Hmm. The 100 Mw rating is only part of the story. The more pertinent figure is the capacity, something similar to the ampere/hour rating on a car battery. The Australian version is 129MWh and acts just like any other battery. One Mw for 129 hours or 100 Mw for 1.29 hours. People have to realize this is not a power plant that can generate power indefinitely. It will be interesting to see how the Texas version pans out.
