S-1 The US Electrical Power Industry : A 2003 Perspective

概要

論文の詳細を見る
A perspective on the current US Electrical Power Industry situation is provided. The main topics are : Most of the large increase in US generation capacity over the past 40 years was accomplished in several major building time periods that includes a surge of combustion turbine/combined cycle capacity during the past three years Future annual peak and total energy growth is expected to be less than in the past five years. Natural gas pricing was low for the past 10 years, but may become more expensive in the future. Coal and nuclear fuel prices have declined and are expected to be remain nearly constant in the future. US Environmental Agency mandated emissions reductions have substantially reduced the environmental impact of new and existing units. However, the trend for future additional reductions continues; especially for mercury and small particulate emissions. Currently there are a significant number of transmission lines operating near capacity. Eliminating these capacity restrictions is important to electricity supply reliability and pricing. Current generation reserve margins and diversity of supply should result in reliable service and slow rates of electricity price increases.
