What you need to know about the new Climate Active electricity carbon accounting rules

Are your electricity-based emissions zero because your business is based in the Australian Capital Territory, which buys 100% renewable electricity? Can you deduct the export from your 150 kW system from your electricity emissions? Can you claim the renewable energy proportion of your grid supply? Is the electricity that is being generated from your 99 kW solar system emissions-free, even though you availed yourself of the STC discount? Are your emissions from electricity zero because you just entered into a 100% renewable energy Power Purchase Agreement? Can you deduct GreenPower® purchases from your electricity emissions?

While there are no clear frameworks (other than the GHG Protocol) on how to properly account for electricity-based emissions and their reductions in some countries, we are in a much better position in Australia.

Here, we have the mandatory Renewable Energy Target, which provides the framework for Renewable Energy Certificate creation, and we have a mandatory (NGER) and voluntary (Climate Active) reporting system for emissions.

Climate Active has recently released guidance on how to account for electricity-based emissions and reduction measures, allowing you to get recognition for your renewable energy projects.

The Clean Energy Regulator, which administers the NGER system, is also consulting on the design of a new Corporate Emissions Reduction Transparency report (CERT). If you are a large emitter reporting under NGER, you will be able to show how you are meeting your emissions reduction goals.

Let’s have a look at the new Climate Active rules for accounting for electricity emissions and reduction measures.

New Climate Active rules for carbon accounting for electricity

The Climate Active team recently released a set of rules which are based on best-practice principles in the Greenhouse Gas Protocol Scope 2 Guidance and stakeholder consultation. The new framework applies to annual Climate Active reports from calendar year 2021 and financial year 2020/21 onwards.

One of the most significant changes is that you now need to report both your location and market-based electricity emissions, which is called ‘dual reporting’. If you are reporting under CDP, you will be familiar with this concept.

You must use dual reporting for Climate Active organisation, simple service, building, precinct and event certifications, while you can choose to use a dual reporting method for  product and complex service certifications. You can select either the location- or market-based approach as the primary electricity accounting method, which will determine the number of offsets required to go carbon neutral under Climate Active.

Location- and market-based approach to accounting for electricity emissions

In carbon accounting, one of the most important and largest sources of emissions is the consumption of electricity, which is accounted for under scope 2.

According to the Scope 2 Guidance of the GHG Protocol, there are two distinct methods for scope 2 accounting, which are both useful for different purposes. The methods used to calculate and report scope 2 emissions impact how a company assesses its performance and what mitigation actions are incentivised. When used together, they can provide a fuller documentation and assessment of risks, opportunities and changes to emissions from electricity consumption over time.

The location-based method

This method reflects the average emissions intensity of the grid, based on your company’s location. This method allows you to calculate emissions that you are physically emitting to the atmosphere. So, if your business is located in the ACT, which is 100% renewable, you will still have to apply the NSW grid’s emissions factor, as you are getting your electricity from NSW power plants. The location-based method does not allow for any claims of renewable electricity from grid-imported electricity use.

The only way you can reduce electricity emissions using the location-based method is to site your business in an area where the electricity from the grid has lower emissions (e.g. Tasmania, or New Zealand), to reduce your electricity consumption, or to install behind-the-meter renewable energy systems. Buying renewables will not be recognised under the location-based method.

The market-based method

The market-based method reflects the emissions that you are responsible for from the electricity you purchase, which may be different from the electricity that is generated locally. This method derives emission factors from contractual instruments, such as the purchase of GreenPower®, RECs/LGCs, or bundled renewable energy power purchase agreements. It uses a ‘residual mix factor’ (RMF) to allow for unique claims on the zero-emissions attribute of renewables without double-counting.

Under the market-based approach, you can reduce your electricity-based emissions by being more energy-efficient, by installing onsite renewables and shifting your electricity supply to renewables.

You can choose which method total – market-based, location-based or both—to use for performance tracking and must disclose this in your inventory.

The following sections go through the details of how to treat onsite generation, the export of renewables, the treatment of renewable energy certificates, the purchase of renewables and carbon-neutral electricity.

Treatment of Renewable Energy Certificates

Renewable Energy Certificates consist of Large-scale Generation Certificates (LGCs), from solar PV systems greater than 100 kW, and Small Technology Certificates (STCs), from small-scale solar PV systems of less than 100 kW.

One renewable energy certificate equates 1 MWh of renewable energy generation. You can find more information about these certificates in this blog post.

