Lismore BESS will involve the development of a utility-scale battery energy storage system near Lismore in northern New South Wales; the Lismore BESS will have a capacity of 100MW which will connect into the Lismore 330kV transmission substation. The project will be completed in one stage.

The Lismore BESS would provide the following benefits, specific to Australia’s commitments

Reduction in greenhouse gas emissions required to meet our clean energy transition

Additionally, the proposal would allow for the:

  • Provision of embedded electricity generation, to supply into the Australian grid closer to the main consumption centres
  • Provision of social and economic benefits, through the provision of direct and indirect employment opportunities during construction and operation of the project

The Lismore BESS site is located in the suburb of McKee’s Hill, around 12 km south-west of the Lismore town centre and around 13 km east of Casino, within the Lismore City Council Local Government Area (LGA). The site is located bordering the Lismore 330kV transmission substation to the south.


The Lismore BESS site consists of approx 1.8ha leased land on which approximately 1.5 hectares of land will be used to develop the project. On this website you will see 3D artist impressions of the proposed project that are based on the preliminary layout.

This preliminary layout provides for a 100MW/200MWh BESS; the capacity of the project is based on the available capacity at the Lismore 330kV transmission substation that the project will connect to. The project is a standalone BESS which will charge and discharge from the National Electricity Market and will NOT have a generation component like a solar or wind farm.


Given the project’s capital cost, its development application will be assessed by the NSW Department of Planning, Industry & Environment (DPIE).

In this context, a Scoping Report for the Lismore BESS has been lodged with DPIE in September 2021.

The Scoping Report has been assessed, and DPIE have no issued the SEARs which will outline the requirements for an Environmental Impact Assessment. Studies prescribed include:

  • Studies undertaken will include
  • Heritage (including Aboriginal heritage);
  • Visual amenity;
  • Noise assessment;
  • Hazard assessment;
  • Soils and water;
  • Traffic assessment;

Lithium Iron Phosphate (LFP), LiFePO4, technology has been chosen as it provides proven benefits over other technologies. LFP is a phosphorous-olivine technology rather than a metal oxide layered technology which means it delivers a safer solution to temperature fluctuation resilience and potential thermal runaway risk.

The battery technology is not a liquid acid battery you may typically find in traditional car batteries. Therefore, the batteries don’t have a risk of acid spilling since the technology is constructed using phosphorous-olivine technology, which has a layered lithium-ion structure encased in a gel-type viscosity electrolyte.

The battery cells are housed in individual impact-resistant, leak-resistant aluminium casings. The cell housing is compliant with UN38.3, UL1973, UL9540 and IEC 62619.

The example below illustrates the assembly of a battery pack and the numerous layers that would need to be breached before any external environmental exposure.

In addition, numerous protection elements monitor the cell continually, which will electrically disconnect the battery rack from the system and raise an immediate alarm to the operators.

The Battery Energy Storage System facility has minimal parts that require maintenance. The facility consists of standard equipment you would find in most solar farms, such as switchboards, transformers, protection and metering cabinets and inverters.

We now use battery enclosures connected to inverters. Therefore, the maintenance required on site is very low, requiring general tasks such as cleaning the site area from debris, grass and weeds, vermin control management, and inverter operation checks. The frequency of inspections, depending on the task, may vary. For instance, site cleaning and weed control every three months and inverter checks six-monthly or yearly.

The advancement of battery technology means that batteries require less maintenance and can last longer. The design life expectancy of these batteries is up to 20 years.

Decommissioned batteries are broken down into their base materials, including metals and plastics, to be re-used back into new batteries. All the raw materials containing the cells (lithium, nickel, copper, zinc, lead, magnesium etc), the modules housing the battery cells can also be recycled since they are metal with plastic parts. The battery racks are metal, similar to IT server racks that can also be broken down and re-used. These raw materials can be converted back into functionally operating batteries or other useful equipment.

The advantage of battery technology is that through greater recycling initiatives in Australia, a greater burden on global supply chains from mining raw material and offshore logistics can help with long-term ethical sustainability of battery technology and reduce the impact on the environment.

