Electricity is so basic to the world economy that certain electricity indices are used to

express a country's economic standing (consumption or production of electricity per capita)

and the standard of living enjoyed by a people (per capita electricity consumption in the

domestic sector). Moreover, electricity supply has special characteristics which make the

service unique as compared to other types of industry. The end product has to be delivered

instantaneously and automatically upon the consumer's demand; except for pumped

storage plants and electric batteries, technologies do not exist that can produce it

economically at uniform rates, hold it in storage in large quantities, and deliver it under

convenient schedules; insufficient capacity (shortage) or excessive capacity (idle capacity)

have negative effects on the economy; the close inter-relation with economic and social

factors imposes labour, environmental, financial and other constraints on the problem.

Careful planning of the electric sector is therefore of great importance since the decisions

to be taken involve the commitment of large resources, with potentially serious economic

risks for the electrical utility and the economy as a whole
