Major Projects

Planning for the Future - Power and Water Corporation's five year, $1Billion investment.

With the Territory booming ahead, Power and Water needs to be able to provide a growing residential, business and industrial community with reliable power, water and sewerage services.

We live and work in a tough environment with severe extremes in weather. It is an on going challenge to get services 'on the ground' where they are required and to meet current and future demand. Day to day power demand is expected to grow by 7.1% within 12 months (peak demand by 2.5%) and water by 1.5%.

The five year, $1Billion investment in upgrading and maintaining facilities is the largest investment in essential services in the Territory's history. Power and Water Corporation has allocated $592M for capital and $222M for repairs and maintenance initiatives under this program across power generation, power networks, water, sewerage and business services.

Major projects include:

$126.6 million for a new power station at Weddell to service Darwin and Palmerston
$25.0 million for Darwin Sewage Strategy - closing the Larrakeyah Outfall
$10.0 million to upgrade Ludmilla Waste Treatment Plant
$41.7 million for a new power station at Brewer and transmission line to Alice Springs
$12.5 million for undergrounding power in Darwin suburbs
$12.2 million for new power sub-station in Archer for Palmerston
$11.5 million for power upgrades in Katherine, Tennant Creek and Yulara
$8.5 million to raise Darwin River Dam by 1.3 m increasing capacity by 20%
$8.0 million upgrade to Howard East Borefield Stage 2 increasing capacity by 6%
$3.2 million upgrade to Roe Creek Borefield in Alice Springs

Current Major Projects:

Transmission Water Main to Palmerston
Power and Water Corporation is installing a new 4.2 kilometre transmission water main as part of its 2008 Capital Works Program. The main will extend from Howard Springs Road to Temple Terrace, then along Temple Terrace from the Stuart Highway to Roystonia Avenue.

Manton Dam Water Test Project
Power and Water Corporation will begin a project in May 2008 at Manton Dam to test the water quality in the dam under a range of conditions. The project will help Power and Water to deal with any water quality issues that may arise should the dam be called on to provide an emergency supply.

Construction of the Frances Bay Zone Substation
The $6.9M contract to construct the Frances Bay Zone Substation was awarded to Sitzler Bros (Darwin) following a competitive tendering process. Once completed, the Frances Bay Zone Substation will increase security of supply by providing an alternative source of electricity to the Darwin Central Business District. This substation will also help meet growing demand for electricity, due to new projects such as the Waterfront Development. It will be located near the Harbour View Plaza building.

Construction of the Archer Zone Substation
Construction will begin in the 2006-07 financial year on the Archer Zone Substation. This substation will improve reliability in the Palmerston area and is expected to be completed in 2007-08.

Raising the Height of Darwin River Dam
Raising the height of Darwin River Dam is required to provide additional water to meet increased demand in the Darwin, Palmerston and rural areas. Raising the 30 metre high Dam by up to 1.5 metres will increase available yield by around 20%. All existing downstream infrastructure, such as the pumpstation and rising mains are capable of supplying additional water, this raising the existing structure is an efficient and cost effective source of development option. Investigations in the potential to raise Darwin River Dam have indicated that it is technically and environmentally feasible to raise the existing wall up to 1.5 metres in height.

Undergrounding Power in Darwin
The Undergrounding Power Project has now been completed in Nightcliff with around 700 properties now having underground power. Work to underground the power supply to around 675 properties in Rapid Creek commenced in October 2006 with the first 343 properties due to be completed by mid-2008. The remaining properties are due to be completed by late 2008. Design work has commenced on Millner, which is the next suburb programmed for undergrounding power.

Future Gas Supply for Power Generation
A Gas Sale Agreement between the Power and Water Corporation and Eni Australia was finalised in late June 2006. This agreement means the Northern Territory's electricity needs will be met for the next 25 years, with the gas used to run power stations in all major centres.

Eni will extract the gas from the Blacktip Gas Field, which is located around 100km west of Wadeye in the Timor Sea.
