2023 Cost and Technical Parameters Review_Final Report

This report provides supporting information for the dataset and an overview of the scope, methodology, assumptions, and definition of terms used in the dataset and its development. [...] A representative cost has been selected for the hypothetical project from the data available, and cost certainty qualified based on the spread and quality of data available. [...] The accuracy / certainty of the cost estimates is targeted at +/- 30% based on the spread and quality of data available and our experience with the impact of the above factors. [...] The increase in rotor diameter allows more energy to be extracted from the resource at a given wind speed (compared to a smaller rotor, valid until the rated wind speed is reached), as the amount of energy that can be extracted by a wind turbine is proportional to the swept area of the rotor. [...] The main turbine-specific factor influencing capacity factor is the size of the rotor relative to the rated power output of the generator (i.e., the Specific Power).
