TVA’s Watts Bar 2 hits 28% power generation

The Tennessee Valley Authority (TVA) Watts Bar 2 nuclear unit was listed at 28% power generation early June 13, according to daily reactor data posted by the Nuclear Regulatory Commission (NRC).

Watts Bar Unit 2 was officially synced to the grid on June 3 and TVA operators continue to gradually increase power generation at the roughly 1,150-MW facility in Spring City, Tennessee. Eventually, as testing continues, TVA will increase power generation to 100%.

Watts Bar 2 is the seventh operating unit in TVA’s nuclear fleet. TVA has placed the total estimated project cost at $4.7bn for completing construction of the second pressurized water reactor (PWR) at Watts Bar and bringing it online.

The unfinished Watts Bar 2 reactor project had sat idle for many years when the TVA board voted to complete the facility and take advantage of its carbon-free generation.  When the TVA board approved completion of the long-suspended Watts Bar 2 project in 2007, it predicted a 60-month construction schedule and a cost of $2.49bn.
