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.

Customer success stories in 2017

As the year draws to a close, Patrick and I reflected on the many success stories of our clients. There have been so many achievements, and we wanted to take this opportunity to showcase a few of them.

Last week, construction started at the East Lismore Sewerage Treatment Plant for the largest floating solar farm in Australia. We were presenting to Lismore City Council on their progress towards their 2023 100% renewable energy goal when the first photos of the construction came through, to much excitement. Not only is this the largest floating solar farm in Australia, but it is also community funded.

Lismore City Council was a Green Globe winner in 2015 for their Renewable Energy Master Plan and a finalist this year for their floating solar project. A video with drone footage and an interview with Council’s Environmental Strategies Officer and the mayor can be seen here.

In November, Tweed Shire Council adopted their Renewable Energy Action Plan unanimously. The Council has a long-term aspirational goal to be 100% renewable. To make sure that Council can reach this target, the following interim goals were adopted:
* 25% of Council’s electricity self-generated from solar by 2022, compared to 2016/2017 use
* 50% of Council’s electricity self-generated from solar, incorporating storage, by 2025 compared to 2016/2017 use

As part of the Renewable Energy Action Plan, Council will invest over $10 million in solar and energy efficiency projects over two stages to 2025.  Council’s commitment has received widespread local coverage, with the Tweed Climate Action saying the plan was “an investment in the future of our community”.

On the topic of adopted Council targets, we would also like to mention Port Macquarie Hastings Council, who adopted their Long-Term Energy Strategy in October 2017, which includes aiming for 100% renewable energy by 2027. Council resolved to pursue and implement the most cost-effective energy projects first and to aim to implement one or more mid-scale solar projects, in the medium to long-term.

As an immediate first step, we were engaged by Council to evaluate the business case for streetlighting. Based on the analysis, Council has engaged Essential Energy to roll out an LED lamp replacement project for eligible local roads.



Coffs Harbour City Council was already committed to a renewable energy future, having adopted their Renewable Energy and Emissions Reduction Plan (REERP) in April 2016. This includes targets of;
* 50% reduction in carbon dioxide emissions from 2010 levels by 50% by 2025, and
* 100% renewable energy for Council operations by 2030

The first stage of the REERP is well underway and will see Council’s energy consumption reduced through a range of energy efficiency and solar projects. Council’s adopted delivery program for the period 2017 to 2021 sees funding committed to implement and monitor the REERP to ensure its success.

In August this year, the University of the Sunshine Coast (USC) adopted their Carbon Management Plan, which will lead them to net zero emissions by 2025. The Plan, developed with 100% Renewables, will see USC continue its impressive sustainability performance, with widespread implementation of solar PV systems, energy efficiency and other carbon management initiatives.

The picture on the left shows the Marginal Abatement Cost Curve for 2040. The implementation of energy efficiency and solar behind-the-meter opportunities will enable the University to achieve carbon neutrality in a cost-neutral, if not cost-positive way.

An organisation which achieved carbon neutrality this year under the Australian Government’s Carbon Neutral Program is CHOICE. 100% Renewables helped CHOICE achieve NCOS accreditation for the baseline year. We are also currently training CHOICE staff, so they can calculate their inventory and populate the NCOS documentation in-house. The carbon footprint covers emissions from the building where CHOICE conducts its business and also includes emissions from associated activities such as business travel and staff commuting to and from work.

As part of its move towards carbon neutrality, CHOICE has installed many measures over the past few years to reduce its footprint. These include more efficient use of their operational resources, LED lights and replacing air conditioning with more efficient models. Solar panels are currently being installed to further reduce reliance on grid electricity.

And last but not least we would like to congratulate North Sydney Council for their plans to transition their community to renewables. Much work has been done by councils to reduce their own operational carbon footprint. Only a few councils are looking outside their operations to the boundaries of the local community, and at measures to reduce their community carbon footprint.

