1. Acadiana Load Pocket Project

3. Project Background Summer of 2002 Summer of 2005 Summer of 2007
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 TLR’s 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 5’s

4. 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.

5. 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.

6. ALP Project

7. 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.

8. 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.
