U.S. Policymaker Goals
  • Addressing rising electricity demand while
    reducing power plant emissions
  • Ensuring electricity remains affordable, reliable
    and secure from domestic sources
  • Moderating electricity price increases
  • Sustaining the engine of economic growth
  • Increasing environmental protection

4
Key Points
  • No silver bullet Portfolio mix of resources
    will be required to satisfy future energy needs
  • Expected federal environmental policy will
    require further emissions reductions from
    existing and future coal and natural gas fired
    power plants
  • Carbon capture and storage and EOR are critically
    needed technologies for baseload generation to
    comply with anticipated federal CO2 emissions
    reduction requirements
  • Financial market recovery is necessary to enable
    the transformation of a decarbonized portfolio

How can these reductions be achieved?
  • Technology developed and quickly deployed
  • Establishing enabling public policies
  • Financing through public/private partnerships
  • Investment recovery from ratepayers

12
CO2 Capture Techniques
  • Post-Combustion Capture
  • Conventional or Advanced Amines, Chilled Ammonia
  • Key Points
  • Amine technologies commercially available in
    other industrial applications
  • Relatively low CO2 concentration in flue gas
    More difficult to capture than other approaches
  • High parasitic demand
  • Conventional Amine 25-30, Chilled Ammonia
    target 10-15
  • Amines require very clean flue gas
  • Modified-Combustion Capture
  • Oxy-coal
  • Key Points
  • Technology not yet proven at commercial scale
  • Creates stream of very high CO2 concentration
  • High parasitic demand, gt25
  • Pre-Combustion Capture
  • IGCC with Water-Gas Shift FutureGen
  • Key Points

Mountaineer CCS demonstration project
2009 Commercial Operation
Alstom
Mountaineer Plant (WV)
Chilled Ammonia
CO2 (Battelle)
  • Project Validation
  • 20 MWe scale
  • (Scale-up of Alstom/EPRI 1.7 MW field pilot at
    WE Energies)
  • 100,000 tons CO2 per year
  • In operation 3Q 2009
  • Approximate total cost 80 100M
  • Using Alstom Chilled Ammonia Technology
  • Located at the AEP Mountaineer Plant in WV
  • CO2 for geologic storage

Will capture and sequester 100,000 metric tons of
CO2/year

Major issues
  • Storage issues
  • Property rights
  • Liability
  • Permit requirements
  • USEPA designation of CO2
  • State cooperative agreements/consistency
  • Capture issues
  • CO2 absorption
  • Steam requirement for liberation of CO2
  • Power plant integration and optimization
  • Parasitic load

17
Complimentary Technologies Toward a Cleanly
Powered Grid
  • AEP is investing in these new technologies
  • New advanced coal technologies to gasify coal and
    carbon capture to retrofit to existing and new
    coal and natural gas units with storage or for
    enhanced oil and natural gas recovery
  • Renewable energy (especially Wind, Biomass)
  • Supply and demand side energy efficiency
  • New nuclear units
  • New transmission infrastructure to make our
    system more efficient
  • Offsets (Forestry, Methane)
  • Power to Change Deployment Plan at www.wbcsd.org
  • Midwest Governors Association Energy Stewardship
    Platform At www.midwesterngovernors.org

18
Todays Challenges….
  • Why change now?
  • Generation profile is shifting and will continue
    to shift dramatically
  • New large scale renewables need to be
    interconnected that are today largely
    electrically isolated
  • Environmental requirements may require
    retirement of large fossil units, potentially at
    a magnitude never before faced in this country
  • Generation needs to be deliverable to load not
    simply interconnected. Attention must be focused
    on the robustness of the grid.
  • The search for a bright line between
    reliability and economic projects is increasingly
    artificial.
  • What needs to change?
  • A new energy supply paradigm requires a different
    type of transmission planning to enable greater
    capacity and flexibility.
  • Cost allocation principles must be broadened to
    encompass this strategic new build.
  • Siting processes which are aligned with state,
    regional and national energy policy objectives.

Efficiency of 765-kV Transmission
Advanced transmission enables energy savings
through efficiency.
A US 765-kV transmission overlay would reduce
peak load losses by more than 10 GW and CO2
emissions by some 15 million metric tons annually.
