Barkley Unit 1 Rewind nears completion
The rewind of Barkley Unit 1 is nearing completion after nearly one year of dedicated work by the district staff, NEC (contractor) and NEC’s subcontractors. The rewind was necessary following a fire in December 2010 that damaged the rotor and coils. An After Action Review and report determined that the best option for repair was to rewind the unit. In August 2012 the rotor was lifted clear of the unit and work began in earnest. The scope of work included replacement of stator coils, 23 rotor poles, cooling piping, inspection and repair of bearings as needed, and many other tasks. In June 2013, the rotor was lifted back into place during reassembly of the unit. Commissioning tests and start up are scheduled in early October.
District in process of updating its Hydropower Master Plan
In June 2013, the Nashville District began the task of revising the project list and rankings for the Hydropower Master Plan. This effort is in addition to previous work to revise the administrative organization of the LRN Hydropower and Section 212 Program team.
When completed, the Master Plan will explain how the district will administer the hydropower improvement program, and provide the listing of projects ranked by importance to the LRN mission of providing reliable economical energy to the power market.
The process outlined by David Mistakovich, chief of Hydropower, and Fred Ragan, acting Section 212 Program manager, will provide a deliberative look at the projects and rankings, solicit input from HDC, and allow review and comment by stakeholders such as the Program Review Committee. Upon District approval of the final draft, the Program Coordination Committee will be asked to approve the updated Master Plan. The Master Plan is scheduled to be sent to the PRC for review in late December 2013.
