The Clean Energy Superhighway

• Industry Focus
• Keeping Reliability in the Balance
• Integrating Renewables
• Climate Change Legislation
• Working Together

3
Challenges to Reliability

• NERCs 2007 forecast projects load will grow 20
  over the next ten years
• The grid is being operated closer to the edge
  than ever before
• Rising dependence on natural gas for generation
  just as North American demand begins to exceed
  on-shore supply
• New transmission needed to support wind and other
  renewable development
• On the cusp of dramatic change as climate change
  and carbon legislation are considered

4
2008 Emerging Issues

• Greenhouse gas reductions carbon legislation
• Fuel storage transportation
• Rising global demand for energy equipment,
  increased off-shore manufacturing of raw
  finished materials
• Modeling increasing adoption of demand-side and
  distributed generation resources
• Replacing and upgrading transmission
  infrastructure for the 21st century
• Water usage
• Mercury emissions

5
2009 Scenario Analysis

• Accommodate a minimum of an additional 15 of
  total energy from new renewable sources by 2018
• No more than 5 made up from energy efficiency /
  demand response
• Stretch case

6
Keeping Reliability in the Balance

• 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

Integrating RenewablesTransmission as Ultimate
Enabler

• Moving power from the source to demand centers
• Clean Energy Superhighway
• We need just as much support for transmission
  development as we do for renewables
• States must work together to bring these clean
  resources from areas where renewable resources
  exist to areas where they dont

Integrating RenewablesOperational Tools

• Operational models wind forecasting tools
• Use geographic diversity varying wind patterns
• Strong transmission back bone
• Demand-side management
• Interconnection facilitators
• Low-voltage ride through
• Dispatchability

11
Integrating RenewablesInnovation

• New technologies are needed to manage variable
  generation integration. For example
• Storage
• Compressed Air Energy
• Plug-in Hybrid Electric Vehicles
• Flywheels battery
• Smart Grid
• Better visibility leads to higher productivity,
  efficiency, flexibility

Climate Change LegislationResults

• Drives higher penetration of demand response and
  energy efficiency
• Accelerated retirement of less efficient coal
  plants
• 59 planned coal plants cancelled or deferred in
  2007
• Environmental dispatching of existing generation
  to achieve emissions targets
• Further expansion of natural gas

13
Climate Change LegislationAnalyzing Reliability
Impacts

• Need transmission
• Power flow implications resulting from
  geographical disbursement of gas plants vs. coal
  plants
• Possible strain on gas pipeline system
• NERC to take active role in shaping legislation,
  making sure voice of reliability is heard

14
Moving Forward Collaboration

• NERC-EPRI joint effort to define reliable
  integration and identify technology requirements
• Industry Challenges are bigger than any one
  organization
• Requires cooperative, industry-wide action
• Accelerated investment is required

15
The Clean Energy Superhighway

• The time is now
• We need renewables, we need the transmission to
  move the power they generate
• Industry-wide collaboration required to support
  this effort
• Operational issues exist, but emphasis must be on
  solving them
