TVA Board Approves Plan to Complete Second Reactor at Watts Bar
LCG, August 2, 2007--The Tennessee Valley Authority (TVA) Board yesterday approved plans to complete the second unit at Watts Bar Nuclear Plant in Spring City, Tennessee. TVA stated that the additional capacity, which is scheduled for completion by 2013, will help serve the growing demand for electricity without increasing carbon emissions.
Watts Bar Unit 2 will add approximately 1,180 MW of electric generating capacity to TVA's supply portfolio at an estimated cost of $2.49 billion.
Watts Bar Unit 1 began operating in 1996, and Unit 2 will use the same pressurized water reactor design as Unit 1.
TVA stated that the Board approval is founded upon a detailed scoping, estimating and planning study; an environmental review; a power supply assessment; and a financial and risk analysis.
In concert with adding capacity to meet long-term power demands, TVA also stated that it has set a goal to reduce electric demand by about 1,200 MW by 2012 through energy efficiency and demand-reduction initiatives.
Prior to pursing the completion of Watts Bar Unit 2, TVA completed the refurbishment of Browns Ferry Unit 1 in May 2007. The reactivation of Unit 1, mothballed over 20 years, added 1,200 MW of carbon-free electric generating capacity to TVA's fleet.
Browns Ferry Unit 1 originally commenced commercial operation on August 1, 1974, but safety concerns following a fire led to its closure in 1985. Units 2 and 3 were also closed for a period but returned to operations in the late 1990s. All three reactors are now generating power, and the total plant capacity is approximately 3,600 MW.
The TVA Board voted to return Browns Ferry Unit 1 to service in May 2002. The plant upgrades cost an estimated $1.8 billion, and the plant returned to service on schedule.
