Widows Creek Fossil Plant

Widows Creek Fossil Plant, named for a creek that flows through the plant site, is located on Guntersville Reservoir on the Tennessee River in northeast Alabama. In April 2005 Widows Creek Unit 3 set a national record for a continuous run by a coal-fired unit, operating for 819 days before it was shut down for scheduled maintenance. A new record was set when TVA’s Shawnee Fossil Plant Unit 6 achieved 820 days of nonstop operation in May 2006.
Balancing efficient power production with environmental protection
Electricity is produced at Widows Creeks eight 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.
Widows Creek generates about 10 billion kilowatt-hours of electricity a year, enough to supply 650,000 homes.
By 2010, TVA will have spent about $6 billion on emissions controls at its fossil-fuel plants to ensure that this power supply is generated as cleanly as possible, consistent with efficiency.
To reduce sulfur dioxide (SO2 ) emissions, Widows Creek Units 1 through 6 use a blend of low-sulfur coal, and Units 7 and 8 have wet limestone scrubbers. To reduce nitrogen oxides (NOX ) emissions Units 1 through 6 use combustion controls and boiler optimization. Units 7 and 8 have low-NOX burners and selective catalytic reduction systems.
