The 24 month trial period means that customers participating will be able to ‘virtually’ store excess power they generate during the day (it’ll be fed into the utility-scale 105kW Tesla PowerPack Battery). They can then use 8kWhs of the PowerBank’s battery storage without needing to install their own power bank. According to the press release (and it’s true!), “8kWhs is enough to power the average suburban home for over one hour during peak time.”

Energy Minister Ben Wyatt discussed the Tesla PowerBank trial in a series of interesting quotes which explain how helpful this trial could be to Mandurah residents:

“PowerBank is an ‘in front of the meter’ storage trial which allows invited local customers to store excess electricity from already installed solar PV systems to then use it during peak times.

“This is another Australian milestone for the application of utility-scale batteries for the benefit for customers, drawing on the groundbreaking work by Synergy in its Alkimos Beach energy storage trial.

“For the first time in Australia, a utility-scale battery will be integrated into an established suburb’s network, like Meadow Springs, that has a high level of existing solar PV uptake.

“At the cost of one dollar a day, customers will have access to 8kWh of battery storage to use any time after 3pm each day.

“This trial shows that the WA Government is serious about working with renewables, delivering for taxpayers and planning for our energy future.”

Kiamal solar project launched, may add 194MW more.

The official launch of the Kiamal solar project was held in Victoria on Wednesday. The 265MW (DC) solar plant has plans to double its output by adding another 194MW in the future at some point.

The Kiamal solar project is owned and being run by Total Eren (formerly two separate companies), a renewable energy company based in France whose $300m investment in the project has raised the ire of the Australian Energy Market Operator, who have implemented tough new conditioned for those wanting to install wind and solar in Victoria’s ‘full’ grid (click here to read a great article from the AFR about it). They commented that Total Eren had ‘misjudged’ the system strength requirements and said there could be an issue with adding a farm this size to the noth-west Victorian grid.

Luckily the team at Total Eren (or Total-Eren, depending on how French you are) have agreed to add an expensive ‘synchronous condenser’ to help stabilise the grid. AFR report that the cost is estimated to be in the ‘tens of millions of dollars’ so this is certainly quite the olive branch. 

An official statement from the company noted that the company had acquiesced to AEMO’s requests “…in order to facilitate a timely connection … substantially strengthening the grid in the region and making it possible to connect even more renewables in north-west Victoria”.

The team are now looking into adding 380MWh of energy storage and 194MWh of solar in a second or third stage, as per executive vice-president Fabienne Demol. 

NSW Energy Minister Don Harwin spoke at the Financial Review National Energy Summit and explained the situation a little further:

“There are plenty of people who want to advance new renewable energy generation options here in NSW, but transmission is a huge constraint and that is why we are ahead of the game, out there with our own strategy, carefully reviewing all the work AEMO has done in the ISP to make sure it works for NSW consumers ,but whatever we do we will be doing it in a way to make sure it doesn’t lead to upward pressure on prices because that is our critical focus and that is the assurance that we will give.”

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 Battery Rebates in Victoria | Solar Homes Program

Solar battery rebates in Victoria will be rolled out as part of the Andrews’ government’s $1.34b Solar Homes program. The program also includes half price solar panels for 650,000 households and a $1,000 discount on solar hot water installation for 60,000 households.

Victorian home owners who fit the criteria (it’s means tested) will get a 50% rebate to install battery storage. The rebate will be capped at $4838 in the first year and will slowly decrease to $3714 by 2026, factoring in the inevitability that prices will decrease and energy storage technology will improve. The Age are reporting that this policy will cost an estimated $40m, with around 10,000 Victorian households expected to take advantage of the fantastic subsidy offer. 

According to the SBS, it’s part of Labor’s wider plan to increase renewable energy use and decrease the cost of living – with the plan being to work with energy distributors and invest $10m to help ‘renewable-proof’ the state grid over the next ten years. 

“This is a game changer for Victorian families fed up with big corporations that have been price gouging and ripping consumers off,” Premier Daniel Andrews said.

“Only Labor will put solar panels, solar hot water or solar batteries on 720,000 homes – saving Victorians thousands of dollars on their electricity bills with renewable energy.”

Solar Homes Victoria Subsidy Breakdown

We’ve previously written about Labor’s half price solar for Victorians scheme- looks like there are some great plans coming to fruition for the state. 

