NT & ACT Power & Wastewater Rules, by Council
Darwin and Palmerston both sit on Power and Water Corporation's northern grid specifically, one of the NT's three isolated networks (see the state-wide NT & ACT article for the full picture). The ACT has no local councils, so it's covered at the territory level, under Evoenergy's single network.
Darwin and Palmerston: the same grid, the same storm surge overlay
Both Darwin and Palmerston sit on Power and Water Corporation's northern network specifically — one of the NT's three isolated grids, distinct from the separate Tennant Creek and Alice Springs networks covered in our state article. Since the two councils are adjoining and share this same grid, the same standard export limits (5kW single-phase, 7kW three-phase for export-enabled systems) apply across both, subject to local network capacity. Both councils also share the same storm surge overlay consideration for their coastal and low-lying areas, which requires a planning permit regardless of whether a structure would otherwise be exempt.

The ACT: no local councils, one distributor, one utility
The ACT has no local government councils, so it's covered here at the territory level rather than council by council. Evoenergy is the sole electricity distributor for the whole territory, and Icon Water is the sole water and wastewater utility — both single, unified bodies rather than anything split by area within the ACT.

Frequently Asked Questions
Do Darwin and Palmerston share the same power grid?
Yes. Both sit on Power and Water Corporation's northern network, one of the NT's three isolated grids, distinct from the separate Tennant Creek and Alice Springs networks that serve the rest of the Territory.
Why doesn't this page list individual ACT councils?
Because the ACT has none - it's governed directly by the ACT Government rather than separate local government areas, so territory-wide rules are the only level that applies.
Does the storm surge overlay apply the same way in Darwin and Palmerston?
Yes. Both adjoining councils share the same NT Government mapped overlay for their coastal and low-lying areas, requiring a planning permit regardless of whether a structure would otherwise be exempt.
