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.

Green Power Solar Blockchain ICO

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.

The Pre-ICO for Accredited Investors starts in 98 days as of 05.06.2018, so now’s a great time to start researching the company if it looks interesting to you.
