OK right now i'm having sub-station serving a marine for yachts with transformer 2×1000 KVA 11/415 KV permissible load transformer 640, total MSB

summer = 1639.342KW
winter = 1709.742KW

i want calculate the total load because i want make the load for each yacht 40 Amp. please i need the guid lines what i have to do starting from the sub-station to feeder pillar, cables all that and what if i want to control that marine with security system to keep people away from making by pass or any other thing?

For example, what is meant by "permissible load xfmr 640?"
