Mannum Solar Farm Greenlit | Murraylands Solar

The 5MW Mannum Solar Farm in the Murraylands will be built by Tetris Energy, and has been approved by the local government. 

Mannum Solar Farm

The Mannum Solar Farm will be 5MW in size, generated by 17,500 solar panels. It will also include a security fence and vegetation screen to ensure neighbouring property owners aren’t disturbed (sometimes we hear about glint and glare when there is solar farm opposition). The farm will be across the road from the Rivapak onion packaging facility. 

An article in the Murray Valley Standard noted that over 8000 households in the Murraylands area have solar panels installed on the roof of their properties – so it’s an amazing area which shows that South Australian solar is continuing to grow domestically and commercially.

Tetris Energy, based in Melbourne, will develop the site. They have already successfully developed 10 solar and wind power plants across Australia so they have a good pedigree – and they have also already secured a purchaser of all 5MW of the power (not named) – but this is obviously a fantastic boost for the farm and will ensure it gets built quickly. The proposal had been approved last April, but had the number of solar panels slightly reduced (in the November application) so they don’t overshadow each other. 

Murraylands Solar Farms

There are already three other solar farms in the Murraylands area:

Clean Energy Council chief executive Kane Thornton discussed solar uptake in the Murraylands in the Murray Valley Standard:

“Homes with rooftop solar installed are saving an average of about $540 per year on their electricity bills,” he said.

“Solar is a clear way for consumers to take control of their power consumption and cut costs, and it’s growing quickly by word of mouth.” Mr. Thornton continued.

Clare solar farm in North Queensland now online.

The Clare solar farm, Queensland’s biggest solar farm at 100MW capacity, has connected to the grid and started exporting renewable energy. This is one of many solar projects due in 2018, totalling around 1400MW.

About the Clare Solar Farm

The Clare solar farm project is located around 35km south-west from Ayr in North Queensland. It’s the biggest operating solar farm in the state, dwarfing the incumbent 50MW Kinston solar project. It is owned by Lighthouse Solar who also have ownership of the Hughenden solar farm which has a 20MW capacity and is about to begin production itself. 

We wrote about the Clare solar farm last July when it was a 125MW plant potentially going up to 150MW. It’s been launched with 100MW with the space to potentially expand down the track. They’ve signed a Power Purchase Agreement (PPA) with Origin Energy along with the Bungala solar farm, which will be the biggest solar farm in Australia when it completes later this year.

According to the Clean Energy Council, around $2.6 billion of solar projects will be connected to the grid in 2018, adding around 1400MW of capacity. A solar forum held in Brisbane by the CEC last week noted that the boom in solar investment (both domestic and commercial) has led to 2760 Australian solar jobs added to the economy. 

“Large-scale solar has gone from an emerging technology in Australia at the beginning of the decade to a genuinely game-changing form of power that is cheaper than new coal or gas. It has exceeded the expectations of even the most optimistic predictions,”  CEC chief executive Kane Thornton said in comments to RenewEconomy.

“Along with the national Renewable Energy Target, support from the Queensland Government, the Australian Renewable Energy Agency and the Clean Energy Finance Corporation has helped to make this one of the lowest-cost options we have for electricity today.”

Large scale solar in NSW to explode in 2018.

Large scale solar in NSW under the Berejiklian government is about to kick up a notch, as 11 large-scale solar energy plants have been approved in the last 12 months. 2018 is also off to a great start with the 500,000 PV solar panel, 170MW Finley Solar Project in the Riverina being approved.

NSW Energy Minister Don Harwin contends that NSW is helping lead the charge (for our money South Australia and Queensland are well ahead right not, but in any case) for solar power in Australia: 

“These projects will ensure our energy security and with many more in the pipeline, NSW is in a stronger position than other states,” he said.

Although NSW only has half the amount of rooftop solar PV as Queensland and South Australia (15% as opposed to 30%) – these figures are definitely a step in the right direction.

 According to Planning Minister Anthony Roberts quoted in the Sydney Morning Herald, 1800 jobs have been created and the ten solar plant approvals in 2017 were double the 2016 number: 
 
The solar plants “collectively reduce carbon emissions by over 2.5 million tonnes, which is equivalent to taking around 800,000 cars off the road”, Roberts said. 
 
Estimates from the Smart Energy Council (an amalgam of the Australian Solar Council and the Energy Storage Council which occured late last year) project that 1.4GW of rooftop solar and 2.5-3.5GW of solar farms will be added to Australia’s solar arsenal in 2018, a massive increase from the record 1.3GW for both rooftop and solar farms that we saw in 2017. 

“With some of the best sunshine anywhere in the world and lots of good locations available, it is not surprising that NSW is up there with Queensland as one of the national frontrunners for new large-scale solar power projects,” Kane Thornton, chief executive of the Clean Energy Council, said.

Solar Powered Trams in Melbourne / VRETs

Victoria has been working on a plan for solar powered trams over the past year and it looks like the Andrews government has moved one step closer with the project – announcing plans to build two new Victorian solar farms to power Melbourne’s tram networks. If that phrase conjured up the image of a bunch of trams with solar panels on top, unfortunately not yet – but using renewable energy to power public transport is a great step forwards. We already have projects like the Valdora solar farm run by the Sunshine Coast Council to power all their energy needs so it’s very encouraging to see the public sector moving in (some semblance of) lockstep with private innovation and investment. 

