[pdf] For quick planning, expect a low-range project around $15,000–$40,000 for small off-grid setups, a mid-range of $40,000–$150,000 for modest on-grid systems, and $150,000–$500,000+ for larger commercial-scale installations. Commercial Projects Offer Best Economics: Utility-scale wind. Homeowners and businesses typically pay a broad range for wind turbine installation, driven by turbine size, site conditions, and permitting. This article breaks down the cost and price ranges to help builders estimate a project budget. For example, a wind turbine with a nameplate (rated) capacity of 1 MW could go for $1.
