In this paper it is intended to survey generally the history and development of the power station industry which began in 1831 with a few simple discoveries and in a relatively short space of time became one of the primary factors in all spheres of modem life and perhaps the greatest single source of motive power, industrial and domestic. It is a tribute to all those who have shared in building up so great an enterprise that practically all essential processes have: made themselves dependent
upon electrical energy. There is hardly a comer of the world so remote as not to have come under its influence. Engineers can look back on the glory of past achievements
with pride, and forward with confidence to the almost superhuman efficiency of the first atomic station. Uskmouth Station, with many others now building, is a good example of the extento which practice has followed theory in our own day.
