1. Loss Evaluation
For the purposes of tender evaluation the 400/138.6kV transformer (and where applicable the 400kV
reactor) losses will be capitalized, in the following manner:
Transformers
No-load loss (NLL)
2932 US$/kW at rated voltage
Load loss (LL)
688US$/kW at rated MVA and voltage
Reactors
No-load loss
2932 US$/kW at rated voltage

2. Penalties
A maximum variation of +10% of the total declared losses (TL) is permitted. Any transformer or
reactor with losses more than +10% of the Total Loss (TL) declared will be rejected, unless otherwise
agreed by the Engineer.
For transformers or reactors with total losses within +5% of the declared losses no variation of the
contract price will be made.
For transformers or reactors where the total losses are between +5% to +10% of the total declared
losses the contract price will be reduced by the total capitalised cost of losses in excess of the
capitalised cost of the declared guaranteed losses.
For any transformer or reactor with total losses less than 100% of the guaranteed losses, no variation
of the Contract price will be made.
