Exploring microgirds in the Australian contex

Intuitively it makes sense that microgrids are a good idea. There are many of us that want that to be the case and for good reason. They have the potential to bolster local resilience, increase utilisation of renewable energy sources and give a sense of autonomy back to communities.

One of BSGIP’s most substantial pieces of research is drawing to a close. The Southcoast microgrid Reliability Feasibility (SµRF) project is a $3.1 m transdisciplinary project that explores the challenges and benefits of microgrids within an Australian context. Set within the New South Wales south coast shire of Eurobodalla, a region devastated by the 2019-2020 Black Summer, the project took a deep dive into this technology and how it could be integrated into today’s complex and multifaceted energy system.

This article focuses on two recently published reports; a technical report that lays out a number of scenarios using real-world data applied to selected sites, and a social science report examining governance, social and regulatory issues under the current system.

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.

The clean energy revolution isn’t a techno-fix – it needs to be guided by communities’ local needs

New piece in The Conversation

Context is everything

Under the previous federal government, Australia’s approach to emissions reduction was narrow and technology-centred.

The new Labor government – elected on the promise of climate action – has the opportunity to move to a community-based approach. This should ensure any new infrastructure integrates with people’s lives, values, and aspirations.

Such an approach requires proponents and funding bodies (both government and private) to genuinely listen to communities’ needs – right from the early design stage.

If local circumstances are not considered, a trial can be plagued with problems.

PhD opening – Clean energy solutions on the Great Barrier Reef

We are looking for a PhD scholar to work as part of a multi-party project on cooling – and thereby saving – the Great Barrier Reef.

The PhD project will contribute to the development of clean energy systems that power the equipment that increases the thickness of marine clouds above the reef. These systems may feature solar photovoltaics, wind power, bio fuels, wave power, batteries and other technologies. The project will assess the technical, economic, and social feasibility of these technologies and design systems to meet the needs of the reef cooling applications.

The student will work closely with the Battery Storage and Grid Integration Program at ANU (www.bsgip.com), as well as researchers at Southern Cross University and the broader Reef Restoration and Adaptation Program (see https://gbrrestoration.org/program/cooling-and-shading/).

Full application details are here: https://cecs.anu.edu.au/research/student-research-projects/clean-energy-solutions-great-barrier-reef-phd-project-0

Feature on ABC TV Catalyst program – a childhood dream

ABC TV’s Catalyst program was one of my favorite TV shows growing up, so it was a bit of a dream to get to be a part of the recent episode about the transformation of the electricity system.

The episode did a fantastic job, covering a huge range of the interesting developments underway across the system and the country, explaining the crucial facts and trends, and presenting everything in interesting, engaging and understandable ways.

So, I’d highly recommend giving watching here https://www.abc.net.au/catalyst/the-grid-powering-the-future/13491654

One Step Off The Grid – SuRF project announcement

A new project led by the Australian National University will assess the feasibility of transitioning regional New South Wales communities from grids exposed to bushfires and other natural disasters to a resilient network of islandable renewables and battery-based microgrids.

The Southcoast Microgrid Reliability Feasibility (SµRF) project was last week named as one of 20 projects around Australia to be awarded a share of $25.6 million in funding via round two of the federal government’s Regional and Remote Communities Reliability Fund.

The project is being led the Battery Storage and Grid Integration Program at ANU in partnership with the Southcoast Health and Sustainability Alliance (SHASA), network company Essential Energy, and technology company Zepben.

New project: Southcoast Microgrid Reliability Feasibility (SµRF)

The Battery Storage and Grid Integration Program at the Australian National University, along with project partners Southcoast Health and Sustainability Alliance, network operator Essential Energy, and technology company Zepben, are delighted by news of successful project funding under the Regional and Remote Communities Reliability Fund (RRCRF) – microgrids 2020-21. 

The Southcoast Microgrid Reliability Feasibility (SµRF) project will engage NSW South Coast Eurobodalla residents, businesses, and Essential Energy in planning the transition from a bushfire exposed grid to a resilient grid of islandable microgrids.  

The project partners will receive $3.125M in funding over three years under the RRCRF to: 

  • conduct community-led design of future energy systems, quantifying the value of reliability;  
  • model the operation of eight microgrids across the region using high-resolution monitoring data and develop a holistic assessment of implementation costs; and 
  • explore business models and regulatory innovations to improve feasibility implementation.
