Power and Water Generation produces more than 1900GWh of electricity a year, using gas, diesel and solar technologies to power Territory towns and communities. Generation owns the majority of the major power stations located in the Territory.
Our total installed generation capacity is more than 615MW. Of the 615MW, the breakdown is 558MW Generation owned with 57MW under power purchase agreements with independent power producers.
Generation is the largest electricity producer in the Northern Territory power generation market. The scope and nature of our service delivery activities are based on safely, reliably and efficiently generating electricity to meet the needs of our customers.
Channel Island Power Station, near Darwin, is the Territory's largest at 322MW. It has eight gas turbine generators including two Rolls Royce units commissioned in 2011-12 and one steam turbine generator using the exhaust heat of two of the gas turbine generators. These are connected to Darwin-Katherine electricity network by 400km of 132 000 volt line.
Weddell Power Station adds up to 86MW to the Darwin-Katherine electricity network with two new 43MW gas turbine generators commissioned in 2008/2009. The interconnected Darwin - Katherine electricity network accounts for three quarters of the Territory's power generation capacity.
In 2010-11 Power and Water commissioned three dual fuel engines at the new Owen Springs Power Station, outside Alice Springs. The rural site has room for expansion, allowing the gradual retirement of equipment from the town-based Ron Goodin Power Station.
Tennant Creek and Yulara Power Stations are gas fuelled power stations utilising diesel as a backup fuel.
Generation operates six minor power stations in smaller townships (Borroloola, Elliott, Daly Waters, Timber Creek, Ti Tree and Kings Canyon) that are largely diesel-fuelled.
Generation also works in partnership with independent power producers to support renewable energy power generation initiatives.
