US Geothermal secures transmission agreement for Idaho geothermal power project

BOISE, ID, Jun 27, 2005 -- Canada NewsWire

US Geothermal Inc. , a renewable energy development company focused on geothermal energy, announced today that it has signed a service agreement for firm, point-to-point power transmission with the Bonneville Power Administration Transmission Business Line (BPA). The agreement guarantees up to 12 MW of electrical transmission capacity, an amount that accommodates the planned power production from phase one of the Raft River project.

"This transmission agreement with the Bonneville Power Administration marks a significant milestone in our development of the Raft River geothermal project", said Daniel Kunz, President and CEO. "We now have a secure delivery path to our customer for the electrical power generation from our first power plant at Raft River."

In addition to the point-to-point transmission agreement, US Geothermal has reserved an additional 24 MWs of transmission capacity with BPA to insure that the phase two expansion plans have adequate transmission available when it is needed.

About US Geothermal:

US Geothermal is a renewable energy development company that is in the process of developing a geothermal power project at Raft River, Idaho. The Company possesses three Power Purchase Agreements with the Idaho Power Company for the production of 30 MW of electricity at Raft River. Construction of the Phase One power plant is planned in 2005 and power production is planned for 2006. On the basis of a report prepared by Company's independent consultant, GeothermEx Inc., of Richmond California, the Company believes that Raft River's energy reservoir is scalable to produce an estimated 90 MW of power from 6.5 square miles (16.8 square kilometres) of lands owned or leased by the Company. Adjacent to the existing electrical transmission grid and surrounded by modern infrastructure, Raft River is ideally located to make an important contribution to the power needs of the rapidly growing Pacific Northwest for decades to come.
