Nevada Geothermal Power Inc. completes independent resource review of Blue Mountain Project

VANCOUVER, Sept. 7, 2011 /PRNewswire/ – Nevada Geothermal Power Inc. (NGP) (TSX.V: NGP, OTCBB: NGLPF) announced today that it has completed a comprehensive independent review
of all resource information for the Blue Mountain project in order to
gain a better understanding of the geothermal fluid flow system and
ultimately to increase production from the Faulkner 1 geothermal power
plant.

The study concludes that:

      1. Deep western injection wells 55-15, 57-15, 58-15 and 61-22 inject
         cooled geothermal fluid from the power plant into the hottest
         known part of the geothermal field. Geochemistry of reservoir
         fluids predict that still hotter thermal water is present in this
         portion of the geothermal system.  Current injection of cooled
         water under pressure may be impeding hotter water from deeper in
         the fault structure from flowing up and eastward to the section 14
         production wells.
      2. Shifting current injection from wells 55-15, 57-15, 58-15 and
         61-22 to new well field areas along fault structures to the north
         and northeast would mitigate current well communication issues and
         allow for potential increased production from the power plant.
         Shifting injection may be achieved through stimulation of existing
         wells and by drilling new wells on identified structures.
      3. Geothermal reservoir host rocks are extensively altered and
         faulted. New injection targets are indentified on structures
         trending north and northeast.
      4. New production targets are identified on the deep structures to
         the west.
      5. The study makes recommendations for increasing injectivity at
         existing shut-in wells to help stabilize the production
         temperatures and further drilling to potentially increase
         production from current levels.

The study was conducted under contract by Engeocon LLC. Stuart Johnson,
principal of Engeocon, subsequently has joined NGP’s permanent staff to
help implement the Blue Mountain and other NGP resource development
programs. Mr. Johnson is a recognized authority on geothermal resource
development, having successfully reversed start up reservoir production
declines by redistributing injection fluids at the Dixie Valley and
Stillwater geothermal fields in Nevada. He directed field development
work at Steamboat Hills, Nevada that enabled expansion of production
capacity from approximately 35 MW when the property was acquired by
Ormat to approximately 90 MW today.
