The Sydney Markets solar installation at their Flemington location has been turned on – the $8.9m solar system is Australia’s largest private solar rooftop installation and is expected to save the markets millions of dollars in electricity bills.

According to Fairfax Media, the panels were installed by Autonomous Energy over a five month period and the 8,600 panels are able to generate more than 3MW – which is about 11% of Sydney Markets’ annual power usage. The markets are the largest food distribution centre in the Southern Hemisphere and turnover around $3b each year, so to see a company this big working on their sustainability is great.

Brad Latham, the chief executive of Sydney Markets, said after stringent modelling, watching the market and seeing what other private solar investment was doing in Australia, they decided it was the right choice:

We’ve been examining solar panels for around five years, the financial models really stack up now,” Mr Latham told Fairfax Media.

“And with current electricity prices and the efficiency of solar panels it makes sense.”

Latham discussed how the Flemington-based Sydney markets already recycle about 70% of their on-site waste and how the renewable energy fits into their wider plan to make the markets as sustainable as possible:

“It’s part of our strategic plan to be leaders in sustainability. This solar power system will enable us to generate sustainable energy, as well as drastically reduce our carbon footprint,” Mr Latham said.

“In order to extract the same amount of carbon dioxide from the atmosphere, 676 hectares of trees would be need to be planted each year.”

Chairman of the Sydney Markets, John Pearson, said this was just the beginning and they have big plants to expand the private solar system:

“Sydney Markets has additional roof capacity to more than triple the generation of this solar system,” Mr Pearson said.

“We may continue to build upon and expand this system to meet our future energy needs.”

Pearson discussed how they think energy storage technology hasn’t quite reached the point where they’re ready to shell out for it, though:

“We don’t think batteries are quite there yet, they are still a little ways off but it depends on the financial models,” Mr Latham said.

Another step forward for Australian businesses installing solar systems!

Tesla Battery in SA Earns $1m in a few days.

Posted on January 25, 2018 by Mike — No Comments ↓

The Tesla Battery in SA has earned an estimated $1m in the last few days due to warm temperatures and a very volatile electricity market. Since being announced in July of last year and completed in November, the battery has already withstood a test last December when the Loy Yang Power Station (sector A3) tripped and went offline – the battery was able to send 100MW to the grid in 140ms, despite being almost 1000km away. It’s now proving its value again during a hot Australian summer where it was paid up to $1000/MWh to charge itself last week, according to Electrek and RenewEconomy.

The 100MW/129MWh Tesla Powerpack system installed in South Australia (which is known to the grid as the Hornsdale Power Reserve) was built by Tesla and is operated by Neoen -who have access to about 30MW/90MWh of the battery’s capacity to trade on the wholesale market. The South Australian government have access to the remaining electricity to help stabilise the grid.

As we saw with its 140ms response time, the Powerpack is able to offer energy to the wholesale market a lot faster than its rivals – allowing Neoen to profit from the large swings in energy prices in Australia (which become even more intense when we have a heatwave or there’s an outage at any of our major plants).

Elektrek are reporting that during certain peak periods, Neoen were able to sell energy at up to $14,000 per MWh, according to forecasts from RenewEconomy on the 23rd.

A couple of weeks ago Tesla was chosen to build another Powerpack battery in Bulgana, and the company fronted by the charismatic Elon Musk is also working in conjunction with Neoen to bid for even larger battery projects – so hopefully the good results the battery in SA has been delivering will bode well for the future.

Redflow in Thailand – Produce First Battery Stacks

Posted on January 23, 2018 by Mike — No Comments ↓

Redflow in Thailand – we reported last year on their decision to move manufacturing of the Redflow zinc-bromine flow batteries to Thailand. Today they have emailed out a press release advising that they’ve successfully produced the first battery electrode stacks from the new factory southeast of Bangkok at the Hemaraj Chonburi Industrial Estate.

Redflow in Thailand

Redflow announced in December last year that they had successfully started manufacturing core components for the zinc-bromine flow batteries at its new production facility – with the successful production of electrode inserts made of HDPE (High-Density Polyethylene) plastic at their Thai factory.

Today’s press release noted that they’ve now successfully produced battery electrode stacks – a key component of the ZBM2 zinc-bromine flow battery. The stacks involve using electrodes that charge and discharge the battery by “plating” and “deplating” zinc on a membrane. This process means the membrane is able to sustain 10 kilowatt-hours of energy storage capacity throughout the battery’s operating life, which is estimated at 10 years of 36,500 kWh of delivered energy (whichever comes first). Keep in mind that battery performance and lifetime won’t be sensitive to cycle depth as there are no limitations due to the nature of zinc-bromine flow batteries. They’ll deliver 100% depth of discharge every day for their warranted time and this doesn’t cause any damage to the battery.

