GreenPower for business can sound deceptively simple. Your organisation pays extra for renewable electricity, so it is reasonable to imagine that the electricity arriving at your premises has come directly from a wind farm, solar farm or another renewable generator.
That is not how Australia's interconnected electricity system works.
Electricity generated from different sources enters the grid and is physically mixed. A retailer cannot generally direct particular renewable electrons through the network to your office, warehouse or factory. Instead, GreenPower uses an accredited renewable electricity and certificate framework to match your purchase with eligible renewable generation.
Therefore, understanding GreenPower means separating two things: the physical electricity powering your operations and the renewable energy attributes that support your environmental claim.
That distinction is particularly important for businesses developing sustainability strategies, reporting Scope 2 emissions or comparing GreenPower with renewable energy Power Purchase Agreements. Energy Action's existing material similarly highlights renewable electricity procurement, LGCs and PPAs as important components of business energy strategies.
This guide explains what your organisation is actually purchasing and what to examine before paying for GreenPower.
GreenPower is Australia's government-managed renewable electricity accreditation program. It allows businesses and households to voluntarily purchase electricity matched with renewable generation that satisfies GreenPower's accreditation requirements.
When your business purchases an accredited GreenPower product through a Provider, that Provider obtains eligible LGCs from GreenPower-accredited generators and ultimately retires the certificates required to match audited GreenPower sales. Once retired, those certificates cannot be reused to support another customer's claim.
Consequently, GreenPower is more than a retailer simply describing an electricity plan as green.
GreenPower assesses participating providers, products and generators, while sales are subject to auditing requirements. This provides an external framework for determining whether the renewable electricity represented by a GreenPower product has actually been purchased and accounted for.
This is perhaps the most important concept for businesses to understand.
Suppose your company operates a warehouse in Sydney and purchases 100 per cent GreenPower. The electricity physically reaching that warehouse still comes from the electricity network.
That network contains electricity generated from numerous sources at different times.
Therefore, buying GreenPower does not create a private electrical pathway between your premises and a particular renewable generator. GreenPower itself explains that electricity cannot simply be fed from a nominated renewable generator directly into a customer's workplace through the shared grid.
Instead, renewable electricity is generated and added to the grid, while certificates provide the mechanism for matching the customer's GreenPower purchase with eligible generation.
This distinction does not make the purchase meaningless. Rather, it explains what the product actually does.
Broadly, your organisation is paying for an accredited renewable electricity product under which eligible renewable generation and associated certificates are matched with your purchase.
The basic process looks like this:
| Stage | What happens |
| Electricity generation | An eligible GreenPower-accredited renewable generator produces electricity |
| Certificate creation | Eligible generation can create LGCs |
| Business purchase | Your organisation buys an accredited GreenPower product |
| Matching | Eligible GreenPower LGCs are matched against GreenPower sales |
| Retirement | The relevant LGCs are retired and cannot be used again |
| Verification | GreenPower Providers undergo auditing against program requirements |
The certificate is particularly important because electricity itself becomes physically indistinguishable once supplied through the interconnected network.
An LGC represents one megawatt-hour of eligible renewable electricity generation. GreenPower Providers must use LGCs from generators that meet the program's accreditation requirements for their GreenPower products.
If your organisation buys GreenPower through an accredited Provider, the Provider handles the certificate requirements associated with the product.
For larger organisations, GreenPower Corporate Direct provides another route. Eligible businesses can obtain LGCs from GreenPower-accredited generators and surrender them through the GreenPower framework, subject to its requirements.
Energy Action's previous guidance also identifies LGCs as an important consideration within Australian renewable energy procurement and PPA arrangements.
Certificate retirement is one of the most important parts of GreenPower for business.
Imagine that a renewable generator produces one MWh of eligible electricity and an associated LGC is created. If multiple companies could all use that same certificate to claim the renewable attributes of that MWh, environmental reporting would quickly become unreliable.
Retirement prevents this.
GreenPower states that certificates are retired against GreenPower sales, preventing their reuse for another emissions reduction claim. Providers are also audited annually to verify their GreenPower sales and certificate obligations.
Therefore, when assessing a renewable electricity offer, businesses should not only ask where the electricity supposedly comes from. They should also understand who owns the relevant certificates and what happens to them.
This is another important feature.
Australia already has mandatory renewable electricity requirements. GreenPower deliberately maintains a distinction between those requirements and voluntary GreenPower purchases.
The program states that GreenPower goes beyond the mandatory Renewable Energy Target. Its current rules maintain this distinction because the mandatory component does not provide the same GreenPower assurance around sourcing and independent auditing.
For businesses, this helps explain why GreenPower may carry an additional cost compared with simply purchasing ordinary grid electricity.
You are voluntarily creating demand for an accredited renewable electricity product beyond the mandatory component already embedded within Australia's electricity system.
