Considering the City of Bangalore is generating Municipal Solid Waste to the extent of say 4500 metric tons per day , with a moisture content of 60 % the total volume needs to be reduced to say by 40 percent of the original mass to arrive at a MSW with appropriate calorific values in terms of BTU’s (British Thermal Units) .
It is at this point having a Refuse Derived Fuel Plant helps . This plant can generate the required fuel for generating electricity in the city, and at the same time if there is excess production in excess of the installed capacity the same can be sold to other units which required Refuse Derived Fuel , this process can also add to the revenues of the project.
Having arrived at say 2700 to 3000 tons of refuse derived fuel per day, we can easily assess the revenue generation at a gross level as under
3000 MTS will generate a minimum of 3000 MW of electricity per 24 hours .
3000 MW = 30,00,000 kwh say one unit of energy sold to KPTCL costs Rs. 6 per unit
30,00,000 kwh x Rs 6 = Rs. 180,00,000 per 24 hours of operation of the plant in terms of USD (USD @ Rs 50 ) = 360,000 USD per day X 30 days = 10.8 millions USD per month
Revenue generation per year would be 10.8 X 12 = 129.6 millions USD .
Out of the above if the Technology providers stake is even considered at 40 % per annum towards project costs , maintenance ,and other expenses , BBMP if it is a promoter /stake holder in the project would stand to earn USD 77.76 millions or say in Indian Rupees 388.8 crores per annum .
Please note all of the above workings are assumptions only, actual costing can be worked out only when we have business on the table.
