Energy Vault Clears Permitting Hurdle for 125 MW Stoney Creek BESS in Australia

What happened

Energy Vault announced that the New South Wales Government granted State Significant Development Approval for its 125 MW / 1 GWh Stoney Creek Battery Energy Storage System in Narrabri, NSW. This approval clears the path for construction to begin on the project, which the company acquired in August 2025 through its subsidiary Stoney Creek BESS Pty Ltd for approximately AUD 4.0 million. The project is part of Energy Vault's strategy to build, own, and operate select storage assets, complementing its first owned projects Calistoga and Cross Trails expected to generate revenue in 2025. However, the company remains in a precarious financial position, having reported a net loss of $56.1 million in the first half of 2025 and facing NYSE minimum price compliance issues. While the approval is a positive regulatory milestone, it does not immediately address near-term cash burn or execution risks on existing projects.

Implication

Investors should view this approval as a minor positive, as it removes a key regulatory risk and signals progress on the company's owned-asset pipeline. However, the project is still in early stages; construction has not started, and revenue generation is likely several quarters, if not years, away. The company's liquidity remains constrained, with only $27.1 million in cash at the end of 2024 and recent equity raises at low prices. The NYSE minimum price compliance issue continues to hang over the stock, and any failure to cure could lead to delisting. Therefore, while the approval supports the long-term strategic shift toward asset ownership, it does not warrant a change in the HOLD rating until tangible execution milestones and improved financial metrics are demonstrated.

Thesis delta

The thesis that Energy Vault is transitioning to owned assets and recurring revenue gets incremental support from this regulatory approval. However, the core financial and compliance risks remain unchanged, and the HOLD stance is maintained pending evidence of successful commissioning and cash flow generation from the 2025 projects.
