How does renewable energy lower energy prices?

In Australia, record levels of renewable energy have driven down electricity prices and reduced consumers’ need to access the grid for power.

In an interview with news.com.au, Victoria University energy expert Associate Professor Bruce Mountain explained that Australia’s energy system is complex and impacted by many factors. However, he said it was fair to say that the spread of solar panels on rooftops and the addition of new solar and wind farms to the grid meant spot power prices were often zero during the middle of the day, and regularly lurched into negative territory.

This has created the situation where coal-fired power stations actually pay the market to dispatch their electricity, rather than being paid for it.

“Because that’s cheaper than switching off [the power station] and having to restart again,” Prof Mountain said.

Interest rates unlikely to rise next year
While inflation has risen in Australia due to increased demand for goods rather than services and global supply chain impacts during the pandemic – the overall effect has been modest in comparison to international markets and is predicted to moderate over the next 18 months.

Mr Lowe said the latest data and forecasts do not warrant an increase in the cash rate next year.

“The economy and inflation would have to turn out very differently from our central scenario for the Board to consider an increase in interest rates next year,” he said.

Join the solar revolution

With summer just around the corner, we’ll soon be cranking our air conditioners and cooling off in our pools – two extremely energy-intensive features of many homes. Not only does solar compensate for that hefty energy usage but, during summer, solar systems can generate twice the electricity than in the short days of winter.

Is Tesla Powerwall Economically Feasible in Australia?

Tesla has selected Australia as one of the first countries to install the updated Powerwall Battery solution (Powerwall 2.0 system) due to its tariff structure, high solar radiation values, and high electricity prices. The Powerwall 2.0 stores double the energy (13.2 kWh), is 30% smaller in size and similar in cost.

The Powerwall 2.0 system can be used for load-shifting in which energy management is used to move demand from on-peak to off-peak hours. In other words, the Powerwall 2.0 system is charged by the household or business grid during the off-peak tariff hours and discharged back into the same grid in the on-peak tariff hours. The difference between the two tariffs represents the savings that are then used to pay back the investment and eventually make a profit on the investment. The Powerwall 2.0 system may also be used for PV production storage to be used in the nighttime where household electricity consumption is highest, and/or just for backup power.

Battery Capacity

With 13.5 kilowatt-hours of usable storage, the Powerwall 2 has over twice the capacity of the original, which could store 6.4 kilowatt-hours when new.

Too Much For Most Aussie Households 

The average Sydney household without gas uses an average of around 17.6 kilowatt-hours a day and perhaps half that overnight. This means only very large or very wasteful households are likely to be able to use a Powerwall 2 at full capacity for ‘solar shifting’ and so get the best possible return on the battery system.

How Much Does The Tesla Powerwall 2 Cost in Australia ?

In Australia, across our network of over 150 solar installers, we expect this installed cost of a Tesla Powerwall 2 to cost between $14,000 and $16,000 excluding Solar Panels and any rebates that might be available in your state.

The economic feasibility of the investments of each of the four scenarios is determined by calculating the economic methods such as the Discounted Payback Period, the Net Present Value, the Internal Rate of Return, and the Profitability Index. Tesla has announced the impending arrival of the Powerwall 2 at a promised price point that, on the surface, looks very compelling: $10,150 fully installed1.

Tesla Powerwall payback

It is difficult to beat the return on a term deposit by installing a Powerwall 2 using my assumptions, but it can be done provided a household’s electricity consumption is extremely unusual and time-of-use tariffs remain as high as they are now.  Even if you are confident you can use most of a Powerwall 2’s output during peak periods, you will still be at the mercy of changes in electricity prices that are out of your control. So you will not only have to be unusual, you will also have to be lucky.

Payback times will be different for every household, but in some instances it seems the payback time may well exceed the warranty period for the Powerwall. If your intention is to have the Powerwall paid off by your electricity savings, then you might want to chase a further guarantee from your installer that the unit will last that long.

What’s also clear is that tapping into your own solar power as much as possible, rather than feeding it back into the grid with a measly feed-in tariff, will decrease your payback time.

These are just simple calculations to give a rough estimate of the potential payback time. There are a range of factors that can influence the outcome, including increases in electricity prices and ongoing maintenance costs, which you might want to factor into your own calculations.

