Power Ledger Extend Solar Trading Trial

Posted on by — No Comments ↓

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.

Solar Waste – What’s the state of solar panel recycling?

Posted on by — No Comments ↓

Solar waste is a currently unavoidable byproduct of Australia’s obsession with solar power. But what do we do with these panels when they reach end of life? Let’s take a look at solar panel recycling and what the current climate is, helped by a recent ABC Radio show about the topic.

Solar Waste and solar panel recycling – a primer.

We wrote about recycling solar panels back in January, but a new interview with Reclaim PV (who we talk about in the other article too) has some more information about this critical issue. 

A radio program by the ABC had some very interesting thoughts on the topic – you can listen to it here. 

The panel included:

  • Jeremy Hunt, solar panel installer
  • Professor Rodney Stewart, Griffith University
  • Clive Fleming, solar panel recycler, Reclaim PV
  • Andrew Gilhooly, Sunpower

With two million houses in Australia now enjoying the fruits of renewable energy and installing solar on their rooftop, their lifespan of 10-15-20 years is now starting to slowly fizzle out, especially for the early adopters. However there’s a huge issue to do with disposing of the solar PV waste in an environmentally friendly fashion.

Professor Rodney Stewart from Griffith University estimates that by 2050, we’ll have 1,500 kilotons of solar waste which will be sent to landfill unless we can figure out a more intelligent way to dispose of something supposed to help the environment.

The only company in Australia to recycle panels is Reclaim PV in Adelaide, who take in 50,000 per year, but only panels manufactured without toxic chemicals. They then, according to owner Clive Fleming,

“…get the cells, completely separate that as well for the silver contacts, the aluminium and then the silicone to provide those back out to industry.”

According to the ABC program host Emilia Terzon, the Federal Government says it’s committed $167 million to an Australian recycling investment plan and state and federal environment ministers are expected to discuss how to tackle solar waste when they meet later this year. The Government is looking to set rules around how the industry deals with dead solar panels – adding them to the Product Stewardship Act, which mandates how electronic waste is dealt with.

Australian Council of Recycling chief executive Peter Schmigel also had a quote in the Sydney Morning Herald earlier this year 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.

Watch this space. There will be plenty more on this topic as panels continue to reach EOL (end of life) and the policymakers are forced into action.

The scheme, which is using $50m redirected from a cancelled virtual power plant program, is still missing a lot of information. According to the official website it aims to ‘unlock up to $3.2 billion in clean energy investment, adding up to 3,000 megawatt hours of storage into the NSW energy system when complete’. 

“I want to deliver a program that provides robust consumer protections in terms of safety, system performance and value for money,” NSW Minister for Energy, Matt Kean, said in comments reproduced on the NSW Government’s website.

According to Solar Quotes and statistics provided by the Australian PV Institute, New South Wales’ solar penetration (at ~19%) is quite far behind Queensland (34.1%), South Australia (33.5%), and Western Australia (27.6%). 

According to figures from the Government website, “a household with a $500 quarterly electricity bill could save up to $285 a year on their bills while repaying the no-interest loan. Savings could increase to over $2000 a year once the loan is repaid.”

For further information about battery systems please visit Energy Saver NSW.

If you’re like to register your interest in the Empowering Homes program and also receive updates as they become available, please click here and fill in the form at the bottom of the website. According to the official site the first battery/solar-battery systems will be available for install in summer 19/20.

Daintree microgrid project | Hydrogen

Posted on by — No Comments ↓

The Daintree microgrid project has been funded almost $1m by the federal government. It’s set to become Australia’s first solar to hydrogen microgrid and will replace reliance on an expensive and polluting diesel system. Let’s learn more about it!

The grant amount is $990,150 which will go to the Daintree Renewable Energy Pty Ltd company, as per an article in Energy Magazine, which also noted that the fund will complement the AEMO’s review of microgrids and the regulatory bodies which will govern them, created by the government in August of last year.

Russell O’Doherty, president of Daintree Renewable Energy, was quoted in an interview with Newsport:

“This power will be used to help power the hydrogen cell; the hydrogen gas produced will be collected and stored and used to fuel large scale generators. The only by product of this system is hot water,” he said.

“This is absolutely fantastic news for the environmentally-conscious Daintree community,” Federal Leichhardt MP Warren Entsch also weighed in:

“Far North Queenslanders, especially those living in the Daintree, are extremely passionate about their natural environment and this announcement is a big win for the entire region.”

“The proposed microgrid will store energy generated by new and existing solar panels by converting it to hydrogen, generating reliable power and reducing the World Heritage Area’s reliance on diesel fuel to generate power, with consumption currently estimated at around 4 million litres of diesel per annum,” Federal Energy Minister Angus Taylor said.

However it’s not all peachy in the Daintree – the Douglas Shire Sustainability Group is clashing with Daintree Renewable Energy with regards to reticulated power north of Daintree. According to PV Magazine Australia, the DSSG is concerned the renewable project could result in long term damage to the world heritage environment and to tourism. You can learn more about that by clicking here. Watch this space to see what happens there, but surely moving from diesel to solar is a no brainer!

Redeployable solar trial at shopping centres

Posted on by — No Comments ↓

Redeployable solar is a very interesting topic as the issue of solar panel recycling comes to the fore. This week ARENA have announced funding for redeployable commercial solar via Australian startup Solpod. 

Redeployable solar

Redeployable solar – on Friday the Australian Renewable Energy Agency (ARENA) announced funding for an Australian start up (Solpod Pty Ltd (Solpod)) to trial the installation of movable solar panels on commercial and government building rooftops. 

According to a post on the ARENA website, the startup has undertaken trials with ARENA, ERM Power, GPT and Property NSW.

Arena CEO Darren Miller, who took over from previous head Ivor Frischknecht last year, was quoted discussing the redeployable solar and their partnership with Solpod:

“Solpod’s new way of installing solar will pave the way for businesses who were previously locked out of rooftop solar to take up renewable energy solutions and options under shorter term power purchase agreements.

“This Australian start up will help to accelerate solar PV innovation and allows for renewable energy alternatives in niche markets, providing a cost-competitive alternative to standard methods of fixed mounting for delivering rooftop grid connected solar PV,” Mr Miller said.

There were also some comments from founder and CEO of Solpod James Larratt, who discussed the new ‘game-changing’ tech:

“Despite rooftop solar being cheaper and more sustainable than the grid, many businesses have made the rational decision to not adopt solar because of other factors such as length of commitment, disruption on site and damage to buildings. Solpod is the game-changer that removes these barriers and enables businesses to capture the savings in energy costs.”

“Solpod’s solution can adapt to meet individual business needs. For businesses that rent their premises, Solpod can offer short-term contracts to match lease terms. For landlords, Solpod allows flexibility for changing site use and will not damage the roof,” he said.

You can learn more about Solpod’s relocatable commercial solar via their website.