According to the Redflow Limited Managing Director and CEO Richard Aird, the process has been smooth sailing so far:

“The manufacturing team is very happy with the consistent quality and acceptable yield metrics of the stack line,” he said in the press release.

As per Redflow’s manufacturing timeline, they are well on track to be able to produce complete batteries by June of this year.

It’s been a brave move for Simon Hackett’s Redflow, who have had a challenging 2017 and made some tough operating decisions for the new year. We’ll keep you updated as to how production goes for their batteries.

Adani’s Whyalla Solar Farm greenlit

Posted on November 8, 2017 by Mike — No Comments ↓

India based energy company Adani have received development approval for a $200 million, 140MW Whyalla solar farm. The farm will consist of PV solar modules and operate on a single axis tracking system.

The solar plant will be located 10km north of Whyalla’s centre, on the Port Lincoln Highway. It will originally generate 100MW and the potential capacity of the solar plant will be up to 140MW. According to AdelaideNow, grid connection will be via the 132kv network between the Whyalla Centra and Cultana substations.

Although the original development application didn’t include any information about battery storage, this is an option that Adani is also investigating.

No PPA (Power Purchasing Agreement) has been signed yet, but as soon as that is sorted out we will see a starting date for construction of the farm – which is expected to be some time in 2018. The plant should be generating renewable energy by 2019. The construction phase of this solar farm is expected to create 350 jobs and could be “just the tip of the iceberg” for Whyalla, Giles MP Eddie Hughes told news.com.au last year.

“Since 1998 Whyalla has wanted to become the solar capital,” said Mr Hughes. “It’s the realisation of the dream to have a major proponent come to us.”

Other Whyalla Solar Projects

News of Adani’s solar farm comes off the back of Zen Energy approving a $700m solar, battery and pumped-hydro storage project to power Zen Energy owner Sanjeev Gupta’s Liberty OneSteel works in Whyalla. The project is expected to provide 1 gigawatt (1000MW) and also 100MW/100MWh battery storage. Hopefully, this will also provide some help to the real estate market in Whyalla, which has dropped by 21% in 2017 so far.

Adani also has another $100m solar farm in Moranbah awaiting DA from the Isaac Regional Council.

Redflow News: to move manufacturing to Thailand

Posted on September 1, 2017 by Mike — No Comments ↓

A lot of Redflow news recently – the Australian solar battery manufacturer has had a fairly tumultuous 2017, with the temporarily halt in delivery of their zCell batteries to fix some operational issues, to a steadily sinking share price. The last couple of months had had more positive news, with an $800,000 sale of its ZBM2 batteries to New Zealand company Hitech Solutions and the establishment of a company in Thailand to manage the manufacturing process of its zinc-bromide flow batteries in South East Asia.

Redflow News: Equity, Thailand, Change in Direction..

Redflow News - ZBM2 Solar Battery — Redflow News – ZBM2 Solar Battery

Redflow Limited made a statement to the ASX on August 17 where they noted that the final North American production batch of ZBM2 batteries is now in transit to Australia. They have a new manufacturing partner, Malaysian based MPTS, who have been a long term supplier of components for the Redflow battery. They have moved their manufacturing base from Flex in Mexico to Thailand, and have cut staff in Europe and the US in order to streamline operating costs.

They also completed an equity raising round via a share placement of $10.5 million in two portions to investors and another $4 million in shares to Hackett CP Nominees Pty Ltd (i.e. Redflow CEO Simon Hackett).

Hackett was positive about the future of the company, noting that “In May Redflow recorded its largest sale to date, to an energy systems integrator working in the telecommunications and network power sector.”

Meanwhile, Redflow Chief Operating Officer Richard Aird discussed the impact of moving manufacturing locations and hinted towards their plans for the future, posting on the Redflow website that “The activities Redflow is undertaking to transition manufacturing and to implement key product cost-down projects are critical to the future success of the company,”.

This comes off the back of a statement by Redflow that they were less bullish about the future of their ZBM2 zinc-bromide flow batteries in the residential sector in Australia, given the rapid sink in cost of mass produced lithium ion batteries and being unable to match these prices. A statement from the company advised that a strategic review has necessitated a change in focus:

“The review anticipates that this may not translate into strong sustained sales growth in the mid and late majority residential market, due to the price-sensitivity of competitive, highly commoditised markets, which tend to prioritise a low purchase price over technical advantages, such as those offered by Zinc-Bromine flow batteries.”

Quite a big quarter for Redflow news and we’ll be interested to see how its move into large arrays of battery storage goes – the company has identified that they will focus on more mature markets – industrial, commercial, off-grid, telecommunications companies where they will look to replace existing lead acid battery with their zinc-bromide offering.

Will the $800,000 sale to Hitech Solutions be a flash in the pan or a harbinger of things to come? It’s great to see how they have been flexible in terms of moving around their operational focus – hopefully this new focus will prove to be more fruitful than their foray into the residential market.
