SRES – Will solar rebates increase the cost of electricity?

Posted on by — No Comments ↓

Will solar rebates increase the cost of electricity? Yesterday The Australian newspaper published an article titled ‘Households’ $2bn solar hit’ which hypothesises that every Australian household will have to stump up $195 to help subsidise the subsidies. Is this rubbish? What impact does the SRES really have on electricity prices? Let’s read on…

SRES – Will solar rebates increase the cost of electricity?

Ketan Joshi via Renew Economy wrote a great article titled “How a ridiculous falsehood about solar power self-replicated in media”. You can read it on Ketan’s blog (ketanjoshi85) by clicking here. The “$2b solar hit” is a sum which has been basically made up through some extremely shoddy extrapolations.

The article in the Australian was run with by a number of Australia’s most trusted media outlets – News.com.au, 7 News, Sky News, the Today Show, and the consistently atrocious Daily Mail – who titled their article about the rebates thusly: 

“Climate change farce: How every Australian household contributes $200 a year to those lucky enough to be able to afford to put solar panels on their roof”

Energy Minister Angus Taylor decided to blame the big electricity retailers:

‘The big cost is the profits being taken by the big energy companies in the wholesale market, without innovation or new products, and it is time for them to deliver a fairer deal for their customers,’ he said.

‘According to the Australian Energy Market Commission, the small-scale technology certificate cost is less than three per cent of the bill, whereas 46 per cent is going to the big generator retailers.’

The Renew Economy article notes that, for FY18 and FY19 respectively, Australians paid/will pay $19 / $32 towards the scheme. This is a stark contrast to the $134 / $195 which was reported. It appears that the figures are so badly skewed for a number of different reasons including the assumption that 100% of electricity costs are passed on from businesses to households. They also haven’t factored in the Small-scale Technology Percentage, which will be set by the Energy Minister in March – and the effect this will have on STCs is quite marked. Installing solar power systems becomes cheaper if the STCs are higher, so you can see how this would have an impact which could be measured erroneously. It’ll be interesting to see how this impacts on solar grants moving forwards. 

The Small-scale Renewable Energy Scheme (aka SRES) is scheduled to run until 2030. If you’d like to read more about it please visit the Clean Energy Regulator’s website – where they have plenty of information about the scheme. 

We’d also recommend Ketan’s article for a more in depth exploration of the issue.

Recycling Solar Panels | What to do with old solar panels.

Posted on by — 1 Comment ↓

Recycling solar panels is a topic which will be a lot more prevalent as the initial ‘wave’ panels begin to reach their end of life. Let’s take a look at what the plans are for trying to minimise the environmental impact and maximise the value  of a used solar panel.

Recycling Solar Panels | Will there be a waste crisis for old panels?

Australia has one of the highest PV solar uptakes in the world. There are plenty of us who have had solar installed for a long time. So long, in fact, that people are talking about end of life strategies to dispose of/ repurpose solar panels, so that they don’t cause a problem for the environment. 

Total Environment Centre director Jeff Angel has been crusading for the implementation of such strategies for solar panels, calling it a ‘systemic problem’:

“We’ve had a solar panel industry for years which is an important environmental initiative, and it should have been incumbent on government to act in concert with the growth of the industry so we have an environmentally responsible end-of-life strategy,” he said in a quote to the Sydney Morning Herald.

We’ve written previously about solar panel recycling and, although it’s good to see things like the ELSi project in Germany, there’s still a ways to go before we figure out the best way forward to recycle solar waste.

According to the director of Reclaim PV (the only dedicated photovoltaic recycler in Australia), Clive Fleming, they company recycles 90 per cent of materials in a panel. The company has been lobbying for state bans on landfill disposal of solar panels. 

Australian Council of Recycling chief executive Peter Schmigel also had a quote in the SMH about how a proper plan for recycling PV cells could have a positive effect on the economy:

“Recovery rates have been out of sight since the beginning of the scheme, nobody has said anything at all about there being an inbuilt recycling cost. It generates jobs, it generates environmental outcomes and yet for some reason we have policymakers who are hesitant about [establishing similar schemes] for solar PVs and batteries,” he said.

We expect over the coming year or two we’ll hear a lot more about this, with Sustainability Victoria working on a ‘national approach to photovoltaic product stewardship’, with their recommendations presented to the environment ministers around the middle of this year. 

Victoria have already announced they’ll ban electronic waste in landfill from July 2019, so it’ll be interesting to see if/how the other states follow suit.

SolarReserve announced on Tuesday that they’ll work with Heliostat SA to create 12,800 96 square metre glass mirrors for their Aurora Solar Thermal Plant. 