You can use LGCs to reduce reported electricity emissions under the market-based method, but not STCs.

Market-based method

  • You can use LGCs as a unique claim on the zero-emissions attribute of renewable generation within a Climate Active carbon account (meaning you can deduct retired LGCs from your electricity emissions).
  • You can only use LGCs to account for electricity-based emissions, e.g. direct grid-based electricity (scope 2) or indirect emissions sources (scope 3) consisting entirely of electricity, such as third-party operated data centres, or streetlighting.
  • You must retire LGCs on the Renewable Energy Certificate Registry, with evidence of their retirement, including serial numbers, provided to Climate Active.
  • You should directly retire LGCs in the name of the claimant, for example, ‘Retired on behalf of Company X for 2020 Climate Active carbon-neutral claim’.
  • You may retire LGCs indirectly on behalf of the claimant, for example, by GreenPower®. You should provide serial numbers to Climate Active.
  • In instances where you cannot provide discrete LGC serial numbers, Climate Active may consider accepting other evidence that LGCs have been retired, for example, certificates provided by an electricity generator or electricity bills listing accredited GreenPower® usage.
  • LGCs must have an issuance date of less than 36 months from the end of the reporting year; for example, a calendar year 2020 report (ending 31 December 2020) could use LGCs with an issuance date of no earlier than 1 January 2018.
  • You cannot use STCs to make renewable energy emission reduction claims for grid imported electricity consumption.

Location-based method

  • Neither LGCs nor STCs can be used to make renewable energy emission reduction claims for grid-imported electricity consumption.

Renewable Energy Target

The Renewable Energy Target (RET) is a legislated scheme designed to reduce emissions from the electricity sector and incentivise additional electricity generation from sustainable and renewable sources. The RET consists of two different schemes: the large-scale renewable energy target (LRET) and the small-scale renewable energy scheme (SRES). Your can account for your investments in the LRET under the market-based method.

Market-based method

  • The percentage of electricity consumption attributable to the LRET, as reflected by the Renewable Power Percentage, for a given reporting year, is assigned an emission factor of zero in the carbon account. For example, a business using a total of 1,000 MWh of electricity in 2019, lists 186 MWh as zero emissions (1,000*18.6% (RPP for 2019)).
  • This deduction is not available to you if you are exempt from the LRET (i.e. Emissions Intensive Trade Exposed Industries).

Location-based method

  • There is no separate accounting treatment for the LRET as it is already included in the state emissions factors.

GreenPower®

GreenPower® is an easy way to switch your electricity supply to renewables that are additional to the Renewable Energy Target. If you need more information on how GreenPower® works, please read the GreenPower Guide for Businesses we developed for the GreenPower® program.

You can also obtain accredited GreenPower® under your renewable energy PPA. For more information, please read our GreenPower® PPA blog post.

You can account for your GreenPower® purchases using the market-based method.

Market-based method

  • Accredited GreenPower® usage is assigned an emission factor of zero in your carbon account, regardless of the state in which you are using GreenPower®.
  • GreenPower® use in excess of what is required to account for your direct electricity usage may be used to reduce your other indirect entirely electricity-based emissions (e.g., data centre usage, streetlighting).
  • GreenPower® use in excess to what is required to account for your entire electricity usage cannot be used to offset other non-electricity emission sources in your carbon account (such as, for instance, emissions from your fleet).

Location-based method

  • You cannot use GreenPower® purchases to make zero-emission electricity claims under the location-based method.

Renewable energy Power Purchase Agreements

Renewable energy Power Purchase Agreements (PPAs) are a great way to cost-effectively increase the renewables proportion of your electricity supply. They also allow you to switch your entire electricity to 100% renewables, thus bringing your electricity-based emissions to zero. However, just like with LGCs described above, you need to retire LGCs associated with your PPA to be able to claim the emissions reduction and renewable energy generation.

Market-based method

  • You need to retire LGCs above any mandatory LRET obligations to claim zero emissions for your electricity consumption.
  • Where you cannot be listed on the REC Registry, you need to supply other evidence to the Climate Active team from the retiring body, such as certificates from the electricity provider.
  • You cannot use supplier-specific emissions factors.

Location-based method

  • You cannot use retired LGCs, including under PPAs, to make zero-emissions claims under the location-based method.

Local renewable energy generation

One of the best ways to reduce electricity consumption other than reducing your consumption is to install solar panels or other renewable energy generation systems where your circumstances allow it. If you directly consume electricity from a renewable energy system, it is called a ‘behind the meter’ system.

