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
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
NERC’s 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
IVGTF Outline of White Paper
 Characteristics of Variable Generation

 System Operations
 Other and Future Considerations
 NERC Standard Review
 Conclusions & Recommendations
 Glossary

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

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
