Peer-To-Peer Renewable Energy Trading with Power Ledger

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…

Western Australia Solar Subsidies may be cut – Wyatt

Western Australia Solar Subsidies look like they’re in the firing line right now – with Energy Minister Ben Wyatt advising that he supports either completely scrapping or winding back rooftop solar panel subsidies.

Earlier this year the Australian Competition and Consumer Commission called to axe rooftop solar subsidies Australia-wide by 2021. Ben Wyatt said he has asked the Public Utilities Office to have an in depth look about the buyback scheme which could probably do with a bit of an overhaul, or at least a step in the right direction, technology wise.

“While the cost of solar PV systems has reduced significantly since the introduction of the Renewable Energy Target and is now considered economically viable in the absence of government subsidy, the implications of such a change need to be fully thought through, including the impact on the local solar industry,” Mr Wyatt said.

In WA, Synergy currently pays a feed-in tariff of 7.1c/kW to 240,000 households with solar – and over 70,000 customers entitled to the premium solar feed-in tariff which is 40c/kW (there’s no indication that the gov’t is looking at winding back the premium FIT). This is known as the Renewable Energy Buyback Scheme (REBS). Mr Wyatt said that Synergy are paying ‘over the odds’ for this power during hte middle of the day, when demand is low and output high. If you’d like to learn more about WA’s unique energy situation please have a look at this article.

We’re all for furthering the cause of solar, but is it worth taking a look at maybe moving some of the subsidies and tariffs towards energy storage rather than energy generation?

Ray Challen, who was the top energy adviser as the head of the Public Utilities Office up until the end of last year, said he thinks it’s time to consider the best way to continue improving our renewable generation:

“The reason for subsidising any form of behaviour is to produce some sort of greater social good, and it would be difficult to say at the moment that there is a greater social good from subsidising small-scale solar because people could do it anyway,” Mr Challen said. “Not only that but if you wanted to subsidise anything in the power sector then you would be probably subsidising batteries.”

So will we have a solar battery subsidy? It’s hard to say at this point, but many people are talking about making a change to the way we currently reward solar generators. Would a carefully managed solar battery rebate help? Watch this space…

Emu Downs Solar Farm Completed

The 20MW Emu Downs solar farm north of Perth, which is the largest solar farm in Western Australia and co-located with the 80MW Emu Downs wind farm and the under construction 130MW Badgingarra wind farm, has been completed. This will make the 230MW project the largest of its type, nationwide (for now!). It utilises single axis tracking technology from NextTracker and will help cover baseline power around lunchtime when wind patterns are weaker.

The Emu Downs wind + solar farm is the largest wind+solar project in Australia, beating the NSW Southern Tablelands’ Gullen Range Wind Farm and Gullen Solar Farm (165.5MW / 10MW respectively) It’s also bigger than the previous second biggest wind/solar  White Rock Wind Farm and the White Rock Solar Farm (175MW / 20MW), located New England Tablelands of NSW. 

APA received $5.5m funding from ARENA (Australian Renewable Energy Agency) back in 2017 for the 20 megawatt solar photovoltaic farm, also entering into a Power Purchase Agreement (PPA) to sell the electricity and STCs to energy provider Synergy until 2030. 

This will make the Emu Downs facility the first of 12 large-scale solar farms ARENA funded – with three in NSW (Griffith, Parkes, and Dubbo) almost complete, according to RenewEconomy. Emu Downs’ $5.5m was part of $92m ARENA gave the 12 solar farms which will eventually output a massive 492MW. 

APA CEO Mick McCormack made a statement in a media release to thank ARENA for helping them get the Emu Downs Solar Farm up and running:

“APA is grateful for ARENA’s support over a number of years to get this exciting project, APA’s first solar farm, constructed and delivering an enhanced energy solution from our combined wind and solar farm.” 

APA also bought the Darling Downs Solar Farm from Origin in the middle of last year, and it’s expected to finished construction this year.

Gov’t Owned Synergy Enters WA Market

Government-owned Synergy has entered the market in Western Australia for the sale and installation of solar and battery storage systems. This has caused an uproar – with many existing small businesses calling it ‘blatantly unfair competition’ and decrying the fact that a government-owned corporation with substantial competitive advantages will compete directly with small businesses. 

Synergy and the Potential Conflict of Interest

Synergy to enter domestic solar market in WA
Government-owned Synergy to enter the domestic solar market in WA

Synergy is a Government-owned corporation (website here), fully owned by the Government of Western Australia. Synergy, Verve Energy, Horizon Power and Western Power were created in 2006 as a result of the breakup of Western Power Corporation. On 1 January 2014 the retailer (Synergy) merged with the state-owned generation business (Verve Energy). They have a legislated monopoly to buy/sell all energy generated by PV solar systems on residential premises for the whole of Western Australia. According to Wikipedia, Synergy is Western Australia’s largest energy retailer and generator with more than one million industrial, commercial and residential customers, generating total annual revenue of more than $3.2 billion (14/15 financial year).

They recently entered the market for the sale and install of domestic solar/storage systems (which generally cost between $3,000 and $10,000,) competing directly with small businesses.  

Garry Itzstein and the National Electrical and Communications Association

A letter written by Garry Itzstein to the Small Business Minister, The Hon. Paul Papalia, is currently doing the rounds. Mr Itzstein is the Executive Director of the NECA (National Electrical and Communications Association) in Western Australi, which is a peak industry body representing the interests of electrical and communications contractors Australia-wide.

Mr Itzstein’s letter advises that the NECA WA “strongly urges the government to reconsider the previous government’s decision to allow Synergy to compete in the solar and battery storage installation market”, citing already increased competition and declining demand severely affecting existing small businesses. 

According to the letter, Synergy would be able to use their ‘monopoly status, financial strength and government subsidies’ to:

  1. 1 . advertise heavily to its existing customer base (which is the entire retail market of electricity consumers)
  2. leverage considerable purchasing power over equipment suppliers
  3. leverage considerable purchasing power over installers (in the end, these systems must be installed by a licenced electrical contractor)
  4. apply its vast marketing budget
  5. undertake pricing that borders on predatory

We’re inclined to agree – it seems unfair that Synergy are able to enter the domestic solar and storage market in WA and compete against existing businesses, given their huge and unfair advantages. What do you think? Sound off in the comments…
