North West Interconnected System
The North West Interconnected System (NWIS) is the Pilbara’s main grid, servicing around 20% of the region's electricity needs. It connects major towns and industrial areas, powering key mining and export operations, as well as some local communities.
Unlike the South West Interconnected System, the NWIS is not truly interconnected. Instead, it is made up of several loosely connected networks owned and operated by different parties, rather than a single, centrally managed system.

The Pilbara Energy Transition Plan
The Pilbara is a special place. It’s among the oldest continuously inhabited regions on Earth, larger than many countries, and is home to more than 700 Aboriginal archaeological sites. It’s also Western Australia’s economic engine room. Hosting a large portion of our State’s resources industry, the Pilbara contributes almost one-fifth of WA’s total economic output each year.
With such large and important mining, mineral processing and export operations in the region, decarbonising heavy industry in the Pilbara is essential for meeting the State Government’s commitment to net zero carbon emissions by 2050.
The Pilbara Energy Transition (PET) Plan is facilitating new common use transmission infrastructure to unlock high-quality renewable energy resources and drive decarbonisation in the Pilbara.
