Abstract :
The factors that favor the transfer of electrical power, as opposed to generating it, when and where needed, namely economics and reliability, are discussed. The tie lines that connect utilities, transferring high-voltage AC or DC power, and the control of the interchange, are described. Problems and risks, particularly blackouts, are examined.<>
