Mount Lambie Wind Farm
Mount Lambie Wind Farm
Mount Lambie Wind Farm is a wind and storage renewable energy project proposed near Wallerawang in the Central Ranges of New South Wales.
Consisting of up to 200 megawatts (MW) of wind generation capacity and 100MW battery energy storage (BESS) on-site, the Mount Lambie Wind Farm is anticipated to connect into the existing transmission network, supplying clean energy to the National Electricity Market to contribute to the NSW Government’s target to halve emissions by 2030 and achieve net zero by 2050.
The Mount Lambie Wind Farm would generate enough clean electricity to power about 115,000 Australian homes per year and has been identified for its wind resource and proximity to the major retiring coal fired power station, Mt Piper and the former Wallerawang power station.
The project is being developed by Tetris Energy, an Australian renewable energy company developing a range of wind, solar and storage projects in Australia. With a focus on the long-term viability of regional communities, the development of Mount Lambie Wind Farm will generate significant investment and economic benefits in the broader Lithgow region and will be compatible with existing agricultural and farming activities.
We’ve submitted the Scoping Report to the NSW Department of Planning, Housing and Infrastructure.
Project Benefits
NEAR NEIGHBOUR BENEFITS
Near neighbours to the proposed site will be entitled to share in the financial rewards of the project. These benefits will be available during both the construction phase and the operational life of the wind farm, which we estimate to be up to 40 years. We’ll share more details about our benefits package in Q3 2025.
HOSTING OPPORTUNITIES
All the wind turbines in this project are proposed to be hosted on private land. If you are interested in hosting turbines or other infrastructure on your property, please get in touch with us at info@tetrisenergy.com. We’ll need a map, an address and a couple of reference photos of your location.
DISCOUNTED ENERGY
To recognise community participation in the development of the Mount Lambie Wind Farm to date, we’re working with Alinta Energy to offer a discounted energy offer to residents surrounding the proposed project area. Find out more about the offer soon.
TRANSFERABLE SKILLS
Renewable energy projects – like our wind farms and their infrastructure - require skills in electricity generation and infrastructure. Some of this knowledge already exists in the Lithgow region, which will provide ongoing opportunities in the area. And it will also attract new skills into the Lithgow region to fill any gaps.
MORE COMMUNITY FUNDING
We’ll follow the NSW Department of Planning, Housing and Infrastructure (DPHI) guidelines to fund community-agreed projects like public building upgrades or community sponsorships. Because residents surrounding renewable energy developments should share in their benefits.
INFRASTRUCTURE
UPGRADES
We’ll contribute to local infrastructure as part of the development of this project. Depending on stakeholder preferences, examples could include road upgrades, repurposing wind monitoring infrastructure to improve phone reception, and investing in local firefighting capability such as trucks or monitoring equipment.
EMISSIONS REDUCTIONS
Wind energy helps mitigate the worst impacts of climate change. Recent research by Vestas on the sustainability of its wind turbines found that it takes less than eight months for its turbines to reach energy neutrality – the point where they generate the same amount of energy that was required to produce them. Turbines then produce clean electricity for their remaining 30+ year lifespan.
MORE RELIABLE ENERGY
Having a variety of different energy generation sources – spread across many different locations - helps create a more reliable power network. Especially when renewable power infrastructure is supported by large battery storage systems, like we’re proposing for the Mount Lambie Wind Farm.
CARRYING ON A LEGACY
The Lithgow region is synonymous with power generation. And as more renewable energy projects progress in the region, a new industry in wind turbine component assembly and expert maintenance could grow in region. This could create ongoing jobs in communities like Portland and Wallerawang, building on their storied legacies of industrial employment and contributions to economic development.

Project Overview
-
Tetris Energy is committed to ongoing and genuine engagement with the local community and project stakeholders to build strong relationships and establish a socially sustainable project.
To help promote a high standard of community engagement across the industry, the Clean Energy Council has developed a Best Practice Charter for Renewable Energy Projects with an emphasis on community engagement. Tetris Energy is committed to honouring this charter in our renewable energy projects.
We will continue to engage with neighbours and broaden the consultation effort to include the wider community and stakeholders throughout the planning process as more assessments and investigations are completed and detailed information becomes available.
This consultation will provide valuable local insights into identifying opportunities and constraints for the proposal. Please use the signup form below to register your interest.

