Fossil-fired plants account for approximately 47% of SCE&G's electric generation capacity. For detailed information on a specific fossil-fired plant, select one of the power plants below.

Facts About Fossil-fired Plants

• Fossil plants are the most common type of power plant.
• Two-thirds of SCE&G's electricity comes from fossil plants.
• Steam is used to turn a fossil plant's large turbines.
• Steam is created by one of the three most common fossil fuels -- natural gas, oil, or coal.
• Coal is the most common fossil fuel used, and is usually hauled in by train.

How A Fossil-fired Plant Works

• Coal, ground into a fine powder, is burned inside a boiler producing steam.
• Steam spins blades on the turbine which turns the generator producing electricity.
• Steam is cooled in a condenser by water from a nearby river or lake. The cooled steam, now water, returns to the boiler and the cycle is repeated.
• The cooling water returns to the lake or river. The water goes through cooling towers before reentering a river. This prevents environmental problems that could occur from warming the river.
• Electrostatic precipitators in the stack clean up exhaust gases.
