An enhanced geothermal system (EGS) generates geothermal electricity without natural convective hydrothermal resources. Traditionally, geothermal power systems operated only where naturally occurring heat, water, and rock permeability are sufficient to allow energy extraction. [ 1 ]
The company currently has a demonstration project underway about 30 miles south of Bend, Oregon in the Deschutes National Forest.The Newberry EGS Demonstration [5] is located on an existing Federal lease designated for geothermal use and is supported by a committee that includes representatives of the community, environmental groups, government and the geothermal industry.

Closed-loop geothermal systems (also known as “advanced geothermal systems” or “AGS”) are a type of engineered geothermal energy system containing subsurface working fluid that is heated in a hot rock reservoir without direct contact with rock pores and fractures.: [1] [2] [3] Instead, the subsurface working fluid stays inside a closed loop of deeply buried pipes that conduct Earth’s ...
A lack of fluid production indicated these rocks are impermeable and that the site is a classic example of a hot dry rock energy system. [9] The thermal grounds cover most of the northern Milford valley. [13] [14] The highest temperature wells (greater than 80 °C) are located east of the OMF above the RHS hydrothermal system. [14]
The act gives the Chairman of the Project the authority to designate an appropriate Federal agency to guarantee loans for the commercial applications of geothermal energy. The head of the designated agency is authorized, in consultation with the Secretary of the Treasury , to guarantee loans from lenders to qualified borrowers for the ...

A 2006 report by the Massachusetts Institute of Technology (MIT) that included the potential of enhanced geothermal systems estimated that investing US$1 billion in research and development over 15 years would allow the creation of 100 GW of electrical generating capacity by 2050 in the United States alone.
