Transformer Total Evaluated Cost Worksheet

Enter values from a supplier offer and your own evaluation policy. The worksheet estimates energy-loss cost; it does not predict an electricity bill or certify guaranteed losses.

Formula: annual no-load energy plus annual load-loss energy scaled by the square of buyer-entered average load factor. Taxes, financing, maintenance, reliability, downtime, escalation, residual value, and discounting are included only if you add them to “other evaluated costs.”