The solar thermal plant in Port Augusta, South Australia, was announced last August and received developmental approval back in January It is slated to be a $750m project but we haven’t heard any specifics as to updated pricing, and this information is the first news on the project since January of this year. 

According to the CEO of SolarReserve, Kevin Smith, the solar thermal power plant will comprise of approximately 12,000 mirrors, each the size of a billboard (around 100sqm), arranged in a circle over 600 hectares. The mirrors will focus light and heat to the top of a 227m tall tower to generate up to 150MW. This will result in over a million square metres of surface area for the project. 

“Aurora will provide much needed capacity and firm energy delivery into the South Australian market to reduce price volatility,” Mr. Smith said at the time. He elaborated today when discussing the deal with Heliostat SA: 

“We’re excited to have formed a long-term partnership with Heliostat SA and look forward to teaming up with them to bring manufacturing of our world-class heliostats to South Australian workers,” said Mr. Smith.

“SolarReserve is committed to supporting South Australia’s goals which will attract investment, create South Australian jobs and build an exciting and growing new industry.”

According to an article on RenewEconomy the project will create around 200 full time solar jobs for the area, with 650 to be employed during the construction phase. 

This project is a bit slow and new information is thin on the ground, so great to hear that it’s moving ahead. We’ll keep you posted as soon as there’s any new information on the solar thermal plant!

Solar and Wind Farms in the Sahara Desert

Posted on by — No Comments ↓

New research in Science magazine shows that installing solar and wind farms in the Sahara Desert could generate massive amounts of electricity and turn parts of the desert green for the first time in over 4,500 years.

Atmospheric scientist at the University of Maryland, Eugenia Kalnay, has been working on this theory for over ten years, postulating that the darkness of solar panels won’t reflect the sunlight – helping heat up the surface of the land – which will in turn drive air upwards into the atmosphere (which, in turn, generates rain). 

Dr. Kalnay talked one of her post-doc researchers into creating a computer simulation where 20% of the Sahara is covered with solar panels. They also tried a simulation where the desert was covered in turbines to generate renewable energy from wind. The simulation was successful – with rainfall in the desert increasing by a large enough amount so that vegetation could return to the Sahara.

“It is wonderful!” Dr. Kalnay was quoted as saying in an article by NPR. “We were so happy because it seems like a major solution for some of the problems that we have.”

The Sahara Desert solar farm in the simulation is gigantic – bigger than the entire continental United States. It’d be able to generate 400% of the energy the world currently requires. Would there be a way to install high-capacity transmission lines to transport this power across seas and land? It’s certainly a fantastic concept that seems straight out of a science fiction novel, but technology is increasing at such a pace that ideas like this are, whilst admittedly still in nascent stages, potentially viable. 

Take a look at our articles on printable solar panels/cells to see how, if room wasn’t an issue, how much cheaper large-scale solar could be with lower efficiency panels. 

More great information for solar cell technology. Just a thought experiment at this point but it’s exciting to see what the future could hold for renewable energy in the Sahara Desert!

Pilbara Solar Farm | Alinta Planning Off Grid Solar Farm

Posted on by — No Comments ↓

Alinta Energy have applied to the Western Australia Department of Water and Resources to clear 160 hectares at the proposed site of its Pilbara solar farm.

The planning application send through to the department is for permission to clear the 160 hectares of the site and also lays out a planning application for the Pilbara solar farm. 

“The clearing will be required so that Alinta Energy Transmission (Chichester) Pty Ltd (Alinta) can build, own and operate a solar field located adjacent to Fortescue Metals Group’s (FMG’s) Christmas Creek Substation in the Pilbara region of Western Australia (the Project),” the application says, according to RenewEconomy, who have quoted ‘solar industry insiders’ who estimate the size of the solar farm to be around 60MW (Alinta haven’t announced the size of the proposed farm yet).  

“The Project will supply FMG’s Christmas Creek mine site with power to support ongoing mining operations” the report continues.

It’s understood that the project will probably use single axis tracking and hopefully usurp the current energy for the Christmas Creek mine – an expensive and ecologically unfriendly 58MW diesel plant. This goes to show how important renewable energy in resources is – especially when you’re dealing with a site far from the grid. Some of these mines use an astronomical amount of power and having as much as possible of that power requirement coming from renewable energy is a fantastic step in the right direction for the resources industry in Australia. 

Last month Alinta made a development application for the 65km energy transmission line which would link the Christmas Creek mine with the Cloudbreak mine – so this gives us a bit of an idea as to what they are hoping to achieve in the future. Don’t be surprised if you hear more about this solar farm and a whopping great battery to go with it! Watch this space.
