Well you're probably right that this could reduce the amount of load coming from power plants during brownouts, but the article presents it as something that is going to protect against blackouts and I really can't imagine that working as a replacement for peaker plants. If you're in silicon valley or NYC you probably think of a blackout as something that happens once or twice a year for about 15 minutes but in a lot of the country blackouts are several hours or even days long and happen fairly frequently.
