2008/12/4 · How Coal Power Plants Produce Electricity. The conversion from coal to electricity takes place in three stages. Stage 1. The first conversion of energy takes place in the boiler. Coal is burnt in the boiler furnace to produce heat. Carbon in the coal and Oxygen in the air combine to produce Carbon Dioxide and heat. Stage 2.
