Till yesterday we have discussed various aspect of Land requirement for Thermal Power Station . Day by day the problem of getting Land at required location becomes acute . Study is already on to reduce the area by re engineering , using superior technology , using fuel mixture etc . A few aspect is now being given for viewers for their knowledge and comment pl.
a. Power stations classified as Pit head / load centre oriented. but using indigenous coal
Power station size 2x500MW to 5X800MW( UMPP) the area requirement varies from 20 to 100 acre. All other power stations like 3x660MW, 4X660, 4X800MW etc falls in between the above
limit.
b. Power station classified as Coastal based using imported coal
India is having a vast coast line and due to economic and financial reasons IPPs tend to use coastal stations with large capacity ( 5x800 MW/6x660MW etc) with imported coal near coast line.
The limit sets by expert committee for 3x660MW to 5x800MW is 30 to 65 acre. It is observed that the land requirement due to category (b) is much lesser than the (a ) mainly due ash content of coal.
It is assumed that indigenous coal having 45% and imported coal is 10% . These values were taken
for Land area calculation..
Above limit value was given only for Main Power House area. Coal storage and handling also requires considerable area . Same was categorised again with the above concept .
For pit head station of 2x500MW to 5x800MW with indigenous coal the land requirement varies from 220 to 250 acres. Variation is much less .
For coastal stations having imported coal the land requirement varies from 150 acres to 200 acres
for 3x660MW to 5x800 MW with MGR ( Merry Go round ) rail but the requirement is much less for
coal conveyor system . The value for same size power stations is 108 to 150 acres.
Next day we will summarise the total land issues and move into our next topic.