You can account for behind-the-meter use of renewable generation systems under both the location- and the market-based method. However, you can only account for exported electricity under the market-based method.

Market-based method

  • Behind-the-meter use of electricity from large scale systems may be reported and assigned an emissions factor of zero in your carbon account, only if you retire any LGCs associated with that generation or not create any. An example of when you don’t create any LGCs is when you install a large-scale system, and you choose not to generate any LGCs.
  • If you are creating and selling LGCs, you must treat behind-the-meter usage from large-scale systems the same as electricity consumption from the grid (that is, treated as residual electricity).
  • You may report and assign behind-the-meter use of electricity from small-scale systems an emissions factor of zero in your carbon account, regardless of whether you have created, transferred or sold any STCs associated with this generation.
  • You need to convert exported electricity from renewable systems into an emissions reduction equivalent and net from gross emissions. You can achieve this by multiplying exported electricity by the national scope 2 electricity factor only (to account for transmission losses) for the year of the generation. You must retire any LGCs or not create any. You don’t need to retire any STCs associated with this generation.

Location-based method

  • You may report behind-the-meter use of electricity from large scale systems as zero emissions in your carbon account, provided you retired any LGCs associated with that generation or did not create any.
  • If you create and sell LGCs, you must treat behind-the-meter use from large scale systems the same as electricity consumption from the grid.
  • You may report behind-the-meter use of electricity from small-scale systems as zero emissions in your carbon account, regardless of whether you have created, transferred or sold any STCs associated with this generation.
  • Under the location-based method, you can’t use exported electricity as a reduction in electricity emissions.

Jurisdictional renewable energy targets

Market-based method

  • If you are operating in a jurisdiction where the government retires LGCs (such as, for instance, in the ACT), you can claim the corresponding percentage of emissions impact on your electricity consumption as zero, provided that the LGCs are retired on behalf of the jurisdictions’ citizens and the claim is auditable for the given reporting year.

Location-based method

  • There is no separate accounting treatment, as the emissions benefit is already included in the state factors used to convert electricity consumption into its emissions equivalent.

Climate Active certified carbon-neutral electricity

Market-based method

  • You can convert Climate Active certified carbon neutral electricity into its emissions equivalent and deduct it from the gross carbon account offset liability.
  • You can convert by applying the relevant emission factor for the particular brand of carbon-neutral power.

Location-based method

  • Same rules

Grid-imported (residual) electricity

Market-based method

  • You need to convert electricity usage not matched by zero-emissions electricity attribute claims (residual electricity) into t CO2-e using the RMF according to the below formula: RMF = National EF / (1 – RPP) RMF (residual mix factor), EF (emission factor), RPP (renewable power percentage), e.g. in 2019, the RMF equals: = 0.88 (national scope 2 and 3 EF)/ 0.814 (18.6% RPP) = 1.08 Financial year reports will use the average of the RMF across the relevant calendar years, reflecting the RPP of each 6-month period. While this sounds complicated, Climate Active have electricity calculators that help with calculating the associated emissions.

Location-based method

  • You need to convert electricity use in each state of your operations into t CO2-e using the relevant state NGA factor (either scope 2 and scope 3; or the full fuel cycle factor).
  • The emissions factor used should correspond to the reporting year where possible, i.e. a 2018 reporting year should use the 2018 NGA factors.

What you need to know about accounting for LGCs, STCs, ESCs, VEECs, ACCUs

This blog post has been updated in Dec 19 to reflect the re-branding of NCOS to ‘Climate Active’.

For many sustainability managers, navigating the many acronyms that exist for renewable energy certificates like LGCs and state-based certificate schemes like ESCs for carbon reduction activities can be confusing. Some schemes are federal; others are state-based. Some relate to energy, others to carbon. Some can be used for carbon reduction; others can’t. To make sense of these three and four-letter acronyms, we thought it was time to publish a blog post on this topic.

Renewable Energy Certificates (RECs)

Description

Once electricity from renewable sources enters the grid, it mixes with electrons from multiple sources, like coal-fired power plants, and becomes indistinguishable. To track renewable energy, Renewable Energy Certificates (RECs) are assigned for every megawatt hour created from renewables. Each REC is assigned its own unique number to track the ownership of the environmental (and social) benefits of the renewable energy. They can be traded separately from the underlying electricity.

