This is irrelevant - each shot also requires a highly precision engineered piece of metal called a hohlraum to be destroyed.
With current technology, running an ICF plant would cost literally hundreds of millions of dollars per hour in hohlraums, since a single one costs millions, and you need to shoot several times per minute to produce energy.
That's why ICF is not even close to being a plausible electricity generation technology, so it is only being researched by nuclear weapons research labs like LLNL.
