Power supply

Electricity provided to the major remote towns and remote communities is predominantly generated by diesel-fired power stations. IES Pty Ltd owns and operates 52 diesel-fired power  stations with an installed capacity of over 80 megawatts (MW).

Where the major remote towns and remote communities are in close proximity to existing electricity services, Power and Water purchases power through agreements with third-party suppliers.

Power and Water currently uses renewable energy systems at six communities with an installed capacity of almost 800 kilowatts (kW). These systems utilise a range of solar technologies, including both concentrating dishes and flat plate modules.

Meeting the growing demand for power

Power and Water aims to maintain reliable power services to residents in major remote towns and remote communities. This is achieved by ensuring that there is sufficient generation capacity in each community to meet the power demands in the event of a failure or routine maintenance of the largest generator on-site.

Maintaining fuel stocks

Diesel is the primary source of fuel for the power stations run by Power and Water in remote locations and ensuring sufficient supply of fuel is transported and stored securely on site is a major feat in logistics. Power and Water works closely with fuel contractors to overcome the obstacles of distance, access limitations and extreme climatic conditions, to make sure that the right amount of fuel is delivered at the right time and in the most cost-effective way.

Getting power to people

Power and Water manages more than 1,000 km of power distribution lines across the Territory. Power and Water’s operation philosophy is to ensure that there is sufficient capacity in the systems to maintain services to residents in the event of a failure or outage within the distribution system.

Power and Water also has an ongoing program to connect power distribution networks for major remote towns and remote communities which are in close proximity to one another. To date Power and Water has decommissioned five less efficient power stations through this grid connection program, which increases cost efficiencies and decreases greenhouse emissions.
