It depends on the size of the plant, and it's generating capacity. Most coal powered generating plants cost in maintenance about $1.00 per megavolt-ampere-hour of generating capacity in maintenance (non-fuel) cost, annually.
So a 450 MW generating plant will cost about $86 million dollars per year to maintain all the operating systems. Upgrades and refits add to this cost, and this does not include salaries of the plant workers. These costs are often averaged over 3-5 years, as generating units are not taken offline every year but every 3 to 5 years.
it depends on how big the power station is
Yes,once its used as much oil and coal power station
Ferrybridge is a coal powered power station.
coal
CO2 is formed in a coal fuelled station when coal is burnt and the carbon it it combines with oxygen and leaves carbon dioxide
kendal power station in south Africa
lignite coal
the coal is crushed first then the coal is passed for burning
Current
yes
yes a coal is nature nuclear uses lots of power Process for production of power from coal is very inefficient , More over it produces lot of carbon dioxide in to atmosphere (harmful green house gas). While Process for production of power from Nuclear plant is very good when compared with coal power. But initial and maintenance cost is very high. Unit cost for coal power is more economical than nuclear power. So economically coal power station is better. But on the basis of efficiency Nuclear power stations are good. When the deaths caused by the two types of mining are considered, coal fired systems have a much higher overall death rate. But the coal mining industry is improving this.
does it come from the Huntly coal fields, or is it imported from overseas.
