Resilient and renewable: Aiming for greater power resilience in Millaa Millaa

Post-storm or cyclone power cuts are hard to avoid. But we’re working towards solutions which help avoid them in the Millaa Millaa region and improve the reliability of power.

The University of Queensland has teamed up with the community of Millaa Millaa in Far North QLD to explore opportunities to improve this towns energy resilience following natural disasters such as cyclones.

The project team will work closely with our local proponents, the Millaa Lions Club to design and prepare a feasibility study that outlines an effective response to restoring minimum viable electricity supplies to residents in crisis.

Our aim is to use the feasibility study to source Federal funding that will enable the plan to be enacted and a small scale microgrid established to empower the town residents to act immediately following sever weather and restore small but vital levels of energy to power essential needs.

Toward this objective, we will be doing some energy monitoring around town to understand typical electrical loads and doing interviews with residents and businesses to understand their:

(a) experiences of power outages,
(b) thoughts on potential renewable solutions and
(c) current back-up generation capacity or other adaptation strategies you’ve used in the past

 

ARENA Feasibility Study Outcomes

Thank you everyone for your assistance and enthusiasm with this process. The feasibility study process determined there was not a sufficiently strong economic or social case to proceed further with either microgrid option. It was determined the economic returns possible from the battery's contribution to demand response over its lifetime would not be sufficient to cover the initial infrastructure investment and operational costs and replacement cost of the battery assuming a 20 year lifespan. Meaning that if a community battery was to be implemented, it risked becoming a stranded asset and a potential burden to the community as it neared its lifespan if replacement costs could not be met. Other contributing factors included the local network topography, where Millaa Millaa is not an end-of-feeder location, is not identified as a Worst Performing Feeder and certain options already exist for work-arounds the event of local outages, which limits appetite for the substantial co-investment required for a microgrid and community battery.

A second community workshop was held on 7th October 2022 in the Millaa Millaa CWA Hall where UQ representative Stephen Snow gave a debrief of the feasibility study process. Throughout this process we have loved working with the community, have been consistently surprised at the strength, warmth and willingness of the Millaa Millaa community and eagerness to engage in uncertain processes such as feasibility studies in the interests of positive change. A huge thanks to all the households and businesses who adopted energy monitors! A discussion was had over the study and also about different options for alternative funding sources. Part of our journey is documented in the short video below.

Public event

We ran a workshop at the Millaa Millaa CWA Hall at 7pm on Wednesday 23 March, 2022. The workshops slides are available here and a detailed summary of the meeting, questions asked and next steps is available here.

At this meeting we shared our ideas for how to increase Millaa's energy resilience through a small-scale microgrid and spent a considerable amount of time on discussions around different options and gathering local knowledge.

Thank you so much to everyone who attended, to the Lions and QCWA for hosting us and to Energy Consumers Australia, Ergon Energy and Councillor Dave Bilney for their support.

 

Project partners

This research is assisted greatly by Energy Consumers Australia who has generously provided funding for part of the energy monitoring associated with this project. We now have energy monitoring operational on five businesses and eight households (and counting), gathering vital energy data to determine load profiles in the town. In-kind support has also been received by DiusPowersensor and Phisaver.

What is a microgrid?

A microgrid is technology which connects and coordinates local energy resources to provide reliable and renewable electricity to an area. Grid-connected microgrids enable normal electricity supply under normal circumstances, but can disconnect from the larger electricity network and operate autonomously in the event of network outages (e.g. post cyclones, storms or other events). More information is available here and we provide links to several other Australian-based microgrid projects in our March 23rd Meeting Summary document here.

What does this entail?

Most viable microgrid options involve installing (or subsidising) solar PV and battery storage onto willing participants’ houses. These batteries communicate with the Microgrid and are coordinated to provide back-up power in the event of a network outage.

Microgrids can also incorporate other local generation assets such as existing solar PV installation or existing backup petrol generation. Several operational microgrids exist in Australia.

Importantly, as part of the feasibility study we want to explore and gather your feedback on different options, so make sure to get in touch, please click the "Register your interest" button on this webpage so we can get in touch.

Please adopt an energy monitor! Part of the technical feasibility process entails gathering an idea of typical electrical loads in the town and Energy Consumers Australia have assisted us in providing anyone who'd like one with a free Powersensor energy monitor (valued at $195) if you are happy to share your energy data with us. To apply for an energy monitor simply click the "Register your interest" button on this webpage. 

You’ll also see us occasionally on the the Millaa Matters Facebook group. Note: this group is a private group.
 

This study is approved by UQ’s Human Research Ethics unit, project number: HE002515.
