The disruption and the opportunities being offered by solar PV and battery storage are likely to be accelerated massively by the introduction of new software such as the “blockchain” system that has already taken root in financial systems, writes Giles Parkinson of the leading Australian energy website Reneweconomy.

As more than 200,000 solar households in Australia get ready to lose their premium feed-in-tariffs at the end of the year, most are wondering “what’s next” for their electricity arrangements. But the same question is being posed by big utilities, who are facing a scale and pace of disruption that could never have been anticipated.

Much has been written – on this website and elsewhere – about the impact of the (still) plunging cost of solar and the arrival of battery storage.

But the disruption offered by these technologies will be accelerated strongly by the introduction of new software, such as blockchain technology, which was first used in bitcoin transactions.

“There is no question about where you got your kilowatt hour, where it came from and how it was produced”

This technology holds the promise of lower bills for consumers, more localised and community-based energy, greater resilience for the entire electricity system, and huge implications for incumbent business and regulators as they struggle to keep pace.

And all this as regulators and market operators, as well as the fossil fuel lobby, look to old solutions to new problems, and continue to play down the benefits and promise of these new technologies.

Smaller and smaller

The new technologies will allow for smaller and smaller participants to transact energy in the retail and wholesale markets, through peer-to-peer rating and community-focused energy systems – such as micro-grids – and in some instances may by-pass some incumbents altogether.

Two of the closest observers of the transition of the energy utility business model have been Lawrence Orsini, the principal of US-based firm LO3, which has recently set up shop in Australia, and the team at Accenture Australia, led by Ann Burns and Simon Vardy.

The New York-based Orsini, who is in Australia to present at a major networks and utilities conference in Sydney this week, says the business models of utilities are being “shaken apart” by the changes in technology and the arrival of the “sharing” economy.

LO3 is involved in the Brooklyn micro-grid project in New York, part of their “reshaping the power vision” project, and in Germany. But he says the most interest has come from Australia, and several trials are expected to be announced in coming

In Brooklyn they want their electrons to be Brooklyn electrons

The Australia interest, he says, comes as a result of the uptake of solar, the anticipated boom in battery storage, high energy costs, and the fact that the grid has not been built to be resilient.

That latter comment may come as a shock to those who justified the massive spending on infrastructure in recent years on meeting the 99.998 per cent reliability standard that is designed to allow just 11 minutes of outage per customer a year.

But the South Australia blackout proved a lie to that. And rather than being the fault of wind energy, as many pretended, the experience has underlined the fragility of Australia’s reliance on large centralised generators and huge networks that transport the energy hundreds of even thousands of kilometres.

Transactive energy

Just about everyone agrees that the way to provide a more secure, and low cost grid, is to focus on localised energy, featuring local power and sharing – a concept that Orsini describes as “transactive energy.”

The blockchain technology is important because it can offer a “cryptographically secure”, distributed ledger that can track where electricity was generated, where it can travel to and who used it.

“There is no question about where you got your kilowatt hour, where it came from and how it was produced,” he says. It is transparent and secure, and will make it easier for new and smaller players to be involved, right down to the individual solar household. In effect, another major step towards the democratisation of energy.

As soon as you start paying for the real cost then the grid re-organises itself. You will want to pay for stuff that is closer

Orsini says his company is focused on the physical transaction of energy, not the financial transactions. The key, he says, is in the need for fast-acting load responses, storage, controllable generation and reaction time.

“So what we need is a transitive grid,” Orsini tells RenewEconomy in an interview. “We are going to hit a tipping point where this is going to shift very fast.

“Any energy system that is running high on renewables, in combination with non-renewables and storage, needs to move to a market model that recognizes the value of a “negawatt” (the power you don’t use) as well as the value of megawatt. The grid architecture will change very quickly.”

Valuable lessons

Orsini says the Brooklyn project has already provided some valuable lessons, in particularly the interest from consumers in where their electric power comes from.

“I was skeptical that people would have an interest in where energy is coming from, but Brooklyn shook that up a bit. I didn’t understand how much of  a driver was renewable energy, for solar on the rooftop, for community projects, and for their environmental benefits. In Brooklyn they want their electrons to be Brooklyn electrons.”

