The LGC price plays a pivotal role in the renewable energy strategies of Australian businesses. From compliance obligations to voluntary carbon offsetting, the cost of these certificates affects both bottom lines and environmental commitments. While the market remains volatile, PPAs, expert consultation, and policy awareness offer effective ways to manage risk and plan for the future.

The LGC price—or the cost of Large-scale Generation Certificates—has become a pivotal benchmark for businesses engaging in Australia's renewable energy market. As organisations strive to meet sustainability goals and reduce carbon footprints, understanding LGC pricing trends is crucial for both cost optimisation and long-term procurement planning.
Fluctuations in LGC prices can significantly impact the bottom line of businesses using these certificates to meet compliance requirements or to support voluntary emissions reductions. This article explores the key drivers behind LGC price changes, historical trends, and how Australian businesses can strategically respond through power purchase agreements (PPAs) and smart procurement.
LGC prices are inherently market-driven and subject to the basic principles of supply and demand. However, several specific factors can cause substantial movement:
| Driver | Effect on LGC Price |
| Supply of Renewable Energy | A surplus of LGCs from large-scale renewable projects leads to lower prices. |
| Corporate Sustainability Demand | High demand from businesses with net-zero targets increases LGC price. |
| RET Policy Settings | The Renewable Energy Target creates a base demand for LGCs, affecting price levels. |
| Market Speculation | Trading behaviours and investment movements can cause short-term price spikes. |
| Electricity Market Conditions | Rising grid electricity prices often push up demand for PPAs and LGCs simultaneously. |
The balance between LGC creation from renewable generators and demand from liable entities and voluntary buyers is at the core of price volatility.
Understanding past price behaviour offers insights into potential future market dynamics:
| Year | Approx. LGC Price (AUD) | Market Context |
| 2017–2018 | $80–$85 | Supply constraints and strong RET targets drove prices to record highs. |
| 2019–2020 | $30–$40 | Increased renewable capacity caused oversupply and price drops. |
| 2021–2022 | $35–$50 | Recovery driven by voluntary corporate demand. |
| 2023–2024 | $40–$50 | Market stabilised with balanced supply and demand. |
The historical volatility underscores why businesses should avoid short-term buying strategies and consider hedging mechanisms like PPAs.
While no forecast is certain, a few trends suggest where LGC prices may head:
| Future Driver | Likely Impact on LGC Price |
| Continued Renewable Build-out | May increase supply, putting downward pressure on prices. |
| Stronger Corporate Net Zero Goals | Likely to increase demand, supporting higher LGC prices. |
| Policy Evolution (e.g. post-RET) | Potential volatility depending on how future policies shape compliance demand. |
| Linkage to International Carbon Markets | Could increase demand and LGC value in global markets. |
Businesses need to factor these variables into long-term procurement strategies. Monitoring policy shifts and international trends will be essential for forecasting LGC cost exposure.
One of the most effective tools to counteract LGC price uncertainty is the Power Purchase Agreement (PPA). PPAs enable businesses to lock in renewable energy supply along with the associated LGCs at a pre-agreed price.
| Feature | PPA | Spot Market Purchase |
| Price Stability | Fixed over 5–15 years | Subject to market volatility |
| Contract Flexibility | Tailored to energy needs | High flexibility, less predictability |
| Risk Exposure | Reduced | High |
| Sustainability Value | Guaranteed access to LGCs | Variable and less reliable |
By using PPAs, companies gain certainty in LGC pricing, support long-term sustainability, and avoid the stress of timing the market.
Government policies, especially around Australia’s Renewable Energy Target (RET), remain a fundamental influence on LGC pricing. Even as the original RET nears sunset, state-based targets and evolving national frameworks continue to drive demand.
Key regulatory drivers include:
Businesses that proactively monitor these developments are better positioned to make informed energy procurement decisions.
If your business is procuring LGCs or considering a sustainability-driven energy strategy, consider the following recommendations:
The LGC price plays a pivotal role in the renewable energy strategies of Australian businesses. From compliance obligations to voluntary carbon offsetting, the cost of these certificates affects both bottom lines and environmental commitments. While the market remains volatile, PPAs, expert consultation, and policy awareness offer effective ways to manage risk and plan for the future.

A Large-scale Generation Certificate (LGC) is a unit that represents one megawatt-hour (MWh) of renewable electricity generated and fed into the grid. Businesses use LGCs to demonstrate compliance with Australia’s Renewable Energy Target or to meet voluntary sustainability commitments. The price of LGCs affects operational costs for businesses that procure renewable energy.
LGC prices fluctuate due to the balance of supply and demand. When more businesses seek LGCs—especially under tightening sustainability mandates—prices tend to rise. Conversely, if many new renewable projects enter the market and generate excess certificates, prices can fall. Government policy changes, trading activity, and market speculation also contribute to volatility.
Businesses can reduce risk by entering into long-term Power Purchase Agreements (PPAs), which bundle renewable electricity with LGCs at a fixed rate. This approach eliminates the need to purchase LGCs on the open market and provides cost certainty over several years.
The future of LGC pricing depends on several factors including continued demand from net-zero-focused businesses, new renewable project commissioning, and policy updates. While a significant price spike is unlikely in a balanced market, any regulatory tightening or surge in corporate offsets demand could cause prices to increase.
The spot price is the current market value of an LGC at the time of trade, often volatile and responsive to immediate market forces. The contract price, often tied to PPAs, is pre-agreed between parties and provides longer-term price stability, helping businesses avoid the uncertainty of market timing.