Renewable Energy Certificates (RECs)
Renewable Energy Certificates (RECs)

Renewable Energy Certificates (RECs) were created to spur the development of renewable energy generation through a market-based mechanism of supply and demand. A REC has a financial value attached to it, which fluctuates depending on prevailing market conditions.

In Australia, RECs are supported by Australia’s Renewable Energy Target, which states that by 2020, 33,000 GWh must be generated from renewable sources (this equates to about 23.5% of the overall total). The scheme ends in 2030.

RECs are divided into Small Scale Technology Certificates (STCs) and Large-Scale Generation Certificates (LGCs).

Treatment

The party that owns the REC owns the claim to that megawatt hour of renewable energy. Renewable energy certificates are used to offset electricity consumption. They cannot be used to offset other emission sources like fuel consumption or Scope 3 emissions like waste or business travel.

Small-scale Technology Certificates (STCs)

Description

STCs are like an upfront subsidy for renewable energy systems that are under 100kW. They are deemed upfront and come with your renewable energy installation.

Treatment

Under previous Australian carbon accounting rules (Climate Active) selling the STCs (i.e., claiming the subsidy) meant that you were not allowed to account for the emission reduction. However, under revised Climate Active’s rules, behind-the-meter energy usage originating from small-scale onsite generation systems can now be treated as zero-emissions energy, regardless of whether any STCs have been created, sold or transferred to any other party. This applies to systems installed in the past as well as future installations.

As such, you can add the self-consumption of electricity from your solar PV systems to your total demand for electricity, and this generation is treated as zero-emissions electricity for your carbon footprint. You can also use the generated renewable electricity against your renewable energy target.

Large-scale Generation Certificates (LGCs) from onsite renewable energy generation

Description

If your renewable energy system is larger than 100kW, you are eligible for one LGC for every megawatt hour your solar PV system generates. As opposed to STCs, the LGCs are not deemed upfront. You need to keep track of your renewable energy generation on an annual basis to be able to create and then sell LGCs. While LGCs currently have a much higher market value than STCs, this can change in line with the supply and demand for certificates by liable entities (like electricity retailers).

Treatment

If you sell the LGCs, you will generate income. However, if you sell your LGCs, the carbon reduction and renewable energy generation associated with the energy generated cannot be claimed.

According to the Climate Active, behind-the-meter energy usage originating from large-scale onsite generation systems that have created LGCs can be treated as zero-emissions energy only if the equivalent amount of LGCs are voluntarily retired. Behind-the-meter energy usage that is not matched by an equivalent amount of voluntarily retired LGCs must be accounted for in the same way as grid-based energy, and offset accordingly if a carbon neutral strategy is pursued.

Large-scale Generation Certificates (LGCs) from offsite renewable energy generation

Description

Rather than having a system onsite, you can purchase LGCs from a renewable energy project that is grid-connected, or offsite. There are principally two options to purchase offsite LGCs – either through a Power Purchase Agreement (PPA) or through a broker.

Treatment

Large-scale Generation Certificates (LGCs) are treated the same as the purchase of GreenPower® provided the certificates are retired. If you have entered into a PPA without obtaining and retiring the LGCs (purchasing the black portion only), then you cannot claim the emissions reduction/renewable energy attributes from the project.

 

A note on surplus electricity

The treatment of surplus electricity from renewable energy and batteries from the perspective of renewable energy and carbon abatement claims is complex. You can read more about this topic in our blog post at  https://100percentrenewables.com.au/how-to-account-for-exported-solar-electricity/.

GreenPower®

Description

The GreenPower® program is an independent government accreditation scheme and is recognised as the most highly regarded standard for offsite renewables in Australia. GreenPower® purchases are additional to Australia’s Renewable Energy Target, and an extensive two-tier auditing process ensures that no double counting can occur. To purchase GreenPower®, you can approach your electricity retailer, buy from an independent provider, decoupled from your electricity agreement or through a GreenPower® PPA.

Treatment

The purchase of GreenPower® is considered to be equivalent to the direct use of renewable energy. This means that you can claim the emissions reduction associated with this action. You can also use purchased GreenPower® towards your renewable energy claims.

Australian Carbon Credit Units (ACCUs)

Description

The Emission Reduction Fund (ERF) is a voluntary scheme that provides incentives for organisations and individuals to adopt new practices and technologies to reduce their emissions. Participants can earn ACCUs for emissions reductions. The ACCUs can be sold to the Commonwealth under a carbon abatement contract with the Clean Energy Regulator, or they can be sold on the voluntary market and are eligible as offset units under the Climate Active.

