Decommissioning wind turbines is costly proposition

Our financially strapped towns and land leasers must not expect debt-ridden NYS [or anyone] to bail them out for insufficient decommissioning funds for end-of-life wind and solar projects.
Reported decommissioning costs are highly speculative, poorly understood and depend on the project’s design, location, the specific time of decommissioning and variations in disposal and recycling methods.
Published in August 2025, the report titled “Assessment of Decommissioning Costs and Financing Models for Onshore Wind Turbines” by researchers from the Finnish Environment Institute estimates minimum total costs per turbine at E 929,500, escalating to a maximum of E 1,509,000. “This starkly contrasts with typical industry claims of E 100,000 to E 200,000 per turbine, which often ignore site-specific factors like terrain, soil conditions, and regulatory requirements for hazardous material handling.” The study warns of a future decommissioning crisis as wind farms reach the end of their 20-year lifespans, potentially leaving governments, landowners, and taxpayers saddled with massive bills if decommissioning funds are inadequate.
