    a = kWh of electricity entering system    45,629,456    44,037,981*    42,764,385*    44,532,248*
    b = Maximum demand                     7,903         7,820*         7,749*         8,062*
    c = Total number of hours in year        8,760         8,784          8,760          8,760

(b) Loss Ratio (=a/b*100)

    a = losses in electricity in kWh       4,460,951     3,955,387*     4,893,797*     4,289,870*
