Mr. John Melvin:

Yes. As one of the many pieces of the complicated piece of software that has to be considered over the next period of time, batteries can be dispatched and are being dispatched. It is labour intensive on the side of the grid-scale developer and on the side of the system operator. There are many competing elements of the software that need to be upgraded. For grid-scale operators, the incremental cost of the manual intervention is likely to be small in the context of the overall investment.
