SERC Y2k Contingency Planning Principles

• Contingency Plans will be developed by SERC
  members using the NERC Contingency Planning Guide
  as a reference document
• SERC Security Coordinators will facilitate
  development of Control Area plans.
• SERC Y2k Contingency Planning TF will aggregate
  Control Area plans into the SERC Plan.
• SERC members will cooperate with other regions to
  accomplish coordination of Contingency Plans on
  interregional and interconnection basis.

7
Operating Entity Contingency Plan Development

• Each Operating Entity (OE) in SERC developed a
  Y2k contingency plan
• OE s include all SERC Control Areas and Operating
  Entities with large loads and/or generation
• Contingency Plans followed pattern of the NERC
  Contingency Planning Guide

8
Operating Entity Contingency Plan Assessment
Process

• The OE plan assessment included all SERC Control
  Areas and Operating Entities with large loads
  and/or generation.
• Each plan was assessed for completeness and
  quality for each step of the six step NERC Y2k
  Contingency Planning Process.
• Strengths and Weaknesses were identified for each
  OE plan, and feedback was given.

9
Operating Entity Contingency Plan Assessment
Process

• Each plan was assessed for completeness and
  quality for each step of the six step NERC Y2k
  Contingency Planning Process.
• Identify Y2k Operating Risk
• Scenario Risk Assessment
• Develop Risk Management Strategies
• General Preparations
• Power System Operation Planning
• Implementation of Y2k System Operating Plan
• Strengths and Weaknesses were identified for each
  OE plan, and feedback was given.

SERC Operating Entity Plans

• Strengths
• Risk Identification
• Risk Mitigation Strategies
• Followed the NERC Contingency Planning Guide

• Areas for Improvement
• Implementation Plans
• System Study Scope
• Restoration Coordination
• Intra- and Inter-Regional backup control center
  communications

13
SERC Y2k Contingency Planning Status

• All SERC Control Areas have started some level of
  contingency planning
• The majority of SERC Control Areas have made
  strong progress into Steps 3 and 4
• All SERC Control Areas have increased their
  contingency planning emphasis

14
SERC Scenario Analysis

• The SERC Y2K task force identified general
  scenarios to be considered by each operating
  entity
• The individual risk factors identified within
  SERC were used as the basis for these scenarios
• Each individual operating entity was then
  responsible for developing appropriate and
  detailed scenario analysis for their system.
• Coordination and review of these individual OE
  scenario analyses is being accomplished at the
  SERC level.

15
SERC Scenario Analysis
In general, the scenarios identified by the
operating entities within SERC fell into the
following categories

• Loss of Generation (moderate / significant)
• Loss of Transmission (partial / significant)
• Loss of Load (moderate / significant)
• Loss of Telecommunications - EMS/SCADA or voice
  (partial / significant)
• Combination Scenarios
• Loss of Generation, EMS/SCADA, communications
• Loss of Generation, Loss of Transmission
• System Restart

16
Proactive Mitigation Strategies (Operational
Strategies)

• Generation
• Development of a unit commitment and operating
  plan that will allow significant flexibility for
  various scenarios.
• Recommend a limited number of planned transfers
  between control areas.
• Minimize transaction schedule changes for
  critical Y2K periods.
• Man essential system facilities
• Make backup provisions for critical system data
  and voice communications
• Identify procedures for validity checks of
  critical system data
• Coordinate pumped hydro operation

17
Proactive Mitigation Strategies (Operational
Strategies)

• Transmission
• Man critical facilities
• Minimize or eliminate planned facility outages
• Instigate voltage control strategies
• Review facility voltage schedules
• Verify transmission devices (capacitors,
  reactors, etc.) are working properly and respond
  to control.
• Develop procedures to adjust generation to
  support voltage.
• Coordinate with Security Coordinators to reduce
  the effects of parallel and/or loop flows.
• Identify procedures for validity checks of
  critical system data

18
Proactive Mitigation Strategies (Operational
Strategies)

• Telecommunications
• Establish backup communication procedures
  (control center to control center, control center
  to critical facility)
• Establish backup facilities for critical system
  data and voice communications
• Identify procedures for validity checks of
  critical system data
• Perform training for backup communication
  procedures

19
System Studies

• Minimum Load
• Voltage Control
• Islanding
• Black Start
• Underfrequency Operation
• Transfer Capability
• Load Loss
• Transmission Congestion

Contingency Planning Discoveries

• EMS remediation/replacement efforts are critical
• Backup communication is a concern
• Current assessments continue to indicate that
  operating risks are low for Y2k periods
• Consideration of time zone diversity is necessary

22
Spring 1999 Work Plan
23
Future Activities

• Further coordinate intra-SERC contingency plans
• Improve coordination efforts with neighboring
  regions
• Identify operational efficiencies available by
  coordinated response
• Review and coordinate SERC black start plans
• April 9 Drill
