North Metropolitan Electric Power Supply Company. The North Metropolitan Electric Power Supply Company provided electricity to the northern suburbs of London and to parts of Hertfordshire and Essex. Supplies of electricity commenced in 1907 and continued until the company was abolished in 1948 when the British electricity supply industry was nationalized.

Background 

The North Metropolitan Electric Power Supply Company (Northmet) was established in 1900 under the provisions of the North Metropolitan Electric Power Supply Act 1900 (63 & 64 Vict. c. cclxxvi). The act empowered the company to construct a power station at Enfield (Brimsdown) and to supply electricity to the boroughs and towns of: Hendon, Barnet, Edmonton, Ware, Hertford, Hatfield, Welwyn, St. Albans, Chingford and Walthamstow. This encompassed an area of 325 square miles. Further Acts of 1902, 1903, 1905, 1907 and 1909 extended the area of supply and permitted the company to purchase the power station at Willesden (Taylors Lane). Electric current was first supplied to Edmonton on 1 July 1907.

The North Metropolitan Electrical Power Distribution Company was registered on 19 April 1899.

The distribution company was vested into the Northmet Electric Power Company in December 1922.

The generating plant was vested in the British Electricity Authority and the distribution infrastructure in the Eastern Electricity Board.
