Electric power industry capacity

In the United States, greenhouse gas emissions come from the following sources power plants (33%), transportation (28%), industry (20%), agriculture (7%), commerce (7%), and households (5%). A 500 mW coal-fired power plant releases 100 tons of COz every hour. The electric power generation capacity of the United States is around 1,000 gW (the equivalent of 2,000 such power plants). Counting all power plants, including the smaller ones, the total is some 16,000. 

PEAK LOAD PRICING - A pricing principle that charges more for purchases that contribute to the peak demand and, thereby, cause the expansion of productive capacity when the peak demand exceeds the peak capacity (less minimum excess capacity). In the electric power industry, this means charging more hr electricity bought on or near the seasonal peak of the utility or on or near the daily peak of the utility. The latter requires special meters the former does not. 

A.2.3 The Electric Power Industry The total corrosion costs in the electric power industry in the generation and distribution of power were estimated to be 4 billion and the corrosion-related expenditure was estimated at 1.1 billion. A significant portion of excess capacity of power plants was attributed to corrosion, where corrosion-related excess capacity was assumed to be approximately 10% of the total capital investment. 

The former Soviet Union constmcted a 262-km, 508-mm dia experimental coal slurry line between the Belovo open-pit coal mine in Siberia s Kuznets basin to an electric power plant at Novosibirsk, using technology developed by Snamprogetti. Testing began in late 1989 and tentative plans call for constmction of two much larger slurry pipelines, each 3000-km long, with capacity to move a total of 33 x 10 t/yr to industrialized areas near the Ural Mountains (27,33). 

Electrical power distribution within an industrial installation is most often at a voltage up to and including 33 kV. This section describes the types of cable suitable for power circuits for use up to 33 kV and considers the factors, which will influence the current-carrying capacity of such cables. 

Many dozens of industrialized countries now employ nuclear reactors for power generation, and some countries produce more electrical power by nuclear reaction than by fossil fuel combustion (France is an example). The United States, however, has the largest installed capacity of nuclear-powered boiler plants (in the year 2000 there are more than 120 nuclear reactor power plants in the United States). Nuclear power is also widely used for marine duty in both commercial and naval vessels.
