As business pivots towards more sustainable operations, and energy prices soar, solar PVSolar Photovoltaic More has emerged as one of the best capital investments a business can make. In Australia Solar PV systems larger than 100kW generate not only energy for the business but also Large Generation Certificates (LGCs). These are Renewable Energy Certificates (RECRenewable Energy Certificate More) that are verified by the Australian Government Clean Energy RegulatorThe Clean Energy Regulator is the Australia Government body responsible for accelerating carbon abatement for Australia through the administration of the National Greenhouse and Energy Reporting scheme, Renewable Energy Target and the Emissions Reduction Fund. More (CER). Each LGCLarge-scale Generation Certificate under the Australian Renewable Energy Target. represents one megawatt-hour (MWh) of renewable energy generated by the Solar PV system, typically registered quarterly or annually.
LGCs are Environmental Attribute Certificates (EACEnergy attribute certificate - generic term for a certificate issued for 1MWh of renewable electricity generated. Used interchangeably with renewable energy certificate (REC). More). Here are some of the benefits:
- They are a tradable asset that can be sold as an additional revenue stream for the solar system asset owner.
a) LGCs can be bought, sold on the spot, forward and option contracts or warehoused for future use.
- They can be used to boast renewable energy or emission reduction goals.
a) Retiring (surrendering) LGCs registered from a behind-the-meter system show how much renewable energy the business used that year; or
b) LGCs can also be purchased & retired to increase the amount of renewable energy a business is using without additional physical assets (buy & retire).
- LGCs can be “stapled” with energy by an energy retailer to provide Greenpower.
- The primary demand comes from the 33 million LGCs purchased by Energy Retailers to meet their obligations under the Australian Renewable Energy Target each year through to 2030.
Northmore Gordon can provide early registration of a solar system with the CER for LGCs; don’t wait till the system is commissioned, by that stage businesses are missing out on LGCs, so you can’t retrospectively register.
Diversified Revenue: Boosting Cash Flow and Return on Investment
Most commercial solar farms and early adopters of solar PV exploit the financial potential of LGCs to bolster their income. The Renewable Energy Target and associated LGCs (and STCsSmall-scale Technology Certificate under the Australian Renewable Energy Target.) were designed to incentivise and drive investment in renewable energy.
Commercial Solar farms sell both energy and LGCs to double their income stream and hence achieve a higher return on investment with both depreciating assets and income streams from LGCs and energy. Many businesses with Behind-The-Meter (BTM) solar systems benefit from lower-cost energy and sell their LGCs to achieve a faster payback on the investment in the solar system. Given the price volatility of LGC investors make use of derivatives (options and forward contracts) to protect their investment.
It is critical to recognise that the LGC represents the renewable component of the energy generated, and once you sell the LGC you can no longer claim that energy is renewable. This is important for businesses with decarbonisation goals.

Corporate Sustainability Goals: Strengthening Brand Image and Stakeholder Relations
Many businesses have signed up to various targets or programs taking action to address climate change. Such targets include Renewable Energy 100% (RE100RE100 is the global corporate renewable energy initiative bringing together large businesses committed to 100% renewable electricity. The members must be influential based on their either their brand, global presence, significant energy use or other characteristics that bring attention to their commitment. All companies must commit to purchasing 100% of their electricity from renewable sources by 2050 and purchase that power in the same location they are using it. Interim targets are 60% by 2030 and 90% by 2040. The program is led by the Climate Group in partnership with the CDP.), Science Based Targets Initiative (SBTiScience Based Targets initiative More), Climate ActiveClimate Active is an accreditation program for Australian companies to certify their organisations, products, services, events, buildings or precincts as carbon neutral. The program is backed and administered by the Australian government. Companies have to measure their scope 1, 2 and material scope 3 emissions, reduce where possible and offset the remainder by purchasing and retiring offsets. Allowed offsets are LGCs for scope 2 and ACCUs, CERs, RMUs, VCUs or VERs for scope 1 or 3 emissions. Annual reporting is required and published on the Climate Active website. Carbon NeutralThe act of offsetting all scope 1, 2 and 3 emissions associated with a product or service. More, CDPCarbon Disclosure Project (CDP) is a not-for-profit charity that runs the global disclosure system for investors, companies, cities, states and regions to manage their environmental impacts., Greenpower, or simply voluntary targets for renewable energy or emissions reductions.
LGCs are an internationally recognised Renewable Energy Certificate (REC) that can be used by all these programs to prove the use of renewable energy. International businesses are using LGCs in Australia and locally sourced RECs in each country they have businesses to effectively buy renewable energy for all their sites.
Companies with even greater aspirations are buying LGCs and RECs to enable them to state categorically that their products or equipment around the world is being run using only renewable energy.
The rate of voluntary surrender against the programs is growing rapidly; in 2022 almost 8 million LGCs were voluntarily retired.

The Renewable Energy Target works by allowing both large-scale power stations and the owners of small-scale systems to create large-scale generation certificates (LGCs) and small-scale technology certificates (STCs) for every megawatt hour of power they generate. Certificates are then purchased by electricity retailers (who supply electricity to householders and businesses) and submitted to the Clean Energy Regulator to meet the retailers' legal obligations under the Renewable Energy Target. obligation) – Source CER
Maximising Investment Value: Seizing the LGC Opportunity
Northmore Gordon is accredited by the Clean Energy Regulator to register Solar PV or Wind and Hydro systems (power stations) allowing us to create LGCs for both behind-the-meter (BTM) systems for business, and grid-connected solar farms for investors. NG has been trading certificates for more than a decade and can provide contracts to reduce volatility, shore up investment plans, or provide LGCs and other certificates to meet renewable energy targets or emissions reduction goals. Going a step further NG has the know-how to provide businesses with complete Net ZeroNet-zero is a term meaning to get to zero emissions, there is no current standard on what getting to net-zero means. For governments a net-zero target is one that covers all scope 1 emissions in their jurisdiction. For business it usually covers scope 1 and 2 emissions, although some companies also include some scope 3 emissions. The Science Based Targets Initiative is currently working on a standard for companies. More Roadmaps, Carbon Neutral accreditations, and carbon reduction pathways.
Take advantage of the LGC-driven growth potential today and ensure a brighter and more sustainable return on investment.
