Generation,Transmission and distribution of…

Coal — Coal is burned to heat water, producing steam that drives the turbines.

To increase voltage and decrease current — Step-up transformers increase voltage to reduce transmission losses.

Generators — Generators are found in power generation plants, not distribution substations.

Reduced transmission losses — Higher voltage leads to lower current for the same power, reducing I^2R losses.

Substation — A substation steps down the high transmission voltage to lower distribution voltages.
