Environmental & LGCs

Overview

Environmental obligations are a growing compliance burden for Australian energy market participants. Energy Copilot tracks three primary environmental frameworks: the Renewable Energy Target (LGC/STC markets), the Safeguard Mechanism, and voluntary carbon markets (ACCUs).

Large-scale Generation Certificates (LGCs)

LGCs are created by accredited renewable energy power stations that generate electricity above a baseline. One LGC is issued for each megawatt-hour (MWh) of eligible renewable electricity generated.

LGC Obligations

Registered Electricity Liable Entities (RELEs) must surrender LGCs in proportion to their electricity acquisitions each year:

LGC_obligation = Annual_acquisitions_MWh × LRET_charge_rate_for_year

LRET charge rates are set annually by the CER. The final target under the Renewable Energy Target is 33,000 GWh/year.

LGC Dashboard (/back-office/environmentals/lgcs)

• Registry balance: LGCs held, surrendered, and required for current year
• Spot price tracker: current LGC spot market price ($/LGC)
• Surrender progress: percentage of annual obligation fulfilled
• Acquisition strategy: if holding fewer LGCs than needed, forward price analysis suggests optimal timing to buy
• Registry movements: detailed transaction history from the CER National Registry

Safeguard Mechanism

The Safeguard Mechanism requires large industrial facilities (including some electricity generators and large industrials) to keep net emissions at or below a baseline.

Key Parameters (2024–2030)

Parameter	Value
Facility threshold	>100,000 tCO2-e/year
Baseline decline rate	4.9% per year
Compliance options	Reduce emissions OR surrender ACCUs/SMCs
Penalty	$275/tCO2-e (2025)

Safeguard Dashboard (/back-office/environmentals/safeguard)

• Covered facility list and current baseline
• Estimated actual emissions vs baseline
• Projected shortfall/surplus under different production scenarios
• ACCU spot price and estimated compliance cost
• Baseline determination history

Carbon Emissions Tracking

Energy Copilot calculates scope 2 carbon emissions from electricity consumption using NEM regional emissions factors:

Scope_2_emissions_tCO2e = Electricity_MWh × Emissions_Factor_kgCO2e_MWh / 1000

Regional grid emissions factors are updated annually from the Department of Climate Change, Energy, the Environment and Water (DCCEEW) National Greenhouse Accounts Factors.

Emissions Dashboard (/back-office/environmentals/emissions)

• Portfolio scope 2 emissions: total and by region
• Carbon intensity trends: declining as renewables penetration increases
• Emissions factor comparison: current vs prior year vs 2005 baseline
• Net emissions position: gross emissions minus LGC surrenders

ACCU Market

Australian Carbon Credit Units (ACCUs) are issued by the Clean Energy Regulator for carbon abatement projects. ACCUs can be used to:

• Surrender under the Safeguard Mechanism
• Voluntary offset claims
• Sell into the spot or forward market

The platform tracks:

• ACCU spot prices ($/ACCU)
• Method issuance rates (by project type: avoided deforestation, vegetation, landfill gas)
• Government ACCU purchase price (Australian Carbon Exchange)
