Cost competitiveness isn't the only feasibility factor relevant to planning wind farms. Energy providers need to consider the capacity of the transmission grid that serves a proposed wind project. Lack of convenient transmission lines was the Achilles heel in T. Boone Pickens' plan for a giant wind farm in Texas. Wind power enthusiasts in China have yet to figure this out. China's vaunted leadership in building wind installations may prove meaningless if grid upgrades lag behind new generation. Wind power is a waste without the grid lines to bring it to market.
Utilities planning wind projects should tread carefully. All of the relevant ducks need to be in a row - including enablers like transmission infrastructure and environmental considerations - before a green energy project gets a green light.
