Presentation Transcript

  1. Strategic Plan and Economic Upgrade Process 2007 Transmission SummitJuly 31, 2007New Orleans, Louisiana

  2. Strategic Plan • 10-Year Study • 2015 Summer Peak • Develop alternate dispatch scenario to more closely reflect real-time dispatch • Review historical generation patterns to determine what generation does not typically run • Possibly run a minimum load case

  3. Strategic Plan: Goals • Address frequently TLR’d flowgates • Remove or reduce the need for RMR generation • Address frequently constraining flowgates in the AFC process • Address long-standing reliability problems • Webre-Wells • Sheridan South • Base case contingency overloads • Terminal equipment limited flowgates • Existing inter-area transfer limits • EES-SPP (ANO-Ft. Smith) • EES-SOCO • EES-TVA

  4. Strategic Plan: Goals • Tie in with SPP 765kV plans • Work with other RTO projects • Ozark study • Accommodate new generation interconnections • Improve existing import limits (Amite South, DSG, WOTAB)

  5. Strategic Plan: Specific Focus Areas • Acadiana • McAdams • Webre-Wells • DSG • Amite South • Arkansas 161 kV • Stability Limits • Mt. Olive – Hartburg • Webre – Wells • Franklin – McKnight

  6. Strategic Plan: Specific Focus Areas • Danville – N. Magazine • Mablevale/Little Rock Import • Western Region • El Dorado • Bogalusa • ISES, Whitebluff (possible double transformer contingency)

  7. Strategic Plan: This Year • High-level Analysis • Thermal & Voltage Analyses • N-1-1 in Load Pockets • Starting Point for Discussion

  8. Strategic Plan: Future • Stability • Short Circuit • More detailed analysis • Production Cost

  9. Economic Upgrades • ICT will identify potential economic upgrades based on: frequent TLR’s, frequently constrained flowgates, WPP results, RMR’s, etc. • Preliminary Analysis will be posted. • ICT will provide an estimate of potential benefits: increased MW flow, reduction in congestion, cost savings, etc. • Customers may request a study of a specific upgrade, including a Facility Study. • Separate Queue • NITSA/Pre-888, PTP Request, IOA/LGIA required to proceed with construction

  10. Economic Upgrades • Customers may fund upgrades at their discretion. • Any new dispatch made possible by an upgrade will be reflected in models. • ICT will report to regulators on Economic Upgrade activities.

  11. Super-Regional Summits • Continue to hold Entergy ICT Summit • Possibility of Entergy / CLECO / SPP / LAFA / ETEC / Other Transmission Owners Summit • Possibility of Entergy / SERC Region Summit