Currently, the uptake of solar PV across the North Sydney LGA is only 5%, well below the national average but similar to many inner-city areas. Council commissioned 100% Renewables to develop strategies on how the uptake of renewables like solar or heat pumps can be increased. A key part of this work was to recognise the needs of the full range of community stakeholders, such as tenants, owners, strata developments, free-standing homes, residents and businesses, and to identify and develop solutions that can meet individual needs. North Sydney Council placed much emphasis on community consultation, so as part of the work, we ran workshops with councillors, a focus group and a large community group to get valuable feedback on what abatement measures will work and how the community wants to be engaged going forward.


Should Councils upgrade to LED street lighting now?

There are around 2.3 million street lights in Australia, consuming close to 0.5% of all electricity generated. Between electricity and use-of-system (SLUOS)[1] charges local Councils and roads authorities are spending upwards of $400 million per year on street lights. For instance, a small regional council might spend $300,000 per year on street lighting for local roads, whereas a metropolitan council in a capital city might spend $2.5 million or more per year.

In many parts of the world LED technology is now the norm for new street lighting and when upgrades are carried out to existing street lights. In Australia, just 10% of street lights have been converted to LED, so there is an enormous opportunity for local governments to make significant savings that will lower their carbon footprint, reduce costs, and provide better public lighting services to ratepayers.

LED technology has been improving for several years, with current products capable of reducing energy demand by 50-60%. There are now numerous initiatives and examples of LED street lighting across Australia. The total greenhouse gas emissions savings if all street lights were converted to LED today would be more than half a million tonnes of carbon emissions per year.

Working with several councils in 2016 and 2017 we have seen that the payback for local road lighting upgrades is around 4 to 5 years. This is partly driven by recent volatility in electricity markets, which is causing higher electricity prices for the next several years for many councils. The case for investing in LED street lighting is therefore very strong.

For many local councils – the 90% who have yet to upgrade to LED – a missing piece is often understanding the business case and the benefits of switching to LED. We strongly urge all local councils to spend time to do this, so that when the opportunity to switch arises, the case has been made and funds are available to pay for the upgrade.

Evaluating the business case can involve an assessment of a number of factors:

1) Eligibility of lamps

The current street lighting inventory can be compared with LED options so that all eligible replacements can be identified. For example, networks may only have replacement options for non-decorative fittings on local roads, and main road lights may not yet be eligible. Councils can work with their network provider to get clarity on what can be done now, and what the expected timeframe for LED-eligibility of all lighting will be.

2) Energy savings

For eligible lamps, the potential savings will involve calculating the change in energy demand for new LED lights compared with the existing technology. It is best to refer to the Australian Energy Regulator’s lighting load table so that energy demand for each type of light is correct. For example, an 80W mercury vapour lamp actually consumes around 96W of power as it has a ballast that also consumes power. The energy savings can be converted to dollars by applying the energy and network rates for street lighting. Remember that a proportion of street lighting energy is consumed during peak times, and not all during off-peak. In our experience energy savings of between 50% and 60% are typical.

3) SLUOS savings

Every year Street Light Use Of System (SLUOS) prices are released, showing the cost per year for the full range of luminaires and mounting structures within a network area. Similar to calculating energy savings, an analysis needs to be conducted of SLUOS charges for all eligible lighting that can be switched to LED. Councils should regularly receive data from their network provider which will confirm the SLUOS rates. These are then compared with the SLUOS pricing for LED equivalents. Councils should engage with their network provider to confirm the estimated benefits. In our experience to date, we have seen savings in SLUOS charges of around 55%.

4) Available incentives

In some states, there are incentives to help councils switch to LED lighting. For example, the NSW Energy Savings Scheme has a public lighting component, which allows efficiency upgrades to access Energy Saving Certificates (ESCs) and claim several years of savings effectively as an upfront discount to the cost of an LED upgrade. This can reduce the upgrade costs by more than 5%. It is also recommended that any potential grant incentives be identified and applied for where applicable. Energy-specific, climate/carbon or community/regional grants could all apply.

5) Timing for the upgrade

Typically the costs of bulk replacements are borne by the network provider and councils simply see billing for energy and SLUOS. However, an upgrade to LED involves a step change in technology, and whole luminaires and not just lamps are replaced. If possible, it makes sense to time an upgrade to coincide with a regular bulk replacement cycle, with the potential that labour costs for the upgrade can be reduced since this is part of the normal process.

