Wind turbine · 2026

What this outcome means
The FAA studied the proposal and concluded it would not be a hazard to air navigation. A no-hazard determination is not permanent — it carries an expiration date, and if the structure is not built by then the case has to be re-filed.
The proposal, in the filer's words
"Filing for a proposed wind project array. We can confirm that the project will proceed under a single final build scenario. Accordingly we request that none of the 2025 ASN (2025-WTE-1738:1893-OE) filings be terminated until the FAA has issued favorable determinations on these new submissions."
