Wind farms: Success factors
A number of critical issues can mean success or failure of a wind farm
development:
› Wind resource
› Land access (support by landowners)
› Capital cost
› Connection access: (cost, loss factor, grid capacity)
› Wind farm scale (to absorb certain fixed cost)
› O&M costs (typically only around 2% of capital cost per year)
