GRED ProgramGeothermal Resource Exploration & Definition
  • Goals and Objectives
    • Develop collaborative efforts to support the exploration for and definition of new geothermal resources
      • Mitigate The Initial Risk Of Confirming A Reservoir
      • Encourage Geographic Diversity
    • Effect an increase in the electrical power generated from geothermal energy
      • Increase Overall Generating Capacity (40,000 MWe)
    • Promote additional geothermal development to aid development of technology
      • Decrease the levelized cost of geothermal energy

GRED ProgramGeothermal Resource Exploration & Definition
  • Program Approach
    • Original Geographic-Diversity Focus
      • GRED (2000)
        • New States, New Fields, Extensions
        • Now Closing Out
      • GRED II (2002)
        • New States, New Fields
        • Generally In Phase II Work
    • New Risk Focus
      • GRED III (2004)
        • New Solicitation
    • DOE Cooperative Agreements
      • Preferred Contractual Instrument
      • Flexibility

GRED Science & Engineering Areas

Geophysics

Drilling

Phase I :

Exploration geophysics to determine optimum location for a test well

Phase II :

Drilling of a test well to

access the reservoir and evaluate geologic features

Fourmile Hill Temperature Logs (454° Max)

Steamboat Hills Velocity Model

Testing

Assessment

Phase III :

Testing of the well for

reservoir qualities, flow capacity & thermal characteristics

Potential of the new resource to provide geothermal power

gred iii program
GRED III Program
  • New FOA
    • Release In Late March, 2004 (DOE/GO)
    • Initial Awards In Late FY04
    • Risk-Based Approach
      • High Risk (Unpenetrated Thermal Anomaly)
        • 80% Maximum DOE Cost Share
      • Medium Risk (No Production In Anomaly)
        • 50% Maximum DOE Cost Share
      • Low Risk (In Vicinity Of Producing Reservoir)
        • Requires Advanced Technology
        • 20% Maximum DOE Cost Share
    • Premium On Advanced Technology
      • Additional Cost Share For Appropriate R&D Usage

  • Conclusions
    • Successful GRED I Program Is Nearly Complete
      • 7 Projects Funded: Close-Out Stage In Most Projects
      • 4 Projects Should Progress Through Phase III
      • Significant Potential In These Sites
    • GRED II Ongoing
      • 8 Projects Funded
      • 4 Projects In Phase II; 1 Project In Phase III
    • New GRED III
    • Overall Program Is:
      • Successfully Encouraging New Exploration & Reservoir Confirmation
      • Contributing To Overall Geothermal Program Goals & Objectives
      • Connecting Projects With New Technology