GreenPower should not automatically be treated as interchangeable with every product carrying a renewable or carbon-related label.
| Option | What the business generally obtains | Key distinction |
| GreenPower | Accredited renewable electricity matched through eligible LGCs | Government-managed accreditation and auditing |
| Standard grid electricity | Electricity supplied through the grid | Renewable content depends on the wider electricity mix and contractual arrangements |
| Renewable PPA | Contractual exposure to electricity and/or certificates from renewable generation | Often longer-term and structurally more complex |
| Carbon offsets | Units representing emissions reductions or removals | Not the same mechanism as purchasing renewable electricity |
| On-site solar | Electricity generated at the business premises | Direct physical generation behind the meter |
A renewable PPA, for example, may provide longer-term pricing arrangements and closer contractual links with a particular renewable project. However, PPAs can introduce more complicated questions around contract duration, pricing, certificate ownership, volume and risk. Energy Action's previous renewable PPA material highlights these considerations.
GreenPower can therefore suit businesses seeking a comparatively straightforward renewable electricity purchasing mechanism without necessarily entering a long-term PPA.
GreenPower does not have to represent all of your organisation's electricity consumption.
Accredited consumption-based products can cover a specified percentage of consumption. Current program information states that the minimum for consumption-based GreenPower products is 30 per cent, while other structures, including block and certificate-only products, are also available.
For example, if a business consumes 2,000 MWh annually, choosing 50 per cent GreenPower would mean purchasing GreenPower corresponding to 1,000 MWh of its consumption.
Moving to 100 per cent would increase that to 2,000 MWh.
However, organisations should determine the appropriate percentage within a broader energy and sustainability strategy rather than automatically assuming the highest percentage provides the best commercial outcome.
Consider your emissions targets, reporting framework, procurement budget, existing solar generation, PPAs and future electricity requirements.
Price is important, but it should not be the only consideration.
First, confirm that the product itself carries GreenPower accreditation rather than relying on words such as green, clean, renewable or carbon neutral. GreenPower advises customers to look for its accreditation mark and check the accredited product.
Next, establish precisely what percentage of your consumption the offer covers. A low percentage GreenPower product obviously produces a different procurement outcome from 100 per cent GreenPower.
Businesses should also investigate:
That final point deserves particular attention. The ACCC says environmental and sustainability claims must be truthful and accurate, and businesses must avoid creating misleading impressions through claims or omitted information.
Accordingly, buying some GreenPower should not become the basis for an exaggerated claim about an organisation's entire environmental performance.
GreenPower works best when businesses view it as one component of energy procurement rather than an isolated sustainability purchase.
For example, a company might combine energy efficiency, on-site solar, competitive electricity procurement and GreenPower. Another large energy user might combine a renewable PPA with GreenPower for electricity consumption not covered by that agreement.
This broader approach matters because electricity cost, consumption and emissions are related but separate issues.
GreenPower can address renewable electricity procurement and associated reporting objectives. However, it does not automatically reduce the amount of electricity your organisation consumes, improve equipment efficiency or guarantee the lowest electricity contract price.
Therefore, businesses should evaluate GreenPower alongside their load profile, retail contract, renewable assets, future demand and sustainability objectives.
GreenPower for business is easier to evaluate once you understand what sits behind the product.
Your business is not purchasing a dedicated stream of renewable electrons delivered directly to its premises. Instead, it purchases accredited renewable electricity supported by eligible renewable generation and LGCs, with certificates retired to prevent reuse of the associated claim. The GreenPower framework also provides accreditation and auditing designed to give businesses confidence in what they have purchased.
However, the appropriate GreenPower percentage and procurement structure will vary between organisations.
Energy Action can help Australian businesses assess GreenPower alongside electricity procurement, renewable PPAs, LGC strategies and broader energy management requirements.

GreenPower for business is a way for Australian organisations to voluntarily purchase government-accredited renewable electricity. Rather than sending electricity from one renewable generator directly to your premises, the system matches GreenPower purchases with eligible renewable generation and corresponding LGCs. Providers are subject to GreenPower's accreditation and auditing requirements, helping businesses substantiate their renewable electricity purchases.
No. Electricity from different generators mixes within the interconnected electricity network, so the physical electricity arriving at your premises cannot generally be separated by generation source. Purchasing 100 per cent GreenPower instead means your electricity consumption is matched with the corresponding amount of accredited renewable electricity through the GreenPower framework.
A Large-scale Generation Certificate represents one MWh of eligible renewable electricity generation. Within GreenPower, LGCs provide an auditable mechanism for linking customer purchases with qualifying renewable generation. Importantly, relevant certificates are retired so the renewable electricity attributes represented by them cannot subsequently support another customer's claim.
No. GreenPower is an accreditation framework for purchasing qualifying renewable electricity, whereas a PPA is a contractual procurement arrangement that can cover electricity, certificates or both. A PPA can offer closer links with particular projects and longer-term commercial structures, while GreenPower may provide a simpler option for organisations that do not want the complexity of negotiating a long-term PPA.
Start by checking that the electricity product is officially GreenPower accredited rather than relying solely on a retailer's environmental marketing language. GreenPower publishes information on accredited Providers and products, and Providers undergo independent auditing to verify compliance and matching of customer purchases. Businesses should also retain procurement and reporting records so their public sustainability statements accurately reflect the percentage and scope of GreenPower they purchase.
