Renewable Energy 

Renewable energy technologies use naturally replenishing sources of energy such as solar, wind, biomass, geothermal and hydro energy in generating power for our energy requirements.

Renewable energy systems are ideally suited for distributed generation. Northern Territory's ideal climatic conditions combined with the high diesel generation cost offer significant opportunities for utilising renewable energy, especially in its outback regions.

The Territory is endowed with abundant sunshine, and is in a unique position to harness its solar resource. Solar energy has been used in the Territory for many years in a variety of niche applications, including domestic hot water and telecommunications. With recent technological developments, solar energy is becoming increasingly viable in remote areas like pastoral stations and indigenous communities, particularly with the rebates that are currently available. Other renewable energy sources such as wind, biomass and micro-hydro are not as abundant in the Territory, and are site specific.

Solar power options

There are a variety of ways to convert solar energy into useful energy, including flat plate photovoltaics (solar panels), concentrator photovoltaics (PVs) and solar thermal systems. Flat plate and concentrator PVs convert sunshine directly into electricity. Solar thermal systems on the other hand first convert solar energy into heat, which is then converted into electricity. Flat plate PVs and, to a lesser extent, concentrator PVs are being used in commercial applications in the Territory.

Hybrid energy systems

Hybrid energy systems integrate solar panels, diesel generator, batteries, and an inverter into a single power supply system. Solar panels convert sunshine into electricity, which is stored in the batteries. The inverter converts battery output into single or three-phase AC. The diesel generator automatically cuts in when the batteries are low. The generator when running supplies the load and charges the batteries. The key is to find the right mix of solar array, diesel generator and battery capacity. Advantages of hybrid systems include:

• 24-hour power
• High reliability (more than one independent power source)
• Modular design (easy power system upgrade)
• Reduced fuel cost and maintenance cost
• Reduced noise and pollution

Solar Homes and Community Plan

Unprecedented growth under the Government's Solar Homes and Communities Plan has resulted in closure of this program by the Commonwealth and the immediate introduction of Solar Credits. [for further information].

Renewable Remote Power Generation Program (RRPGP)

The Renewable Remote Power Generation Program is closed to new applications in the Northern Territory.

As of 8.30 am Australian Eastern Standard Time on Monday 22 June, pre-purchase applications are no longer being accepted for the Renewable Remote Power Generation Program.

All pre-purchase applications submitted to the relevant state program administrator prior to this will be assessed according to the program guidelines.

Please note this only affects pre-purchase applications. The deadline for rebate applications is provided on your pre-purchase approval letter.
