Now if I find a power line that supplies 360kWs, or 360 kW a second I can only draw one point per casting
No. Just no. That's completely contrary to the physics.

A power line does not supply kWs; it supplies kW. kWs is not "kW a second," it's "kW sustained over a time of a second" or "kw times seconds." If it were "kW a second" the notation would be "kW/s." One is multiplying; the other is dividing.

And talking about "kW a second" is nonsense in this context. The kW is not a unit of energy; it's a unit of power. The unit of energy is the kJ (or kWs). A power line that supplies 360 kW is supplying 360 kJ a second; the "a second" is already there, built into the "kW." (That is, 360 kJ/s = 360 kWs/s = 360 kW.)
