  TEPCO : Thermal | Power Generation
Steam power plant facilities constitute a means of power generation that uses the expansion power of steam.
This turns the power generator, which is directly connected to the turbines, and electricity is produced as a result.
With advanced combined cycle (ACC) power generation, the inlet gas temperature of the gas turbine is raised to 1,300°C, higher temperature and pressure levels are established as in the steam conditions in the steam turbines, and a reheating cycle is also employed to improve the thermal efficiency.

 Power Generation
Although some electricity comes from nuclear power, hydroelectric power and other renewable forms of energy, on the whole most power generation in the world is still reliant on the burning of fossil fuels.
Fossil fuel power stations are a major source of air pollution, from poor air quality and acid rain, to global warming.
The burning of coal, oil and gas in power stations releases a number of air pollutants, including sulphur dioxide, nitrogen oxides and carbon dioxide.

Electrical power is a little bit like the air you breathe: You don't really think about it until it is missing.
Power is just "there," meeting your every need, constantly.
It is only during a power failure, when you walk into a dark room and instinctively hit the useless light switch, that you realize how important power is in your daily life.

 Power to the people   (Site not responding. Last check: 2007-10-15)
In the early 20th century, electric power was generated by cogeneration plants in industry, by a few federal hydropower plants, and by electric utilities.
By 1955, 53 percent of power generation came from coal, 6 percent from oil, 18 percent from natural gas, and 22 percent from hydro.
In 1998, primary power generation resources converted to electricity were coal, accounting for 52 percent; nuclear, 19 percent; natural gas, 15 percent; oil, 4 percent, and hydro, 9 percent.

 Editorial   (Site not responding. Last check: 2007-10-15)
Once again, the power ministry is making a fresh move to invite proposals from the private sector to establish small power generating plants having capacity between 10 and 30 mw each.
Subsequently, however, the power ministry suspended the process saying that the selection criteria needed amendments and the project implementation responsibility was shifted to the Power Cell of the ministry from the Power Development Board.
Without questioning the wisdom of the power ministry's decision last year to suspend the processing of small private sector power plants, it is difficult to understand the rationale of the new move to confine foreign entrepreneurs' share in the small power plants to 49 per cent.
