GE and Lake Erie Energy Development Corporation Announce Great Lakes Offshore Wind Partnership at AWEA

  • DALLAS - GE and Lake Erie Energy Development Corporation (LEEDCo) of Northern Ohio announced today a long-term partnership beginning with the development of the first fresh water offshore wind farm in the US and involving a broad range of other initiatives. Under the new partnership GE will provide direct-drive wind turbines to LEEDCo's 20 megawatt offshore wind project in the Ohio waters of Lake Erie. The partnership and project is a significant step towards accelerating the deployment of offshore wind in the Great Lakes.



A 3-D model



Log10z0 for Cleveland area, lake z0=2x10-4m, upstream z0 = 0.05m contours are for log10z0= -3,-2,-1,0.



3-D model results, 80m wind speed for S flow near Cleveland CRIB site, Geostrophic wind speed 15 ms-1.





Conclusions

  • Offshore wind farms in the Great Lakes will be in place in shallow areas within a few years.

  • Offshore turbine installation is expensive so a good wind resource is essential, 73 = 343, 83 = 512, 93 = 729.

  • A long over-water fetch is needed before 80-m height winds reach equilibrium, over-water values.

  • For predominant winds from SW the northern half of the lakes have longer fetches over water……..
