A turbine decommissioning price depends on the full removal and restoration scope, not just tower demolition. Compare gross costs, salvage assumptions, exclusions and acceptance requirements separately.
The short answer: the scope determines the cost
There is no single current price that applies to every U.S. wind turbine. The DOE Wind Energy End-of-Service Guide identifies location and labor rates, turbine size, transportation, turbine count and material salvage rates as cost drivers. A blade-only processing quote cannot be compared directly with a whole-project decommissioning estimate.
Historic estimates in a public report are not today's company prices. An actionable budget needs the actual inventory, site conditions, required removal depth, receiving routes and restoration obligations. We do not publish an invented per-turbine rate.
Break the estimate into work packages
| Work package | What to clarify before comparing prices |
|---|---|
| Turbine removal | Turbine count, dimensions, condition, access and removal responsibilities |
| Blade management | Preparation, transport, receiving route and processing evidence |
| Metal and components | Separation, hauling, buyers and ownership of recovered material |
| Foundations and underground infrastructure | Required removal boundaries and treatment of concrete, rebar and cables |
| Roads and other infrastructure | What must be removed and what may remain |
| Site restoration | Backfill, grading, topsoil, drainage, decompaction or reseeding where required |
| Project closeout | Required inspections, records and owner or authority acceptance |
Some of these packages may be outside a particular proposal. Treat them as questions about scope, not assumptions that one contractor supplies everything.
Gross cost and net cost after salvage are different
Ask bidders to show removal and restoration costs separately from estimated salvage credits. Confirm who owns the steel, copper and other recoverable components, the basis of any estimated value, who pays handling and transport, and what happens if market prices or accepted quantities change. A projected salvage credit is not guaranteed income and does not mean the project pays for itself.
Foundation removal can change the comparison
DOE explains that removal depth depends on applicable requirements and future land use; some projects leave agreed below-ground infrastructure in place. Do not assume full extraction or use a nationwide depth rule. Obtain the relevant lease, approved decommissioning plan and authority requirements before comparing excavation and restoration prices.
Request comparable bids
- Give each bidder the same turbine and blade inventory, photographs and location
- Provide the required removal boundaries and restoration standard
- Ask for explicit inclusions, exclusions and assumptions
- Separate salvage estimates from the underlying work price
- Define treatment of unknown conditions and rejected materials
- Agree who signs off on completion and what evidence they require
Use our decommissioning and tower removal checklist. For wind turbine decommissioning, request a project review with the state, county, inventory and available scope documents.
