The Electricity Business - Introduction The electric power industry can be defined to be the generation, transmission, distribution, and sale of electric power to the general public. Reliable and economical electric power has become a requirement for normal operation of all elements of developed economies The Electricity Business is a complicated web of consumers, producers, services, operations, markets, and regulations Once entirely constructed as a vertically integrated monopoly, it is now undergoing restructuring and conversion to new structures featuring competition and new services Ref [1,2,3]
The Electricity Business - Introduction The Electricity Business is a complicated web: Consumers Generation Transmission Distribution Operations Delivery Chain Operations The Market Structures (Traditional and Restructured) Market Dynamics Regulation Ref [3]
The Electricity Business - Introduction Key physical properties Electricity cannot be stored (easily or economically) Supply and demand must be continually balanced Electrical flow path is difficult to control Electrons follow the path of least resistance Disturbances travel quickly and are hard to contain Electricity moves at nearly the speed of light Outages and voltage and frequency fluctuations are not acceptable Minute-by-minute monitoring required Ref [3]
