Watt equity? Australians deserve a Basic Energy Right

This essay was first published in Australian Quarterly 95.3, Australia’s Longest running public affairs magazine, published by Australian Institute for Policy and Science https://aips.net.au/aq-magazine/current-edition/

Within the energy industry there is a popular, feel-good refrain that the energy transition will deliver a system that is ‘democratised’, in addition to being ‘decarbonised’, ‘digitised’, and ‘decentralised’. Here democratised is used as an umbrella term for a broad suite of desirable values: fair, just, equitable. Yet the way in which democratisation is envisioned to occur is, in contrast, blinkered – households are seen to gain political power as a consequence of their generating and controlling electrical power from rooftop solar, batteries, and electric vehicles – but what about those without?

This prevailing narrative of democratisation overlooks, amongst other things, the connection between privilege and ownership of these technologies, and the structural realities of social, as well as techno-economic, power. In particular, it ignores the systemic effects of managing energy through markets and, consequently, ignoring energy’s role as an essential service underpinning modern life.

The starting point of this essay is that the energy transition is not on track to improve equity. This is because equity will only be improved if it is prioritised above competing values, such as profit, in the millions of design choices that constitute the transition.

Such prioritisation is impossible within the existing (artificially) constrained policy landscape, in which the only options are those within the framework of indistinguishable individuals interacting through a market. This eliminates any space for unequal redistribution in recognition of the differing circumstances within the collective, and thereby contributions towards equity.

Progress towards equity rests on expanding the policy imagination. This essay offers one such suggestion: the establishment of a Basic Energy Right that provides all households with a modest amount of energy free of charge to meet their essential needs.

Response to Saul Griffith’s “The Wires That Bind”

This correspondence was originally published in the June 2023 edition of the Quarterly Essay, in response to the March 2023 edition by Saul Griffith.


While the pivotal role of electrification in decarbonisation has been understood for decades, it has rarely been described as vividly or enthusiastically as by Saul Griffith in The Wires That Bind. Griffith recognises that electrification is a story, at its heart, not about decarbonisation but about cleaning the air in our kitchens and streets, improving the liveability of our homes and communities, and “keeping wealth in our households and communities” – and nation. In short, electrification is a story about a better future.

While attuned to this human story of electrification, Griffith is, at heart, an engineer so it’s no surprise that The Wires That Bind is packed full of figures. Emissions are carved up, the grid is mapped and fossil machines are counted. This achieves Griffith’s goal of “clarity about the job in front of us” and complements his persuasive case for electrifying everything. The question that remains is: how can the transition best be accelerated and steered towards just and enduring outcomes?

Community batteries are popular – but we have to make sure they actually help share power

New article in The Conversation today. Excerpt below.


The idea is for these batteries to reduce carbon emissions and energy bills while benefiting all energy users nearby, rather than only those with access to rooftop solar. These are great ambitions – small wonder they’ve proven a hit.

But the success of these batteries is far from certain.

Over the last four years, our research has found two areas we have to fix to maximise the chances these batteries actually do what we want them to do.

First, we need greater clarity on how we decide whether community batteries are a good investment.

Second, we need better measurement and evaluation of what these batteries actually contribute to the grid and to energy users.


In a new discussion paper, this article’s lead author argues the primary purpose of community batteries ought to be addressing constraint in the local electricity grid. This reiterates a consistent finding from our research.

While this sounds reasonable, community batteries aren’t the only option to fix local grid issues. That means we should only turn to them where they are clearly better than the alternatives, such as upgrading transformers.

What about storing solar and shoring up the grid? These tasks may be done more efficiently and with less environmental impact with grid-scale batteries, pumped hydro or electric vehicle batteries.

And what about sharing the benefits of solar with people who can’t afford an array or who have nowhere to put one? While this vision is in line with public sentiment, the complexity of the privatised energy system makes it very difficult to redistribute financial benefits.

Community batteries are also no panacea for the desire of people to see and be included in national planning for the decarbonisation transition. An inclusive planning process can address uncertainties in how the transition will affect us and our communities and ensure it upholds public values.

Time will tell if the newly announced Net Zero Authority will deliver this.

Neighbourhood batteries in Australia: Anticipating questions of value conflict and (in)justice

We have a new paper published today in Energy Research & Social Science.

Highlights

  • Energy professionals and citizens hold diverse values on algorithm design, governance and the energy transition generally.
  • Differences in how values are interpreted and which values are emphasised suggest future points of conflict (and injustice).
  • Systemic issues raised both down and upstream of the technology suggest distributed responsability ill suited to centralised governance.
  • Our focus on responsibility and justice reorients the problem to re-design rather than accommodation.

Local network pricing and community storage a powerful combo: ANU

If networks could charge for localised use of their service, all customers in areas with high PV and community-scale batteries would pay lower bills … with no cost to the network, research shows.

Is rooftop solar a problem in the suburbs? Apparently so, with rising PV exports prompting falls in feed-in tariffs, plans for export charges in Adelaide and deployment of community-scale batteries in many cities.

As the grid transitions away from coal, it seems as though rooftop solar is part of the solution and part of the problem at the same time. Is there a simple solution that could see all that excess solar energy shared equitably and leave customers better off?

Yes, there is. Or there could be, if networks were allowed more flexibility in how they charge for their services.

Obey your master … how algorithms can steer a neighbourhood battery

Ecogeneration interview about our Nature Energy paper on battery algorithms

Research shows that if energy professionals and customers agree on what they expect a community battery to do, engineers can write performance algorithms to suit those objectives.

Can you trust a battery to make the best decisions about when to charge and discharge? It depends who owns it, for a start, but most of all it depends who wrote the code that is its book of commands.

As community batteries are deployed to manage solar exports and calm grid disturbances, researchers at the Australian National University wanted to understand the degree to which these assets can be bent to serve their owners or the communities they are plonked in the middle of.

“How an electric vehicle or a battery operates in your home, these things are governed by algorithms coded up by humans,” says ANU battery storage and grid integration research leader Bjorn Sturmberg. “They are not governed by the physics of spinning machines, which is traditionally what we have built our energy system around.”

Applying responsible algorithm design to neighbourhood-scale batteries in Australia

Our new paper in Nature Energy asks fundamental questions of what values and biases algorithms are encoding into our digital energy system.

Abstract below:
The digital energy era presents at least three systemic concerns to the design and operation of algorithms: bias of considerations towards the easily quantifiable; inhibition of explainability; and undermining of trust and inclusion, as well as energy users’ autonomy and control. Here we examine these tensions through an interdisciplinary study that reveals the diversity of possible algorithms and their accompanying material effects, focused on neighbourhood-scale batteries (NSBs) in Australia. We conducted qualitative research with energy sector professionals and citizens to understand the range of perceived benefits and risks of NSBs and the algorithms that drive their behaviour. Issues raised by stakeholders were integrated into NSB optimization algorithms whose effects on NSB owners and customers were quantified through techno-economic modelling. Our results show the allocation of benefits and risks vary considerably between different algorithm designs. This indicates a need to improve energy algorithm governance, enabling accountability and responsiveness across the design and use of algorithms so that the digitization of energy technology does not lead to adverse public outcomes.
