Solving the (Expensive, Imported) Energy Dependence Problem:
• Values and Vision– Energy Self Sufficiency• Goals
– Economic – Affordable Energy – Reduced Utility Bills, Business and Job Development
– Social – Community (fate control), Social Metrics
• Project/Timeline– Resource– Research– Investment– Generation

What we know today
• Location of upflow zone (within ~30 meters)
• Depth to bedrock
• Good estimate of available heat (~20-40 MWth)
• Indication of larger regional geothermal system

Next/Current Steps
• Drill one 35 cm (14 inch) diameter hole that will allow us to extract fluid to ‘stress’ the resource and measure response to develop a more accurate reservoir model.
• Pump up to 7500 liters per minute (2000 GPM) (upper limit) for a period of 5-20 days, and discharge at surface.

What We Hope To Do
• Produce at least 2mW of geothermal energy from pilgrim hot springs
• Build a transmission line to Nome• Deliver sustainable, affordable
energy by end of 2014
