Broadcast Power
Broadcast Power is a fairly recent shtick in anime, and as such MTS doesn't cover it. Broadcast Power means that the mecha uses an external power source (like the extension cords of the Evangelions, or the Aestivalis that runs off power broadcast from the Nadesico). Similarly, the Qubeley from Zeta Gundam (and all MSs and MAs with Funnels) broadcasts power to its funnels, so they need no generator--which is why they're so small.
Broadcast power is an interesting kettle of fish, but with a reasonably simple solution. The advantages of using broadcast power are: 1) You can't have a Powerplant Explosion, since you have no Powerplant; 2) You might be a bit lighter or save some space in your Mek, since you don't have to hold the Powerplant (although you will need a collector system of some sort).
The disadvantages include the fact that you'll have a limited range which is dependent upon the broadcasting method (such as energy wave or extension cord), and the fact that your source of power is not under your own control, so you can't really guarantee its continued safety or reliability.
Because of this balance of advantages and disadvantages, Broadcast Power is a x0.0 Cost Multiplier (i.e., it doesn't affect your cost in any way). Essentially, it's a great big Special Effect.
Also worth considering is the possibility of limited onboard battery power which can allow the mecha to function for a short time if it is not receiving broadcast power. That's just a matter of buying an extra Power Cell for your Mek, which means paying the x0.15 as a POSITIVE Cost Multiplier RATHER than as a negative Cost Multiplier like it normally is.