6) Other ways to reduce costs

When undertaking a bulk replacement, it is likely that there is a ‘residual value’ remaining in some street lights – that is, capital costs incurred by the network that have not been fully recouped. This could make up around 10% of the LED upgrade cost, more in some cases. However, in our experience, a lot of this cost may be associated with just a small fraction of the assets. Where this is a significant factor councils should work with the network to see if these upgrades can be deferred to a later upgrade cycle and then weigh up the pros and cons of lost savings compared with the reduction in capital cost.

Armed with this analysis councils will be in a position to fully understand both the costs and savings of an LED upgrade to their street lighting. However, upgrading eligible street lights to LED technology should just be the beginning of a council’s efforts to reduce the carbon footprint of this service. There is more that can be achieved in future.

  • Development processes and controls should be examined and modified to ensure that all new land releases and road developments use LED as standard.
  • Off-grid street lights that are powered by solar technology and batteries can significantly reduce installation costs with no network connection requirement.
  • The Street Lighting And Smart Controls Programme (SLSC) is aiming to achieve more savings in street lighting by driving the integration of smart controls with street lights. While just 0.1% of street lighting in Australia has smart controls enabled (through trials), this will change in future and may see energy savings rise to well over 70%.
  • In addition to distributing light more efficiently than conventional street lighting technologies, LED lighting efficiency will continue to improve in other areas. Whereas some LED technologies produce around 100-120 lumens per watt (lm/W) today, in time this will improve. A 300 lm/W future LED will require far less power to provide the same light as LEDs today.

Saving 50-60% with an LED upgrade today makes a big contribution to reducing local government’s carbon footprint. But future advances in LED, smart controls and renewable energy can drive even greater savings in the long term. Active management of street lighting, engagement with council associations and industry bodies, and periodic re-assessment of opportunities to further reduce energy costs will see these savings realised.

Universities demonstrating sustainable energy leadership



The top 23 Australian universities for climate action commitments in 2021


Previously, we looked at commitments of all levels of Government regarding climate change. In this article, we would like to examine another industry segment that is driving ambitious carbon commitments – universities.

When tasked by a university in Queensland to develop their carbon management plan leading them to net zero, we investigated why universities are at the forefront of sustainable energy leadership and found the following three reasons:

  1. Leading by research in sustainable energy technologies

Across Australia, and globally, universities play a crucial role in researching solutions for mitigating climate change.  Australian universities have long led in renewable energy research, prominent examples including the establishment of the UNSW Solar Photovoltaics Group back in the 1970s. UNSW’s School of Photovoltaic and Renewable Energy Engineering and ANU’s Energy Change Institute continue to develop leading research in renewables and low carbon technologies. Across all Australian states and territories multi-pronged research on sustainable energy technologies is developing the solutions for tomorrow’s energy systems. Just a few examples include:

  • Griffith University’s Centre for Clean Environment and Energy
  • University of Newcastle’s Priority Research Centre for Frontier Energy Technologies and Utilisation
  • University of Technology Sydney Centre for Clean Energy Technology
  • University of Melbourne’s Melbourne Energy Institute
  • University of Tasmania’s Centre for Renewable Energy and Power Systems
  • University of South Australia’s Barbara Hardy Institute, which develops leading research on sustainable energy and low carbon living

These efforts, allied to ever-increasing opportunities for sustainable energy study, from degree to vocational education levels, will develop the skills to underpin Australia’s transition to a clean energy economy.

Universities also collaborate in forums like Climate KIC (Knowledge Innovation Community)[1]. Climate KIC is a national cross-sector innovation partnership, which is focused on climate change mitigation and adaptation. Its purpose is to help bring to market innovative climate change solutions by connecting key players across the whole innovation pathway. Amongst the founding members are Curtin and Griffith Universities, as well as the University of Melbourne.

