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.

REVS project completion

This week marked the completion of the REVS project – the largest demonstration of vehilce-to-grid technology in Australia and foundational research on the integration of electric vehicles into the grid and people’s lives.

FACTS – a Framework for an Australian Clean Transport Strategy

I was part of a team of 18 independent experts (academics) who developed a comprehensive framework for decarbonising the Australian transport sector in a manner consistent with international best practice (eg shifting trips to public and active transport) and climate science to keep warming within 1.5d.

Below are some takeout snapshots. The full report is available at transportfacts.org and a summary was published in The Conversation.

Providing electric vehicle charging at ANU

As life continues to return to the ANU campus we’re finally able to announce that we’re providing free electric vehicle charging – powered by the DERlab.

Vice Chancellor Professor Brian Schmidt said: “I see this as the first small step, or a precursor to having charging available more broadly on campus. I envision a set of EV parking spots will be rolled out across campus in the years to come so people can plug in and charge their EV while the sun is shining and the energy is cheap, rather than, like me, going home when the sun has set and plugging in.

“Here at ANU we are a community of 20,000 people, we have the opportunity to lead the way, implement our own knowledge and show the world how to do it. We will have to make some sacrifices to get ANU Below Zero by 2030 but our community is right behind it,” said Professor Schmidt.

Solar Analytics acquires SunTenants

Solar Analytics – which specialises in data and monitoring devices – has expanded its business into offering solar for renters, launching Solar for Rentals, following its acquisition of Sydney-based start-up SunTenants earlier in the year.

The Solar for Rentals offering includes a calculator that can be used by both tenants and landlords to estimate the value of a rooftop solar installation and determine what a “fair” increase to a property’s rent may be.

When paired with Solar Analytics system performance monitoring dashboard, Solar for Renters is able to provide a transparent platform for both landlords and tenants that should help breakdown the confusion that can come with installing a solar system on a rental property.

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.

Owners of electric vehicles to be paid to plug into the grid to help avoid blackouts

Electric vehicles can help keep the air clean in our cities – as we’ve seen recently with the reduction of traffic through COVID-19 lockdowns – but they face two obstacles.

In the short term they’re still expensive. In the long term charging millions of vehicles from the electricity grid presents challenges.

I’m part of a new project, launched today, that tackles both of these obstacles head-on, and it could mean owners earn more money than they’re likely to pay for charging their electric vehicles.
