How does the Pilbara’s NWIS work?
Horizon Power owns and maintains a portion of the NWIS in the Pilbara, known as the ‘Horizon Power Pilbara coastal network’. It includes generation, transmission, and distribution assets connecting Port Hedland and Karratha.
The network links to the NWIS and operates alongside separately owned private industry networks.
Horizon Power has existing gas-fired generation supply agreements in place with Independent Power Providers (IPPs) in the Pilbara.
What's happening now?
Horizon Power has opened expressions of interest (EOI) calling for suitably qualified Independent Power Providers (IPPs) to propose new solutions to supply the region from 2030 – to ensure reliable supply, reduce emissions and drive the lowest generation costs in the region.
EOI respondents proposing a renewable energy solution and the ability to secure suitable land will be viewed favourably.
Procurement will prioritise local outcomes to maximise supplier involvement in the Pilbara's energy sector, aligning with the recent WA Industry Participation Strategy Ministerial Direction for energy Government Trading Enterprises.
Horizon Power is seeking expressions of interest from suitably qualified suppliers to help meet its long-term energy needs in the Pilbara. We are looking for innovative energy solutions that can deliver reliable, affordable and lower-emissions energy to the region’s communities and industry. The EOI is available on Tenders WA.
