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.

WePower partner with Marubeni Corporation

Posted on by — No Comments ↓

Renewable energy procurement and start-up platform WePower have secured a strategic equity investment via Japanese investment/trading corporation Marubeni Corporation. A press release was published this morning. Let’s take a look and see what this could mean for businesses looking to purchase renewable energy on a scale they’re comfortable with. 

WePower partner with Marubeni Corporation

You might remember WePower’s ICO at the start of last year – the blockchain-based green energy trading platform has enjoyed a massive financial coup by partnering with Marubeni Corporation. This will support rapid expansion of their ‘disruptive green energy procurement platforms’. This is really exciting news for a company we have been watching for a couple of years. We’re looking forward to seeing what their attitude towards PPAs for smaller (‘almost any’) companies will fare – so you don’t have to go all out on commercial solar (such as the XXXX brewery at Milton’s solar installation) and can just buy what you need at a smaller level.

WePower sees Australia as one of the fastest growing markets globally for power purchase agreements (PPA) and this investment will help bring green energy to corporate and industrial consumers from around Australia.

According to a press release from today, WePower Standardised Power Purchase Agreements (PPA) streamline risk management and introduce previously non-existent liquidity for the energy purchased via direct energy contracts.

Nikolaj Martyniuk, WePower’s Co-founder and CEO, says the investment was secured because of deep synergies with Marubeni Corporation’s Power Business Division.

 “We are delighted to work in partnership with Marubeni Corporation to develop and introduce new commercial energy services, as well as scale our solutions globally to markets including Australia.”

“Two-thirds of the energy produced worldwide is consumed by commercial and industrial clients. So, any meaningful change towards a fully sustainable future is not possible without enabling more corporate and industrial consumers to participate in the green energy revolution.

 “To date, only the largest global corporations have been able to access renewable power sources by directly purchasing from a producer. The complexity of this process has created a barrier for smaller companies looking to integrate renewables into their energy mix and contribute to the growth of green energy development,” Nikolaj continues in the press release

Yoshiaki Yokota, Chief Operating Officer, Power Business Division, Marubeni Corporation discussed the deal:

 “We did it by disrupting the traditional energy supplier business model with a deep focus on big data and a radically different approach to energy sourcing, management and trading. We believe WePower is in a unique position to disrupt the traditional corporate energy procurement markets by allowing almost any company to buy energy directly from renewable producers.”

Peer-To-Peer Renewable Energy Trading with Power Ledger

Posted on by — No Comments ↓

Australian blockchain solar startup Power Ledger has partnered with Yolk Property Group to apply its renewable energy trading between residents in their White Gum Valley development. This marks the first time an apartment development utilising blockchain technology has been offered for sale to the public in Australia. 

Peer-To-Peer Renewable Energy Trading

The White Gum Valley project is an ARENA funded sustainable living innovation project. Inside White Gum, Yolk Property Group are building an apartment development named ‘Evermore’ which will have solar PV panels, battery storage, and, of course, the Power Ledger blockchain technology we have written about quite frequently on this site.

According to The West, the project is being overlooked by a team at Curtin University headed up by Professor Peter Newman. They are collecting and analysing the data to help inform Western Power and national authorities on energy infrastructure – viewing this as a learning experience.

“The world is watching – I think that now there are people all round the world saying they’re doing it in Perth why can’t we?” Professor Newman said.

Yolk Property Group have advised that expected cost savings for residents will be around 30 to 40 per cent. Certainly nothing to be sneezed at!

Under the Power Ledger method, buying and selling of power happens automatically and is all stored in the blockchain – so it’s really easy to manage and is very hands-off.

“If you’ve got excess solar now, your solar panels are producing energy while you’re away at work or you’re away on holidays – that energy gets spilled into the grid and you sell it to Synergy your retailer,” Power Ledger’s David Martin said.

“Now, under the model we have here, instead of selling your energy to Synergy you can sell it to your next door neighbour at a better price.”

If we can manage to get a solar battery rebate in Australia, will that help methods like Power Ledger? Watch this space…

Natural Solar – Blockchain Powered Community Solar

Posted on by — No Comments ↓

Australian company Natural Solar have advised that they will be using the power of blockchain technology its its latest community solar offering – a new housing development just outside of Sydney which will see 12 homes share power with each other.

Nine are reporting that each home will have a 5kWp solar system and an 8kwh sonnenBatterie 8 installed. Homeowners will be guaranteed up to 20 years of $0 power bills, but they will have a $30 / month bill to sonnenFlat for the program. Power will be shared between the 12 houses and any energy movement will be recorded on the blockchain to record and track the efficacy of of the project. Is 12 houses enough? What happens when it’s 4pm on a Tuesday and 8 houses have air conditioning on? 

If this is a bit complicated to understand, Chris Williams, CEO and Founder of Natural Solar,  explains the concept as a ‘super battery’:

“Utilising Blockchain technology, we are able to join all batteries together to create one larger ‘super-battery’ that can power all homes in one development.

“An advantage of this is for the first time ever in Australia, residents will now be able to borrow power from their neighbours who have excess stored in their own battery, creating a complete sharing economy amongst houses.”

What happens if the energy runs out?

This question was put to Williams who said that, although this model means the developer won’t have to pay for expensive grid upgrades, it’ll still have access at all times: 

“In the event houses need additional power and they can’t borrow extra from their neighbours, they are able to automatically draw this from the grid. If the home is signed up to the sonnenFlat energy plan, this will be free of charge for most houses, provided this fits within their annual electricity consumption.”

The project is set to launch by September – so watch this space and we’ll keep you updated on the progress of Natural Solar’s great project.

Green Power Solar Blockchain ICO

Posted on by — No Comments ↓

Green Power Exchange (GPX) is a startup which is hoping to create a global platform for peer-to-peer renewable energy trading – with the goal of making renewable energy trading simple and convenient – resulting in a lower price because the energy is being sent directly from producer to consumer, cutting out the usual middlemen.

Green Power Exchange 

GPX’s solution is to eliminate intermediaries and launch a simple, easy to use peer-to-peer platform to buy and sell renewable energy. The local distributor will still need to be paid for line rental, but apart from that this eschews the traditional energy supply chain which consists of 1) Generation, 2) Transmission, 3) Distribution and 4) Retail. Obviously all steps in the supply chain result in a higher cost per kilowatt so it’s great to see some options where someone can buy directly from the producer. 

Crypto Reporting have done some research about Green Power Exchange, how it works, and how much you could save – offering up the example of a producer usually receiving $0.06 USD / kWh from a wholesaler or retailer while the end user is still paying around $0.20 USD / kWh. This is over 300% more than the producer receives – and as the energy goes from transmission to distribution to retail everybody adds on a clip. Not very efficient, and since the producer and end buyer are artificially separated like this, it’s difficult for them to meet and reach an agreement on a price. Enter GPX!

With direct trading, a cost per kWh could be $.1 USD which benefits both parties (the customer would still have to pay line rental to the local distributor which would be around $0.02). In this case the producer receives $.1 USD instead of $0.06 and the customer pays $0.12 instead of $0.20 per kWh. 

For GPX to work, you’ll need a smart meter which will be checked and then energy distributed through smart purchase power agreements posted on the blockchain. Given that PPAs will have to differ depending on the jurisdiction, Green Power have set up standard templates for everywhere the platform operates. There’s also the option to upload your own PPA which will then be vetted by the team to ensure it conforms with their standards.
