Selection and Location of Power Plants: 14 Considerations

For steam plants, the cost of coal for the boilers and the availability of coal are important considerations. If cheap oil is available, the boilers may be oil fired and steam plants may complete other types of power plants. Steam power plants are most economical near coal mines and by the side of river or canal.
