Generation efficiency is calculated by dividing the gross amount of electricity generated at BC Hydro facilities by the sum of electricity the facilities use and losses that occur during generation. It does not include imports or purchases.

Internal energy efficiency for transmission and distribution systems is the ratio of the net or useful energy output (in the form of sales or deliveries to internal distribution systems) to the gross energy input to these systems (in the form of net generation or energy purchases). It is less than 100 per cent due to cumulative losses from BC Hydro's own use, from sending the power down the lines, from illegal tie-ins, and converting or conditioning it at substations and pole transformers.

Energy generated, transmitted or distributed per employee is one measure of productivity. The number of Full-Time Equivalent employees (FTEs) is the weighted sum of all full-time and part-time employees. Due to ongoing improvements in operations, the average remains competitive with other Canadian utilities - public and private.

The efficiency indices are not always directly comparable to Canadian Electricity Association composites because of slight differences in calculation methodology. Transmission Efficiency provided by BC Transmission Corporation (BCTC). It is not yet possible to calculate Distribution Efficiency separately due to current equipment configurations.
