About NERC

• The electric industrys self-regulatory
  organization for reliability
• Balances the interests of all stakeholders
• Represents industry consensus
• Independently acts in the best interest of
  reliability
• International charter lending government
  support and oversight to SRO activities, ensuring
  that the best interests of society-at-large are
  represented
• Federally recognized Electric Reliability
  Organization in the U.S.
• Agreements in place with several Canadian
  provinces and developing these agreements in
  others

About NERC Mission
To ensure the reliability of the North American
bulk power system

• Develop enforce reliability standards
• Assess current and future reliability
• Analyze system events recommend improved
  practices
• Encourage active participation by all
  stakeholders
• Pursue mandatory standards in all areas of the
  interconnection

2007 LTRA Report
Integration of Wind Solar Resources Require
Special Considerations in Planning, Design,
Operation

• Operational challenges must be resolved
• Transmission needed to support renewable
  development
• Clean Energy Superhighway
• NERC to monitor federal carbon legislation for
  impact on reliability

5
NERCs Actions

• Evaluate operational requirements
• Recommend standards.
• Develop a consistent approach for rating variable
  resources
• Available capacity at time of system peak
• Developed Integration of Variable Generation Task
  Force

6
Engaging Industry Experts

• Integration must support a reliable bulk power
  system
• Variable Resources affect planning/operations
• Reviewed by the Operating Planning Committees
  in December 2007
• Integration of Variable Generation Task Force

IVGTF Scope

• The Task Force will prepare
• A concepts document that includes the
  philosophical and technical considerations for
  integrating variable resources
• Specific recommendations for practices and
  requirements, including reliability standards,
  that cover the planning, operations planning, and
  real-time operating timeframes.
• The document will include
• Planning timeframe issues, such as contribution
  to reserve margins and modeling requirements to
  test system reliability,
• Operational Planning and Real-time operating
  timeframe issues, including Interconnection
  frequency, and primary and secondary generation
  control
• Review NERC Standards for any gaps
• Conclusions and recommendations.

8
IVGTF Guiding Principles

• Bulk power system reliability must be
  maintained, regardless of the generation mix
• All generation must contribute to overall bulk
  power system reliability
• Standards and criteria established must be fair,
  transparent and performance-based
• Planners and operators must understand the
  challenges presented by large scale integration
  of variable generation
• Wind and other variable generation must
  effectively integrate into planning and
  operations practices to ensure reliability
• New Planning/operating tool requirements will be
  described in terms of bulk power system
  reliability performance

Emerging Issues Scenarios
13
2008 Key Findings Emerging Issues

• Collaborative Effort with NERC Staff
• Packaging
• Condense focus to no more than five key
  emerging issues
• Broader issues do not change year to year create
  separate document
• Divide Key Findings section into
• Key Findings from Regional Assessments
• Emerging Issues from the industry
• Specific Emerging Issues identified
• Progress from 2007 Report section

14
Risk Assessment of Emerging Issues

• Emerging Issues is critical driver for
• Assessment concentration
• Scenario analysis
• Industry experts to identify Emerging Issues for
  prioritization
• Ranking based on combination of likelihood
  severity (consequences)
• To manage expectations and speculation by
  regulators legislators about how utilities
  should respond to these issues
• To inform the policy debate

15
2008 LTRA Emerging Issues

• 7 Issues Identified by NERC Staff RAS,
  prioritized
• Greenhouse gas reductions
• Fuel storage transportation
• Rising global demand for energy equipment,
  increased off-shore manufacturing of raw
  finished materials
• Increasing adoption of demand-side distributed
  generation resources
• Replacing and upgrading transmission
  infrastructure for the 21st century
• Water usage
• Mercury emissions
• RAS will expand on a number of these in the 2008
  LTRA

16
Candidate Scenarios

• Should have significant impact on the reliability
  of the bulk power system
• Must be a future condition providing enough
  lead-time for assessment to inform a solution
• Selected with consideration for the definition of
  Adequate Level of Reliability
• Will be ranked by NERC PC based on likelihood
  severity

Emerging Issues Scenarios
Year 1
Year 2
LTRA Published
RAS Peer Review Scenario
PC assigns RIS, RAS TIS to develop list of
emerging issues
NERC Staff
Regions perform Scenario Reliability Assessment
PC agrees to scenarios for the following year,
based on risk assessment of emerging issues.
Scenario study outline peer reviewed by RAS PC
RAS assigns scenarios. Sends with LTRA Data
Request.
Regions develop Scenario Study Outline
18
2008 Emerging Issues Scenario Analysis

• Scenario 1 Study renewable integration in
  2009. If there is little or no impact of
  Scenario 1 on a region, then the Region must
  perform Scenario 2
• Scenario 2 A scenario picked by the Region for
  study in 2009
• Details of scenarios would be proposed by
  Regions, coordinated with RAS, and approved by
  the PC at June 2008 meeting
