[en] A study was conducted to project photovoltaic (PV) module characteristics for the 1995 timeframe, and conceptual designs and cost estimates were developed for four 50-MW PV plants. Design performances were modelled for the conditions at two sites in California and Florida. Hypothetical but realistic utilities were formulated for each site for the purpose of assessing the economics of the PV plants. The capacity value and production cost analysis were used in an overall economic assessment of the PV plant designs. Environmental externalities associated with the displacement of hydrocarbon fuels were taken into account. Other factors considered included the year of installation of the technology and the module production volume. Sites with the highest insolation were found to be able to support economically viable projects in the near future if investors can receive credit for project environmental benefits and overall PV demand can support a 25 MW/y production facility. Between 65% and 75% of the total benefits of the designs studied were associated with energy displacement, so future economics will be highly sensitive to future fossil fuel costs. Air quality benefits amounted to 18-25% of total project benefits and capacity benefits were 4-10%. 3 refs., 2 figs., 9 tabs

[en] This paper evaluates LNG versus coal for future generating plant additions for a power utility company in the Far East. The paper considers the supply, contracting provisions, transportation, receiving, and storage of LNG. Three power generation technologies were also evaluated to determine capital, operating and maintenance costs. The three technologies were pulverized coal (PC) fired units with and without wet flue gas desulfurization (FGD), gas turbine combined cycle (GTCC) units, and integrated gas turbine combined cycle (IGCC) units. The IGCC plant was based on the Shell gasification process. The evaluation considered lad additions to the system in 1000 MW blocks from 500 MW to 6000 MW. Three simplifying cases were considered
