What is the electricity supply?

Two steam turbo-generators in the engine room produce 200 kW of 225 volts direct current each while diesel generators in the gearing room and #1 boiler room can produce another 100 kW each when needed. Two 50kW motor alternators in the fwd and aft KVA rooms produce 440 volt ac and motor generators in the Low Power Room produce 22 volts dc.
