Cumberland Fossil Plant
Balancing efficient power production with environmental protection
Electricity is produced at Cumberlands two coal-fired units by the process of heating water in a boiler to produce steam. Under extremely high pressure, the steam flows into a turbine that spins a generator to make electricity. In a typical year, Cumberland generates about 16 billion kilowatt-hours of electricity, enough to supply 1.1 million homes.
Low-cost and cleaner energy
Through 2011, TVA has spent about $5.4 billion on emissions controls at its fossil-fuel plants to ensure that this power supply is generated as cleanly as possible. This includes installation of selective catalytic reduction systems that reduce nitrogen oxide emissions by about 90 percent and scrubbers that reduce sulfurdioxide emissions by about 95 percent at Cumberland.
