RE: we have exactly 1 plant under construction and it was approved in 2007.
Where is this plant located?
"Watts Bar 2
"While the focus is on new technology, TVA undertook a detailed feasibility study which led to its decision in 2007 to complete unit 2 of its Watts Bar nuclear power plant in Tennessee. The 1177 MWe reactor is expected to come on line in 2013 at a cost of about $2.5 billion. Construction was suspended in 1985 when 80% complete and resumed in October 2007 under a still-valid permit, and is progressing on time and budget. Its twin, unit 1, started operation in 1996. Completing Watts Bar 2 utilizes an existing asset, thus saving time and cost relative to alternatives for new baseload capacity. It was expected to provide power at 4.4 ¢/kWh, 20-25% less than coal-fired or new nuclear alternatives and 43% less than natural gas."
