Wind Dependability

Randall Parker at Futurepundit does some heavy lifting on the North American Reliability Corporation (NERC) 2009 Summer Reliability Assessment:

...on page 52 of the PDF file I espy mention how in the US Midwest in one one grid region at peak demand time (hot summer afternoon) the worst case they've seen with wind generation was only 2% of nameplate capacity. That's pretty bad.

That's just one region, and it's probably a worst-case scenario, but...ouch.
