There are three power networks, or
electricity grids, in the NT, with each network the
Australian Energy Regulator managing investment and efficiency, while PowerWater manages the day-to-day-operations. These networks are: • The northern network, covering the area from
Darwin in the north, to south of
Katherine, servicing around 150,000 people • The
Tennant Creek network services around 7,000 people in and around Tennant Creek • The southern electrical grid services the
Alice Springs area, servicing around 28,000 people
Power stations owned by PowerWater include the
Channel Island Power Station, on
Darwin Harbour's
Middle Arm, which is the largest power station in the Northern Territory, and the
Ron Goodin Power Station at
Alice Springs, the second-largest power station. The
Katherine Power Station and the
Berrimah Power Station are linked to the
Channel Island Power Station. The
Darwin–
Katherine system links from the Channel Island Power Station to Berrimah and Katherine power stations. Other power stations in the territory include the
McArthur River Power Station, the
Tennant Creek Power Station, the
Brewer Estate Power Station, and the
Yulara Power Station. The
Weddell Power Station was constructed in 2008–2014. The first two generators came on line in 2008–2009. The third generator was due to be completed in 2011–2012 but did not get commissioned until 2014. The power station added 30% capacity to Darwin's power supply. ==Water==