Melbourne’s Solar Powered Trams

Premier Daniel Andrews announced that Bannerton Solar Park and the Numurkah Solar farm have won tenders to provide renewable energy to power Melbourne’s trams, offering 100MW and 38MW respectively for the network. The $100m Bannerton project will consist of 95,000 solar panels and is expected to reach full completion by July 2018. The Numurkah Solar Farm will output 100MW via 300,000 solar panels on 500 hectares, but only 38MW of this will be going to the government. French solar plant developer Neoen (who will partner with Tesla to create the world’s largest lithium-ion battery in South Australia) will commence construction in early 2018.

In January Energy, Environment and Climate Change Minister Lily D’Ambrosio advised that they would use one solar plant with 75MW of power – and that half of this would go to the tram network as 35MW was sufficient to cover the energy needs of 410 Melbourne trams. Despite opposition energy minister David Southwick decrying it at the time as a ‘media stunt’ and said Andrews’ government should be ‘fighting for the most affordable power deal for Victorians’, the government has forged ahead and have doubled down on their renewable energy plans – announcing Victoria’s Renewable Energy Targets for 2020 and 2025. 

Victorian Renewable Energy Target

Legislation introduced to Parliament (the first time RETs have been enshrined in state legislation in Australia) last week has set Victoria’s RETs (Renewable Energy Targets) to 25% at 2020 and 40% by 2025. According to the Herald Sun, they haven’t released any modelling showing what the figures are based on, but the RET will mean a cut to energy prices of $30 p.a. for an average family. 

According to Andrews, “The VRET will cut the average cost of power for Victorians by around $30 a year for households, $2,500 a year for medium businesses and $140,000 a year for large companies, while driving a 16 per cent reduction in Victoria’s electricity sector greenhouse gas emissions by 2034-35.”

The VRET legislation allows for a competitive reverse auction (i.e. the lowest bidder wins) for up to 650MW of power (enough to power Geelong, Ballarat, Bendigo and the Latrobe Valley combined) , which Clean Energy Council chief exec Kane Thornton says will ‘turbocharge’ the renewable energy industry in Victoria, calling it a ‘major step forward for communities, businesses and the state’s renewable energy industry’. 

Political grandstanding or a massive step forward for renewable energy in Victoria? Is it necessarily a zero-sum game? We’ll know very soon – watch this space and we’ll keep you updated on how things are going! With the first legally binding state RETs Victoria are certainly putting their money where their mouth is and doing their bit to reduce emissions and move towards a renewable energy future.

Redback Smart Hybrid System / EnergyAustralia

Queensland based solar company Redback Technologies have teamed up with EnergyAustralia to offer a “next generation” smart solar plus storage system, named the Redback Smart Hybrid – which is slated to pay for itself within seven years.

According to the Australian Financial Review, the system will utilise smart technology to optimise use of solar panels and batteries depending on usage and weather patterns. It’ll also have an app which allows users to remotely control and monitor operation of the Redback Smart Hybrid system.

Estimates from EnergyAustralia say that a normal household with usage of 8000kWh / year will save around $1,500 a year with the Redback Smart Hybrid system (4.9kW solar array and 3.3kWh battery). That system would cost around $9,000, or $7,000 to retrofit to existing panels with some modifications to the inverter. One of the main bonuses of the system is that it’s modular – so customers are able to scale up if they’re interested in expanding. It makes use of the Redback Smart Hybrid Solar Inverter which is designed in Brisbane, and different batteries / solar panels depending on your circumstances.

Kane Thornton, CEO of the Clean Energy Council called the system an example of the “game-changing” tech currently coming out to help combat rapidly rising electricity bills.

Andrew Perry of Energy Australia was circumspect to the AFR about specific sales goals for the system, but did advise that they have “strong ambitions for growth”. It certainly seems like we are heading very quickly to the point where solar + storage is a no-brainer for certain types of consumer – especially with the ‘smart technology’ removing the need for spreadsheets and PhDs for those wanting to get a strong result from their solar investment. To get a system like this for under $10,000 is a great deal – we’ll be very interested to see how sales go over the coming months.

Redback Smart Hybrid vs Tesla Powerwall

Technically the Redback Smart Hybrid is just an inverter + smart energy management system, but the Smart Hybrid system being offered by EnergyAustralia is an ‘all in one’ system. In comparison to the Powerwall which is just an inverter + storage,  it’s a bit difficult to compare them fairly. It is important to note that given the modular design of the Smart Hybrid, you’re able to ‘start off small’ with a 3.3kWh battery (as opposed to the Powerwall 2, which you can also add to, but only in increments of 13.4kWh) and grow from there.

The PowerWall is significantly more expensive than the Redback, and doesn’t include solar panels. However, if money is less of an issue and you’re prepared to wait, the Tesla Solar Roof Australian release date is currently “early 2018” and will undoubtedly be a premium solution for those who are interested in aesthetics along with quality.

It seems that both systems have their own niche depending on how much one wants to pay – but you certainly couldn’t be faulted for taking a look at the Redback Smart Hybrid price point and being impressed. If the smart tech works like they say it does, it’ll be a very powerful contender against all comers. Not having to worry about compatibility is definitely a big plus – although the battery / panels used may differ depending on your circumstances, EnergyAustralia will ensure the system fits together nicely.

The Redback / EnergyAustralia Partnership

EnergyAustralia invested $9.3m into Redback Technologies last October – their first major investment. The two companies have been working together on various projects including back in April where they inked a memorandum of understanding (MoU) to bring Redback’s solar tech to Dubai South for a pilot project.

Have a look at the video below which introduces Redback Technologies, their founder and MD Philip Livingston, and explains more about their partnership with EnergyAustralia.
