Comparison of areas of high quality wind resources and geology compatible with CAES
(suitable for mined rock caverns eliminated due to high estimated cost of developing them
for CAES. Locations of existing McIntosh CAES plant, recently announced Dallas Center
wind/CAES system, and proposed Matagorda plant are indicated. (From D. L. Katz and E. R.
