Define consumption growth factor

Short answer

The annual rate at which a consumer's average electricity consumption (kWh/month) increases due to appliance acquisition and rising living standards. For n years, consumption grows as Eₙ = E₀(1 + g)ⁿ. It is distinct for each consumer class and separate from population growth.

Define consumption growth factor with respect to distribution consumer characteristics.

Consumption growth factor is the annual rate at which the average electricity consumption (kWh per month or per year) of a consumer of a given class increases, as consumers buy more appliances and use more energy with rising income and living standard.

If E0E_0 is the present average consumption per consumer and gg is the consumption growth factor (per year), the consumption after nn years is

En=E0(1+g)nE_n = E_0 (1 + g)^n

Example: 30 kWh/month with g=5%g = 5\% becomes 30×1.055=38.330 \times 1.05^5 = 38.3 kWh/month in the 5th year.

It is different for each consumer class (domestic, commercial, industrial) and is separate from the population (consumer number) growth factor. It is used in load forecasting to find the design-year peak demand of a load centre for sizing transformers and feeders.