Treatment

If you generate ACCUs from emissions reduction projects occurring within your boundary, you can claim the reduction as part of your carbon account only if the ACCUs from your projects are voluntarily retired. If the ACCUs are not retired, you are required to account for your emissions without the reductions associated with the projects (i.e. as though the projects had never occurred).

Carbon offsets

Description

One carbon offset represents one tonne of carbon emissions that are not released into the atmosphere, that occur as a result of a discrete project. The emissions reductions from a particular carbon offset project can be sold to enable the purchaser to claim those carbon reductions as their own. Renewable energy is one type of offset activity, but there are many others like energy efficiency or forestry projects.

Treatment

Carbon offsets can be used to offset any emission source, including ones that are not electricity related. You cannot use carbon offset for any renewable energy claims.

State-based white certificate schemes

Description

Several jurisdictions have energy efficiency schemes that require energy retailers to achieve energy efficiency in their customer portfolio. The NSW Energy Savings Scheme and the Victorian Energy Efficiency Target Scheme are the biggest in terms of number of certificates. The ACT and South Australia operate similar, but smaller schemes mainly targeting households and small business.

Energy Savings Certificates (ESCs) – New South Wales only

ESCs created under the Energy Savings Scheme (ESS) reward energy-saving projects through a financial value on every tonne of carbon that is abated by an organisation. The objective of the scheme is to reward companies that undertake projects that either reduce electricity consumption or improve the efficiency of energy use. The ESS began on the 1st July 2009 and is part of the NSW Government’s plan to cut greenhouse gas emissions. The scheme is legislated to run until 2025 or until there is an equivalent national energy efficiency scheme.

Victorian Energy Efficiency Certificates (VEECs) -Victoria only

The VEET scheme was established under the Victorian Energy Efficiency Target Act 2007 and commenced on 1 January 2009. Each VEEC represents one tonne of carbon dioxide equivalent (CO2-e) abated by specified energy saving activities known as prescribed activities. The abatement is calculated by comparing the difference between the energy use after the completion of an upgrade or project and the ‘baseline’ energy use, which refers to the amount of energy that would have been used if the energy efficient installation/project had not taken place. VEECs are bought by large energy retailers with a liability under the scheme.

Treatment of white certificate schemes

You are not required to account for state or territory-based energy efficiency schemes. Emissions reductions resulting from activities supported by these schemes can be counted towards your carbon account regardless of whether any associated certificates have been created, sold or transferred to any other party. So, in short, you can claim the ESCs/VEECs/other white certificates and the carbon reduction.

 

Carbon accounting for all these different federal and state schemes can be confusing, as may be accounting for your Scope 3 emissions. If you need an expert to help you with putting your carbon inventory together, please contact Barbara or Patrick.

Breaking through the 100 kW ceiling

In this article, we are looking at the reasons you should consider installing greater than 100 kW solar PV systems and who is leading in this field.

Australia has the highest number of solar PV systems per-capita in the world, with over 1.7 million systems installed since 2001. The total installed capacity surpassed 5,000 MW in early 2016, and just 20 months later it passed the 6,500 MW level[i].

Solar PV installations have increased in both number and size

Households have driven the total number of installations and have provided most of the installed capacity. However, utility and commercial-scale solar have become more prominent in recent years, and have helped to increase the average size of all installed solar PV systems from 1.77 kW in 2010 to almost 4 kW by the end of 2017.

At the utility level, we have seen projects such as the Nyngan 102 MW, Moree 56 MW and Broken Hill 53 MW systems completed, with many of the projects supported by ARENA’s large-scale solar photovoltaics round to come online soon.

At the commercial scale, the Clean Energy Council reported that the 75-100 kW market is the fastest growing sector in the solar market[ii]. This includes businesses who are keen to invest in solar but wish to avail of the upfront discount from Small-scale Technology Certificates (STCs).

Solar PV systems are now breaking through the 100 kW ceiling

Customer-level implementation of solar PV systems greater than 100 kW is also rapidly growing. Let’s analyse solar installations under 4 MW but greater than 100 kW:

  • In 2016 and 2017, almost the same number of installations (96) were installed as those between 2001 and 2015 (103).
  • In terms of capacity, over 37 MW was added in 2016 and 2017 by systems in the 100-4,000 kW range, compared with 38 MW in the preceding 15 years.

Why is this trend occurring?

