Seems like you can't start from a stop, as the posts above suggest. What a nightmare.

Systems off the top of my head that need power before you start up;
control systems, computers, motor operated valves instruments etc.
Lube oil systems
many different cooling systems for the other systems, oil, hydraulics, air compressors, bearing water cooling systems
cooling tower circ water pumps, tower fans
vacuum pumps for condensers, seal water systems for these pumps
condensate systems, feedwater systems, big pumps ours are 5000hp, some plants use steam driven feed pumps.
service water, cooling tower make up water.
demin water
generator cooling systems, we have one generator cooled by hydrogen and the other is water cooled.
you need all this up and running before you can start the plant. If our plant is already hot it still takes us 3 to 4 hours before we are generating, any residual steam and heat would not last long enough to get on line.
