Abstract :
In an attempt to make the subject manageable, I intend to present three `snapshots¿, so to speak, of the electricity supply industry at different points in time rather than attempt to cover the entire continuum. In the `yesterday¿ section, I shall try to set the scene with a description of what the supply industry was like in the late 1930s, a period which coincides with the start of my career. This can be compared with the supply industry today, and I shall pick out the important and interesting developments and changes that have taken place. Finally, in the `tomorrow¿ section, I shall attempt to give an impression of what the industry might be like in the future with special consideration to the problems it is likely to face