This trend is significant as it means that accessing the STC as an upfront discount is becoming less important as a driver of the business case for solar. When talking to our customers, the reasons why they are installing or considering installing larger solar PV systems are numerous.

6 reasons why you should install solar PV systems greater than 100 kW
6 reasons why you should install solar PV systems greater than 100 kW

Here are the six reasons why you should go larger than 100 kW:

  1. Wholesale electricity prices – many businesses have seen their contestable electricity costs increase steeply in recent months, in some cases by as much as 250%. In response, business is re-taking control where they can. Solar, as well as efficiency initiatives such as LED lighting, are tangible measures that offer certainty of savings and a long-term hedge against some of the volatility in the market.
  2. Declining costs of solar means it is becoming cost effective without subsidies – Solar Choice’s November 2017 index of solar PV prices[iii] reports that 100 kW systems now have a median price of just $1.12/Watt inclusive of STCs, which equates to around $1.80/watt total cost. This median price continues a downward trend in commercial-scale solar PV prices of close to 20% over the past four years.
  3. Others are doing it – increasingly businesses see competitors and peers in their region and sector installing solar PV systems and reap rewards through recognition and better reputation. More and more businesses are responding by acting themselves to ensure they remain competitive.
  4. Meeting corporate goals/targets – many businesses, particularly large corporates, have sustainability targets which often include ambitious goals for renewable energy and/or carbon emissions, and many businesses also face supply-chain pressure to improve their sustainability performance. Maximising behind-the-meter solar PV on their facilities is a prominent way to achieve sustainability goals, save costs, improve reputation, motivate staff and demonstrate to customers and supply-chain partners how they are ‘walking the talk’.
  5. Large-scale Generation Certificates – while renewable energy incentives are not as ‘critical’ to the business case as they were a few years ago, the availability of LGCs at today’s spot prices, even for a few years, remains an important financial incentive. Conversely for some businesses, retiring their LGCs is a tangible step they take to validate the carbon abatement they achieve from their solar investment.
  6. Battery storage – it’s not front-of-mind, but most businesses are aware of it and know that in a few years’ time storage will be much cheaper and will offer them the ability to derive greater value from their solar investments, through higher self-consumption, load shifting, reduced peak demand and potentially network support. In the meantime, improved feed-in rates for exported electricity helps the business case.

Who is implementing solar PV systems over 100 kW?

Just 18 solar PV systems greater than 100 kW were built before 2012. The Singleton PV power station led the way, originally built for the Sydney Olympic Games in 2000. This system then led the way again in 2015, showing how a generator could contract directly with an end user (University of Technology Sydney) to supply power.

Some of the other ‘early adopters’ of greater than 100 kW systems were local councils such as Coffs Harbour City Council’s Rigby House (136.5 kW) and airports in both Adelaide and Alice Springs. The Northern Territory was the most active region, implementing nearly half of the systems completed by 2011.

Since 2011 the range of sectors and the locations of solar PV systems greater than 100 kW has increased significantly. Most prominent among adopters of these systems are aged care providers, retail properties, wineries, education facilities and mining & manufacturing firms. These tend to be facilities with large roof or land space and large continuous daytime load that can be part-met by on-site solar power.

In terms of scale, many of the largest systems are being installed by the retail property sector and by Universities. CSU’s Wagga Wagga campus 1,769 kW system and Stockland Shellharbour’s 1,218 kW system are prominent examples.

What are our clients planning?

Many of our clients are planning solar PV projects that will well and truly exceed 100 kW.

  • More and more aged care providers are looking at solar PV and embedded network strategies, extending beyond their main buildings to include residential care homes that will enable them to provide lower cost sustainable energy to their residents.
  • We are seeing many local councils and water authorities recognise the potential for solar on water and wastewater treatment facilities, including land, buildings, reservoirs, ponds and dams. Lismore City Council’s 100 kW floating solar plant will undoubtedly see others replicate this approach, benefit from Lismore’s lead and scale up to larger systems.
  • Several Universities are planning systems that will follow UQ’s and CSU’s leadership, and we expect more mining and manufacturing facilities to do likewise.

Your next steps

The business case for maximising your solar PV potential based on your load and available space has become very attractive in the last two years.

As Patrick, technical director at 100% Renewables puts it, ‘We know that energy prices are going up. We know that costs for solar panels are going down. Staff and customers want you to power your organisation with renewable energy. The business case is clear, and organisations with the capacity to install solar can ‘walk the talk’, take back control of their energy costs and improve their triple bottom line.
