this seems misleading. the article claims:

  12,000 megawatts, equivalent to 12 large nuclear plants, of energy from its battery arrays.

but for how long is this battery array able to produce this amount of power? compared to the nuclear plant, where the answer is years.

watts are power, not energy. for example, a tea kettle might require 2kilowatts. this does not tell you how much does it cost you to use the tea kettle, because it does not tell you how long the tea kettle is consuming 2kilowatts.
