WA lands major milestones in 2025

Western Australia lands major milestones in 2025

This evening, we round out our Year in Review series and turn our attention to the milestones that shaped Western Australia’s Wholesale Electricity Market (WEM) in 2025.

• 💡 WEM peak renewable contribution 91.1%, 20 December, reflecting continued growth across rooftop and large-scale renewables
• 🔋 Rapid growth in battery capacity and utilisation, playing an increasingly critical role in balancing the system

2025 marked a pivotal year for the WEM, showing how WA’s power system is evolving to meet new demand patterns while renewable contribution records continue to rise.