  1. Leading by fossil fuel divestments

Divesting from companies that extract and burn fossil fuels is seen by many organisations as an ethical imperative to help address the problem of climate change. The movement has grown rapidly over recent years, and Australian universities are joining other organisations like councils and super funds in making divestment commitments. Examples of such commitments can be seen in the list below:

  • La Trobe: divest from the “top 200 publicly traded fossil fuel companies ranked by the carbon content of their fossil fuel reserves within five years
  • Swinburne: “divest from companies that earn significant revenues from fossil fuel extraction or coal power generation
  • Queensland University of Technology (QUT): “no fossil fuel direct investments” and “no fossil fuel investments of material significance
  • Monash University and the Australian National University (ANU) have taken first steps to partially divest by targeting coal


  1. Leading by reducing their own carbon footprint

Universities are large energy users, estimated to consume around 11 PJ of electricity and gas annually, leading to emissions of more than 1 million tonnes of CO2-e. According to research from the Clean Energy Finance Corporation[2], Universities may spend as much as $700m on energy per year.

Universities have tremendous potential to improve their sustainability performance and decrease their spend on energy, especially in light of rising energy prices. Being more sustainable is also seen by students as something universities need to excel in and as something students want to be involved with.

Reducing greenhouse gas emissions is thus an increasing focus of university sustainability strategies. While energy efficiency has long underpinned efforts to reduce cost and emissions, rising energy prices and lower technology costs are seeing many universities opt for large-scale on-site solar PV systems, generating emissions-free energy and visibly demonstrating their commitment to leadership and innovation.

More and more universities are setting ambitious goals for renewable energy and carbon abatement within their operations. A scan of carbon commitments made by universities can be seen in the list below:

  • Charles Sturt University (CSU) was the first University to obtain NCOS[3]-accredited carbon neutral status in 2015[4]
  • University of Southern Queensland (USQ) committed to carbon neutrality by 2020[5]
  • University of the Sunshine Coast (USC) committed to carbon neutrality by 2025
  • Macquarie University has committed to a 50% reduction in carbon emissions over 2012 levels by 2030, whilst growth in their operations is projected to increase by 40%[6]
  • University of Sydney has the vision to achieve a 20% carbon reduction across its investment portfolio by 2018[7], of which it has already achieved 40%
  • Monash University is headed towards zero net emissions with no target date, currently. It is also the first University worldwide to have issued a certified climate bond to finance sustainability and clean energy projects on campus[8].

There are also numerous examples where Universities have implemented large-scale solar on their campuses. The University of Queensland, for instance, has installed nearly 4.5 MW of solar at its campuses, including a 1.22MW system at St Lucia[9] (see picture below), the University of Southern Queensland has installed a 1.09 MW system at its Toowoomba Campus[10], and CSU is installing a 1.77 MW system at its campus in Wagga Wagga[11].

Universities are also looking for renewable energy opportunities off site. University of Technology Sydney (UTS) was the first organisation in Australia to directly purchase the output from a solar PV project and have this credited towards their overall energy demand by their retailer (200 kW Singleton II array, NSW)[12]. In May 2017, Monash University invited Expressions of Interest for the long-term supply of 55 GWh of electricity from an off-site renewable energy source. The power purchase agreement will also include the Large-scale Generation Certificates (LGCs).

100% Renewables recently completed the development of a long-term energy and carbon strategy with a university in Queensland which investigated innovative options for energy efficiency and renewable energy projects. The carbon management plan lays out the most cost effective path to achieve carbon neutrality and contains marginal abatement cost curves at 2030 and 2040. The MAC curves display the merits of energy efficiency and renewable energy projects that will see the University make large savings on energy consumption, which can be used to fund renewable energy and carbon offset purchases in future.

The project also included a comprehensive engagement strategy, with a number of workshops and several presentations to the University’s committees to get valuable input and to make sure that the plan had the buy-in at all levels.

[3] National Carbon Offset Standard










10 ways to ‘green’ your electricity supply

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

If your organisation has already implemented a range of energy efficiency measures like changing your lighting to LED, optimising your air conditioning, and engaging your employees to be more energy efficient you may be interested in further options to reduce your carbon footprint.

A great opportunity is to look at ways of greening your electricity supply.

It seems simple, but once you start investigating you will find that there are many options available, with more emerging all the time. So, how to make sense of the growing list and choose the right one for you?

