Offshore Wind Farm as Jamaica's Possible Primary Source of Renewable Energy

Abstract

The  island  of  Jamaica  has  been  exploring  energy  alternatives  in  a  bid  to  diversify the  energy  mix  and  reduce  the  cost  of  energy  to  the  final  consumer.  Extensive  research concentration  has  been  placed  on  Onshore  Wind  Farms  (OnWF)  and  potential  locations  across  the  island  yet  these  OnWF  have  been  able  to  supply  ~40MW  only  of  the over  600MW  of  electrical  energy  the  island  currently  demands.  This  research  carries out  preliminary  engineering  work  for  an  Offshore  Wind  Farm  (OWF)  capable  of supplying  360MW  of  energy  to  the  island’s  electricity  grid.  The  most  suitable  location for  the  OWF  in  Jamaican  waters  is  presented  along  with  selection  of  appropriate foundation  structure.  The  impact  of  waves  on  the  wind  turbines  is  analyzed  using models  and  soil  analysis,  meteorological  and  oceanographic  data  were  also  collected and  utilized.  The  research  presents  results  using  earth  station  data  on  the  average projected  wind  speed  of  9m/s  at  the  proposed  location,  prevalent  wind  direction  and grid  access.  The  capacity  of  each  wind  turbine  proposed  for  the  OWF  are  factored using  international  standards.  Results  are  a  farm  located  7km  offshore  in  13–25m depth  and  within  50km  grid  access.
