Redflow – ZBM2 Microgrid in Tasmania for Hackett

Redflow CEO Simon Hackett has shifted his Tasmanian sheep and cattle farm to a new power source – a 100kW ground mounted solar microgrid using 27 Redflow ZBM2 batteries. Nice to see the bosses eating their own dog food. Let’s take a look at the project and what their future plans are for it.

Redflow – ZBM2 Microgrid in Tasmania for Hackett

Hackett, the owner of Redflow,  will use an initial deployment of 27 ZBM2 batteries, storing as much as 270 kilowatt-hours (kWh) of energy, interfaced to a large fault-tolerant cluster of 12 x Victron Quattro 48/15000 inverter/chargers.

“The project, with an overall budget of around $1 million, will include the building of a new site-wide microgrid. This will use new underground power interconnects to link seven distinct buildings across the whole property,” Hackett said in a statement. He went on to discuss the existing situation at the sheep and cattle farm he owns:

“We already have a Tesla Model S at the property and we plan to progressively replace our existing fleet of diesel farm ATVs, utes, and tractors with electric versions as soon they become available,” he said.

“We read with interest earlier this year that Toyota is committed to making electric HiLux 4WD vehicles and we would love to take delivery of the first of those to reach Australian shores.

Hackett explained that the Microgrid has myriad future plans and will be scalable:

“We can and will add more renewable energy generation using solar and/or wind if required in the future. Even after the full replacement of diesel vehicles with electric ones, we expect the property to be a net exporter of electrical energy to the Tasmanian grid,” he said.

Lastly, Hackett is very optimistic (mind you, he’d want to be) about the installation – we’re very interested to see some figures on how much it saves:

“I am convinced, based on my deep experience with Redflow, that ZBM2 batteries at the core of this energy system can deliver the hardworking energy storage and longevity to make this investment pay off over the long term,” he said in comments made last week.

Sun Cable – Australian Solar Farms Could Soon Power Singapore

Australian entrepreneur David Griffin of Sun Cable, who is a leader in the renewable energy industry, plans to use a solar farm located in the Northern Territory to power Singapore. His vision is still under development and once it is finished, will be the largest on a global level. Investors from all over the world are taking interest in this solar farm project.

Solar farm projects around Australia have been a huge success for the local communities. This project will be the first attempt to export renewable energy internationally. Mr. Griffin, who was General Manager at Infigen Energy, has been working on the development of wind and solar farms in South Africa and Australia for almost two decades.

The plan is for this solar farm to send electrical power to Darwin, and then under the sea through a cable to Singapore. He admits that the whole endeavour is quite complex and full of risks and for that reason, the design process will be expansive.

The Sun Cable farm will spread across 15k hectares and will be supported by a 10-GW power plant.The Government of the Northern Territory named it a ‘major project’ and construction is predicted to begin in 2023, after all environmental permissions and approvals are obtained.

Mr. Griffin’s goal is to provide electrification without harming the environment. Instead of clearing the Asian forests and causing climate catastrophe, he wants to produce large amounts of renewable energy using the abundance of space available in Australia. With its abundant sunshine, the Northern Territory strives to become the center of renewable energy.

Wealth for the Future

The Executive Manager of Innovation at the Commonwealth Scientific and Industrial Research Organisation, David Burt, considers Sun Cable one of the most important renewable energy projects, which will bring wealth for the country in the future.

Australia has a large mass of land, which means it has potential to produce wind or solar energy for export purposes. And considering the fact that the Asia Pacific countries are growing rapidly, Australia’s location is ideal for sending renewable power offshore. Sun Cable’s goal is to supply about 20% of the energy in Singapore, which represents an opportunity for the country to earn millions of dollars.

Australia already has huge optical-fibre cables undersea for the Internet. There is a risk, however, that these cables might get damaged which could disrupt the country’s ability to send energy.

Sun Cable Risk Assessment

Australia’s undersea cable is located in the Bass Strait connecting the Victorian and Tasmanian electricity grids. It feeds energy both ways, which allows the states to unload surplus electricity.

However, in South Australia, wind operators faced a serious problem when storms caused massive blackouts, upon which about 850k consumers were left without power back in 2016.

5B, a solar technology startup, will be supplying the solar panels pre-assembled in China for the Sun Cable project. 5B was founded six years ago by Eden Tehan and Chris McGrath and today it provides solar panels for twenty plants across Australia.

Each of 5B’s pre-fabricated ‘Maverick’ solar blocks is comprised of 80-200 panels. For Sun Cable, they need 80k Maverick blocks, which shows how large the project is.

The project is expected to create about a thousand jobs in the construction sector and another 300 in the operational sector.

According to David Griffin, now is the perfect time to enter the energy market in the region. At the moment, Singapore is highly dependent on gas from Indonesia and Malaysia. In general, electricity is very expensive in Asia. Mr. Griffin considers Sun Cable to be the first of many projects that will focus on exploiting opportunities in Asia.

