There is no single “Australian solar planning process.” There are eight, roughly, one per state and territory, and within several of them the pathway a project takes depends on its size, location, and land use zoning. Developers who assume their previous project’s approval pathway will apply again on a different site or in a different state are usually wrong, and detailed design documentation has to be scoped around the specific jurisdiction from the outset, not retrofitted once an application stalls.

Why Approval Pathways Vary So Much
Planning and environmental approval for solar and Battery Energy Storage System (BESS) projects in Australia sits primarily with state governments and local councils, and each state has built its own framework, thresholds, and assessment pathway. A project’s size, in megawatts, its location relative to sensitive land uses, and its classification under the relevant state planning scheme all determine which pathway applies and which level of government makes the final decision. This is not a minor procedural difference. It affects what documentation is required, how long assessment takes, and even which minister or authority ultimately signs off. Because this varies so significantly by state and by local government area, the sections below describe general frameworks rather than a single national process, and any project should confirm current requirements with the relevant state planning department and local council directly.
New South Wales: State Significant Development
In New South Wales, utility-scale solar farms above 30 megawatts are generally classified as State Significant Development, assessed by the state’s planning department rather than the local council, with large-scale solar projects assessed against the state’s Large-Scale Solar Energy Guideline. This state-level pathway typically involves a more extensive environmental impact assessment and community consultation process than a standard council development application, reflecting the scale of impact these projects can have. Smaller projects below the State Significant Development threshold are more likely to be assessed at the local council level under the relevant local environmental plan, which is a materially different and often less involved process.
Queensland: State Code 26 and Recent Reforms
Queensland assesses solar farm development applications against State Code 26, a planning guideline specifically covering solar farm development, with development generally requiring impact assessment under the state’s planning framework. Queensland’s planning framework for renewable energy projects has also been subject to reform activity in 2025, including changes affecting how wind and solar farm development applications are prepared and assessed, and the introduction of a community benefit system requiring a social impact assessment report and an executed community benefit agreement to be lodged for an application to be considered properly made. Larger Queensland projects, generally above 50 megawatts, can also be assessed through the state’s Coordinator-General process under different legislation. Given the pace of reform in this space, project teams working in Queensland should confirm the current requirements directly with the Department of State Development, Infrastructure, Local Government and Planning rather than relying on a general summary.
Victoria: Planning Permits and the Development Facilitation Program
Victoria generally requires a planning permit for solar and BESS development, with larger projects assessed under the state’s Environment Effects framework where significant environmental impacts are identified. Victoria has also been actively using a Development Facilitation Program to fast-track ministerial approval for eligible large-scale renewable energy and battery storage projects, an approach the state government has applied to a number of solar and BESS proposals through 2025. This illustrates a broader point relevant across most Australian jurisdictions at present: approval frameworks and fast-track mechanisms for renewable energy are genuinely still evolving, and a pathway or timeframe that applied to a project assessed a year or two ago may not describe the current process.
What Detailed Design Documentation Councils and Authorities Typically Request
Despite the state-by-state variation in process, there is meaningful overlap in the categories of technical documentation that councils and planning authorities typically want to see to assess a solar or BESS development application. This generally includes a site layout plan showing the arrangement of panels, battery enclosures, access roads, and setbacks from property boundaries and sensitive receptors, a civil design package covering drainage strategy, earthworks, and erosion and sediment control, and increasingly for BESS components, documentation addressing fire safety and emergency response planning, given the specific attention battery storage fire risk has received from fire authorities and insurers in recent years. Traffic and access assessments are commonly requested, particularly for construction phase impacts on local roads. Visual and landscape impact assessment is often required where a site is visible from public roads or nearby dwellings, and depending on the site, ecological, heritage, noise, and glint and glare assessments may also be requested. It is worth being clear that these are the general categories of documentation authorities commonly ask for, not an exhaustive checklist, and the specific combination required depends heavily on the site, its zoning, and the specific council or state authority involved.
Additional Considerations for BESS Projects
BESS components of a project frequently attract additional scrutiny beyond what a solar-only development would face, reflecting the relatively recent growth in battery storage deployment and the corresponding evolution in how authorities assess it. Fire safety documentation addressing battery enclosure design, separation distances, and emergency response coordination with local fire services is increasingly a standard request rather than an exception. Some councils and authorities are still developing their internal expertise and processes for assessing BESS-specific risk, which can mean a slower or more iterative assessment process than a comparable solar-only application, and it is worth budgeting time for additional information requests during assessment rather than assuming a BESS component will move through review at the same pace as the solar array.
Sequencing Design Around the Approval Pathway
Because planning assessment typically wants to see a reasonably developed design before it will assess an application, yet final detailed design is often refined after approval conditions are issued, project teams benefit from sequencing their design program deliberately around the approval pathway rather than treating design and planning as entirely separate, sequential workstreams. This generally means developing a design-for-planning package with enough civil, layout, and preliminary technical detail to satisfy the assessing authority’s requirements, while holding certain construction-level details for finalisation once approval conditions, and often DNSP connection terms, are confirmed. Getting this sequencing wrong, either by submitting too little detail and triggering repeated information requests, or by fully finalising construction documentation before approval and then having to rework it against imposed conditions, is one of the more avoidable sources of delay in bringing a project to construction.
What to Do Next
Navigating state-specific planning documentation requirements while keeping a detailed design program on track takes coordination between planning consultants and the engineering team producing the civil, structural, and electrical documentation authorities will assess. AGILE’s solar and BESS system design service produces the technical design documentation that supports planning applications as part of a broader detailed design package, sequenced around your project’s specific approval pathway.
FAQ
Is the planning approval process the same in every Australian state?
No. Each state has its own framework, thresholds, and assessment authority, and even within a state the pathway can differ significantly depending on project size and location, so requirements should always be confirmed with the relevant state and council directly.
What size solar project in NSW requires state-level assessment?
Utility-scale solar farms above 30 megawatts in New South Wales are generally classified as State Significant Development and assessed by the state planning department rather than the local council.
Do BESS components of a project face different approval scrutiny to solar-only projects?
Often yes. BESS components frequently attract additional documentation requirements, particularly around fire safety and emergency response, and some authorities are still developing their assessment processes for battery storage specifically.
What technical documentation do councils typically ask for?
Common categories include site layout plans, civil and drainage design, traffic and access assessments, and depending on the site, visual, ecological, heritage, and fire safety documentation, though the exact combination required varies by site and authority.
Should detailed design be finished before lodging a planning application?
Not entirely. Most projects submit a design-for-planning package with sufficient detail for assessment while finalising certain construction-level details after approval conditions and grid connection terms are confirmed.
Are Australian planning frameworks for solar and BESS still changing?
Yes, several states have introduced or reformed renewable energy planning processes recently, including fast-track mechanisms and new community benefit requirements, so current requirements should always be verified rather than assumed from past projects.
