-funded more than 600 projects with over $2 billion in commitments, though that figure reflects ARENA’s own reporting as of 2024 and should be checked against current data before being quoted in an application.
The Clean Energy Finance Corporation (CEFC) is not a grant body. It is a government-owned green bank providing debt and equity on commercial terms the private market does not yet offer at scale, useful for subordinated or mezzanine positions, longer loan tenors, or technology categories mainstream lenders are still cautious about. The Australian Government added a further $2 billion capital allocation to the CEFC, and the CEFC’s lifetime commitments to renewable energy reached $16.5 billion as at 31 December 2025 (source: energy.gov.au, dated).
The Capacity Investment Scheme (CIS) underwrites revenue for new dispatchable generation and storage through competitive tender, rather than providing upfront capital. As of mid-2026, the CIS has revenue underwriting agreements with 74 solar, wind, and storage projects totalling close to 25 GW of generation and around 35 GWh of storage capacity. CIS Tender 8 awarded 15 battery storage projects adding 4.2 GW and 16.1 GWh in June 2026, and CIS Tender 9, seeking 5 GW of NEM generation capacity, closed registrations on 6 July 2026 with results expected in November 2026 (source: DCCEEW, correct as of July 2026). Tender 9 excludes New South Wales, where proponents instead participate in the state’s own Electricity Infrastructure Roadmap tenders.
The certificate-based Small-Scale Renewable Energy Scheme (SRES) continues to support smaller solar and battery installations, including the Cheaper Home Batteries Program, which discounts eligible battery systems of 5 to 100 kWh by roughly 30 percent for households, small businesses, and community organisations. A tiered structure took effect from 1 May 2026, and the exact discount per kilowatt-hour varies by state due to differences in certificate zone ratings, so confirm the figure for your specific location before budgeting against it.
New South Wales
NSW runs its renewable support through the Electricity Infrastructure Roadmap, targeting at least 12 GW of new generation and a minimum of 2 GW of long-duration storage by 2030, rising to 28 GWh by 2034. Delivery runs through Long-Term Energy Service Agreements (LTESAs) and Long-Term Storage Service Agreements (LTSSAs), competitive tenders run by ASL (the NSW Consumer Trustee, formerly AEMO Services) and coordinated by EnergyCo. LTESA Round 6, announced 5 February 2026, secured 1,171 MW and 11,980 MWh of long-duration battery storage across six lithium-ion projects. Two further tender rounds in 2026 are targeting an additional 2.5 GW of renewable generation and 12 GWh of long-duration storage (source: EnergyCo and industry reporting, correct as of mid-2026).
These are revenue floor contracts aimed at utility-scale developers rather than small business grants, so relevance depends heavily on project scale.
Victoria
Victoria’s most significant recent move for commercial projects is the expansion of the Victorian Energy Upgrades (VEU) program to cover rooftop solar systems between 30 kW and 200 kW for large commercial and industrial sites, announced 3 October 2025. Discounts of up to $34,300 are available, targeting an estimated 57,000 high-energy-use sites such as factories, warehouses, and food processors. Eligible businesses can also access battery rebates of up to 100 kWh through the federal Cheaper Home Batteries Program alongside the VEU discount (source: Clean Energy Council). Victoria has separately supported renewable projects through the New Energy Jobs Fund and Renewable Energy Zone (REZ) activation programs, though these tend to target larger or more strategically aligned projects rather than open commercial rounds.
Queensland
Queensland’s state-level Battery Booster rebate has closed, and there is currently no equivalent state battery grant for businesses. Support for battery projects at commercial scale now runs primarily through the federal Cheaper Home Batteries Program. On the planning side, Queensland introduced the Planning (Battery Storage Facilities) and Other Legislation Amendment Regulation on 11 December 2025, giving stand-alone battery storage facilities a clearer assessment and approval pathway, which matters for project timing even though it is not a funding mechanism. Queensland’s Energy and Jobs Plan, targeting 70 percent renewable electricity by 2032 and 80 percent by 2035, continues to drive transmission and generation investment through the state’s SuperGrid initiative, with periodic support mechanisms for large-scale storage and remote or regional projects.
Western Australia
Western Australia has two state programs worth tracking for 2026. A $50 million low-interest loan scheme is being made available to manufacturers to invest in renewable energy, energy efficiency, and electrification projects including solar and batteries, with applications opening later in 2026 and full details yet to be published at the time of writing. Separately, $9 million in Clean Energy Innovation Grants is available to support projects accelerating industrial and energy sector decarbonisation. At the federal level, the Capacity Investment Scheme is supporting close to 1.9 GW of new renewable generation and 482 MW of battery storage across ten projects in regional WA, which is relevant context for developers assessing grid capacity and connection queues in the state (source: WA Government and DCCEEW reporting, current as of mid-2026, applications and dates should be confirmed directly given the programs were still being finalised at the time this was written).
