Grid batteries have to be flexible. That means discharging rates from slow to fast. Lithium batteries offer that sort of performance and they offer good storage performance for their size. Typically batteries described here come in a normal shipping container. The electronics are built in and one only needs to connect them to their own management system. The batteries can be used to augment the grid during high load times or they may be called upon to discharge in seconds during a planned switch from one power station to another thus keeping the lights on. In any case, the batteries offer additional flexibility for whatever power generating circumstances operators must deal with.