Power Ledger Extend Solar Trading Trial

Western Australian based tech company Power Ledger have extended their solar trading trial – let’s take a look at what stage 2 of the company’s p2p renewable trading scheme will encompass.

Solar Trading and Power Ledger

Power Ledger’s blockchain technology has been used since November 2018 to track the transactions of rooftop solar energy traded between 18 households in Fremantle, Western Australia.

The Fremantle Smart Cities project was titled RENeW Nexus and its goal was to demonstrate peer-to-peer energy trading between residential houses. 

Project partners included Curtin University, government-owned retailer Synergy, Western Power, the government-owned network operator, and the City of Fremantle itself.

The trial works by utilising Western Power’s existing network with Synergy’s customers. The Power Ledger platform allows households to buy and sell excess rooftop solar energy in real-time, with residents able to view electricity usage in 30-minute intervals, rather than waiting for their quarterly bill.

Since the trial started in November 2018, Power Ledger has processed almost 50,000 transactions on its platform per month and tracked over 4 megawatt hours of peer-to-peer renewable energy trades. Safe to say it’s been a roaring success, so they’re off to start the second phase of their trial. 

Power Ledger are also working outside of Australia in varied capacity:

  • Silicon Valley Power in the City of Santa Clara alongside Clean Energy Blockchain Network
  • BCPG T77 Thailand
  • Kansai Electric Power Co. (Phase 1)
  • Vicinity Castle Plaza

Saving With Solar Interview with Power Ledger

We had a chat to Power Ledger about the exciting second phase of their renewable energy trading scheme

With ~50k transactions per month currently, what’s the target for 2020?
Power Ledger intends to double the number of participants in the second phase of the trial.

How many trial partners will be involved in stage 2?
In the second phase of the trial we continued to partner with Synergy, Western Power, Curtin University and EnergyOS 
 
Any info on the ‘additional pricing models’ in stage 2? 
The pricing model for stage 2 is similar to stage 1, with some minor tweaks. The partners will be organising workshops and surveying participant to learn more about pricing models. 
 
How much of the trading is automated so the prosumers don’t have to do much?
All the trading is automated. in this deployment however, participants have the option to set their preferred buy and sell prices for peer to peer energy. They can be as active as optimising their prices and trading on a half hourly basis. Alternatively they could go in the platform and set and forget their prices they are happy with.

VPP 2.0 (Virtual Power Plants 2.0)

According to a roadmap for Power Ledger released on Medium last year, the goal is to enact VPP 2.00 – which will allow a lot of options for households who want to trade solar. It also factors in ideas for a two-way electricity grid and options for households to assist the grid – be that through capacity, frequency control, or voltage support.  

We see VPP 2.0, or Virtual Power Plants 2.0, as a natural extension of our peer-to-peer functionality, tying all our other products together. xGrid will evolve into an optimized model of a virtual power plant, to create a conduit for the transaction of value between the owners of distributed energy resources and multiple counterparties.

Self-executing smart contracts will integrate with physical switches in the network, creating an autonomous power market with secure value transfer between consumers, energy markets and networks. For example, a household with solar may normally be trading energy in a P2P market, until they are offered a higher rate by the network to provide capacity, frequency control, or voltage support.

Coles Solar Power – Supermarket signs commercial solar PPA.

Coles solar power – the giant supermarket company has signed a power purchasing agreement (PPA) with global renewable power generation company Metka EGN. Another huge step for commercial solar and retail solar. Let’s read more about it.

Coles Solar Power

The goal is to buy more than 70% of the energy generated by three solar power plants. The plants will be bnuilt and operated by Metka EGN in Wagga Wagga, Corowa, and Junee in New South Wales – this represents 10% of the company’s entire national electricity usage! Metka EGN are a London based EPC contractor working as a subsidiary of Greek company Mytilineos Holdings S.A. According to PV Magazine, construction of 169MW will commence by EOY and project development is at an ‘advanced stage’. 

Coles Group CEO Steven Cain discussed the move and Coles’ goal to be the most sustainable supermarket in Australia:

“Coles has been a cornerstone of Australian retail for more than 100 years, and ensuring the sustainability of our business is essential to success in our second century,” he said.

“We are thrilled that with this agreement, Coles can make a significant contribution to the growth of renewable energy supply in Australia, as well as to the communities we serve.” Mr. Cain continued.

Thinus Keeve, the Coles Chief Property and Export Officer, had some comments about the Coles solar power scheme – noting that it’s the first Australian retailer to commit to buying renewable energy through a PPA.

Metka/Coles’ solar plants will supply over 220 gigawatt hours of electricity to the national grid. This will result in the displacement of over 180,000 tonnes of greenhouse gas emissions every year. According to the media release this is also the equivalent of the annual emissions of 83,000 cars.

What will Woolworths do to compete with this? Watch this space…

Greenpeace Australia Pacific Senior Campaigner, Lindsay Soutar spoke on the issue:

“Some of the world’s biggest companies, including supermarket chains Walmart and Tesco, have already made the commitment to 100 per cent renewable.

“We look forward to seeing Woolworths make similar commitments,” she said.
