104 Fundamentals of Ocean Renewable Energy

FIG. 4.16 Energy production distribution for a typical year in the Block Island Wind Farm Project
(30 MW capacity). The computational details have been provided in Table 4.1.

PDF) is 130,105 MWh. Using method 2, the total energy production is
124,805 MWh.
8. Compute the capacity factor by dividing the energy output by the total
capacity of the project. Here, the total capacity of the project is 30 MW times
the number of hours in a year: 262,800 MWh.
Fig. 4.16 shows the distribution of the energy output. As we can see, the majority
of power is produced when the wind blows with a speed of 11 m/s at this site.
According to a report published by Deepwater Wind [7], the overall energy
production (on average) is 124,799 MWh, and the capacity factor is 47.5%. The
average wind speed is reported 9.69 m/s. These numbers are very close to what
we estimated in Table 4.1, given the assumptions that we made, and relative
simplicity of our approach.

4.4 MARINE SPATIAL PLANNING

Siting an offshore wind farm is a complicated process, in which the feasibility of
a project in several aspects such as technical (wind energy resource, foundation),
economical (cost-benefit analysis, levelized cost of energy), environmental/
