The context here was EMP to be deployed against nanobots, not power grids. The source will thus be optimized to produce EMP, and to minimize collateral damage against general infrastructure—perhaps by producing smaller pulses closer to the target rather than enormous pulses further away.
In particular, the ability to affect microelectronics is paramount. The ability to take down the grid is irrelevant.
