This document contains cost models for land-based and offshore wind turbines. For a land-based 1.5 MW turbine with a 70m rotor and 65m hub height, the turbine capital cost is $990,578 and the total installed cost is $1,364,330. For an offshore 3 MW turbine with a 90m rotor and 80m hub height, the turbine capital cost is $2,263,103 and the total installed cost is $5,282,529. The document provides cost breakdowns by turbine component and balance of station costs for both configurations.