South Australia
South Australia’s Powering Business Grant offers between $2,500 and $75,000 for eligible businesses and not-for-profits with grouped payroll under $18 million, with the state matching contributions dollar for dollar. Stream 1 covers solar and battery projects specifically. Separately, the City of Adelaide has run a local battery rebate of 50 percent up to $1,000 for businesses within the council area, which is a local government program rather than a statewide one and should not be assumed to apply outside Adelaide’s council boundaries. As with other states, South Australian businesses can also access the federal Cheaper Home Batteries Program for eligible battery capacity. Confirm current round status and payroll thresholds directly with the SA Government before including these figures in a funding application, as business grant rounds of this kind typically run on limited windows.
Tasmania
Tasmania’s renewable energy grant activity sits with Renewables, Climate and Future Industries Tasmania (ReCFIT). The Business Energy Efficiency Scheme (BEES) helps commercial and industrial businesses with the upfront cost of energy efficiency measures, with funding scheduled to close in 2026 or earlier if the allocation is exhausted. PowerSmart for Small Business offers grants of up to $1,000 toward energy efficiency audits for smaller operators. Beyond direct grants, Tasmania’s strategic position is shaped by larger initiatives including Battery of the Nation and Project Marinus, which are pumped hydro and interconnector projects rather than business grants, but which matter for anyone assessing future grid capacity and storage economics in the state.
Australian Capital Territory
The ACT’s primary vehicle for businesses is the Sustainable Business Program, which has offered rebates of up to $10,000 for energy efficient upgrades including batteries. This figure should be confirmed against the current ACT Government program guidelines, as it was sourced from secondary reporting rather than a primary government page at the time of writing. The residential equivalent, the Sustainable Household Scheme, is an interest-free to low-interest loan of up to $15,000, rising to $20,000 from 1 July 2026 at 3 percent interest, and applies to households rather than businesses, but it is a useful reference point given how the ACT structures its broader energy transition support.
Northern Territory
The NT’s Home and Business Battery Scheme previously offered grants of $400 per kilowatt-hour of usable battery capacity, up to a maximum of $12,000, but the scheme has reached its funding allocation and is closed to new applications at the time of writing. Given the Territory’s standalone grid and the practical realities of remote community power supply, most current NT support sits within the Roadmap to Renewables policy framework, which targets 50 percent renewable energy by 2030 through 11 recommendations and 50 enabling actions, rather than in an open grant round. A feed-in tariff of 18.66 cents per kilowatt-hour for exports between 3pm and 9pm has applied since 1 July 2025, which is relevant to project economics even though it is not a grant. Given AGILE’s own operating base in Darwin, this is a jurisdiction worth checking directly and often, as remote area power system programs tend to open and close with less public notice than programs in the larger states.
Stacking Federal and State Support
Federal and state programs can often be combined on the same project, provided the terms of each allow it, and mapping every applicable program before applying is worth the effort rather than an afterthought. A typical commercial BESS project might reasonably combine a federal mechanism such as the Cheaper Home Batteries Program or CIS underwriting with a state-level grant or rebate, provided the technical documentation supports both applications. Programs with technical review components, such as ARENA funding, generally expect an independent feasibility assessment, energy yield or performance modelling with clearly stated assumptions, and a risk assessment covering technical, delivery, and operational risk. Applications heavy on narrative and light on engineering substance tend to underperform at any program with a genuine technical review panel.
Frequently Asked Questions
Which grant should a small commercial solar or battery project apply for first?
Start with whichever federal mechanism applies to your project size, typically the Cheaper Home Batteries Program for smaller battery systems, then layer in the relevant state program. Larger projects should map ARENA, CEFC, and CIS eligibility before assuming a state grant is the primary pathway.
Can a project access both a state grant and a federal program at the same time?
Often yes, provided the terms of each program allow it. This needs to be checked case by case, since some programs explicitly exclude stacking with other government support and others do not.
Do these programs require independent technical documentation to apply?
Programs with any material technical review, including ARENA funding and most state-level business grants above a few thousand dollars, expect supporting documentation such as feasibility assessments, performance modelling, and risk assessments, ideally reviewed by an independent party rather than self-assessed.
How often do state and territory renewable energy grant programs change?
Frequently. Several of the programs referenced in this guide, including Queensland’s Battery Booster and the NT’s Home and Business Battery Scheme, have already closed to new applicants. Treat any specific dollar figure or eligibility criterion as time-sensitive and confirm it directly with the administering agency before relying on it.
Is there a single register that lists every renewable energy grant in Australia?
Not a single authoritative one. ARENA, the CEFC, and DCCEEW’s grants and funding page cover the federal layer, but each state and territory publishes its own programs separately, which is precisely why a project-specific mapping exercise is usually necessary rather than a single search.
Do Pacific island nations have equivalent grant programs?
Not directly comparable ones. Pacific nations generally rely on development finance institutions such as the Asian Development Bank and the Green Climate Fund rather than domestic grant schemes, and the application requirements differ substantially from the programs covered in this guide.
If you are trying to work out which combination of federal and state programs actually applies to your project, and what technical documentation each one expects, that scoping exercise is usually the highest-value hour you can spend before an application goes in.
