  1. Critical factors in computing externalities for electricity resources.

    Article - En anglais

    The New York State Environmental Externalities Cost Study and computerized externality model (EXMOD) are used to examine the specification of methods design and application factors in the computation of electricity externalities.

    We report the sensitivity of externality estimates with alternative specifications for 15 different factors in the analysis, including the selection of facility type, site, and operating characteristics ; air emission assumptions and air modeling procedures ; dose-response assumptions ; economic valuation assumptions ; and other modeling procedures and assumptions.

    Many of the factors that most influence externality computations can be well specified in the analysis, such as the facility type, age, characteristics, emission rates, whether there is SO2 trading, and the inclusion of long range impacts.

    Most significant among the factors for which there remains significant scientific uncertainty are the selection and application of air dispersion models, selection of air pollution thresholds for health impacts, reduced life span risks associated with ozone exposure and with long-term exposure to PM10, values for CO2 damages, and the value to be applied to increased risks of reduced life span for individuals age 65 or older.
