| Land-based wind farm Capital cost per 1 MW installed*: $1.65M (1 MW nameplate capacity) Realized Cost: $4.6M per 1 MW generated (CF=36%) Obstacles: Difficulty in energy delivery, new transmission lines are needed, siting and permitting challenges, installation is time consuming and expensive requiring substantial on-site assembly |
| Shallow water offshore wind farm Capital cost per 1 MW installed*: $2.4M (1 MW nameplate capacity) Realized Cost: $4.0M per 1 MW generated (CF=60%) Obstacles: Assembly is piece by piece on site, high cost of foundation preparation, high cost of maintenance Advantage: Close proximity to consumption centers, strong winds |
HighSeasWind Deep-Sea Energy System (wind + waves) lower cost-of-energy, quicker deployment Capital cost per 1 MW installed: $2.0M** Realized Cost: $2.66M per 1 MW generated (CF=60% wind + 15% waves) Advantage: Low cost-of-energy, assembly in shipyard, simple deployment, installation and maintenance, closeness to centers of energy consumption, best winds, wave power |

| ©2013 HighSeasWind |
| The realized capital cost of the HighSeasWind power plant is 34% and 42% less than that of shallow-water and land-based wind power plants, respectively. Further cost reductions will be attained through ongoing improvements in mass production and maintenance methods. |
| Glossary Capital cost per 1 MW installed: The cost of wind turbine manufacturing and installation per 1 MW of nameplate capacity Nameplate Capacity: The highest power output a turbine is capable of generating Capacity Factor CF: Power output generated by a wind turbine as a percentage of the nameplate capacity, and averaged over a long time (at least 1 year) Realized Cost: Wind turbine’s capital cost per 1 MW of the actually generated average power output |