How to select the best solar panel for home

Solar PV systems can be classified based on the end-use application of the technology. There are two main types of solar PV systems: grid-connected (or grid-tied) and off-grid (or standalone) solar PV systems

A solar PV system is powered by many crystalline or thin-film PV modules. Individual PV cells are interconnected to form a PV module. This takes the form of a panel for easy installation. The cells contain in solar panels convert sunlight into Direct current (DC) electric power. The DC output of the solar cell depends on multiple factors including environmental and technical. Low efficiency reduces the output of solar panels and it reduces the ROI of the solar system.

When installing a solar system, house owners mainly look into these key points: efficiency of solar panels, aesthetic of solar panels, cost of the solar system, and professional installation.

The efficiency of solar panels

Two key cost drivers are the efficiency with which sunlight is converted into power and how this relationship changes over time. Solar installers offer monocrystalline panels to set up a solar energy system in a normal household. Monocrystalline panels are the most efficient solar panels compared to other technologies. Solar modules (and cells within) need uninterrupted sunlight to produce maximum electrical energy. With the shadow even on a part of the module, the generation reduces to a great extent thereby wasting installed system capacity.


Solar Panel Cost in Brisbane

The cost of your solar PV system will depend on many factors: system configuration, equipment options, labour cost and financing cost. Prices also vary depending on factors such as whether or not your home is new, and whether the PV modules are integrated into the roof or mounted on the roof. The cost also depends on the system size or rating, and the amount of electricity it produces. There are many professional solar installation companies in Brisbane. These companies offer different types of packages that come with 3.3kW, 6.6 kW, 10kW. Apart from these solar installation packages, you can customize as per your power usage.

Generally, solar PV systems installation cost is high. You can save money on your electricity bill. But even with these savings, it will take a long time to recover the capital cost of the solar PV installation. The Australian government is providing rebates for solar system installation. The maintenance cost very low, also solar panel companies are providing 10 years manufacturer’s warranty and 25 performance warranties.

Aesthetic of solar panels

The important thing to bear in mind is that if you are considering installing solar panels on your property you do have options about how the solar panels will appear. Contact a professional installer and request for a site visit. You will get more ideas about the aesthetic part of the solar system.

Regular maintenance of the solar system

During the defect liability period (usually for 12 months after installation), solar PV system contractors usually use remote monitoring data to prepare monthly performance reports of the installed solar PV system. They should come on site to rectify any problems flagged by the remote monitoring service.

Professional installation

Always select a professional solar system installation. Check the Licensing and Certification for the installer. Go through the customer reviews in different portals.

What type of solar panel is suitable for the home solar system?

home solar system

The majority of residential solar modules consist of PV cells made from either crystalline silicon cells or thin-film semiconductor material.  Crystalline silicon cells are further categorized as either monocrystalline or polycrystalline. The monocrystalline cells provides high efficiencies (13–19%) but are more expensive and difficult to manufacture. Polycrystalline (also called multi-crystalline) silicon cells that have lower efficiencies (9–14%) but are less expensive and easier to manufacture.

Soar panel brands and professional installation also major factors that affect the overall efficiency of the solar system. Below are the three types of technologies used for residential solar panels.

1. Monocrystalline Silicon Solar Cells

Monocrystalline silicon solar cells are made from a very pure type of silicon which makes them most unique. They are most efficient in their output so they are also most space efficient. This is understandable as fewer cells would be required to produce the electrical output of one unit. The edges of cells in monocrystalline solar panel are cut off to increase efficiency level and reduce maintenance. Monocrystalline Solar Panel have blackish color on its surface. The solar panels which contains monocrystalline solar cells are expensive compared to other types of solar panels.

2. Polycrystalline Silicon Solar Cells

Unlike monocrystalline cells, polycrystalline cells do not go through the process monocrystalline goes through. As an alternative, the silicon is emptied into a four-sided mold after being melted this gives the square shape to polycrystalline. Characteristically, polycrystalline solar Photovoltaic system operates at efficiency of 13-16%. This is due to lower purity of the material. Because they are less efficient, these types of solar cells are also less space efficient so they require a lot of panels for small electrical power. Another disadvantage of these solar cells is that it tolerates less heat than monocrystalline, this means they are not as efficient in high temperatures and do not perform efficiently.

The price gap between monocrystalline and polycrystalline panels is narrowing. Now, more homeowners are willing to pay a slightly higher price to get significantly better efficiency and power ratings from monocrystalline panels.

