The early days of domestic electricity didn’t have the benefit of the National Grid, so individual suppliers built power stations to serve their local area. One of the pioneers in London was the Gatti family, who had made their money importing ice from Norway and America for the catering trade. The Gattis diversified, investing in restaurants and entertainment halls around Charing Cross, and were keen to use the new electrical lighting to draw in the crowds.
They even built their own power stations, including in 1902 a large one out here in Bow, running cables all the way to the West End to illuminate clubs, theatres and dining rooms.
