Title: Strategic Plan and Economic Upgrade Process


1
Strategic Plan and Economic Upgrade Process
2007 Transmission Summit July 31, 2007 New
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 TLRd 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 TLRs, frequently constrained
    flowgates, WPP results, RMRs, 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
