Clean-energy pledges made at the Clinton Global Initiative in New York include one from a company that's looking at Nevada as a possible site for a big solar-thermal power plant.
John O'Donnell of Ausra Inc. says Ausra committed to development of solar-thermal plants that will generate 1,000 megawatts of power.
The Palo Alto, Calif.-based company plans to start with a 175-megawatt plant.
Also Thursday, San Francisco-based Pacific Gas and Electric pledged to buy 1,000 megawatts of solar power over the next five years, and Florida-based FPL Group said it would develop plants that would produce another 500 megawatts of solar-thermal power.
O'Donnell said a key reason for Nevada being considered by Ausra is a plan by Nevada-based Sierra Pacific Resources to build a cross-state power transmission line at a cost of nearly $600 million.
