www.standardandpoors.com - Standard & Poor's announced today that it has commenced Factual Stock Report coverage on Sierra Geothermal Power Corp.

Sierra Geothermal Power Corp. (SGP) (TXV:SRA) is developing its geothermal properties held for the potential commercial production of electricity. Sierra Geothermal's pipeline of projects have a combined total estimated capacity of 500 megawatts. The company

intends to advance the development of its portfolio of projects through a combination of equity and/or joint ventures, while continuing to evaluate additional acquisitions.

As of August 2008, five of the company's properties were being actively developed. Its top five active projects (or tier one sites) include the following: Reese River, Pumpernickel, Silver Peak, Alum and Barren Hills. All tier one sites are located in Nevada near transmission infrastructure.

Sierra Geothermal intends to move its top five projects to financial feasibility, and then engage an experienced contractor to construct a power plant on a turn-key fixed price contract. Its target goal is to advance these tier one projects to power generation within the next five years. The additional projects within the company's pipeline provide for continued growth into the future.

This report will also be accessible on an ongoing basis to the investment community -- scores of buy-side institutions and sell-side firms that utilize S&P research and information platforms daily. Millions of self-directed investors also have access to the report via their e-brokerage accounts.
