1 KV is 1,000 volts. 1 MW is 1,000,000 watts. They are different measures. It's like asking, "how many fat grams are in 10 pounds of food."

Multiply the watts by the seconds: 500 x 300 = 150,000 Joules is the answer.
You can rate a generator in any multiple you like. It's simply more convenient to express power as, say, 500 MW, rather than as 500 000 kW or as a fraction of a gigawatt. Incidentally, it's...kilowatts, not kilo wattsmegawatts, not mega wattsgigawatts, not giga watts
