NYSE-listed Ormat Technologies has just completed a 20 MW geothermal plant in Nevada. It took only 8 months to build - that must be one of the fastest large power plant constructions.

Since going public just over a year ago, Ormat has performed well, now trading in the low 20s, having reached a low of 14 in April this year. The company also takes an interest in recovered energy generation, remote power units and biomass fueled power units, although its major focus is in Geothermal. Ormat's recent Q3 results were strong; revenues rose 9.5 percent and net Income grew by 82%. And the company has a large market capitalisation of over $700 m - of major importance to Institutional Investors.

Its subsidiary, Ormat Funding Corp, has a much snazzier looking website. OFC was founded in 2001 to develop, construct, own, and acquire through certain direct and indirect subsidiaries geothermal power projects in the United States.

This company appears to have a major slice in the Geothermal market - and is publicly traded.
