Allen Fossil Plant
TVA Seeks Public Input on Allen Plant Environmental Assessment
Review and comment on the draft Environmental Assessment for a proposed gas plant to replace the Allen Fossil Plant in Memphis.
Balancing efficient power production with environmental protection
Electricity is generated at Allen’s three coal-fired units by 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. Allen generates about 4.8 billion kilowatt-hours of electricity a year, enough to supply 340,000 homes.
TVA added 20 combustion turbine units at Allen in the early 1970s. These units can burn fuel oil or natural gas. They are designed to start quickly and typically are operated only during peak demand periods.
Low-cost and cleaner energy
Through 2011, TVA has spent about $5.4 billion on emissions controls at its fossil-fuel plants to help TVA generate power as cleanly as possible. This includes installation of selective catalytic reduction systems at Allen to reduce nitrogen oxide emissions by about 90 percent.