3. Thin Film Solar Cells

They are another type of solar cells. They exist in many types but their efficiencies lie from 7 to 13%. Many experts say that their efficiencies will climb up to 16% in future models due to the research and advancement being. They are made by coating numerous types of semi conducting materials with silicon. In some of the cases they are coated on top of each other to make a sequence of thin films. The production of these solar cells on a very large scale is easy when we compare them to monocrystalline and polycrystalline based modules. This decreases their price of production. There are two disadvantage for thin film solar panels. First disadvantage is, more rooftop space is required because of less efficiency. Second disadvantage is durability. It is not durable compared to silicon solar cells.  Thin film solar cell based solar panels are mainly using for commercial solar systems and solar farms projects.

Other type of solar Cells used for commercial solar system and solar farm projects

Amorphous Silicon Solar Cells

Thin film solar cells which are made up of amorphous silicon are utilized in smaller applications like handheld calculators, lights used while traveling and picnic camps used in far areas. Due to forming multiple layers of this material which is a new process the efficiency for these technologies have been recorded up to 8%

Cadmium Telluride Solar Cells (CdTe)

The lone thin film material which has given competition to the crystalline in terms of cost is this type. It has efficiency in the range of 9-11%.

Copper Indium Gallium Selenide Solar Cells

Copper Indium Gallium Selenide Solar Cells are the only type of thin film technology which has efficiency compared to crystalline technologies, i.e. 10-12%

Key Points

  • There are three mainly three types of technology used in solar panels:  monocrystalline, polycrystalline, and thin film.
  • Monocrystalline solar panels are highly efficient and comes with latest design, it is expensive compare to polycrystalline and thin film.
  • Polycrystalline solar panels are cheaper than monocrystalline panels, however, they are less efficient. Required more roof space and appearance is not good as monocrystalline. 
  • Thin film solar panels are the cheapest, but have the lowest efficiency rating and require a lot of space to meet your energy needs.

HyEnergy Project to boost Australia’s green hydrogen exports

HyEnergy Project to boost Australia’s green hydrogen exports

Green hydrogen produced from renewable sources, such as wind and solar energy, looks set to play a significant role in navigating society towards a decarbonised future and meeting the global aim of net zero emissions by 2050.
The HyEnergy Project is a potential ‘Renewable Green Hydrogen Project’ by Province Resources that is located in Western Australia’s Gascoyne Region just south of Carnarvon.
On account of climate commitments, nearly half the globe has already embraced net zero policies. For climate experts, green hydrogen is indispensable to climate neutrality. It seems Australian markets are hungry for hydrogen and were badly on the lookout for something other than fossil fuels to keep the exports alive. Province Resources’ have made a right move in this direction as there is a huge demand for green hydrogen and Australia is trying to be its key exporter.
Province Resources is a gold and nickel exploration company formerly known as Scandivanadium. With the “news” of its green hydrogen project, the stock price of Province Resources leaped 262% that it could be even the top pick of the year.
It is proposed to acquire Ozexco Pty Ltd in the Gascoyne. It is subject to shareholder approval at its general meeting. Ozexco holds seven license applications, hence suitable for developing a renewable green hydrogen project.
Vulcan Resources’ co-founder and CEO Francis Wedin has invested in Province Resources and is signed on an advisor to the company. Vulcan has developed the world’s first and only zero-carbon lithium process and plans to produce battery-grade lithium hydroxide from geothermal brines pumped from wells with a renewable geothermal energy by-product.
The company’s vision is to generate 1 GW of renewable energy in Western Australia using wind and solar and to produce approximately 60,000 tonnes of green hydrogen or up to approximately 300,000 tonnes of green ammonia.
The next 12 to 18 months will see Province Resources commencing feasibility studies for renewables generation and hydrogen production at the HyEnergy Project as well as execute a deal with an independent power producer to develop the clean energy needed. The firm will then initiate discussions with potential offtakers.
Why Gascoyne?
World class wind and solar resources of the Gascoyne Region within close proximity to key infrastructure provides potential for the establishment of a Renewable Green Hydrogen Project capable of supplying domestic and international markets. Gascoyne has the highest solar irradiance and is the fourth windiest location in WA. Gascoyne’s climate and wind patterns made renewable energy an attractive and viable option.
The proposed site is not far from Dampier Bunbury Natural Gas Pipeline as well as export infrastructure, which will certainly prove helpful. WA’s geographical proximity to Asia and its longterm presence in these markets is another strategic benefit.
With an area of 2.5 million sq km WA is well placed to develop large scale renewable energy generation sector. WA’s low intensity land use and low population density makes the project area ideal for installation of a commercial scale wind and/or solar farm.
Since Australian government dreams of being a major green hydrogen exporter, the funds for Province’s HyEnergy Project will be taken care of by country’s emergent green hydrogen industry. Funding from Government on both a State and Federal level include:
• Western Australian Renewable Hydrogen Strategy $10m.
• Australian Renewable Energy Agency (ARENA) $70m.
• Australian Government Advancing Hydrogen Fund $300m.
Green hydrogen produced from renewable sources, such as wind and solar energy, looks set to play a significant role in navigating society towards a decarbonised future and meeting the global aim of net zero emissions by 2050.
Launching its Renewable Hydrogen Strategy last year, the government of Western Australia announced its aim to become a “significant producer, exporter and user” of green hydrogen. The strategy said Australia’s zero carbon green hydrogen exports could reach AU$2.2 billion by 2030.With HyEnergy project, Australia is making a move in this direction.

