Geothermal Energy
John McCaull
Geothermal Energy Association
The Earth Holds Enormous Energy
And it can be found almost everywhere
Overview: US Installed Capacity
Total Capacity: 3102 MW
2010 Capacity Addition: 15 MW, Nevada, Ormat
States with Capacity (MW): • California, 2566 • Nevada, 442• Utah, 42• Hawaii, 35 • Idaho, 16 • Alaska, 0.73 • Oregon, 0.28 • Wyoming, 0.25 • New Mexico, 0.24
What is happening with geothermal electric power
production in the US?The industry is building new
power plants!
Enel Salt Wells Power Plant
NGP Blue Mountain Faulkner No 1 Power Plant
Oregon Institute of Technology 280 kW Power Plant
US Installed Capacity
Geothermal Capacity Additions in 2010: 15 MW, Nevada Annual 2010 addition (15 MW) down from 2009 (176 MW)
Economic Downturn made project financing more difficult Permitting process delaying some projects
Capacity in Development
• Confirmed Geothermal Resources in Development: 3633 – 4050 MW• Confirmed + Unconfirmed Resources in Development: 4448 – 5040 MW• Planned Capacity Additions (PCA) in Development: 1377 – 1393 MW
– Advanced Phase PCA (Phase 3 and 4): 756 – 722 MW

Emerging Resources/New Applications Expand Reach of Geothermal Energy
• Small Heat and Power Systems – expand geothermal into distributed generation
• Co-production from oil/gas wells and geopressured resources –potential in many non-Western states, particularly the Gulf of Mexico.
• Enhanced Geothermal Systems/Deep Geothermal – potential nationwide and worldwide (witness recent Google announcement on finding 18,000 MW of geothermal in West Virginia!)
