Solar Connect was a townwide solar and battery trial linking households via a Virtual Power Plant (VPP). House­holds in the VPP shared solar and battery power in ways that benefited the Alice Springs grid and informed the opportunities for the next generation of more sustainable energy solutions.

In partnership with Territory Housing, the Alice Springs Future Grid installed 15 solar battery systems on public housing to ascertain the impact of public housing energy consumption behaviour into the Energy Grid.

It was recognised that solar has the effect of enabling those with the financial means to do so to reduce their power bills, while this project allowed these benefits to be shared with tenants. In addition, the Arid Lands Environment Centre led a Low-Socioeconomic study that presents baseline information on the challenges facing this section of the community in accessing direct benefits from renewable energy.

This is a subject of much discussion and study, and is even the focus of a current Australian Renewable Energy Agency (ARENA) funding opportunity. It does pose a looming waste management issue, with the design life of solar panels at 20 to 30 years, and many installed well over a decade ago. The International Renewable Energy Agency (IRENA) estimates there could be 60 to 78 million tons of photovoltaic panel waste accumulated globally by 2050. It also estimates the recyclable materials will be worth $15bn in recoverable value.

It is envisaged that recycling solar panels will create industry and employment opportunities, keep valuable resources out of landfill, help to retain rare elements, and prevent heavy metals leaching into the environment. There are a couple of companies working in this space in Australia.

All reputable installers are registered with the Clean Energy Council. You can find out more in the Consumer section of its website.

Plans are underway to build the world’s largest solar farm in the Northern Territory’s Barkly region, exporting the power via a High Voltage Direct Current (HVDC) cable. The $20bn project, known as SunCable, plans to send most of the power to Singapore, which relies on LNG for the majority of its electricity.

Producing green hydrogen (via renewable energy processes as opposed to fossil fuels) is another way to export solar. A National Hydrogen Strategy was developed by the COAG Energy Ministers and released in November 2019. It highlights the opportunity in the NT, given its proximity to Asia, and recommends a focus on exports and enhancing energy security in remote areas, amongst other market ideas.

There have been other projects around Australia carrying out investigations in many similar areas to Future Grid. The difference is that Future Grid looked at a series of interventions in aggregate and how they could integrate as a system on a technical, economic, and regulatory basis. This is what made Future Grid fundamentally different; it brought public utilities together with leading industry experts, and local organisations. We collaborated in a way that was simply not possible in other locations. For comparison, if we look to WA; Horizon Power has demonstrated many of the technical interventions we were working towards, but they are doing it in the context of being a vertically integrated energy supply company, so its activities don’t require complex engagement with other entities. In other areas, such as South Australia, there are fundamental differences in the market structure, which provide economic signals that are not available in the NT. What Future Grid did, which was different to other projects, is to work out how to bring parties and interventions together to collaborate.
