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.

A Vir­tu­al Pow­er Plant (VPP) is typ­i­cal­ly a col­lec­tion of solar and bat­tery stor­age sys­tems that work togeth­er to allow coordinated control of their energy.

VPPs use smart technology to control the energy flow to and from the grid on demand – benefitting the household, grid and the community.

The VPP in Alice Springs, known as Solar Connect, invited households with rooftop solar, with or without a battery to join the trial.

The experience in developing the trial, engaging participants and running the trial, provided valuable insights to the project stakeholders on what future trials might look like. The functionality developed during the trial provided the opportunity to investigates these new technologies and concepts – that is, this was the first VPP in the NT, and it allowed the participants to share energy and data in new ways.

The trial became operational in October 2022 and ended in October 2023.

Alice Springs Future Grid created the Northern Territory’s first residential Virtual Power Plant (VPP). The trial looked at how a VPP can help keep the grid stable while increasing the amount of clean energy in the Alice Springs power system.

The VPP was part of a suite of innovative trials, models and investigations that looked at how to keep the Alice Springs network within voltage limits, reduce the reliance on gas power generation, and help the Northern Territory to reach 50% renewable energy by 2030.

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.

Knowledge sharing is a key focus for (funding agency) ARENA, and the Future Grid project has a prominent knowledge sharing plan, delivery of which is led by CSIRO. Reports generated through the project are hosted on the ARENA Project Page for Future Grid. It is recognised that lessons learnt in Alice Springs can be scaled-up and applied to other grids, such as the Darwin-Katherine Interconnected System (DKIS) and the National Electricity Market on Australia’s East Coast. The project’s main target audience is industry and government, so it is expected these entities will be the primary conduit through which lessons learnt in Alice Springs are applied elsewhere.

The Future Grid project (and the Roadmap to 2030) has significant value nationally because some of the research and findings demonstrated in the Roadmap, set out ways different parts of the power system will need to work together in the future. A key characteristic of Alice Springs is that it is small enough that the opportunity exists to test and validate interventions, but big enough that the results have direct applicability across a range of different systems and grids in Australia. To this end, Alice Springs is sometimes said to be “small enough to manage but big enough to matter”.

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.
