Development of a methodology to assess the climate evolution and its impacts on wind energy

Maps of wind resources were used to develop a method of evaluating climatic changes and their potential impacts on wind energy resources. Global IPCC climate change scenarios were used to predict climatic conditions for the future, while past wind resource availability was simulated and validated using NCEP and NCAR reanalysis data as well as observed meteorological data from Environment Canada. The simulations were used to compare each 5-year period with a 50-year reference period. Regional scale climate change impacts were evaluated using a statistical dynamic down-scaling method. Advanced meteorological models were used to predict wind flow patterns across specific landscapes. The evolution of past wind resource availability was then simulated. Five-year wind resource simulations for a 50-year period were simulated at 25 km2 wind speeds at 80 m above the ground. Average wind speed variations were then evaluated. The method has been used to simulate 5-year periods within a 50-year reference period in New Brunswick. Further studies will be conducted to simulate future wind resources availability. tabs., figs.
