Frontier Energy Breaks Ground on WA’s Largest Solar-Battery Project Targeting 2028
Frontier Energy Clears Key Grid Hurdle for 130MW Waroona Stage Two Solar Project
Frontier Energy Waroona Stage Two has been deemed 'Ready to Progress' by Western Power, clearing a key grid connection gate for the 130MW solar and 80MW battery project 120km south of Perth.
Key Takeaways
- Western Power has deemed Waroona Stage Two 'Ready to Progress' under its Critical Projects Framework, opening the door to network studies and assessments on the way to an Access Offer.
- Stage Two already has Development Approval and completed key environmental studies, leaving grid connection as the main gating item.
- Stage One's substation and Landwehr Terminal cable, a combined cost of over $30 million, can be reused, which Frontier says means a 'materially reduced timeframe and cost' for Stage Two.
- Stage Two is planned at 130MW solar and 80MW of roughly eight-hour battery storage, closely mirroring fully funded Stage One, which has first generation scheduled for 2028.
- No Stage Two cost, funding position or Access Offer timeline was disclosed, and the priority benefit depends on Western Power's requirements being met.
