Entergy Transmission Planning Summit New Orleans, LA July 10, 2003

1. Generation and Transmission Developmentin the Southeastern United States Entergy Transmission Planning Summit New Orleans, LA July 10, 2003

3. SERC Generation Development Survey • Fifth annual survey • Survey request sent in late January • Information requested from Transmission Providers • All results received by early March Leading the Industry!!!

4. SERC Generation Development Survey • Collects 10 years of planned generation development • Categorizes facilities by interconnection status • Interconnection service requested • Interconnection agreement signed • Sub-categories indicate the amount of generation designated as a network resource • Reports aggregate, not plant specific, generation plant capabilities • Final results reported on Regional and subregional basis

5. SERC Generation Development Survey

6. 2002 Survey Projected Interconnected Generating Plant Capability in Commercial Operation Prior to June 1, 2002: (Summer Net Plant Capability in MW) 202,388 MW Total Actual Interconnected Generating Plant Capability in Commercial Operation Prior to December 31, 2002: (Summer Net Plant Capability in MW) 200,744 MW Total Merchant Generating Plant Capability in Commercial Operation Prior to December 31, 2002 : (Summer Net Plant Capability in MW) 26,399 MW SERC Generation Development Survey

14. Load Trend vs. Projected Total Capacity

16. SERC Generation Development Survey • Total projected generation capacity for Summer ’03 (222,960 MW) exceeds projected Summer ’03 load (157,941 MW) by 65,000 MW • Total connected generation capacity at the end of last year exceeds projections for SERC Regional load in 2012 • Projected capacity additions indicate sufficient generating resources over the long-term planning horizon

17. SERC Generation Development Survey • SERC Generation Development survey accurately projects actual generation development for the following year • Survey reflects recent decline in proposed generation capacity additions • Survey projects generation capacity additions of 73,000 MW over the next 10 years • Projected capacity additions for the same period have declined by 61% in the past year • Network resource additions continue to be a small percentage of the projected capacity additions in the Region

18. SERC Transmission Development Survey • Second annual survey • Survey request sent in late January • Information requested from Transmission Providers • All results received by early March Leading the Industry!!!

19. SERC Transmission Development Survey • Requests total planned transmission expenditures • 5 years of cost data • 100 kV and above • Requests aggregate data for transmission projects, only • New lines • New substations • Line rebuilds • Substation rebuilds • Line reconductoring projects • Excludes distribution station costs • Results available on a Regional and subregional basis

20. Transmission Development Expenditures- Projected 2002 versus Actual 2002 -

21. Transmission Development Expenditures- Projected 2002 versus Projected 2003 -

22. Survey Result Comparisons- Total Projected Expenditures - 2002 Survey Results Total Projected Transmission Expenditures Over the Subsequent Five Years : $6.932 Billion 2003 Survey Results Total Projected Transmission Expenditures Over the Subsequent Five Years : $6.265 Billion

23. Survey Result Comparisons- Cumulative Annual Expenditures -

24. SERC Transmission Development Survey 2003 Survey Results Total Projected Transmission Expenditures Over the Subsequent Five Years : $6,265 Million 2003 Survey Results Of the Total Projected Expenditures Over the Subsequent Five Years, Amount Attributed to Direct Interconnection of Generation : $191 Million

27. SERC Transmission Development Survey • Actual spending in 2002 fell short of projected spending acquired from last year’s survey • Cancellation of generation may have contributed to a portion of the decline • Shortfall was minimal, indicating real spending has been occurring on the SERC transmission systems • Projected spending for next five years (beginning in 2003) is slightly below five-year projected spending from 2002 • 2003 survey projected spending correlates well with 2002 actual spending
