Incorporated Association of Electric Power Companies
of London
R. P. Sloan, president
Most of the member companies had been granted rights of supply in perpetuity, and so were not subject to the possibility of being purchased by local authorities, as was the case for the electricity supply companies.
1927 Of the 26 coal-fired power stations owned by members of the Association at the time the Central Electricity Board was established, all but 3 were chosen as "selected stations".
1927-32 The facilities offered by members in terms of supply had resulted in 300 privately owned generators in their areas being taken out of service.
