considering that he is specialised in power engineering or does he administers them.
Electrical engineers would be primarily interested in the driven equipment namely the generators. They might be involved to a slight degree in the design of engines and turbines but not to the extent that a mechanical engineer would.
Turbine engines (either steam of fuel-injected) are mechanical parts and not electrical parts. A electrical engineer will be working on the generator that is attached to this systems. They will also work on the transmission of that power (Transformers and all that good stuff!).