To help you with the selection, we group ten options for greening your supply into three broad categories:

Buying carbon offsets

Buying carbon offsets ties in nicely with a carbon management strategy. You can purchase carbon offsets from overseas or domestically, or from a mix of the two. If you don’t want to deal with purchasing carbon offsets, you can switch your account to a supplier that offers carbon neutral electricity, which automatically reduces your electricity-related emissions to zero. Make sure that the carbon neutral electricity is accredited to the Climate Active to ensure credibility. Currently, Climate Active-accredited carbon neutral electricity for businesses is available from only one supplier.

Installing renewables

If your roof space allows for it and you are not facing any barriers like overshadowing, you can install solar panels. Solar PV panels are ideally suited to many businesses because there is daytime demand for electricity. If sized correctly, most of the renewable energy generation can be used directly, without exporting anything to the grid.

In Australia, the Clean Energy Regulator distinguishes between small-scale (<100 kW) and large-scale generation (>100 kW).  Solar installations smaller than 100 kW are eligible to receive STCs (Small-scale Technology Certificates). STCs lower the cost of a solar installation and act like an upfront subsidy. Installations larger than 100 kW attract LGCs (Large Scale Generation Certificates). On an annual basis, you will need to keep track of the renewable energy generation to be able to sell your LGCs and get a financial return. Please note that if you sell your LGCs, you will not be able to claim the carbon reduction nor the renewable energy generation.

Buying renewables

The most straightforward way to buy renewables is to purchase GreenPower®. If you are large enough, you can also directly purchase LGCs in the spot market, but the minimum parcel size is 5,000 certificates, which is equivalent to the electricity use by a multi-storey office building. Another option which is gaining in popularity is joining a renewable energy buyer’s group, like WWF’s[1], who aggregate corporate demand to simplify the procurement process and to access cheaper rates for renewable energy.

Corporate Power Purchase Agreements (PPAs) are another alternative that is gaining traction in Australia. This is where organisations directly contract with a renewable energy developer to purchase the renewable energy. The advantages of this approach are that you can point to a particular project and claim that this is your source of renewable energy.

People and organisations also love the concept of community renewables. As an example, an organisation with a suitable roof space hosts a renewable energy project, and the community can participate by financing this project. The host agrees to buy the power at an agreed price that is lower than grid electricity, but high enough to repay the capital cost and deliver a return to investors. Your organisation can either host a project, if you have got suitable roof space, or help finance a project.

In future, there may also be an 11th option, if peer-to-peer energy trading becomes a reality. This allows producers of renewable energy to sell any surplus they have to others directly, rather than having to go through a corporate retailer, via powerful online trading platforms that handle all of the complexities of each transaction.

To compare these different options to one another, you can apply two main tests:

  • Does it meet your organisational needs?
  • What do the financials look like?

This may be a simple or a complex assessment depending on your situation. You may need to take into account your environmental objectives, staff and customer needs and perceptions, your supply chain, ongoing effort or input, and energy market considerations, and other factors relevant to your situation.

To help you get started we have summarised some of the main attributes and issues to consider. These are tabulated below. Remember, your choices to green your electricity supply are not “either-or” decisions, but can be mixed and matched to get you the best outcome.

While the qualitative and financial analysis of your options can be complex, Australia’s renewable energy and carbon markets are mature and a wide range of support is available to assist. You can obtain much of the information online, from industry bodies or government organisations. Energy market experts, solar suppliers, brokers and consultants can complement your purchasing and senior management expertise to help you take decisions that are the best fit for your organisation.

Australian states, territories and local governments leading the way on renewables and climate commitments



Ambitious climate action commitments by states, local governments and communities – Sep 2020


We started tracking the commitments of states, territories and local governments in 2014 when we developed the Renewable Energy Master Plan for Lismore City Council. It was only three years ago, but back then, there were few pledges to ambitious carbon reduction or renewable energy targets. There was the ACT Government’s commitment to 100% renewable energy by 2025[1], and the commitment of two small Victorian towns to go fully renewable.

Lismore Council was the first regional council to make an ambitious pledge to self-generate all of their electricity needs from renewables by 2023. Since then, a lot of councils have followed suit. This is a trend that is being replicated across the world. While there might not always be support for a more sustainable energy future on a national level, at both states and local government levels, there is significant action to help combat climate change.