Morgan-Whyalla Pipeline to be solar powered

Morgan-Whyalla Pipeline to be solar powered

SA Water delivers safe, clean water and dependable sewerage services. It is a corporation owned by the people of South Australia, and are committed to providing their 1.6 million customers with trusted water services that represent excellent value.
SA Water plans a zero-cost energy future by powering its largest drinking water pipeline, Morgan–Whyalla Pipeline, with 19,000 solar panels, which is capable of generating 14,000MW/h of clean, green energy. The solar panels are located at the pipeline’s third pump station in Geranium Plains and is participating in the National Electricity Market.
From SA Water’s Morgan Water Treatment Plant, this concrete pipeline transports treated, high-quality drinking water from the River Murray across to the Upper Spencer Gulf region, which is around 358kms.
To track the sun from east to west throughout the day, solar panels are constructed on a pivoted racking system. These solar panels will help reduce SA Water’s operational costs by harnessing green energy and thereby reducing the pumping expenses without affecting the pump station’s overall performance.
The direct current (DC) voltage captured by the panels is converted into high-voltage alternating current (AC) energy, where it travels underground to a connection point for use at the pump station. Any excess electricity generated at the site can be sold back to national grid.
SA Water has already installed more than 500,000 solar panels across the state at various sites including Bolivar Wastewater Treatment Plant and the Adelaide Desalination Plant. These produce a total of 242 GWh of green energy each year. The positive impact of their zero-cost energy future project has led to a total emissions reduction equivalent to planting more than seven million trees or removing more than 30,000 motor vehicles from the road every year of operation.
“Given the Morgan to Whyalla Pipeline is responsible for delivering clean, safe drinking water to tens of thousands of our customers from the Riverland, Barossa, Mid North and Upper Spencer Gulf regions, the energy requirements to pump such volumes of water are significant,” SA Water Senior Manager Zero Cost Energy Future Nicola Murphy said.
“The array is one of four being installed along the Morgan to Whyalla Pipeline, with a further 15,000 solar panels at the fourth pump station outside Robertstown aiming to be energised by mid-2021,” she said.
SA Water’s electricity cost for 2019-20 was approximately $86 million. Their extensive water and wastewater operations makes them one of South Australia’s largest electricity consumers. Increasing their renewable energy generation is the only way to sustainably reduce their operating expenses. Only that will help them keep prices low and stable for their customers. The plan to power the Morgan-Whyalla Pipeline with solar is definitely a move in this regard as well as a positive move by SA towards achieving a zero-cost energy future.

Perovskite solar cell developed with superpower conversion efficiency

Perovskite solar cell

Perovskite solar cell developed with superpower conversion efficiency

Researchers say Solar module manufacturers should begin testing new technologies in higher-value niche markets. Only such markets can bring cutting-edge PV technologies such as perovskites to commercial maturity. Though it might seem prohibitive in mainstream market in terms of initial investment, segments like building-integrated PV or microelectronics devices can offer commercial maturity.

Perovskite solar cell with a power conversion efficiency of 25.2% have been fabricated by the researchers at the Massachusetts Institute of Technology (MIT). It is developed through the chemical bath deposition method. CBD is a technique to produce films of solid inorganic, non-metallic materials on substrates by immersing the substrate in a precursor aqueous solution. Thiourea (TU) is a compound used in thin-film solar cells to achieve high-quality films in the film-deposition process.

If the conductive layer is directly attached to the perovskite, there will be no current flow as the electrons and their counterparts, called holes, simply recombine on the spot. If the perovskite and the conductive layer are separated by this intermediate layer, the latter lets the electrons through and prevents the recombination.
The US scientists added a special conductive layer of tin dioxide bonded between the conductive layer and the perovskite material. The special conductive layer was treated with a chemical bath at 90 degrees Celsius, which made the precursor chemicals slowly decompose to form the layer of tin dioxide in place.
Having understood the decomposition mechanisms of these precursors, the researchers were able to find the right window in which the electron transport layer with ideal properties could be synthesized.

