The County of London Electric Supply Company Limited (C.L.E.S.Co) was a British electricity undertaking. It was incorporated as a public company in 1891 to generate and supply electricity to parts of south west London and two parishes adjacent to the City of London. It owned and operated power stations at Wandsworth and City Road. From 1925 it cooperated with three other London companies, with the intention of centralising electricity generation in the new, high thermal efficiency, power station at Barking. The company was abolished in March 1948 upon the nationalisation of the British electricity supply industry.
