In the desperation of battle, canny commanders will rig up whatever they can find to the laser weaponry to produce a steady and unrelenting arc of fire. Power generators come in all shapes and sizes, but the desired effect is the same: to enhance what is already present.
One-tenth the points cost of the fortification it is installed within.
A power generator causes all laser, plasma, melta, or other "energy" based weapons attached to a fortification to become twin-linked, representing an overload of power.
In addition, a single model in base contact with an appropriate type of weapon can "hook-up" that weapon to the power generator and gain the same effect.
The power generator is treated as an AV=10, open-topped immobile vehicle with 2 hull points. If it explodes, double the explosion radius and inflict an automatic strength 10 hit on the fortification that it is contained within.
