This report defined the technical development, developmental capacity, commercial status, costs, and deployment constraints of selected electric generation technologies. First phase technologies included: geothermal; fuel cell; solar thermal; solar photovoltaic; wind and hydro. Phase II technologies included biomass as well as other non-renewable technologies. The focus was on development and application of the technology in California. The most recent cost information and assumptions were utilized. In addition to the comprehensive report sections on each technology, two-page fact sheets on each technology and a matrix comparing all technologies and the above variables were developed. Finally, an updated discussion of renewable technologies was developed for insertion into the alternatives section of Staff Assessments for power plant applications.
