That's a bit of a lost cause, there's no clean way to insert the explosion code. You can probably monitor the IEnergySink tile entities from the world's ticking TE list and check if they gained more energy than expected during a tick while not having a battery being discharged.
Ok, we could make some kind of add on to do that, sadly no one of us has coding knoledge, we are administrators. Could u help us or do u know someone that could? The server load is getting dangerously high.
