Microgrids, or stand-alone power systems, overseen by IES (Indigenous Essential Services) have a target of 70% by 2030.

IES is a subsidiary of Power and Water Corporation. It services 72 remote communities and 66 outstations across the NT. In total there are 430 homelands and outstations in the NT. 130 renewable energy systems were installed by Bushlight, with many more funded through other programs. This means there will be renewable energy generated which is not counted in the target, but the amount is fairly limited.

You don’t need 3-phase power to charge an EV. In fact, you can purchase charging cables that plug into a standard domestic socket. The most common way to charge an EV is via a "type 2" charger, and many EV drivers will opt to have a charging point installed in their home. A 3-phase connection will charge your car more quickly. A single phase type 2 connection will be slower than 3-phase but faster than your standard household sockets. Your local solar installer or electrician can assist with questions specific to your case. The cost of the charge will depend on the general cost of electricity, the capacity of the vehicle’s batteries, and whether you’re incorporating solar power. A fuel cost savings calculator can be found on myelectriccar.com.au, with plentiful similar resources available elsewhere online.

There are enough chargers along the highway to comfortably travel the length of Australia. There are a surprising number of charging points all over Australia, including in some incredibly remote locations, such as Kiwirrkurra, which is one of the most remote settlements on the planet! It is easy to view the full range of charging points on the app PlugShare.

Many people in the Northern Territory rely upon off-grid power systems, especially in very remote settlements such as outstations and ranger stations. The Alice Springs grid provides interesting challenges because it is isolated, unlike the National Electricity Market which connects jurisdictions from Queensland to South Australia, including Tasmania. The more customers and generators that are connected to a grid, the fewer challenges are faced in maintaining grid stability. Therefore, removing yourself from the grid when you have the choice to be connected is not of any benefit to the community.

With solar PV and batteries it is technically possible to go off-grid, but Alice Springs residents would need a very big battery or backup diesel generator to cover occasions where there is limited sun for consecutive days. The most common option is to install PV and BESS in proportion to household needs, and let the grid come to the rescue when its needed. In the future, plentiful PV and BESS will create a very resilient system, because it’s highly unlikely that they could all fail at once. For most people it is not financially viable to go off-grid, but as centralised energy generation incorporates a growing proportion of renewables, it means everyone will eventually be provided with cleaner energy.

The Future Grid car was an electric vehicle (a Nissan Leaf) and there were individuals in the team and community who were highly enthused about this technology. However, operating within a constrained budget and timeline, electric vehicles or related trials were not considered as part of the project. The team designed a series of interdependent activities that served to consider immediate issues in the system and support further renewable energy penetration into the Alice Springs grid in a cost-effective and realistic way. These interventions made use of and optimise existing grid infrastructure, which is a valuable public asset. The Future Grid team always welcomed any future or parallel projects that supported the increased use of electric vehicles in Alice Springs or focused on the integration of this technology as another means of supporting the grid.
