TENDER EVALUATION
1.15.1 Capitalization of Transformer Losses
When evaluating the individual bid received from various Bidders, the transformer shall be evaluated for
the cost of losses based on the following relation
PE = Pb + KL x LL + KNL x LNL
PE = Evaluated Price
Pb = Bid Price
KL = Value of Load Loss
LL = Guaranteed load losses at rated current (Maximum MVA base)
KNL = Value of no load Loss
LNL = Guaranteed no load losses
The transformer losses shall be capitalized as follows:
Value of No Load Loss
= US$ 4,684.00 per KW
Value of Load Loss
= US$ 1,180.00 per KW
1.15.2 The Bidder shall furnish guaranteed no load and full load loss data at rated load with the bid for al
rating of transformers contained herein. The supplier shall furnish a test certificate for each transformer
supplied, which shall show the actual no load and full load losses of the transformer at rated load. For
the purpose of evaluation, the higher values of no-load and load losses shall be considered from the
values guaranteed by the Bidder and the values given in the test reports.
1.15.3 If the actual no load and full load losses of any transformer exceed the guaranteed values then the
contract price for that transformer shall be reduced by the following calculated amounts for the losses
in excess of the guaranteed values:
No Load Loss
= US$ 4,684.00 per KW
Load Loss
= US$ 1,180.00 per KW
Any transformer shall be rejected if losses exceed the guaranteed value by an amount in excess of the
following
Total losses: 10%
Component losses: 15% (unless the total loss exceeds 10 %)
