About Renegy

Renegy, based in Tempe, Arizona, is a green energy company focused on acquiring, developing and operating renewable energy facilities and providing emissions compliance solutions for the coal-fired power generation industry. We seek to rapidly grow our renewable energy assets with the goal of becoming the leading independent power producer (IPP) of biomass energy in North America. Our first project is Snowflake White Mountain Power (SWMP), a 24 megawatt (MW) biomass facility under construction near Snowflake, Arizona. This facility is scheduled to begin supplying electrical power to Arizona's two leading utility companies in the first half of 2008, and serves as a solid foundation for our growth. We also offer a variety of services for coal-fired power plants that use selective catalytic reduction (SCR) systems to reduce nitrogen oxides (NOx) emissions. These services are offered through our SCR-Tech subsidiary (www.SCR-Tech.com), and include SCR catalyst management, cleaning and regeneration, as well as consulting services to help power plant operators optimize efficiency and reduce overall NOx compliance costs.
