Stan,
 
Check the figures for Cape Wind Associates (Cape Cod).  If the plan is still 
130 turbines, peak power of 2 GW seems improbable as it requires 15+ MW 
windturbines.  The original plan was GE 3 MW wind turbines, totalling around 
400 MW.  While maximum size may have increased a little, I don't think anyone 
is making 15 MW windturbines.  (I have not followed their plans for a while, so 
there may be changes I'm unaware of)
 
Natural gas turbines could probably take up the wind slack.  I got to tour a 
DTE plant a few years ago.  Two coal fired boilers and steam turbines each 
producing 600 MW and 7 gas turbines each producing 100 MW on the same property 
(total plant, 1900 MW).  They ran the gas turbines selectively as peakers to 
take up demand, and tried to run the coal plants continuously.  The gas 
turbines can be started and stopped pretty quickly although you would have to 
keep one on spinning reserve at all times I imagine.
 
These are just details for your consideration.  I agree with your main points.  
Wind power is virtually unschedulable, and if you try to schedule them based on 
forecasts, you can't count on them to deliver.  At least in a desert, solar is 
pretty schedulable as you know when sunrise and sunset are.

Converting values to SI and resorting to the unit for power instead of using 
energy units and time units makes energy articles easier to read and compare 
numbers. Particularly if the rule for printing-significant-digits-only 
is observed. 
All this is observed in the attached, so-simplified, treatises. 
To get the joke in the "TR El", read the Denmark section in tthe "Wind" first.
