Project Background

• Summer of 2002
• load growth, changes to generation dispatch in
  the Acadiana Load Pocket (ALP) and reduced
  ratings on lines which were damaged during
  Hurricane Lili result in TLRs with in the ALP
• Summer of 2005
• Wells Substation was built which provided an
  additional source to the ALP and provided more
  import capability into the ALP
• Summer of 2007
• Company specific imports are established which
  reduce the number of TLR level 5s

Project Background Continued

• SPP coordinates a joint planning effort with
  Cleco, Entergy and LUS
• Group evaluates multiple options to fix
  reliability concerns and provide possible
  economic benefits
• In January 2009 Cleco, Entergy, LUS reach
  agreement on a project to be built with each
  party having some responsibility for the
  construction.

ALP Reliability Concerns

• Difficult to perform maintenance on transmission
  system even during off peak conditions (N-2)
• Catastrophic loss of Teche 3
• Operationally the configuration is N-1,G-1
• Rolling blackouts within the ALP
• Voltage concerns
• 2012 N-1 Summer Peak overloads with all
  generation in the ALP online.
• Rolling blackouts within the ALP.

Reliability Benefits

• Plans the ALP to N-1, G-1 which will prevent load
  shed in the event of a extended outage on Teche 3
  or Bonin 3.
• Creates additional 230 kV sources into the ALP
  which will provide maintenance and operational
  flexibility.

Economic Benefits

• Majority of economic benefit will be in fuel cost
  savings for Cleco and LUS who currently have must
  run requirements on generation within the ALP
  during certain times of the year.