What follows are three tables that showcase the commitments of states and territories, followed by Australia’s capital cities, followed by local governments.

Local governments with mid-scale developments

In this section, we want to capture where local governments look at mid-scale developments. These are renewable energy installations that range from 0.5MW to roughly 10MW in size. The energy output from these plants is meant to cover the operational energy needs of a council but could be oversized to also cover the needs of the community. 2017 is only the start for mid-scale developments, but we predict that this market will have huge potential going forward.

Electricity prices are going up, the price for renewables has fallen sharply, and the price for LGCs (Large-Scale Generation Certificates) is high. Selling these Renewable Energy Certificates provides a secondary income stream for councils that used to rely on ratepayers only for their income. We used to think that 2020 was the year that it would make sense for councils to develop mid-scale power plants. However, prices for renewables have fallen much more rapidly than predicted, such that it makes sense for councils to look at this opportunity now.

Entity Mid-scale and similar noteworthy developments
Sunshine Coast Council Valdora solar farm, 15 MW, under construction
Newcastle Council EOI for 5MW Summerhill solar farm on capped landfill site
City of Fremantle 2-10MW solar farm on former South Fremantle landfill site is being investigated by the City of Fremantle
ACT As part of its 100% renewable energy commitment, the ACT has facilitated the construction of three solar PV farms within the ACT, including Royalla (20 MW), Mt Majura (2.3 MW) and Mugga Lane (13 MW) via its reverse auction process.

[2] Australia’s Renewable Energy Target (RET) is a Federal Government policy that ensures that at least 33,000 GWh of Australia’s electricity comes from renewable sources by 2020, which roughly equals 20%.

Book trailer ‘Energy Unlimited’

If, as a society, we are to meet the Climate Agreement that was signed in Paris in 2015, we need to reach zero net emissions by the second half of this century.

Organisations will play a big part in reaching this milestone. As part of their sustainability commitments and to combat rising electricity prices, organisations have steadily implemented energy efficiency measures. However, it is only in the last few years that renewables have come down in price sufficiently to compete against fossil fuels. The time is now to commit to 100% renewable energy or zero net emissions and to start planning for the transition.

At 100% Renewables, we have helped organisations since 2014 with their journey to a renewable energy future. We want to share our knowledge with the world, so that more organisations can feel confident in making the switch. We packed everything we know into a book, which details the four-step-method on how organisations can transition to a renewable energy future.

How the average council can save ratepayers $1m per year

1 million dollars

100% Renewables undertook an investigation of how much regional councils spend on electricity, street lighting and fuels, on average. The results are that a typical rural council in NSW spends about $2.5m per year on electricity, $250,000 on street lighting electricity and roughly $1m on fuels like diesel and petrol.

By implementing energy efficiency measures like switching to LED lighting, upgrading to Variable Speed Drives, engaging staff, changing procedures, upgrading building envelopes or installing sub-metering, the average council can save about $0.5m per year.

Making street lighting more energy efficient can save the average council $125,000 per year, and this is just the energy saving. There may be additional savings in Street Lighting Use of System (SLUOS) charges. Through measures like smaller vehicles, car pooling and driver training, another $100,000 per year on fuel costs can be saved.

Installing solar PV behind-the-meter can reduce council’s electricity bill by about $250,000 per year. All reduction measures together are able to decrease energy spend by about 25%. ‘The average regional council in NSW can save about $1 million by implementing a long-term sustainable energy plan’, says Patrick Denvir, co-founder of 100% Renewables.

Some forward-thinking councils have already achieved amazing reductions in their energy bills and their carbon footprints, with some having decreased their consumption by 20%, to even 50% in some cases. While many councils have already embarked on a journey of energy efficiency and implementing renewables, more work can be done.

In our experience, the investment needed to achieve the 25% in savings is between $5m and $6m.  Most likely, two-thirds of these savings can be achieved in the first 5 years of implementing a sustainable energy plan. The last third can be achieved over the longer term.

If you are a council that wants to unlock these savings and save your ratepayers $1m per year, come and talk to us at 100% Renewables. We are specialised in developing long-term energy efficiency and renewable energy plans and can provide advice about how you can access those savings. Call us at 1300 102 195.
