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

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.

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
