1. Integration of Variable Generation Task Force (IVGTF)
Mark Lauby Manager, Reliability Assessments

2. About NERC
The electric industry’s “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 2

3. To ensure the reliability of the North American bulk power system
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

4. 2007 LTRA Report Operational challenges must be resolved
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. NERC’s Actions Developed Integration of Variable Generation Task Force
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

7. IVGTF Scope The Task Force will prepare The document will include:
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