Solar Panels – $1.2b for 50% of solar system installation costs for 650,000 homes.

Solar Hot Water – $60m for $1000 subsiddies to install solar hot water.

Solar Batteries – $40m for 50% of solar battery installation costs for ~10,000 homes.

It’ll be very interesting to see how these solar battery rebates work in Victoria and if the other states (especially the ones with a high solar panel update) follow suit. Watch this space – we’ll keep you updated!

Solar and Wind Farms in the Sahara Desert

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. 

Solar and Wind Farms in the Sahara Desert

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!

Darling Downs Solar Update | Jobs, Farms & More

Darling Downs solar is helping the area by providing jobs to locals and kickstarting the economy – with one council already approving $6b worth of wind and solar projects. There’s now a ‘buzz’ around the Darling Downs and renewable energy – let’s take a look at what they have in the pipeline!

“We’ve got $1.2 billion of that under construction now, and that’s the exciting thing, this isn’t just about approvals, this is about action to deliver renewable energies to this region,” Western Downs Regional Council mayor Paul McVeigh said in comments to the ABC

“And we know there are another three [solar farms] in the pipeline.”

In Warwick, the 154,000 megawatt-hour generating UQ / Warwick Solar Farm is to be installed on ‘good agricultural land’ has had to wage a battle against NIMBY detractors. Mayor Tracy Dobie defended her decision (she had the deciding vote to allow the farm DA):

“This region is about growth and development and we can sit here and go poor slowly or we can progress our region and the more development we can get in our region the more jobs,” Ms Dobie said.

“The more progress we can make, the better off we are.”

Mayor Dobie continued to discuss the project and what she sees the future of renewable energy in the Darling Downs as looking like:

“This is a turning point in our region to show we are moving forward, that we are looking to the future, and there is nothing more evident than that than renewable energy.

“There’s a buzz about the Darling Downs, this is a great place to be and great time to be here.”

Toowoomba Solar

There’s been an amazing amount of renewable energy movement in Toowoomba – with the billion dollar project at Bulli Creek approved by the Tooowoomba Council. This will be built by Solar Choice over a 10 year staggered period. 

Toowoomba mayor Paul Antonio spoke about the concerns some residents may have and why he’s happy to continue approving solar farms:

“I guess we have to be a bit cautious of the type of land we put it on, but in saying that, the land is restorable, its not going to be destroyed in any mining effort or anything like that, and in 20, 30, 40 years’ time that land will be back to full production.”

Have a look at the short video below from ABC Landline which was part of an article about using ‘good farmland’ for solar farms.

Hornsdale Power Reserve saves $8.9m in 6months

Hornsdale Power Reserve – also known as the Tesla South Australia battery, the 129MWh solar/energy storage battery has saved the state $8.9m in six months, according to Renew Economy and their analysis of spot market pricing in 2018.

Hornsdale Power Reserve

The cost of the Hornsdale Power Reserve hasn’t been made public, but at ~$800 per installed kWh the cost comes out to around $100m (with around $50m paid by the government), which fits the whispers we’re hearing around the traps.

The partnership between Tesla and South Australia was inked in July last year as Elon Musk and then-Premier Jay Weatherill decided on Neoen’s Hornsdale wind farm as an installation spot. The Tesla Battery was then completed on November 24, ahead of its December 1 operation deadline (Musk made a bet with Weatherill/South Australia that Tesla would install the Powerpack batteries by December 1 or the project would be free).

According to an analysis undertaken by RenewEconomy and investigated further by Clean Technica, The battery saved $5.7m in its second quarter of operation. It bought power at an average price of $79/MWh and sells it at $191/MWh (a figure somewhat distorted by a very power-hungry January – with that month removed the price goes down to $141/MWh). The estimated savings for the full 2018 are expected to be around $18m. 

It’s important to note that the battery is still trading 30MW (of its total 100MW) of capacity so there is space to expand operations should the government be so inclined. 

If you’d like to read a more detailed account of how much money the Hornsdale Power Reserve has saved South Australia in 2018 click here to read Stephen Parker and Bruce Mountain of the Victoria Energy Policy Centre investigate the economics of energy generation/storage.
