    Capitalization Losses - The inter se ranking of the offers will be arrived after adding the All inclusive rate of one unit quoted by the tenderers and present worth of the transformer (K) after taking in to account the capitalization losses. This is as per Annexure-5 of the RDSO specification no. TI/SPC/PSI/TRNPWR/3201. The formula for capitalization losses as per CONDITIONS (attached) is as under :- K = D{ ( 1 + i ) power n-1} / { i (1 + i ) power n } Where K = Present worth of transformer in Rupees. D = Annual cost of combined no-load and Load losses in Rupees. i = rate of compound interest on unit price of transformer @ 12% per annum. n = Life of transformer = 50 years. Substituting value of D, which is : D = ( I + F square C ) X 365 X 24 X T divided by 1000. I = Maximum No- Load loss in watt. C = Maximum Load - Loss in watt. F = Load factor , T = Tariff in Rupees. Considering F as 50% and T as Rs 6.77 per kWh, the value of K is, K= 59.31 (I+0.25 C (1+0.12)50-1 /0.12 (1+0.12)50 The Value of K = 492.50 (I+0.25 C). Note: If transformer losses at the time of inspection exceeds the capitalization losses quoted by the firm in its offer then unit rates (quoted by the firm) will be subjected to reduction by the exceeded capitalization losses as per the capitalization formula stipulated in the specification. The firm quoted Capitalization Losses as per Annexure- 5.NOTE:- Inspection authority:- TPI may please note that the ordering on the firm is on the basis of calculation of capitalization of transformer losses of 132/27 KV transformer as on their offer (maximum load loss in principal tapping C =85000 watt and no load loss I=9000 watt) and the same considered for evaluation of its inter- se-ranking of offers. The relevant particulars of the parameters mentioned in Annexure-5, which must be insured by the supplying firm. If transformer losses exceed the guaranteed values prescribed above at the time of inspection of transformer the price will be subject to reduction as per capitalization formula stipulated in the annexure-5. However no adjustment will be done if losses are on lower side.
