Interesting UK Grid and wind:
Wind is currently producing the same energy as coal. Also note the depressed peaks in daily use as wind begins to generate (however it is olso necessary to allow for the fact the wind increased at the weekend=low use).
Note also the grid safely handled an increase from about 500MW to 5GW without incident
