  Power station - Wikipedia, the free encyclopedia
A power station (also power plant) is a facility for the generation of electric power.
At the center of nearly all power stations is a generator, a rotating machine that converts mechanical energy into electrical energy by creating relative motion between a magnetic field and a conductor.
In thermal power stations, mechanical power is produced by a heat engine, which transforms thermal energy, often from combustion of a fuel, into rotational energy.

 Power plant operators, distributors, and dispatchers
Power plant distributors and dispatchers control the flow of electricity from the power plant, over a network of transmission lines, to industrial plants and substations, and, finally, over distribution lines to residential users.
In older plants, the controls for the equipment are not centralized, and switchboard operators control the flow of electricity from a central point, whereas auxiliary equipment operators work throughout the plant, operating and monitoring valves, switches, and gauges.
A decline in employment of power plant operators, distributors, and dispatchers is expected through the year 2012, as the utilities industry continues to restructure in response to deregulation and increasing competition.

 Power Plant Manager
Plant managers soon learn that the technical aspects of the job notwithstanding--managing power loads, controlling production and inventory, and handling the continuous maintenance chores--the heart of managing a power plant is managing people.
Plant managers who embrace both these aspects of the job are the most successful at this career.
A power plant is maintained and operated by hundreds of workers, and the manager coordinates all activities.

 EPA - Mercury - Controlling Power Plant Emissions
Approximately 75 tons of mercury are found in the coal delivered to power plants each year and about two thirds of this mercury is emitted to the air, resulting in about 50 tons being emitted annually.
This 25-ton reduction is achieved in the power plant boilers and through existing pollution controls such as fabric filters (for particulate matter), scrubbers (for SO 2) and SCRs (for NOx).
Currently none of these technologies are in commercial operation on power plants in the U.S. but EPA expects these technologies to play a role as EPA and states require reductions in mercury emissions.