Depending on the acidity of the precursor solution different mixtures of intermediate compounds form and it produce more effective films. The perovskite layer is further improved by adding special additives that do not alter the material’s bandgap. The positive effect of this special conductive layer when combined with an improvement of the perovskite layer has resulted in the development of perovskite cells that boost efficiencies. The achieved conversion efficiency of the solar cell was thus far demonstrated in tiny lab-scale devices. Even with a single active layer, we can make efficiencies that threaten silicon.

Advantages of perovskite solar cells:


• It increases efficiency and lowers the cost of solar energy.
• It has low potential material & reduced processing costs.
• It can react to various different wavelengths of light, which lets them convert more of the sunlight that reaches them into electricity.
• It offers flexibility, semi-transparency, tailored form factors and light-weight.
Disadvantages:
• They degrade when exposed to heat and moisture.
• They are less durable than silicon ones, which have lifetimes of more than 25 years.
Perovskite solar cells offer the tantalising possibility of higher energy efficiency and faster manufacturing than regular commercial silicon panels. Researchers have scaled up perovskite cells before but they aren’t commercially viable yet.
Perovskite solar cells are the most emerging area of research among different new generation photovoltaic technologies due to its super power conversion efficiency.

Lightweight, flexible solar applications on demand

home solar system

Lightweight, flexible solar applications on demand

The booming market demand and the expansion of bifacial module applications has caused a shortage of solar glass and it is one of the problems that PV manufacturers are facing. This results in an increase of solar glass prices by up to 40%. As the module producers are not able to supply, they have to lock in supply contracts.
Bifacial modules produce solar power from both sides of the panel. It exposes both the front and backside of the solar cells. Bifacial modules come in many designs – framed, frameless, dual-glass, clear back sheets, monocrystalline cells, polycrystalline designs. The one thing that is constant is that power is produced from both sides.
Dual-glass bifacial modules dominate the market. As its more in demand, glass makers couldn’t keep pace with the supply, hence this shortage and increase in price.
Bloomberg NEF confirms that PV glass prices have increased by 75% between July and November 2020, due to this shortage. It notes that the shortage is particularly pronounced for 2mm glass used in dual-glass modules.
Due to various policy measures taken by Chinese administrators and suppliers glass production is expected to be over 35% in 2021 and the glass price to be back as before by the first half of the year.
With the prevailing shortage of glass modules, Shi Zhengrong now heads up the module startup Sunman who produce lightweight modules by encapsulating crystalline silicon (c-Si) solar cells in a polymer composite material. It weighs 5.8kg with a 5.6mm frame and 8.1kg with a 35mm frame – both in a 60-cell configuration.
The lightweight Sunman modules have ample opportunities for rooftops in sunbelt regions, such as Southeast Asia or southern China, where roofs are not constructed for weight bearing. Light weight modules have an advantage over traditional glass modules as it aptly fits lightly structured commercial rooftops which cannot handle much weight.
Sunman has shipped approximately 50 MW of modules over three years and is anticipating that its annual shipments will grow to 40 MW in 2021.
Non-crystalline PV technologies such as thin films, like amorphous silicon, dye-sensitised solar cells, copper indium gallium selenide (CIGS) PV, and organic PV (OPV) are supplied for rooftops not available to glass modules.
To produce such modules, the semiconductor material, either stainless steel or polymer is deposited onto a flexible substrate through slot-printing or ink-jet processes. Evaporative deposition has also been used for higher-efficiency thin films.
Roll-to-roll (R2R) production is a very mature technology and is more attractive due to high throughputs. In R2R production the substrate can be unwound, passed through the processing steps and rewound. R2R is the predominant process for flexible thin film production. It accounts for more than 90% of output at present
Global Solar and MiaSolé, the CIGS manufacturers have deployed huge volume of R2R flexible thin film production. Though they could make a good track record of efficiency improvements, they couldn’t scale cost effectivity.
Apart from CIGS, amorphous silicon and OPV developers have also applied R2R techniques in production. Throughput offered by R2R is promising, but its production processes cannot be optimised in small batches of wafers while c-Si can be done like that.
Sweden’s Midsummer is a flexible CIGS producer and their modules are of high quality with short cycle time and high yield and output. Their CIGS cells are cut from the stainless-steel substrate before processing, and then assembled into modules. It applied its founders’ experience in optical disk production to CIGS through its DUO production system. They applied batch PV cell production techniques on a flexible substrate, rather than R2R.
Midsummer produces its flexible CIGS Wave modules in Sweden and is planning a 50 MW production facility in Italy. Its lightweight applications and low CO2 emissions are its highlights.
The company is focusing on southern European markets where commercial and residential roofs are not weight bearing. They have signed agreements with distributors in Spain and Portugal.
In 2020 Midsummer introduced its “PowerMesh” cell interconnection technology in production and its modules now include a bypass diode between each cell, delivering enhanced shade tolerance.
Unlike c-Si producers, it is not easy for flexible thin film producers to achieve conversion efficiency. With its huge production capacity and relatively aligned technological pathways, Crystalline silicon is a formidable rival.

