Overview
- RWE confirmed on Thursday that the Limondale battery has received formal sign‑off from the Australian Energy Market Operator and Transgrid to operate at full capacity following commissioning and compliance tests.
- The plant is a 50MW/400MWh system made up of 144 Tesla Megapacks that is registered to charge at 100MW and discharge at 50MW and can deliver registered discharge for more than eight hours.
- RWE registered Limondale with AEMO in September 2025, moved the project through hold‑point testing and completed grid‑compliance and performance tests before the operational approval.
- The battery sits beside RWE’s 249MW Limondale solar farm and will store excess renewable output to dispatch during peak demand, reducing stress on the network and cutting reliance on gas peaker plants for extended shortfalls.
- The project was the first to win an AEMO Services long‑term energy service agreement for long‑duration storage and highlights a policy push for multi‑hour assets even as experts urge diversification beyond lithium‑ion technology as the sector scales up.
