  3. Regional Study Overview Map 5 2 1 3 3 345 kV 161 kV

  4. General Study Assumptions for Step 1 High-Level Analysis • MUST DC analysis of FCITC • Monitored and Contingent Elements • 115 kV and above elements within: • Entergy Zones adjacent to SPP • SPP Areas adjacent to Entergy • All elements 345 kV and above in SPP and Entergy • N-1 Contingency Scan (no breaker-to-breaker scan)

  5. General Study Assumptions for Step 1 High-Level Analysis, cont. • MDWG MOD Model 2014 Summer Peak • Incorporate Entergy’s Construction Plan Projects • Identical Source/Sink Transfer Analyses will be performed for all study projects • FCITC Changes from the Base Case will be identified • Planning-level cost estimates and construction timelines provided

  6. Source/Sink Areas for Transfer Analysis • SPP Areas • SPP (all) • AEP West • CLECO • OG&E • Empire District • SWPA EMDE SWPA OGE AEPW • Entergy Areas • Entergy (all) • Amite South • WOTAB CLECO Amite South WOTAB 18 Combinations, bi-directionally = 36 Combinations

  7. Entergy Net Interchange • 1471 MW Net Export to all areas • 1033 MW Net Export to SPP • Positive number indicates EXPORTNegative number indicates IMPORT
