Power
generation cost: It
is the amount of rupees spent on generation of 1 unit of power
Power
export cost: It is
the amount of rupees spent on export of 1 unit of power
Generally power generation actual cost is the sum
of Fuel cost, man power cost, operation & maintenance costs administration
cost, river water cost, plant gardening & vehicles cost etc
Power generation & Export cost in
Thermal power plants:
Part A:Fixed data
- Total
power generation in KWH = A1
- Total
power export KWH = A2
- Rate of
per ton of fuel in = A4
- Raw water consumption per day in MT or M3 = A5
- Rate of per ton or of river water in = A6
- Rate of per unit power for lifting water from source to Reservoir Rs= A7
Part B:
Operation cost head wise
- Cost of fuel in Rs B1= A3 X A4
- Cost of raw water in Rs B2 = A5 X A6
- Cost of chemicals consumed for water treatment = B3
- Cost of fuel feeding in =B4
- Cost of raw water lifting charges from river to reservoir= B5
Total operation cost C = B1 + B2 +B3 + B4 + B5
Part C:
Maintenance cost head wise
- Cost of spares,consumables consumed = C1
- Cost of store inventory= C3
- Tools tackles testing cost = C4
- Measuring instruments calibration cost = C5
Total maintenance cost C = C1 +C2 + C3 + C4 + C5
Part D :
Administration cost head wise
- Cost of O &M man power salary = D1
- Cost of site expenditures = D2
- Cost of gardening labours salary =D3
- Cost of Security guards salary = D4
- Cost of transportation vehicles =D5
Total administration cost = D = D1 + D2 + D3 + D4 + D5
- Total Cost of production, E = B + C + D
-
- Power
generation cost per unit =A1/E....Rupees/KWh or Dollars/Kwh
- Power export cost per unit = A2/E.....Rupees/KWh or Dollars/Kwh
Note:
1-In calculation power generation
cost, power consumed for plant auxiliary running should not be considered
2-In co-generation plants:
- Cost of power given to process
plants should be considered
- Cost of process steam given
should be considered for power generation cost calculation