Battery recycling is gaining momentum in Australia which is mostly driven by the Electric Vehicle (EV) market. The Australian Battery Recycling Initiative (ABRI) is creating opportunities to promote responsible recycling management. More information can be found here:







Contained within the battery enclosures includes fire detection sensors and a condensed aerosol extinguisher. Suppose in the very unlikely event a fire was to occur. In that case, the aerosol will extinguish the fire by inhibiting the chemical reaction present in the fire on a molecular level by removing the flame-free radicals without depleting the surrounding oxygen. The agent itself is environmentally friendly and typically remains suspended in the battery container to help prevent reignition. The materials are non-corrosive, non-conductive and non-toxic and have zero ozone depletion and zero global warming potential. I have attached the brochures of 2 vendors considered for this product.

The battery enclosures, bi-direction inverters, transformers and switchgear equipment will be mounted on concrete hardstands and raised 300mm above the mapped 1 in 100-year flood event. Equipment that contains hazardous chemicals, such as the medium voltage transformers, will be contained within a bund.

Containment bunds will ensure if, in the unlikely event transformer oil is spilt, either when undergoing maintenance or operation, oil will not contaminate the environment. In addition, since the transformer oil bunds are open to rain water, they will have hydrocarbon-absorbent filters for rainwater collected containment bunds. There are many products in the market and is standard practice in the industry for managing MV transformer hardstands as they provide reliable means of preventing hydrocarbons from getting into the surface or groundwater.

Through the planning and environmental application process, a project is held to a high standard regarding the potential effects on the environment and any land or neighbouring property. This assesses what the change in condition to the land will do to affect stormwater runoff changes and proposes mitigation measures to ensure the change of surface conditions does not impact the surrounding land, watercourses, and environment. Aside from just the flow and management of rainfall, we consider contamination of surface water due to accidental spillage of materials such as fuel, lubricants, herbicides and other chemicals used during operational maintenance activities.

During the detail design phase, hydrology engineers will provide detail mitigation and management plans of water run off. The engineers consider operational maintenance scenarios, existing terrain and services, bunding of hazardous areas and filtration of open bund areas.

The detail design is also reviewed and approved by the Environmental Protection Agency (EPA) and Department Planning, Industry and Environment (DPIE). There are a suite of assessments through to the construction stage that ensures run off is managed, mitigated and complied with throughout the process, including:

  • Storm Water Assessment
  • Hydrological modelling
  • Engineering detailed design
  • Erosion and Sediment Control Plan
  • Construction Environmental Management Plan
  • Stormwater and Run Off Management Plan
  • Hazardous material storage plan and emergency plan
  • Australian Standards of equipment, infrastructure and construction
  • Other Fire/ Emergency Plans mentioned above
  • Full suite of further biodiversity and other environmental assessment/ environmental management plans

All of these plans will consider the potential for water run off in development, construction, operation, decommissioning and emergencies, and consider whether these risk of pollution through run off exists, to the level of assessment of Australian Standards, Environmental Planning and Assessment Act, and multiple EPA Acts and sub acts, including:

  • Contaminated Land Management Act 1997
  • Environmentally Hazardous Chemicals Act 1985
  • National Environment Protection Council Act 1995
  • Dangerous Goods Act 2008

A Preliminary Hazard Assessment will be undertaken as part of the initial Development Application. It is quite technical, but does give reassurance in the level of assessment we undertake. This is the first of many assessments that are required through the planning process to ensure a proposed project meets all safety and environment compliances. The BESS project will also complete further assessments before even getting to construction, including:

  • Emergency Response Management Plan. To the satisfaction of State Government, Fire and Rescue, Council and other bodies
  • Fire Management Plan. To the satisfaction of State Government, Fire and Rescue, Council and other bodies
  • Fire Safety Study. Specific analysis and assessment of the BESS infrastructure to prove adherence to Australian standards and to the satisfaction of State Government
  • Numerous other safety and environmental plans, covering off on safety to the community and environment

In Maoneng’s soon to be constructed project in Mornington, Victoria, we have short-listed Contemporary Amperex Technology Ltd. (CATL) as our preferred supplier. CATL is the preferred supplier due to their ability to compliance with international and Australian standards. These include safe transport logistic regulations UN38.3, assembly and operation standard UL9540 and UL9540A, ISO9001, IEC62619-1, IEC 61000-6-2.
