1889 At the enquiry into the future of the competing electricity systems in London, General Webber, managing director of the Chelsea Company, highlighted the problem of distribution and the danger of several companies competing to supply electricity in one small district. The Chelsea's chosen system was the DC system. The Anglo-American Brush Electric Light Corporation had installed a generator at Chelsea and the Electric Power and Storage Co had supplied batteries for 3 distributing stations; the batteries would be able to supply for 7 hours at full rate without recharging being necessary. Mr T. O. Callender, engineer of the company, had experience of laying hundreds of underground mains installations; he was very concerned about the possibility of 2 or 3 companies trying to lay mains in the same street .
1890 February: Two additional battery sub-stations had been added since the system came on line in April 1889 and a fourth was being added. Current was supplied to users only from the batteries, thereby avoiding the fluctuations experienced in some other systems connected directly to the generators
