LGC certificates are more than regulatory tools—they're strategic assets for Australian businesses committed to sustainable growth. By integrating LGCs into energy procurement, companies can achieve compliance, support environmental goals, and strengthen stakeholder confidence.

As sustainability becomes a central focus for Australian businesses, understanding the role of LGC certificates is more important than ever. Large-scale Generation Certificates (LGCs) are a critical part of Australia's renewable energy framework. They not only support national emissions reduction goals but also offer businesses a tangible way to demonstrate environmental responsibility.
In this guide, we explore what LGC certificates are, how they work, and why they're a valuable asset for any company looking to meet compliance requirements, improve ESG credentials, and lower energy costs through smarter procurement.
An LGC certificate is issued for every megawatt-hour (MWh) of eligible renewable electricity generated by accredited renewable energy sources, such as solar farms and wind turbines. Under the Renewable Energy (Electricity) Act 2000, these certificates are part of Australia's Renewable Energy Target (RET).
| Feature | Description |
| Certificate Value | 1 LGC = 1 MWh of renewable electricity |
| Eligibility | Only accredited generators can create LGCs |
| Trading | Can be traded or surrendered for compliance or voluntary purposes |
| Market | Prices fluctuate based on supply and demand |
The process begins when an accredited renewable generator produces electricity and creates LGCs through the Clean Energy Regulator (CER). These LGCs can then be:
Businesses classified as liable entities under the RET must surrender a specific number of LGCs each year. Failure to comply results in financial penalties.
For other businesses, particularly large energy users, securing LGCs voluntarily ensures alignment with broader environmental regulations and reduces the risk of future compliance costs.
More companies are committing to net-zero and carbon-neutral targets. Purchasing and surrendering LGCs:
Consumers and investors increasingly support companies that prioritise sustainability. Using LGCs shows a clear, measurable commitment to clean energy, which enhances brand equity and stakeholder trust.
The LGC spot price fluctuates, driven by market supply and demand. Strategic procurement allows businesses to:
Many renewable energy PPAs in Australia include bundled LGCs. This offers dual benefits:
| Benefit | Impact |
| Cost Control | LGCs bundled in PPAs reduce exposure to market price volatility |
| Simplicity | Streamlines procurement and compliance efforts |
| Sustainability | Boosts renewable energy claims in ESG disclosures |
LGC spot prices have shown significant volatility:
| Factor | Influence on Price |
| Renewable Energy Target | Higher targets increase demand and price |
| Corporate Sustainability Demand | Rising demand increases price |
| Renewable Supply | Oversupply pushes prices down |
| Market Speculation | Traders can influence short-term pricing |
| Policy Changes | New incentives or RET updates shift market expectations |
| Instrument | Purpose | Key Difference |
| LGC | Mandated under Australia's RET for large-scale generation | Tied to physical renewable electricity generation |
| STC | Used for small-scale installations (residential/commercial solar) | Capped and generally for systems under 100kW |
| Carbon Offsets | Reduce net emissions, not tied to energy generation | Can be from various project types (e.g., forestry) |
Businesses can acquire LGCs through:

An LGC certificate stands for Large-scale Generation Certificate. It represents one megawatt-hour of renewable electricity generated by accredited facilities and is used to meet obligations under the Renewable Energy Target (RET).
Electricity retailers and other liable entities are legally required to purchase LGCs. However, many businesses voluntarily acquire LGCs to demonstrate sustainability efforts and meet internal or investor-driven emissions reduction goals.
LGC prices are driven by market dynamics, including supply and demand, policy changes, and corporate procurement trends. They are traded in a spot market where prices fluctuate based on availability and compliance deadlines.
LGCs are not traditional carbon offsets but do contribute to reduced Scope 2 emissions. By using LGCs, businesses can demonstrate renewable energy usage and support carbon neutrality within ESG frameworks.
An LGC is linked directly to renewable electricity generation, while a carbon credit offsets emissions from broader sources such as agriculture or forestry. Both are used to support sustainability, but they serve different purposes within carbon accounting systems.
