1893 Norwich Electrical Supply Company (or the Norwich Electric Light Company) began to supply an electricity service in the city; the Duke Street Generating Station was on the south bank of the River Wensum; it generated 180kW direct current.
1896 Detailed description, with some plans, of Norwich Electric Light Station in Engineering. Designed mainly by Laurence, Scott and Co. 'Six sets of engines. All are of the Willans type, and are triple-compound. Three of these engines are of 100 indicated horse-power each, and each of these engines is connected to two "Norwich" dynamos manufactured by Messrs. Laurence, Scott, and Co. at their works ; these dynamos will work from 110 to 130 volts. The object of having two dynamos to one engine is that only one engine is required for running at the lightest loads. Of the remaining engines three are of 135 indicated horse-power; the dynamos which they drive — one to each engine — are also of the "Norwich" type made by Messrs. Laurence, Scott, and Co., and will work from 220 to 250 volts. A seventh Willans engine, capable of giving 200 horse-power, has been more recently added, and is now running regularly. It is also coupled to a “Norwich” dynamo....The boilers are of the Babcock and Wilcox type; they are four in number, two having been added since the station first began to work. [1]
1897 the plant had a generating capacity of 850 kW
1900 A new engine room and a boiler house were built to house new generators.
1902 The supply company was purchased by Norwich Corporation. The electricity undertaking was then known as the Norwich Corporation Electricity Works.
By 1903 there were 13 machines ranging from 100 to 700 horsepower supplied with steam from Babcock and Wilcox coal-fired boilers.
