The local government of Western Australia (Australia) has launched its Plan for Affordable Energy, which targets 75% renewable generation in the state’s main grid by 2030-2031 (Western Australian government press release, 27/10/2026). The plan aims to support the South West Interconnected System (SWIS) grid among the retirement of state-owned coal-fired generation expected by 2030. The plan focuses on delivering more renewable energy, backed by battery storage and gas to lower energy costs.
Key initiatives within the plan include:
- Transmission:AUD2.5bn (USD1.7bn) committed to the Clean Energy Link transmission infrastructure.
- Industrial support: a AUD150m (USD105m) for the Made in WA Energy Affordability Investment Program, open for applications from 27 October 2026, offering low-interest loans of up to AUD15m (USD11m) for manufacturers to install solar and battery systems and upgrade equipment.
- Gas: continued support for the domestic gas reservation policy and a future gas security strategy.
According to modelling undertaken by the Department of Energy and Economic Diversification, industrial energy prices could rise by 89% by 2032 without the plan’s initiatives.
Renewables in Western Australia rose from 14% of the state’s energy mix in 2017 to 40% in 2025.
