As a renewable energy specialist with extensive experience in the wind power sector, I can provide you with a detailed breakdown of the costs associated with building a wind turbine. The cost of constructing a wind turbine can vary significantly based on several factors, including turbine size, location, technology, and the local regulatory environment.

Turbine Size and Capacity
The cost of a wind turbine is closely tied to its size and capacity. Larger turbines with higher capacity factors are typically more expensive to build but can generate more power over their operational lifetime. As you mentioned, utility-scale wind turbines can range from about $1.3 million to $2.2 million per megawatt (MW) of nameplate capacity. This means that a turbine with a capacity of 2 MW, which is quite common in commercial installations, would cost approximately $3 to $4 million installed.

Technology and Efficiency
The efficiency and technology of the turbine also play a significant role in determining its cost. Advanced turbine designs that can capture more wind energy and operate at lower wind speeds are generally more expensive. However, these turbines can also offer better return on investment due to their higher efficiency and longer lifespan.

Location
The geographical location of the wind farm is another critical factor. The cost of land acquisition, access to transmission lines, and the local climate can all impact the overall cost. Offshore wind turbines, for example, are more expensive to build and maintain due to the logistical challenges and harsher conditions compared to onshore turbines.

Regulatory Environment
Government policies and incentives can also influence the cost of building a wind turbine. Tax credits, grants, and feed-in tariffs can reduce the upfront capital cost for developers. Conversely, regulatory hurdles and delays can increase costs and timelines.

Operational and Maintenance Costs
In addition to the initial construction costs, it's important to consider the operational and maintenance (O&M) costs over the turbine's lifespan. These costs can include routine maintenance, repairs, and replacement of parts. The O&M costs can vary depending on the turbine's age, condition, and the quality of maintenance services.

Supply Chain and Logistics
The supply chain and logistics also play a role in the cost of constructing a wind turbine. The availability and cost of raw materials, transportation, and skilled labor can all affect the final price.

Environmental Impact Assessments
Before construction can begin, an environmental impact assessment (EIA) is often required. This process can be costly and time-consuming, as it involves studies on the potential effects on local ecosystems, wildlife, and communities.

Financing
Lastly, the cost of financing the project can also add to the total cost. Interest rates, loan terms, and the developer's creditworthiness can all influence the financing costs.

In conclusion, the cost to build a wind turbine is a complex figure that depends on a multitude of factors. While the base cost per MW of capacity can provide a starting point, it's essential to consider all the additional costs and variables that can influence the final price.