He says one of the biggest drivers in Australia will be location-based models for energy production, transportation and consumption.

“If you are buying your electricity from far away – and if you not paying for that cost, then it is socialised. You never see the real cost. As soon as you start paying for the real cost then the grid re-organises itself. You will want to pay for stuff that is closer. We used to have no choice but to have a centralised, monopoly grid, but we don’t need to do that any more.”

Blockchain has the capacity to “cut out the middle men” which may include retailers and generators

Orsini points to research by consultancy firm Accenture that suggests that 80 per cent of consumers want to “participate” in the market, not as active traders perhaps but certainly not as passive as they had been.

“I still don’t know that that computes with me,” Orsini admitted.

RenewEconomy recently interviewed Accenture energy experts Ann Burns and Simon Vardy, who are in no doubt about the shift in attitude of consumers – enabled by solar and storage – and the role that blockchain will play in that.

“The consumer will drive the agenda more and more,” says Burns. Sharing and community focused energy is “not something that can be prevented.”

Vardy says that blockchain has the capacity to “cut out the middle men” which may include retailers and generators, and the uptake will be driven by the changing consumer landscape and the emergence of the “millennial” as the largest consumer cohort – a position they will reach by 2020.

    Seems to me that there is one fundamental difference between the “blockchain” software used for financial purposes and for locally distributed power: there are no limits for financial transactions, but there are severe restrictions in local distribution networks.

    Take a suburb where (then)thousands of people live, but work in town, 10-100 km away. During the day, few people are left in the suburb with minimum power use. Solar production is on its highest, so must be redistributed, either locally in home batteries or to towns or industry, where most of the energy use is at that moment.

    The current distribution networks are laid down for a certain maximum load (one-way, but can be used two-way). If 1 in 4 houses have maximum roof solar, that will go fine, if that gets more dense, one need either in-house batteries or a much higher local distribution capacity. How will the local distribution restriction be incorporated in the software?

    Didn’t look at the date that this article was published, assumed it was recent, as it was second on the “popular on EP” list… “Popular” seems a bit overblown, as my comment was the first in over two months…

    • Karel Beckman says

      There is nothing “overblown” about it. It hits the most popular if it is read the most during the past week. Sometimes old articles pop up because they are shared by people. Just because an article is a few months old it doesn’t mean it’s not worth reading. Moreover, the number of comments has no relation to the number of reads or shares. Some very popular articles have no comments because they don’t lend themselves to comments. Besides, most readers don’t comment, there is a relatively limited group that does so.

    Utilities can survive only one way: they should build local energy plants that use Sun and Wind. My WindSolars would be able to deliver electricity 24/365, due to built in energy storage of great capacity and very cheap too. They would be able to store all surplus energy that Grid usually cannot acceppt, if it is produced in Low Consumption Periods. My new WPSs that would be able to produce at least 144 times more electricity from same wind, utilized now only by ONE standard model WPS also do not depend on Grid as they are self starting. WindSolars would be relatively close one to another and producing 10 to 20 MW per hour or less, so they can be connected one to another and level energy with one another.
    Since their capacity would be extensible up to 720 MW per hour, they would be able to store all surplus energy say from hydro in high water accumulation state, when usually water is flushed unused in low consumption periods to lower pressure on Dams.
    So, if utilities start building them first, and they have money to do so, they would still be able to remain main supplier of electricity.
    Since production price would be underr 10$ per MW, they can cut market prices in half and still earn more money than before. Plus earning Carbon Credits and avoiding polution taxes. With lot of cheap electricity even capturing CO2 would be cheap, and it is valuable resource for making Carbon Products, whose production also need lot of electricity. Since WindSolars could be built into Skyscrapers and other buildings if scalled down, and they do not need large Grids, they would bring electricity even there where it was not economical to get with Grid extensions. Without huge loses in long distance electricity transport, wiich is 60% in my country, electricity would be still cheaper for consumers, and large consumers can have their own “Captive” WindSolars that can be on factory itself, houses for workers and so on. Built in Greenhouses would increase food production as well, and land can be cultivated using electric aricultural machines, too.