Australia’s largest solar farm to power Singapore

solar power

Australia’s largest solar farm to power Singapore

Solar energy is experiencing a massive transformation in Australia as it is moving into a phase of mass rollouts of large-scale solar farms. World’s largest solar farm is to be built in Australia. This major renewable energy project is undertaken by Sun Cable’s Australia-ASEAN Power Link (AAPL). It is Australia’s largest-ever construction project and is expected to be completed in 2027.
The AAPL plans to integrate three technology groups – the world’s largest battery, the world’s largest solar farm, and a 4,500km high voltage direct current (HVDC) transmission system from the solar / storage facility to Darwin, Singapore, and eventually Indonesia. The developers expect to provide one-fifth of Singapore’s electricity needs, replacing its increasingly expensive gas-fired power.
Sun Cable’s Australia to Singapore Power Link, is an example of the potential of solar for our trade partners overseas. Singapore is an important trade partner with Australia. Since Singapore’s well-regulated electricity market runs mostly on gas piped from Malaysia and Indonesia and shipped as LNG which is very expensive, there will be whole hearted acceptance of this new plan. This new project is good for the environment and very important for the development of business side with Singapore.
This ambitious AUD$20 billion project will be built at a remote cattle station in the Northern Territory, Tennant Creek roughly halfway between Darwin and Alice Springs. It will be located exactly at Newcastle Waters which is a township in Tennant Creek. This massive solar farm will be visible from space after its construction. Casino mogul James Packer’s father Kerry’s 10,000 Sq km property at Newcastle Waters, has been earmarked for this solar farm. It has been found as an ideal location for the project as:
• It’s on the Adelaide to Darwin rail corridor, so it is easy to transport the enormous amount of materials to the site.
• There’s plenty of sun and not many clouds, thus providing ideal conditions for energy production.
• costs of transmitting the electricity from there to Darwin is not too high.
• extremely flat land is ideal for construction of a solar farm.
The project plans to have a 10-gigawatt-capacity array of panels spread across 15,000 hectares. It will be backed by about 22 gigawatt-hours in battery storage to ensure power supply round the clock.
Parts of the electricity generated would be sent through Overhead transmission lines to Darwin and plug into the NT grid. The bulk would be exported to Singapore via 4,500km high-voltage direct-current transmission network, including a 3,800km submarine cable running through Indonesian waters. It plans to provide 20 percent of Singapore’s power demand, with plans to continue on to Indonesia.
Sun Cable’s Australia-ASEAN Power Link project has the potential to be an important part of this nation-building journey. This is a massively exciting project with world-changing potential.
“It is extraordinary technology that is going to change the flow of energy between countries. It is going to have profound implications and the extent of those implications hasn’t been widely identified,” said Sun Cable CEO David Griffin.
The project has won major project status on 29 July, from the Federal Government, which expects to help smooth the approval process. It gained the attention of many multi billionaire investors as well. The mining magnate and philanthropist Andrew Forrest and software tycoon Mike Cannon-Brookes have invested tens of millions of dollars in this project.
The company said the project is expected to provide 1,500 construction jobs and 12,000 indirect jobs during construction, with 350 long-term operational jobs spread between the solar farm site at Elliot and Darwin.
Sun Cable has initiated the project by evaluating its environmental impact .The project has been submitted to the Northern Territory’s Environmental Protection Authority for approval. Once the approval is secured, the land construction is expected to begin in late 2023, energy production by 2026 and export by 2027.
Along with other renewable energy projects, this project would help Australia in being a super power in a carbon constrained world.
The earnest Sun Cable project could serve as an exemplar of Australian ingenuity and leadership. This ambitious export plan could generate billions and make Australia the centre of low-cost energy in a future zero-carbon world.
