Costs of Environmental and Performance Attributes of the Colorado Electricity Sector

This study offers a practical example of how environmental and performance adders might be calculated for environmental and performance attributes. The study reviews secondary data and provides marginal damage estimates of environmental and performance attributes associated with electricity generation in the state of Colorado. Low, mid-point, and high values are calculated for five environmental pollutants: mercury, carbon dioxide, nitrogen oxide, sulfur dioxide, and fine particulate matter. Marginal damages are also calculated for intermittent electricity.
