Julia A. Souder
About NERC: Mission
Develop & enforce reliability standards
Assess current and future reliability
Analyze system events & recommend improved practices
Encourage active participation by all stakeholders
Pursue mandatory standards across North America
To ensure the reliability of the North American bulk power system
2007 & 2008 Emerging Issue Recap
Current Climate Initiatives
40 U.S. States and all Canadian Provinces are involved in some form of climate change initiative.
Key Objective: Address Fuel Switching
Early retirements & environmental dispatching of coal plants reduces available capacity
Gas delivery concerns
Gas as base load generation
Past Capacity Announcements vs. Actual Implementation
U.S. Coal-Fired Generation
Key Objective: Support Transmission
Climate objectives cannot be fulfilled without focus on transmission
“Clean Energy Superhighway” needed
System planning must take a “continental” view

Wind Availability Compared to Demand Centers
Note:o Blue indicates areas with high wind potential, o Brown indicates large demand centers, and o Green indicates areas with little wind potential and smaller demand centers
Transmission Needed

U.S. peak demand projected to grow by 17% by 2018
Key Objective: Decision on U.S. Policy
Regulatory certainty needed to enable resource development
Can result in great improvements
• New generation technologies
• Diversified fuel mix
• Strengthened & “smarter” grid
Wind Projected to Grow
145,000 MW of wind to be added in coming 10 years
Recommendations:
• Flexibility
• Forecasting
• Transmission

Integration of Variable Generation Task Force (IVGTF) Scope
Task Force will prepare: • Concepts document: philosophical
& technical considerations
• Recommendations: practices, requirements & reliability standards
Document will include:• Planning timeframe issues
• Operational Planning and Real-time Operating timeframe issues
• Review NERC Standards for gaps
• Review of future developments: i.e. storage, EHV
• Conclusions and recommendations
Smart, Modern Grids and Reliability
Planners can• Maintain Future Bulk Power System Reliability
• Change how they design grids
Operators can• More control
• Manage variability/uncertainty
• Pre-position systems
Regulators can• Implement formulas for cost allocation/cost recovery
• Provide certainty & support transmission infrastructure siting, planning, construction
• Flexible on innovative planning
Educators/policy makers can• Promote reliability as incorporating all components “fis”
flexibility- integration- smart
• Tell story with all pieces
