Wind is not a positively dispatchable power source. A wind turbine is not a functional substitute for a nuclear, hydroelectric, gas or coal station, all of which can produce power *when asked to do so*.
Grid-clearance auctions and other market pricing mechanisms VALUE positively dispatchable power at several times that of wind. Forget COST for a minute and think about VALUE to grid operations. Here in Ontario wind is paid a CAD$135 feed-in-tariff when the average production power VALUE is more like CAD$25. (Yes we are a slightly extreme case..)
Statistics like LCOE are just accounting games, that do not include grid-operational factors.
Photovoltaic ("solar") power may have a role to play, but the laws of our universe completely preclude the possibility of wind power ever being a useful, practical, economic contributor to large national grids; EVER. It's not even a remote possibility. On a little island somewhere, maybe.