Under the EP&A Act, development may be declared State Significant Development (SSD). This declaration may be made by a State Environmental Planning Policy (SEPP) or by the Minister for Planning (the Minister) and is generally based on the scale, nature, location, and strategic importance of the development to the State.
All SSD projects require development consent from either the Independent Planning Commission or the Minister before they may proceed. Prior to determination, they are subject to a comprehensive assessment with extensive community participation. The Department of Planning and Environment co-ordinates this assessment. All SSD projects are determined on their merits, having regard to their economic, environmental, and social impacts and the principles of ecologically sustainable development.
All current State Significant Applications can be found on the Department of Planning and Environment’s Major Projects Portal, which provides a platform to gain an insight into the status of the assessment process, access all relevant assessment materials for the Development Applications, and contact details for the Department’s assessment officer.
Once submitted, the assessment materials for the Mount Lambie Wind Farm, including the Scoping Report and the Project’s Planning Secretary’s Environmental Assessment Requirements, will be accessible on the Major Projects Portal, here. Tetris is currently preparing the Project Scoping Report to inform the SEARs.

Tetris Energy will undertake comprehensive technical, environmental, and social studies which, together with further community consultation, will shape the development of Mount Lambie Wind Farm. This includes continuing our engagement with Lithgow region communities to understand ways that the area can benefit from the project, such a key gap in infrastructure or suggestions for local initiatives, such as development of a benefit sharing program to support the local community and provide a long-lasting legacy in the area.
Investment in Lithgow City Council region will assist:
energy industry transition – from thermal generation to renewable energy.
employment – both direct (technicians, electricians etc) and indirect (concrete, services etc).
energy reliability and security for the region; broader community-led funding initiatives.
provide renewable energy supply for local battery energy storage projects, and
utilise the regions existing transmission assets.

The Mount Lambie Wind Farm will have the potential to supply clean energy to around 115,000 NSW homes and avoid 420,000 tonnes of carbon dioxide emissions each year.
The Australian energy landscape is transitioning to a greater mix of low-emission renewable energy sources, such as wind and solar. Factors driving this transition include:
• Demand for more reliable energy supply.
• Consumer demand for lower energy bills.
• State and federal government commitments to reduce carbon emissions.
• Scheduled closure of fossil-fuel generation sources such as coal.
The Australian Energy Market Operator has identified that storage capacity needs to triple within the National Energy Market to meet electricity demands, while the New South Wales Electricity Roadmap forecasts an additional 2.3 GW of energy storage is needed to maintain system security and reliability.

Once completed, the Mount Lambie Wind Farm is expected to operate for 25-35 years. As a signatory to the Clean Energy Council’s Best Practice Charter, Tetris Energy is committed to working respectfully with wind farm communities, during wind farm development, construction, operation, and end of life decommissioning and takes community concerns regarding decommissioning seriously.
Decommissioning means that the wind turbines, site office and any other ancillary infrastructure is removed from the site, and roads and foundation pads are covered and revegetated, allowing land to be returned to its former use. Typically, landowner contracts and Development Applications contain definite clauses setting out the expectations around rehabilitating the site.

Location
Located ~12km from both Wallerawang and Portland, the site is in the Lithgow City Council with the previously cleared land predominantly used for cattle and sheep grazing. Tetris Energy acknowledges the Traditional Custodians of this land, the Wiradjuri, Gundungurra, and Darug people.
The project is in a major current Energy Generation Zone, located near the former Wallerawang and current Mt Piper Power Stations and the coal mines that supply these. Developing the high-quality wind resource at the site would diversify the local economy and generate significant investment in the broader Lithgow area in a way that is compatible with existing agricultural activities.
Using its renewable energy technical expertise and project development experience, Tetris Energy has identified the Mount Lambie location based on its strong wind resource, access to existing high-voltage transmission lines, and proximity to the major retiring and retired coal-fired power stations, Mt Piper and Wallerawang.
Mount Lambie’s wind generation has what is regarded as an ‘attractive’ daily profile. This is important as the energy generated from the wind farm at either end of the day matches with peak energy demand times across the energy grid.
The Mount Lambie Wind Farm will be complimented by co-located battery storage to maximise the energy generated and captured from the site. A Battery Energy Storage System (BESS) stores excess electricity when the wind is blowing and then dispatches to the electricity grid when demand it at its peak.
An on-site substation will be used to connect the project to the existing electricity transmission network.
